tailieunhanh - A study on energy consumption of hotel buildings in Vietnam

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. | Journal of Science and Technology in Civil Engineering NUCE 2018. 12 5 109-116 A STUDY ON ENERGY CONSUMPTION OF HOTEL BUILDINGS IN VIETNAM Mac Van Data Tran Ngoc Quanga aFaculty of Environmental Engineering National University of Civil Engineering 55 Giai Phong road Hai Ba Trung district Hanoi Vietnam Article history Received 13 July 2018 Revised 13 August 2018 Accepted 25 August 2018 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 m1 and the figures for Hanoi Da Nang and HCMC were 184 71 and 212kWh 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.

Introduction Hotels are classified as one of the highest energy consumption building categories. According to 1 hotels together with offices and retails were the most energy consumption typically accounting for over 50 of the total energy consumption in UK 64 in US and 85 in Spain. In a study on the energy efficiency of 29 hotel buildings in Singapore the average energy use intensity EUI in these hotel buildings was determined as 427 kWh 2 . In a similar study of 16 hotels in Hong Kong the average EUI was calculated about 564kWh 3 . And the average EUI for hotel buildings was 160kWh in New Zealand 4 . In recent years the number of hotel buildings has been increasing rapidly in Vietnam. By the end of 2016 the number of upper 3-star hotels .
