Method to record the Savings 3.4.2 Residential Buildings Five Belgian residential buildings (Verbeeck, et al, 2005) Five reference existing buildings based on a statistical analysis were chosen to represent the average residential types in Belgium. The choice of good insulation to roof, glazing and heating system will account an energy savings ranging from 36% to 60%. The energy savings are drawn up in the table 3.2. Table 3.2 - The Energy Savings of GEB technologies inputs for the five Belgian residential buildings Major GEB Technologies used | - Insulate on roof and floor;
- Use thermally better performing glazing ;
- Input renewable energy using photovoltaic cells.
| Method to record the Savings | Building imitation and use of NPV technique Based on the above GEB case studies of different types of existing buildings, the top five most acceptable GEB technologies in terms of potential cost benefits can be identified as follows: (Burton, 2012) - Energy savings equipment selection
- Low /energy savings lamps (T5 fluorescent)
- Time control trigger
- Motion control and
- Light-emitting diode (LED) as a source for lighting
This correlates with the study by (Thomas Ng, et at, 2014) identified by a questionnaire survey carried out in most of different districts in Hong Kong from June to July 2013. However, more GEB case studies on different types of buildings is required to confide the existing building owners/end users to adopt the above greening strategies for the improvement of their existing buildings’ sustainable performance. 4. Green Rating Systems for Existing Buildings-Green Audit Award [GAA] Green rating systems adopted so far with common global coverage are: - LEED (Leadership in Energy and Environmental Design) mainly used in USA and Canada,
- BREEAM (Building Research Establishment Environmental Assessment Methods) in UK and
- GREEN STAR in Australia and New Zealand.
LEED is a globally recognized symbol of excellence in green buildings. Commencing from 2007, the United States Green Building Council has developed a LEED Green Building Rating Systems for Existing Buildings: Operations and Maintenance or LEED-EBOM/LEED-EB for short. LEED-EB has laid down those green standards that the existing buildings should be addressed to for retrofit before the buildings can be certified as a green building. LEED-EB applies to all existing residential, offices and civic buildings of all sizes. Its goal is to maximize a building’s energy efficiency and the indoor air quality if those green standards as laid down in LEED-EB are complied with thus enhancing the health and comfort of its occupants while minimizing the building’s adverse environmental impacts. It gives building owners and operators a verification system and an effective benchmark in a design perspective to guard the green improvement/retrofits and maintenance over the life cycle of an existing building. However, up to this moment, there is no green rating system that has been designed for assessment of the existing buildings at their status quo. Based on the LEED-EB version 4 released in November 2013, with some modification to suit the climate and type of existing building stock in Hong Kong, a green audit award (GAA) plan will be established to assess the green standards of the existing buildings aiming to reveal which area and what green strategies/technologies should be adopted to upgrade the existing building to maximize operational/energy efficiency while minimizing environmental adverse impacts. Unlike LEED-EB, GAA does not put forward any green standards, instead, the subject existing building will be assessed/certified under a GAA plan. After the GAA assessment, a unique green improvement plan will be derived based on the green deficiencies identified in the assessment if the subject existing building is not certified as green. This will enable the existing building can be sustainably improved in a cost effective and energy efficiency manner pursuant to the characteristics/constrains/peculiarities of the subject existing building. Thus, GAA gives the owners of the building with a distinctive green mark that elaborates its whole energy savings performance/deficiencies. It seeks to - Dig up the green deficiencies/potentials of the existing buildings with the aim of setting a set of green improvements so as to make the existing buildings more green with the least costs and time;
- Stimulate the users/owners to perform the most cost effective green measures that are affordable and within the constraints of the subject existing building;
- Enhance the quality and green performance of existing buildings
Based on the LEED-EB protocol, and the international consensus building assessment on performance, the Green Audit Award (GAA) plan will take a complete view of the sustainable performance of the buildings in existence on their operation/maintenance within their whole building life cycle. GAA incorporates many key performance data of the existing buildings, inclusive of: - Local transportation in relation to the use of public transport;
- Recycled materials usage , and refuse disposal arrangement;
- Water usage and its cleanliness ; and
- Energy conservation and distribution;
- Internal air quality, thermal , visual and audio comfort
GAA assessment scheme for all buildings in existence will include all buildings types like those residential, office and civic. GAA not only evaluates the actual sustainable performance of an existing building, but also it will postulate its green potentials so that the building can be turned green with ease and low cost effectively. The various aspects of sustainable performance in GAA are grouped within the following 10 classifications. 1.Location & Transportation [LT] Using of public transports is highly recommended so as to reduce air pollution. It is highly favored for the internal estate transportation given that enough parking facilities are available. A bicycle-sharing system, or bike-share scheme is encouraged to operate within the large estate now dominates one-third of existing buildings in Hong Kong. Bicycles can be made available for shared use to individual on a very short term fee basis. This bike share scheme can allow people within the estate to borrow a bike from point A and return it to point B, for instance, from home to the MTR station. A credit will be awarded if this service is available in the subject existing building under assessment. 1.Sustainable Sites [SS] This includes the assessment of the buildings in existence of their: - location/orientation ;
- odor releases like harmful gases from the building site; and
- site administration
2.Water Efficiency [WE] The assessment under this category includes: - water usage and cleanliness
- waste water discharges
3.Energy & Atmosphere [EA] 6.Economic Value [EV] The assessment will be based on those performance that can achieve significant, measurable added value with reduced energy and raw materials performance. The economic value will include: - achieve targeted energy cost reduction; and
- optimize waste reduction/ energy efficiency performance with added value
7.Human Impacts [HI] Encourage for tenants involvement/social participation should be made if the performance of buildings can be improved significantly. This includes impacts: - on the inferior groups like the disabled and the aged group with age above 60 years; and
- lifestyle and convenience of the tenants e.g. ease in marketing with good hygiene and covered facilities
Table 4.1 GAA 4-rating bandwidth | SUSTAINABLE SITE [SS-10] | Site set up –reserve existing natural state To facilitate the implementation of the GEB strategies for a subject existing building, it is advised that the following conditions should be satisfied: - The existing building should be of age approaching 40 years of age and maintenance is observed to be carried out, like water seepage/plastering works are fading out.
