Scope of BEC Law
BEC Ministerial Regulations : version 2019
• Enforcement of new or retrofitted buildings with using area more than 2,000 m2
in 9 building types (Draft Min Regulations 2019 Will start to force building size of 10,000 m2 in the 1st year
and reduced to the size of 5,000 m2 in the 2nd year and 2,000 m2 in the 3rd year)

To prescribe types and sizes ofbuildings and also standards, rules andprocedures for designing of energy
conservation building.
New or retrofitted buildings being
constructed which have total area of all
stories equal to 2,000 m2
or more must be designed under theenergy conservation requirements

4Implementation of Thailand’s• Revise energy conservation act and set standard for energy consumption onbuilding design plan ( Expect enforced start in 2020)• Training and certified “Energy Conservation Building Auditor”• Educate stakeholders such as Institute, building design engineer & architect• Promote energy efficiency building design (enforced gov-buildings, voluntary
private buildings• Improve database system for encon building construction materials & appliances• Promote BEC Award to public

ASEAN Energy Awards
Thailand has considered the proposed changes in the scoring system and would like to comment
as follow:
1. With the existing rule which doesn’t allow the judge to score reports from his/her own
country, it is noted that the proposed ranking system may cause biases amongst countries, asshown in figure 1.

2. In addition, it should be noted that the ranking system may not reflect the true quality ofeach report. This effect is most prominent when each report is of similar level in quality

9Recommendations

1. It should be voted that both the old and proposed system have their own
limitations. However when enough judges are presented, the old and theproposed system produce similar result. Hence, Thailand would like toencourage all ASEAN countries to actively participate in the AEA judging session
and invite all countries to propose possible ways to promote participation.

2. Thailand would like all members to consider the possibilities of using online
system to encourage participation by all countries. This may ultimately eliminate
the need for physical meeting which helps reduce cost and promotes
participation.
