A study on energy consumption of hotel buildings in Vietnam

Abstract

This paper aims to determine energy use intensity (EUI) and the percentage of end-use energy consumption in hotel buildings in major cities of Vietnam, including Hanoi, Da Nang and Ho Chi Minh City (HCMC). Data from 32 hotels were gathered from the website on energy efficiency promotion of Ministry of Construction. The average EUI in the whole country was 151 kWh/m2.year, and the figures for Hanoi, Da Nang, and HCMC were 184; 71 and 212 kWh/m2.year, respectively. At the same time, the structure of end-use energy consumption was estimated, of which 54% for heating, ventilation and air conditioning (HVAC), 10% for lighting, 19% for plug equipment and 17% for lifts. Keywords: energy consumption; energy use intensity (EUI); end-use energy consumption.
