03:40, 11/07/2024

On December 28, 2017, the Vietnam Ministry of Construction issued Circular 15/2017/TT-BXD promulgating the National Technical Regulation on Energy Efficiency Buildings.

The Lighting power density in energy-consuming buildings in Vietnam is stipulated by Circular 15 through the following table:

Type of Building	Lighting power density (W/m 2 )
Office	11
Hotel	11
Hospital	13
Medical Center, Health Care*	11
Library*	14
Conference*	15
School	12
Commercial, Service	16
Residential	8
Warehouse*	9
Indoor Parking Area	3
NOTES: - (*) Items within the types of buildings under the scope of the Regulations; - LPD is calculated by dividing the total lighting power according to the design by the total usable floor area; - For buildings that include multiple functional uses (mixed-use buildings): LPD is determined according to the lighting power and usable floor area for each type; - For areas or sections with special lighting requirements in educational and medical facilities: LPD is based on the applied design standards; - For residential buildings, instead of applying the LPD regulations in the table, energy-labeled lighting devices must be used according to current regulations.

Details may be found in Circular 15/2017/TT-BXD effective from June 1, 2018.