- The building is recommended to form an Owners’ Corporation Committee (OCC) under section 3.3A of the Building Management Ordinance (Cap 344) of HK Government. It would help to made decision much easier as the power and obligations of this OCC are recognized by the HK Government.
- Maintenance and green improvement should be carried out in one go as HK Government has grant and loans provided for maintenance under the Building and Maintenance Scheme (BMMS) in January 2005.
The GEB Strategies involves the following procedure as outlined in the fig 5.1. - Pre GEB Survey
Once it is ascertained that the subject existing building need major renovation/maintenance, the OCC should carry out a study to: - Establish the scope and area of the maintenance and green to be carried out
- Identify if Government loan and grant is available or eligible for this type of maintenance/green area
If all goes positive, a green professional, Green Pro (like Beam Pro) recognized by HK Government can be recruited to carry out the Green Audit Award assessment. - GAA assessment
The green rating assessment can be carried out under the above proposed GAA. Once it is certified in the negative. A green improvement plan can then be developed. - Green Improvement Plan
The green deficiencies/potentials identified under the GAA can be grouped under each performance category and a green improvement plan can be established to carry out the green improvement together with the maintenance works. - Green measures implementation
Once the green improvement plan is decided to carry out, the OCC should go through the cost benefit and risk checkup considering the Government grant/ loan to be granted together with the green technologies to be adopted. Reference can be made to the most cost effective and efficient green technologies that have been identified under this study. - Post GAA assessment
A post green assessment should be carried out after the green/maintenance improvement to see if the green standard can be achieved. Further green improvement works should be done until the green award is ascertained/verified. - Regular monitor and review
It is important that a constant/frequent monitoring of the existing building energy savings performance data should be carried out after the post GEB period to see if energy savings/the occupants health and comfort are continuously maintained. A maintenance / management policy should be incorporated with all the green measures adopted for continued monitoring of the effectiveness of the green implementation. - Pilot Test of GAA- A Case Study
A Hong Kong public housing estate of 11 blocks, Wan Tsui Estate (WTE) in Chai Wan, Hong Kong was chosen for the illustration of application of the GEB strategies/technologies and the green building rating under the Green Audit Award (GAA) plan adopted. The reasons behind why the public housing were selected for the pilot test were of twofold: - About 2.3 million out of 7million people are residing in public rental housing built by Hong Kong Housing Authority (HA). HA has an existing public rental flats amounting to 0.7million stocks (Liu, et al, 2013). There are 205 Estates with 58 Estates that are over 30 years.
- GEB is one of the key maintenance strategies promoted by the Housing Authority of HK for the public housing. To upkeep the provisions and facilities of an old estate so that it can continue to provide tenants with a quality living environment meeting their up-to-date needs, an Estate Improvement Program (EIP) has been formulated for estate of about 40 years old after detailed structural appraisal under the Comprehensive Structural Investigation Program (CSIP) and confirmed as structurally sound and economically viable for maintenance.
Fig 6.1 shows for the location plan of Wan Tsui Estate (WTE) a public estate of Chai Wan Estate adjacent to Chai Wan MTR Station Fig 6.1-Location plan of Wan Chui Estate (WTE) in Chai Wan, Hong Kong As illustrated in the Table 6.1, WTE was completed in 1979-2001 with a site area of 55,000m2 at Chai Wan District. With its unique characteristics built in adjacent to the Cape Collinson Crematorium in Chai Wan, it consists of four slab block buildings of 17 to 18-storey high, two car park of one storey and a shopping center. It is a mature estate with a total number of 3,600 flats. Amongst the population of 10,600, 30% (3,200 persons) are elderly tenants, 60% of the households have elderly member aged 60 or above and about 60 flats are occupied with members of physically disabilities. The six houses about 40 years under this study is laid down in the following Fig 6.2 Wan Tsui Estate (WTE) with layout plan showing the six houses with age about 40 years under this case study | SUSTAINABLE SITE [SS-10] | Site set up –reserve existing natural state | Carpark facility provided for the tenants.

