Thailand’s Building Energy Code (BEC) was introduced in March 2021 and only applied for new buildings with a gross floor area greater than 10,000 sqm. This threshold was now lowered to 5,000 sqm. to include more buildings and will be even more tightened in March 2023 (2,000 sqm.).

The BEC must be applied on the following building types:

Group 1:       Office, Education
Group 2:       Theatre, Convention Hall, Entertainment, Department Store
Group 3:       Hotel, Hospital, Condominium

The BEC sets minimum requirements regarding the thermal performance of the building façade (OTTV), roof (RTTV), lighting (LPD), air conditioning (AC) and renewable energies (RE). To allow more flexibility regarding the building design it is also possible to follow a whole building approach where the weakness of one system can be compensated by the strength of another system.

EGS-plan (Bangkok) Co., Ltd. has many years of experience with BEC calculations since staff members have been involved in the update of the BEC and already conducted BEC calculations for several projects.

The new administrative building of Nong Fab LNG receiving terminal was awarded TREES NC V1.1 Platinum! The office building is located in Rayong and has a gross floor area of approximately 8,647 m² on 3 stories and a basement.

EGS-plan supported the green building certification according to TREES with our engineering services for fundamental commissioning. The certification consultant of the project was our partner company Africvs Co., Ltd.

Building commissioning is a quality management process, which verifies, that the technical systems and the building envelope of a new building are meeting the owner’s project requirements. Commissioning procedures were managed and overlooked by EGS-plan and began during the pre-design or planning phase of the project, continued through the design and construction phases, initial occupancy phase, training of operations and maintenance (O&M) staff, and into occupancy (for warranty and future re-commissioning).

The result is a building which works as intended with a low energy consumption, great thermal comfort, and low maintenance costs.
