1. Enforcement of the Ministerial Regulation
• Enforcement BEC standard •Development of BEC auditor
training •Tightening BEC standard
2. Supporting new energy conservation building
• Energy building labels • Financial incentives, for example government funds or low interest personal loans
3. Zero Energy Building
• Study green building design, economic value and the climate change of Thailand
• Zero Energy Building Plan
To support the new projects receive formal green building certification as LEED, TREES.
Target: Government and private new building total area ≥ 2,000 m2
9 types of new buildings total area ≥ 2,000 m2
In 2017, Starting enforce with new buildings area ≥ 10,000 m2
Down to small size in 5 years

Ministerial Regulation 2009 Ministerial Regulation 2017
Old standard Enforcement new or retrofitted buildings of 9 buildings types which have total area ≥ 2,000 m2
New standard Enforcement new or retrofitted buildings of 9 buildings types which have total area ≥ 2,000 m2. Starting enforce with new buildings area ≥ 10,000 m2 and down to small size in 5 years
• Update defining of “retrofitted buildings” • Define all standard (OTTV, RTTV etc.) in Ministry's
Announcement Ministry of Energy, 2017

“Coordinating Center of Energy Conservation Building Design” • To provide information to any government sectors, state enterprises, or project
stakeholders regarding the evaluation procedures of building plans for energy conservation as required by the Ministerial Regulation
• To create collaborative networks between the government and private sectors in order to lay the foundation of energy conservation building design
2010
Evaluation of energy conservation building (2009 – 2015 = 426 building drawing plans)
BEC’s auditor training 1,800 persons (Architect, Engineer and Building Owner etc.)
MOU municipalities and universities (Bangkok, Chiangmai, Pattaya etc.) (KU, TU, CMU, KMITL etc.)
Private network and professional associations (Engineering institute, Siamese Architects) (SCG, SANSIRI, LPN)
Develop of prototypes for standard government conservation building drawing plans