RP Credit - The Improvement Plan and GAA Re-assessed award
Based on the green deficiencies/potentials identified under the above GAA assessment, the green improvement plan as indicated in the table 6.3 can be put forward pursuant to this particular existing building [WTE]. The GAA reassessment is put forward in the Fig 6.4 and Fig 6.5. The total points awarded to WTE after incorporating the improvement plan will be 48 falling within the minimum tally of 40 to ≤ 50 point and the WTE under test after the improvement plan will be certified under this GAA re-assessment Table 6.3 the Proposed Green Improvement Plan for WTE Fig 6.4 The GAA re-assessment points awarded to WTE: LT-13; SS-4; WE-4; EA-8;MR-5; IEQ-10; EV-1; HI-2; IN-0; RP-1 [∑48] The detailed improvement in awake of the assessment under the GAA plan can be evaluated and put forward under each performance below: - LOCATION AND TRANSPORTATION [LT]
- As the estate is located quite near to the public transport, most of the building tenants are using the public transport like buses and MTR.
- The connectivity of each block and the adjacent shopping malls are considered adequate but lift tower should be provided to facilitate the aged group of the estate that is growing. See Fig LTR1
Fig LTR1 - Lift Tower is proposed to relieve the aged group to access the footbridge connected to the adjacent shopping malls Lift tower proposed to relieve the aged group connected to adjacent shopping malls - SUSTAINABLE SITES [SS]
- Ecological integrity can be preserved by providing green roof at the shopping centre located at the centre of the estate. It not only provides aesthetics enhancement to the neighborhood, it also roof slab temperature by about 4℃, and increases the overall green ratio to 28% of the total Construction Floor Area of the estate. Vertical greening is also provided for low rise structures, such as refuse/pump rooms. See Fig SSR1.
Fig SSR1-Provision of green roof to the top roof of the shopping centre and vertical greening to the refuse/pump room. Vertical green wall to pump room - Landscaping: the existing landscape of WTE can be upgraded by soft landscaping under the Landscape Improvement Program with local gardens. See Fig SSR2
Fig SSR2 Set up local gardens to stimulate the occupants’ involvement in greening the surrounding environment of WTE - Rain Water Harvesting: WTE shopping centre. Both rain water and condensate from the shopping centre's A/C system is harvested for irrigation. 65% annual reduction in water consumption for irrigation. See Fig SSR3.
Fig SSR3 The rain water harvesting scheme Pipe works for collection of rain water Pipe works for irrigation system Fig WER1 Cooling tower water use: reclaimed water for irrigation of soft landscape area - Energy Recording Appliances
WTE can install energy recording appliances to support energy management and identify opportunities for additional energy savings by tracking building level energy use and continue to make use of the Housing Channel at the ground floor lift lobbies of public rental housing blocks to disseminate green messages to tenants and encourage them to lead a green life. See Fig EAR2 - MATERIAL AND RESOURCES [MR]
- Use of timber from sustainable source from Forest Stewardship Council (FSC) certified. See Fig MRR1
Fig MRR1 Timber use from sustainable source from Forest Stewardship Council (FSC) - Change the refuse storage to material recovery room. See Fig MRR2
Fig MRR2 Change of the refuse storage to material recovery room - Provide mail box type disposal system for recycling materials. This will encourages source separation of domestic waste and provide protection and avoid nuisance. See Fig MRR3
Fig MRR3 Change to mail box type waste disposal system 6. INDOOR ENVIRONMENTAL QUALITY [IEQ] - Green cleaning equipment: Refuse Handling System: WTE can adopt a designated refuse area to facilitate the cleaning and avoidance of pest and odors. See Fig IEQR1
Fig IEQR1 The refuse handling system - Integrated pest management :
Installation of De-odorizes at the Covered Refuse Collection Points Since 2003, new de-odorizers are installed at covered refuse collection points in newly-completed estates, where bio-chemical technology is employed to contain the odor as serves as a pest control management. See Fig IEQR2. Fig IEQR2 De-odorizes at the Covered Refuse Collection Points - Occupation comfort survey
WTE can conduct periodically on-site measurement to verify the effectiveness of air ventilation technology and generate data for benchmarking improvement opportunities. See Fig IEQR3. Fig IEQR3 Checking ventilation device - Economic Value [EV]
- WTE can use energy saving lighting installation that can save 10% energy consumption
- WTE can hold “Earth Hour” campaign by switching off the non-essential external lightings in public rental housing estates to show support for energy saving.
- WTE can take measures to demand control to generate and dissipate energy efficiently i.e. periodic comparisons on various consumption performances of the blocks within the same period in previous year, and periodic comparisons of various energy use indexes of individual block with the average figures of all Public rental Housing blocks in Hong Kong. See Fig EVR1
Fig EVR1 The energy consumption data 4-month average water consumption of landlord at public area (m3/flat/4-month) | Bi-monthly electricity saving performance of tenants - Human Impacts [HI]
- WTE can implements the Source Separation of Domestic Waste Programme so as to enhance recycle of waste. See Fig HIR1.
