Thiết kế giảm năng lượng tiêu thụ trong các tòa nhà văn phòng ven biển Việt Nam

Abstract

Office buildings are considered one among largest energy consumers compared with other categories due to day-time operation of lighting and office supplies. The used energy is critically higher in the air-conditioned buildings where HVAC system is enabled over course of the day and even the year. In major Vietnamese coastal cities blessed with Nature’s mild climate, the majority of local office buildings are of gathered-block typology that fails to consider the favourable aspects of climate condition. At first, this study aims to investigate the influences on indoor comfort and energy consumption of two key factors, i.e. outdoor climate and solar radiation, in major Vietnamese coastal cities based on bio-climatic analysis of 20-year historical meteorological data from 1981 to 2000. Then, the study suggests the optimal architectural design (Strategies of Climate Control) of office buildings in the considered towns to maximize climatic favours for reduction of energy use, particularly ones for HVAC. In this research, case study is the Danang Administrative Center building.
