Abstract
Tourism is one of the main sources of income in some of the countries around the world. The hotel industry has thus become one of the main industries. Hotels are one of the most energy intensive building categories and the hospitality industry contributes to 2% of the world’s CO2 emissions. At present, new buildings can be made energy efficient even from the design stage but existing buildings consume more energy than the new ones. Building energy efficiency retrofitting techniques should be applied, based on economics, to existing buildings to reduce the high energy consumption. This paper presents a review on energy performance and energy intensive areas of some existing hotel buildings at different tourist destinations in the world. Energy retrofitting technologies should be mainly focused on these energy intensive areas. It also provides a review of common retrofitting technologies and past studies on hotel building retrofits. Finally, it discusses the barriers for retrofit projects and a market mechanism to carry out successful retrofit projects. After seeing more than 50% of energy saving in retrofitted hotels, this paper concludes that all possible retrofitting technologies should be implemented from now on and measure the energy performance both before and after retrofitting.
Highlights
Building sector has been identified as one of the highest energy consumers in the world because buildings consume more than 40% of primary energy in most countries [1]
According to the latest published assessment report of the Intergovernmental Panel on Climate Change (IPCC) [2], the building sector accounted for approximately 117 Exajoules (EJ) or 32% of global final energy consumption, 19% of energy related CO2 emissions and 51% of global electricity consumption in 2010
Energy Performance Contracting (EPC) is a methodology used by Energy Service Companies (ESCos) to implement building energy retrofit projects while overcoming above barriers
Summary
Building sector has been identified as one of the highest energy consumers in the world because buildings consume more than 40% of primary energy in most countries [1]. Ma et al [4] have performed a review of past studies on energy retrofits of commercial office buildings, educational buildings and residential buildings. According to Priyadarsini et al [5], past studies and research reveal that hotels are among the most energy intensive of all building categories. This study focuses on the tourism sector, and presents a review of past studies on energy performance and energy retrofits of hotel buildings. The other reason is, even at present, only few Energy Service Companies (ESCos) in the world are engaged in providing successful building energy retrofit projects overcoming barriers as discussed under Sections 3.3 and 3.4. As tourism is one of the main sources of income in some of the countries around the word, this paper will be important to them