Fig HIR1 Domestic waste separation programme - To promote outdoor activities so as to use less lighting. WTE can introduce skylight construction, open space design to allow more sunshine and daylight. See Fig HIR2
Fig HIR2 Provision of daylight into the stalls And add lift tower to shopping centres for those disadvantaged groups. See fig HIR3. Fig HIR3 The tower lift for the inferior/aged groups - INNOVATION [IN]
- Twin Tank System: The objective of the twin tank system is to provide uninterrupted water supply to tenants, even during cleansing of water tank. While recognizing the social and environmental benefits, the economic implication has also been taken into account. The twin tank system in WTE utilizes the existing two water tanks located on the same roof with modification of pipe-works. Such arrangement is more cost-effective as it retains the existing structure to avoid demolition and construction waste, but at the same time improve the quality of living and sustainability of the estate. Twin Tank can be provided to Old Slab –Shing Tsui, Mei Tsui, Wai Tsui and Chak Tsui and Double H blocks-Fook Tsui and Yee Tsui with modification of pipe works connecting the two tanks together. See Fig INR1

- Sound Barrier Balcony: Using noise barrier and absorption materials which can lower the sound decibels to almost 8dB (A). See INR2
Fig INR2 The Sound Barrier Balcony with section drawings Sound Barrier balcony with sloped glass panes to bar the sound absorption. - Acoustic Window
HK Housing Authority has designed a type of acoustic window which functions as a window with double glazing with openings offset to allow the natural air flow. Subsequent to conducting laboratory tests on this window design concept which gave very promising results, full scale mock-up flats installed with prototype acoustic window was set up on site for in-situ acoustic measurements. Upon testing for different flat and window scenarios, it was established that the acoustic window could achieve noise attenuation up to 8 dB(A). See Fig INR3. Fig INR3 The acoustic window with diagrammatic drawings The improvement measures are grouped into five categories: i) data and records gathering (e.g. environmental purchasing records, waste records, etc.), ii) procedures/manuals/guidelines development (e.g. tenant guidelines), iii) site measurements (e.g. water quality survey), iv) technical studies (e.g. waste audit, energy audit, carbon audit and water audit) and v) building improvement works (e.g. modification of existing refuse storage areas with independent mechanical air filtration system, replacement of water cistern and urinal flush valve from single flush to dual flush system, sensory water taps for public toilets and implementation of ISO 50001 Energy Management System.) 10. REGIONAL PRIORITY [RP] - WTE should add incentives that address regional feature to enhance health and comfort of the occupants. As 30% of the population belongs to the aged group, wherein 60% households have elderly members aged 60 or above and 60 flats are occupied with members of physically disabilities, more provisions like disable toilets, travelling ramps, tower lifts and leisure/ recreation area for elderly persons with fitness equipment for senior adults should be provided.
- Barrier free access [BFA] and connectivity: WTE was completed in 1979-2001 with a site area of 55,000m2 at Chai Wan District. With its unique characteristics built in adjacent to the Cape Collinson Crematorium in Chai Wan, it consists of four slab block buildings of 17 to 18-storey high, two car park of one storey and a shopping center. It is a mature estate with a total number of 3,600 flats. Amongst the population of 10,600, 30% (3,200 persons) are elderly tenants, 60% of the households have elderly member aged 60 or above and about 60 flats are occupied with members of physically disabilities.
To address the ageing problem, particular attention should be paid to the special needs of the elderly and disabled tenants, their living pattern and their integration with the younger generation. There is one important consideration in designing the improvement works for an old estate such as WTE, i.e. many tenants have grown up and grown old with the estate and have spent their lifetime in the estate. Around 30% of the population in WTE aged 60 or above and the percentage is growing. The needs of providing barrier-free access (BFA) and improving connectivity within the estate becomes inevitable. Addition of lift towers should be built for pedestrian cross with no lift provision previously. The new lift towers will made significant improvement of BFA as well as the connectivity of the estate, and should be welcomed by the tenants. Other BFA improvement works, such as the tactile guide-paths, railings at staircases, ramps, accessible parking space, unisex toilets, etc. at communal areas should also be taken due consideration of the valuable feedbacks from Persons with a Disability on BFA facilities. More weather-protected pedestrian walkway network should be provided by extension of the existing covers along the elevated walkways between each block. This weather-protected walkway network enhances the connectivity amongst building blocks and major facilities of the estate. See Fig RPR1, Fig RPR2 and Fig RPR3. Fig RPR3 Proposed Extension of covered walkway - Local Garden Programme
Local gardens at WTE can be set up to promote occupiers ’involvement in greening activities. This should be most welcome for the estate with high % of aged group. Planting day and greening activities can also be organized. See Fig RPR4. Fig RPR4 The Local Garden Programme - Waste reduction campaign can be set up to engender the waste reduction concept and habits in the Estate. See Fig RPR5 and Fig RPR6.
