1 Practice in Energy Efficiency and Renewable Energy in Commercial Building: Thailand “A Briefing” presented at the APEC New and Renewable Energy Technologies Expert Group Meeting -28 Meeting during January 2007 NEDO Office, Tokyo, JAPAN Peesamai Jenvanitpanjakul Thailand Institute of Scientific and Technological Research (TISTR)

2  Thai Energy Conservation Promotion Act  Energy Efficiency Measures  Practice in EE and RE in Commercial Building: Thailand Presentation Outline

3 Thailand Energy Situation Energy Consumption by Economic Sectors in 2005

4 The Energy Conservation Promotion Act ENCON Act, April 2, 1992  EPPO – policy  DEDE - executing agency ENCON Act classifies:  Designated Building  Designated Factory

5 ENCON Act specifies the scope of conservation measure:  Efficient Lighting System  Efficient Cooling System  Use of appropriate Construction Material  Installation of Operation Control System Designated Building Designated Building: Total installed capacity of 1 MW or more Office Hospital Hotel Educational Building Shop Shopping Center

6 Energy Conservation Measure  Energy Audit and Management Schemes  Energy Standards and Labeling  Building Energy Codes  Building Energy Rating and Labeling  Tax Incentive  Energy Efficiency Loan Funds  Rebates for Installation of Energy-Saving Measure  Consumer Awareness and Behavioral Changes

7  Compulsory Energy Audit Programs for designated facilities  With grants and subsidy for energy audit  No grant and subsidy since 2005  Voluntary Energy Management and Audit Programs for non-designated facilities Energy Audit and Management Scheme

8 Building Energy Codes  OTTVs- Overall Thermal Transmittance Value  Improve performance of the building  Heating/Cooling temperature  Lighting level  Maximum values for heating/cooling/ventilation  RTTVs- Roof Thermal Transfer Value Minimum requirement on OTTVs, RTTVs For Designated Building

9 Current Practice in Energy Efficiency in Commercial Building: Thailand  Value engineering (VE)  Public Participation  Incentive: Thailand Energy Award Low cost/No cost options No subsidy /no requirement for the energy audit since 2005
