  1. Green Buildings in Thailand Leading the way for the Green Mark® certification in Thailand and a look at how Schneider Electric is making its own industrial building green Ms. Phatlapha Prettapapop Business Development Leader – Energy Efficiency Schneider Electric Thailand

  2. Agenda • Introduction: Energy dilemma for buildings in Bangkok Energy Efficiency Index (EEI) Energy Saving vs. Green House Gas Emission • Green Buildings through Green Mark® Certification • Case Study: Schneider Electric’s industrial building inBangpoo • Benefits of An Energy Efficiency Program • Energy Efficiency: How to begin?

  3. Energy dilemma for buildings in Bangkok

  4. High levels of energy consumption 135,000 GWh (thousand million units) electricity consumed in Thailand in 2009 Over 30 % is used in Bangkok Source: Energy Policy & Planning Office

  5. 45,000 40,000 35,000 30,000 25,000 20,000 15,000 10,000 5,000 1990 1992 2000 1996 1994 2002 2006 1998 2004 2008 Electricity consumption growth in Bangkok GWh Consumption Growth Per Year Source: Metropolitan Electricity Authority

  6. Electricity user profile in Bangkok 0.85 % of the electricity consumers are using 60 % of the electricity! Who are they? Shopping malls, large office buildings, factory buildings, hotels, government and institution buildings, large residential buildings and condominiums. Source: Metropolitan Electricity Authority

  7. Energy performance benchmarking for buildings • Gauge the potential in energy savings • Energy Efficiency Index (EEI): total energy consumed per unit of gross floor surface • kWh / m2 / year • Comparison by building category: • Hospital, hotel, office, shopping mall, condominium, government buildings, etc. • Use the benchmarking tools to position your building accordingly

  8. Energy performance benchmarking for buildings (Continue) • Establish the efficiency chart of your building: Revenue House, Singapore Source: National University of Singapore

  10. Energy Demand Side Reducing your carbon footprint through energy efficiency Reducing energy consumption in buildings will significantly reduce GHG emissions in Thailand and save a lot of money for the country in energy imports and fuel subsidies. Typical performance benchmark: 225 kWh / m2 / year Good practice benchmark: 170 kWh / m2 / year • =33 kg CO2 / m2 / year saved 25 % energy savings • One solution: Green Buildings!

  11. Green Buildings through Green Mark® Certification

  12. Energy Efficiency Using less energy by providing the same level of productivity and comfort Water Efficiency Managing water usage by reducing waste Environmental Protection Transportation accessibility, green areas Indoor Environmental Quality High-level comfort through temperature, humidity and lighting control What is a green building?

  13. Community Economic Environmental Health & Safety What are the benefits? Reduce the impact of natural resources consumption Enhance occupant comfort and health Improve your bottom line Minimize strain on local infrastructure and improve quality of life

  14. Global trends of green buildings Green Building councils around the world Increasing interest in green buildings in Thailand is pushing for the development of a Green Building Council in the Kingdom

  15. How to make your building green? • Building & Construction Authority of Singapore launched the Green Mark® certification scheme: • Point-based assessment to rate buildings on their environmental impact and performance • Voluntary program for new and existing private developments • Objectives: • Promote awareness and recognition • Identify best practices in development, design, construction, management and maintenance in buildings

  16. Green Mark 5 Assessment Criteria

  17. Basis for Green Mark® Award The certified project must meet minimum total points for the specific rating, and pre-requisite criteria.

  18. Office Buildings - Count index 10 8 6 4 2 0 80-139 140-199 200-259 260-319 320-379 380-439 440-499 500+ Electricity Efficiency Index (kWh / m2 /year) Building Energy Performance for the Green Mark® Certificate Energy Efficiency Index Benchmark (kWh / m2 / year) Source: Green Mark Assessment Criteria for Non-Residential Existing Buildings (v. 2.0)

  19. Green Mark Response • More than 100 buildings have the Green Mark certification • More than 60 of these buildings are residential developments, which contains over 19,000 green homes. • Millennium Residence receives Singapore BCA Green Mark Gold Award (1st in Thailand) • Owner of the building: MR Sukhumvit Co., Ltd. • Harvesting of waste water and rain water to provide irrigation • Carbon Monoxide Monitoring system for the underground parking facilities to operate the fans only when needed

  20. Case Study: Schneider Electric’s industrial building in Bangpoo

  21. Demonstrating significant energy savings in Schneider Electric’s buildings In 2005, Schneider Electric Thailand decided to undertake an energy reduction program in its industrial building in Bangpoo.

  22. Investment: 1.5 MTHB Savings: 2 MTHB / year* Payback: 9 months* First step to success: energy consumption monitoring • The basis of a successful energy efficiency program is to implement an Energy Management System. • PowerLogic® power monitors were installed at node points to survey the electricity consumption. • Real time data logging and reporting was made through a specialized System Management Software. * During the first year of implementation

  23. Investment: 158.5 kTHB Savings: 122.6 kTHB / year Payback: 16 months Air-Conditioning Optimization and Control • Turn on period of the air-conditioning was optimized in the buildings through control boxes with integrated Programmable Logic Controllers. • Over-sized A/C units were replaced as per actual room requirements. • Staff awareness promotion through strategic communication was made.

  24. Investment: 167 kTHB Savings: 57 kTHB / year Payback: 2.9 years Water Pump Control • A Variable Speed Drive (VSD) was installed at the cool water pump for the chiller system.

  25. Investment: 423.5 kTHB Savings: 488.3 kTHB / year Payback: 10 months Cooling System Optimization • Refrigerant in the air-conditioning was replaced from R22 to hydrocarbon which has a higher cooling capacity. • An evaporative pre-cooling media was integrated to the existing condensing unit at the point of entry of the air. • Preventive maintenance was scheduled on the condensing units according to the readings on the power monitoring system.

  26. Electricity Consumption Indicator kWh / head / day 2005 2006 2007 2008 2009 2010 2011 30 25 20 15 10 5 Results: significant energy savings! 25.6 % energy savings since 2006 236 MWh saved every year, the equivalent of 142 tons of CO2

  27. Benefits of an energy efficiency program

  28. Reduce your Energy Bill Electricity Tariff = Demand Charge (baht/kW) + Energy Charge (baht/kWh) + Power Factor Charge + Ft Charge Consumption Shifting loads can help avoid peaks Night Day

  29. Years paybacks* Energy price 0,11 5,0 0,105 4,5 0,1 Cents/KWh Years 0, 095 4,0 0,09 0,085 3,5 0,08 3,0 0,075 0,07 2,5 0,065 0,06 2,0 2000 2001 2002 2003 2004 2005 2006 The rise in energy prices has improved return on investments Based on an actual commercial building. • Project Cost $1M, • Electricity saving 3500MWh • Project cost and energy savings fixed. Payback time has decreased30% over 5 yearsdue to increase in energy prices • Example based on a US commercial building project • DOE -US Average Retail Cost of Electricity 1993 thru 2007

  30. Contribution to Thai society Coal 35 units 33 units 100 units 3 units saved at the power plant 1 unit saved in the building Reduce Thailand’s dependence on fossil fuels