- Results and Discussion
It is commonly aware scientifically that the Earth has experienced an average rise in temperature of 0.6°C over the past 100 years. This climatic change is related to global warming which primarily is due to the burning of natural resource of fuels, land clearance and renovations, over use of heating, ventilation and air condition and lighting. One of the measures to reduce this warming effect is to reduce the energy use globally. Whilst new building works add a small % annually (Power,2008), the remaining large % of building blocks in existence consumes about 26% of the total energy (Eurostat, 2009), in fact around 20-40% in modern countries (The Energy Conservation Center, 2008). As illustrated in the above case study, the Green Audit Award [GAA] methodology is in fact not another green rating technique but it serves as a means/tool to assess the existing buildings aiming to identify their green deficiencies s/potentials so that a green improvement plan can be set up to improve the energy use of these existing buildings which have consumed about 37% of the accumulated energy use in modern countries like US(U.S. Green Building Council, 2007). The GAA integrates two strategic elements, green and environment. This synergy strengthens the role of the classic green rating audit by providing a method that not only optimize the green performance of existing buildings but also achieve a green retrofit of existing buildings, postulate improvement measures and thus making the existing buildings, and so future cities, more sustainable and green. The green improvement plan ensues from the GAA assessment defines the green strategies and the actions that result in measures that have taken into account of the human impact/ value added strategy/other resources limitation peculiar to the subject existing building as identified in the GAA plan. However, prior to the implementation of the green improvement plan, the assessor should consult with the tenants/users of the subject existing building that the following objectives have been clarified (Giuliano Dall’O’, et al, 2012). - Is the GAA aims to reduce the cost of the energy management? If yes, more options can be put forward for the green improvement.
- What is the budget for the green improvement plan and the time for the investment return?This will limit the scope and size of the green improvement plan.
- Will the maintenance of the buildings and the green improvement plan be taken concurrently? If so, Government grants/loans can be sought under the Building Maintenance Scheme currently run in HKSAR.
Once the subject existing building has improved its green performance, it is important to initiate a management/maintenance policy for its maintenance or continued improvement of such services. All the green measures identified and implemented, will become important elements of a management/maintenance policy to continuously improving the green/sustainability of the subject existing building in times to go. Reference can be made to the standard ISO “Energy management systems—Requirements with guidance for use.” to make up the management policy. The standard allows the organization to adopt the systematic approach to continuously maintaining and improving its green/energy efficiency performance. The GAA is thus a useful tool to assess its existing building’s green/energy efficiency (or deficiencies) performance so that the building management can identify very easily the pragmatic approach to adopt a green improvement plan that suits the management resources’ constraints. With the effort of each existing building in adopting the above GEB strategies, an enormous effect will be anticipated in combating the global warming in return. - GAA vs the local classic green audit for existing buildings
The paper cannot be completed without a comparison with the local classic green audit system viz : the HK BEAM plus v1.2 for buildings in existence. BEAM plus v1.2 is the green rating system used for the existing buildings in Hong Kong. Up to now, almost 300 projects are recognized by BEAM plus (www.beamsociety. org.hk/). The two systems are compared in the following area; - The ranking and scoring system
Table 7.1A The Ranking and Scoring Systems (www. beamsociety.org.hk) GAA for Existing Buildings | BEAM plus v 1.2 for existing buildings - The categories and weightings
Table 7.1B The Categories and Weightings GAA for Existing Buildings | BEAM plus v 1.2 for existing buildings Table 7.1A gives each credit rating for the medal assigned. No bronze medal is awarded in GAA. A more detailed weightings are cross compared with GAA vs BEAM plus v1.2 in Table 7.1B. No local transportation, economic value, human impacts and regional priority are found in weightings for BEAM plus v1.2. These differences can be explained as BEAM plus v1.2 is focused on design perspective whilst GAA is more orientated to each existing building situation. Local transportation, economic value, human impacts and regional priority is crucial particularly in Hong Kong with congested and heavy traffic condition to evaluate the actual thermal, visual and audio comfort together with the internal air quality of the existing building. The two systems quantify differently for each category of sustainable performance but basically the two credits are more or less the same. Both systems place a heavy score on energy use: 39 for BEAM plus v1.2 and 30 for GAA. Thus the total score for the two systems are almost the same, 106 for BEAM plus v1.2 and 110 for GAA. However, as stated before, GAA covers more environmental performance on the actual existing building situation than BEAM plus v1.2. With more and more buildings certified under GAA for existing buildings, more environmental performance data can be collated to make the GAA more objective and favors by most of the occupiers/owners of the buildings in existence. It should be pointed out that there is no award system for existing buildings and BEAM Plus v1.2 for existing buildings is normally used as a basis for design renovations for buildings in existence. However, since Aril 1 2011, BEAM plus is one of the requirements to have extra Gross Floor Area (GFA) granted in new projects. This GFA extra area incentive is not applicable for green