3 1- GB definition 3

4 1. GB definition Global Building Impacts 17% of fresh water consumption 25% of wood harvest 33% of CO2 emissions 30-40% of energy used 40-50% of raw materials used Source: Capital E

5 1. GB definition What is a green building? Environmentally responsible and resource-efficient throughout their life-cycle. Designed, constructed and operated to reduce the overall impact on human health and the natural environment by: Efficiently using energy, water, and other resources Reducing waste, pollution and environmental degradation Protecting occupant health and improving employee productivity

6 1. GB definition Green Building benefits and savings GHG Emission reduction potential 30% ENERGY 35% CARBON 30-50% WATER USE 50-90% WASTE COST Healthier working/living place Higher productivity Occupant Brand Value Lower operating costs Increased selling and renting value Source WorldGBC

7 2- GB rating tools VS regulation 7

8 2- GB rating tools VS regulation How Green is my Building?

9 2. GB rating tools VS regulation Building performance classification Environmental performance Sustainable Building (Zero Energy Positive Energy) Green Building (Certified against a Rating Scheme) Resource Efficient Building (EDGE IFC tool) Energy Efficient Building (Building Code Regulation) Business As Usual

10 2. GB rating tools VS regulation What is a Green Building Rating Tool? A framework for: o benchmarking building performance o encouraging integrated building design & construction o raising awareness of GB benefits o meeting legal obligations o attaining resource security o 3 rd party verification of environmental credentials

11 2. GB Rating Tools VS regulation GB rating tools in Asia 11

12 3- GB development triggers and obstacles 12

13 3- GB development triggers and obstacles Main triggers worldwide Main obstacles worldwide Source: World green building trend 2016 (WGBC) Dogde Data & Analytics 13

14 3- GB development triggers and obstacles In Vietnam Industry: Wrong perception of GB cost premium Lack of technical/management skills Scarce green products Highly speculative market Government Insufficient regulation & law enforcement Insufficient guidance & lack of incentives Highly subsidised energy cost Users: Lack of clear demand from end users

15 3- GB development triggers and obstacles What drives green initiatives in Vietnam? MNC corporate guidelines Financial long term benefits of investors/operators Sales and marketing considerations Implementation of more stringent EE and environmental codes Increasing awareness of global environmental issues

16 3- GB development triggers and obstacles GB development in South East Asia A growing interest and substantial development since Mainly through voluntary systems run by non for profit organisations. This global momentum has been coordinated through the World GBC platform. Only in Singapore and China, government has been leading GB development. Recently IFC introduced EDGE, a resources efficiency tool, to address social housing and other lower end construction segments.

19 4- Financial aspects of GB 19

20 Source: Nutecgroup Source: 4- Financial aspects of GB Life Cycle Cost analysis Viewed over a 30 year period: Initial building costs account for approximately just 2% of the total, while operations and maintenance costs equal 6%, and personnel costs equal 92%. O&M costs = 2 X cumulated design and construction costs. This clearly illustrates the importance of planning and running operations at an optimised level. 20

21 4- Financial aspects of GB Design change and cost implications 21

22 4- Financial aspects of GB Financial benefits - Benefits consistent over the globe - Payback periods vary depending on countries - Shorter payback time in developing countries (max 5 years) Source: World green building trend 2016 (WGBC) Dogde Data & Analytics 22

23 4- Financial aspects of GB What added costs? 1. Consultants / specialist costs 25 to 200K USD 2. Certification fees 4.5 to 30K USD 3. Extra documentation 4. Technical choices depending on projects: Extra metering High COP HVAC equipment Improved glazing Efficient lighting Extra ventilation Water saving fixtures Alternative energy Commissioning Etc. 23

26 4- Financial aspects of GB CASE STUDY 1 : VM MOC BAI FACTORY AND OFFICE Location: Moc Bai, Tay Ninh. GFA: 72, m2 Certification targets: Prove sustainability credential to NIKE, Improve work place to reduce churn Certification: Each building achieved LOTUS certified and LEED Silver Challenges: Unresponsive designer and contractor Extra costs: 2% over construction costs: Increased WWTP capacity and standards Improved landscaping design Improved daylight and artificial light Improved ventilation and accessibility Added solar water heater Payback: 2.5 years at today s rate Energy cost savings: USD 118,000 p.a. Water cost savings: USD 47,000 p.a. 26

27 4- Financial aspects of GB CASE STUDY 2 : POUCHEN KINDERGARDEN Location: Binh Duong GFA: 3800m2 Certification targets: Pou Chen sustainability roadmap...the biggest employer in VN Certification: LOTUS Silver Challenges: Poor documentation skills of design team Extra costs: 1.8% over construction costs ($93,100 USD) Added energy and water meters Improved artificial lighting & AC Improved disabled access Water flow reducers Administrative costs Payback: 8.5 years at today s rate (because of very low annual running costs) Energy cost saving: between $6,800 & $7,800 USD/annum Water cost saving: $3,627 per annum 27

28 4- Financial aspects of GB CASE STUDY 3 : EXIMBANK Location: HCMC Certification: LEED GOLD (under going) Challenges: Unreasonable design assumption Extra costs: QS pre-fs cost prediction of 3% - Current estimate 0.5% Rainwater recycling toilets and irrigation (50% of water is recycled) Glazing cost increase of 0-4% CO2 monitors to 4 meeting rooms Chiller sizing saving of 10% Payback: Payback 5-8 years (at today s electricity & water rates) Annual cost saving of $6,800. Energy saving increased from 4% to 34% Projected operational savings of $26,700 annually Predicted water saving of 37% internally and 100% externally 28

29 4- Financial aspects of GB CONCLUSION Building Developers/Owners: Think long term Start as early as possible Set realistic targets Insure appropriate operations management to harness benefits Government: Set EE and environmental legislation, targets and trainings Define and implement incentive policies Develop pilot projects with public buildings Construction industry: Develop EE/ GB design skills Develop financial skills 29
