Keynote lecture
by Mr. Kimura from METI

Mr. Christopher De Guzman Zamora (the representative of ACE) presented the EE&C Latest Policy and Legal Framework in ASEAN. His presentation highlighted the following information.

  • Under the APAEC Phase I:2016-2020 Energy Efficiency and Conservation Program Area, ASEAN has achieved 24.4% energy intensity reduction, based on 2005 levels (exceeded the target of 20% reduction by 2020) .
  • The introduction of the development of APAEC Phase II: 2021-2025 which will focus on promoting energy transition, enhancing resilience and inclusive growth.
  • In the latest AEA in 2019, ASEAN has received two (2) submissions for ZEB Ready subcategory. However, based on the decision of Board of Judges (BOJ) there was no winner under the subcategory. Therefore, this ECAP 20 was designed to also enhance and improve the guideline submission of ZEB Ready subcategory under AEA.

● Thailand has considered the proposed changes in the scoring system of AEA and would like the participants to comment as follow:
i. In considering that the existing rule doesn’t allow the judge to score the reports submitted by his/her own country, it is noted that the proposed ranking system, using ranking average, may cause bias amongst countries.
ii. In addition, it should be noted that the ranking system may not reflect the true quality of each report if number of judges is not enough. This effect is most prominent when each report is of similar level in quality.
iii. To solve this problem, EE&C SSN should study 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.

Mr. Dinh Chinh Loi (Official, Ministry of Construction (MOC)), in his Country Report, explained the following items.