improvement plans in existing buildings.GAA is put forward as the tool to assess the existing buildings whereby improvement plans with economic value and human impacts can be assessed on the basis of the award so that the tenants can be optioned to carry out the greening measures. Since 1 April 2011, the “Integrated Building Maintenance Assistance Scheme” (IBMAS) is another building renovations service managed both by the HK Housing Society (HKHS) and the Urban Renewal Authority (URA). It will help all the qualified property owners of private residential buildings. The same can be provided for those owners/occupiers to launch green improvement plans. Judgement for the grants/financial assistance can be based on the GAA assessment result as postulated in this paper. The energy savings can be evaluated after implementation of the improvement plans ensued from the GAA assessment. This will form the basis for the Government subsidies. Government may have concern in choosing which existing building should be subsidized in priority. A simple scoring system is proposed with pointers to measure each of the existing buildings with similar functions prior applying for the subsidy. In additional to the data merited under the GAA plan, three indicators will be measured: (1) Energy Efficiency (2) Indoor Environmental Quality and (3) Water Efficiency The measuring instruments are: - Power use data report for the Energy Efficiency
- Occupant survey for the Indoor Environmental Quality and
- Water Meter result for the Water Efficiency
The above measures have been used in various cases as the acceptable tools for the above measurement (Alajmi, 2012; Building Use Studies, 2011; Frontczak, et al., 2012; Oladiran, 2013). The measurements are listed below: - Energy Efficiency
Energy use has to be figured out with the size of the building. Calculating the energy use over size of the building in existence is called building energy pointer (BEP) (Bishop, 2012; GreenTech Malaysia & SEDA, 2013; Moghimi et al., 2011). BEP can be obtained by dividing the total building energy consumed in a year (kWh/year) over its total floor area (m2). - Indoor Environmental Quality [IEQ]
The building occupants’ survey on this IEQ will be used to measure the indoor air quality together with the users’ thermal/visual/acoustic comfort/ satisfaction. Although there are available a number of equipment to measure these set of pointers of humidity/glaring/ heat, etc as in the studies (Baird & Penwell, 2012; Zuo & Zhao, 2014),seeking users’ perception using occupants’ survey of these pointers are more indicative of the actual feeling of comfort in reality. - Water Efficiency
Similar to the power and energy logger, water use is recorded by adapting the number logger to the measured appliance. This allows monitoring of actual water use over the time (say in month) measured as m³ per month. Illustration of the above scoring system to prioritize the subsidy application for a group of existing buildings is illustrated in the Table 7.2. Table 7.2 Illustration of tallying the score for a group of two existing buildings (The numbers put in are for illustration only) As indicated, existing building A has better rank position of 8 compared to existing building B of 10. This means that existing building A should be proceeded with the green improvement first before the existing building B since it may need a lot of retrofits to turn this building B to green. Government subsidy should be granted to existing building A in priority. Similar scoring evaluation can be applied to any number of buildings under evaluation. - GREEN Pro
Like the BEAM Professionals (BEAM Pro) recognized by the HK Green Building Council (HKGBC) for the complete building life cycle, particularly in the building planning and design stage, a GREEN Pro can also be recognized by HKGBC in the same manner for the buildings in existence under GAA. This not only will raise/motivate the green awareness of the existing building owners/tenants but will also assure them that the GAA assessment is recognized by the Government. With the support by the Government and HKGBC, the adoption of GAA to promote the green transformation of the existing buildings can be realized. This will help turning the city green ultimately. - Economic Incentives
The Hong Kong Department for environmental protection (HKEPD) has appointed the Chinese University (CU) in 1996/97 and the Hong Kong University (HKU) in 1997/98 to study the correlation of the air contamination and morbidity (illness) and mortality (death) of the health of the public using the data available. (www.legco.hk). The above studies discovered that high connections between the amount of air contaminants [ie. nitrogen dioxide (NO2), sulphur dioxide (SO2), respirable suspended particulates (RSP) and ozone (O3)] and those admitted to hospital and death rate for respiratory and cardiovascular diseases. (www.legco.hk).The cost-of-illness (COI) approach has been used to derive the immediate cost of going to hospital and those received medical treatment at the clinic, and implied cost of loss of daily works salaries. (www.legco.hk) A selected people survey was used to measure the each person's willingness-to-pay (WTP) to avoid being admitted to hospitals and risk to die.(HKEPD, April 1998) (www.legco.hk).The economic costs due to air pollution to health were compared to Gross Domestic Product (GDP). (Census and Statistics Department, 1997)(sc.info.gov.hk). In 1996, the HK GDP was 1,108.6 billion. A relatively higher GDP percentage can be resulted as indicated in the table 7.3A: Table 7.3A COI and WTP estimate expressed as % of GDP in 1996 Table 7.3B COI and WTP estimate in 2016 using the same % of GDP in 1996 *GDP in 2016 = 2,489.1billion Table 7.3CAge of Buildings by Type in 2016 (Building Department) Table 7.3D Estimate of total number of buildings in 2018 with age ≥ 40 years This 26,000 number of existing buildings will share the budget of HK$10 billion subsidy/loan with each building getting around HK$ 400,000. This budget expenditure of HK$10 billion (10B) and its share of HK$ 0.4 million per building ≥ 40 years is considered justifiable in comparison of the high economic costs of COI and WTP (8.7B+12.7B) amounting to 21.4 billion as estimated in 2016. - Conclusions/Contributions
This paper presents a systematic buildup of GEB strategies to enhance the green/ sustainable standard of the buildings in existence, the energy use of which consumes around 30% in average of total energy use in modern countries. In making the GEB strategies feasible, a GAA plan is developed to assess the existing building condition to determine its green deficiencies so that a green improvement plan can be worked out for the retrofit works. An overview of the previous GEB studies have illustrated that green/sustainable performance of the buildings in existence can be improved significantly using the most acceptable green technologies particularly the energy efficient lighting fixtures with energy savings up to as much as 65%. A management/maintenance policy is proposed to maintain the green improved condition. The green measures once adopted will become the core elements of a management/maintenance policy for the property management company to sustain these green improvement technologies. It should be reiterated that the case study above pointed out that a considerable green improvement in Hong Kong congested environment rested largely in the improvement of the internal environment quality [IEQ] of the building in existence in the context of thermal, visual, acoustic and indoor air quality. This may be one of the major green potential to be adopted in making Hong Kong city green and sustainable. This GAA assessment as one of the key GEB strategies to open up the green potential of an existing building is considered as the most cost effective, if not the best solution to promote green/ sustainable performance of the buildings in existence. However, without the Government support and promotion for this GEB strategy using GAA as the assessment tool, the long term continued green awareness and implementation may not be sustainable. To integrate the GEB strategy with the current maintenance scheme administered by the Urban Renewal Authority [URA], both technical and financial assistance from URA can be assured to maintain and sustain these GEB strategies. The significant improvement of the Interior Environmental Quality as testified in the above case study together with the measurable economic cost savings of air pollution in terms of Cost of Illness and Willing to Pay as identified by a joint study of Chinese University of HK and the HK University from 1996-1998, the substantial expenditure of a budget of HK$10 billion in the coming year of 2018 is highly justifiable for the Government to implement this hybrid of GEB and Maintenance scheme to promote the GEB strategies in Hong Kong. The budget granted can be prioritized under a simple scoring system pursuant to green improvement report postulated by a qualified Green-Pro recognized by the HK Government. Carbon neutral and zero emission buildings are the crux of the GEB’s aim and objective, which can be named as the “next generation” green/sustainable building. (Boake, T. 2008)(ijfm.net).In times to come, GAA compliant existing buildings will become the common practice for all the participants in the property and the construction sector of the industry. It is confident to believe that GEB strategies with its GAA plan will advocate the green promotion of green cities in the world.
Literature Review
1. Key elements influencing GEB The success of a GEB program depends on many factors. Fig. 3.1 shows the key factors that have grave impacts on GEB, including the occupants’ behavior, the GEB methods of applications, Government’s support, property owners’ intent, the building’s design criteria, and other factors. (Ma, et al, 2012) Fig 3.1 Key elements influencing GEB (Ma, et al, 2012)
Major Results
| A reduction of total energy use ranging from 40% ~ 60% in the North climatic zones | Using exterior envelope insulation with insulated glass unit and effective HVAC system, the energy savings ranging from 36% to 60% for thermally better performing glazing renewal. |
3.4.3 Other Types of Buildings The campus of Melbourne University, Australia (Stefano, 2000) It was found that the lighting fixtures at Melbourne University of Australia attributed almost 30% of the electricity being used. Thus amendment of the existing fluorescent fixtures to four different energy efficient lighting fixtures has significantly reduced the electricity bill. The following replacement of four alternatives lighting fixtures has resulted in energy savings of 1. 13.9% for using electronic ballasts; 2. 20.5% for T8 magnetic ballasts; 3. 24.4% for T8 electronic ballasts; and 4. 64.9% for T5 electronic ballasts The energy savings comparison is drawn up below in the table 3.3. Table 3.3 - The energy savings using four different energy efficient lighting fixture for the mentioned Australian University Major GEB Technologies used | Replace 1200mm fluorescent lighting appliances with the following four different energy savings appliances : - Electronic ballasts,
- T8 magnetic ballasts,

1.The Identification of the Top Five GEB Technologies The above GEB studies indicated a significant improvement of energy savings of the buildings in existence if the GEB technologies are carefully selected and implemented properly.
This includes:
- annual energy usage/distribution; and
- renewable energy supply mechanism used.
4.Material & Resources [MR] Material & Resources features include the materials in their: - assortment and usage; and
- disposal and reuse
5.Indoor Environmental Quality [IEQ]
This covers:
- air movement and its convection ; and
- thermal, visual and audio comfort of the indoor condition;
It should be pointed out that a significant improvement can normally be done to upgrade the IEQ with least cost and effort for existing building. As it can be seen in the pilot test in terms of a case study in this paper, IEQ can be greatly improved for existing building with ease.
8.Innovation [IN]
Credits will be given to those performance with significant, measureable environmental performance using an innovative strategy/technology. Innovation includes: - Added value to the environment ;
- New method to renew energy and reuse of water discharge;
- Alternative internal transportation with ease and under cover; and
- Substantial reduction of noise and air pollution to the living community.
9.Regional Priority [RP] Credits will be awarded to each performance feature specific and unique to the region of the buildings in existence under study The GAA credits allocation The GAA weighting and allocation of credits and its individual assessment were expressed under a global trend as dawn up in fig 4.1.

As 30% of the population belongs to the aged group, wherein 60% households have elderly members aged 60 or above and 60 flats are occupied with members of physically disabilities, more provisions like disable toilets, travelling ramps, tower lifts and leisure/ recreation area for elderly persons with fitness equipment for senior adults should be provided.
- Improve Barrier free access [BFA] and connectivity: WTE is a mature estate with a total number of 3,600 flats. Amongst the population of 10,600, 30% (3,200 persons) are elderly tenants, 60% of the households have elderly member aged 60 or above and about 60 flats are occupied with members of physically disabilities. Addition of lift towers will made significant improvement of BFA as well as the connectivity of the estate, and should be welcomed by the tenants.
- Add other BFA improvement works, such as the tactile guide-paths, railings at staircases, ramps, accessible parking space, unisex toilets, etc. at communal areas can also be considered and provided.
- Provide more weather-protected pedestrian walkway network by extending the existing covers along the elevated walkways between each block. This weather-protected walkway network enhances the connectivity amongst building blocks and major facilities of the estate.
- Set up local gardens at WTE to promote occupants’ involvement in greening activities. This should be most welcome for the estate with high % of aged group. Planting Day and greening activities can also be organized
- Set up waste reduction campaign to engender the waste reduction concept and habits in the Estate.

To make the target of HKSAR reduce to energy power of 40% by 2025 and carbon concentration by 50-60 % by 2020 using base year of 2005, the green improvement plan generated by GAA for existing buildings will be a great help and can offer the most cost effective way to achieve the target as the buildings in HK consume the city electricity of almost 90%. As indicated in the findings from the GEB studies for office, residential and other types of buildings (Dascalaki, et al, 2002) (Verbeeck, et al, 2005) (Stefano, 2000), there concludes that using the GEB strategies can achieve a total of energy savings in a range of 40%-60%. This high energy savings will definitely be a good contribution to carbon intensity reduction in the range of 20%-30%. Like Beam Plus which will grant Gross Floor Area (GFA) concessions capping at 10 % of the total GFA of the development projects by HKSAR since 1 April 2011 using Beam plus as a design basis, Government should take a similar lead in promoting GAA for existing buildings assessment. The Building Management and Maintenance Scheme (BMMS) in January 2005 implemented by the Housing Society is a good example offering financial assistance with a funding of HK$1 Billion in its first launch to implement the grant scheme for aged owners.

The above study showed that a rather high economic cost will be effected to health due to air pollution.(www.lego.hk) This will enable the government to develop a more cost effective air pollution combating scheme as well as the subsidy scheme to promote internal air quality. As indicated in the pilot test of GAA, there is a significant improvement of internal environmental quality (IEQ) after adopting the green improvement plan postulated by the GAA assessment. The IEQ has improved significantly from 3 points to 10 points as shown in the fig 6.3. It is proposed that a go-green scheme can be hybridized with the “Integrated Building Maintenance Assistance Scheme” (IBMAS) as the “Integrated Greening Existing Building Maintenance Assistance Scheme (IGEBMAS)”. The Government can earmark a Budget of HK$10 billion (say at 0.4% of GDP from the above COI and WTP studies) in the coming year of 2018 to launch the IGEBMAS and the Urban Renewal Authority (URA) can be appointed to administer the IGEBMAS. URA, an independent not-for-profit organization, will provide technical and financial assistance/subsidy/interest free loan to qualified private property owners with GAA certified and green improvement plan certified by the Green Pro together with the maintenance plan. URA, will also facilitate IGEBMAS, and approve applications and release the subsidy to qualified property owners. Priority will be awarded to those existing buildings getting the higher ranking marks using the above proposed Simple Scoring System. The significant improvement in the IEQ using the green improvement plan as illustrated in the above pilot test case study will have a great economic cost reduction based on the COI and WTP estimate in 2016. This again justifies the budget of HK$10 billion to be adopted in the coming year of 2018 to promote IGEBMAS in Hong Kong. Further justification of this budget can be evaluated of the number of existing buildings that will be benefited as result of this GEB strategy. The number of buildings that call for urgent maintenance and green improvement will be proposed for those buildings ≥ 40 years which can be estimated as follows in the table 7.3CAge of Buildings by Type in 2016 (Building Department) and table 7.3D: the estimate of total number of buildings in 2018 with age ≥ 40 years.

I am very pleased to serve as EBM of the journal, I hope many years of my experience in stem cells can help the journal from one way or another. As we know, stem cells hold great potential for regenerative medicine, which are mostly used to promote the repair response of diseased, dysfunctional or injured tissue using stem cells or their derivatives. I think Stem Cell Research and Therapeutics International is a great platform to publish and share the understanding towards the biology and translational or clinical application of stem cells.
