1. Introduction The international Energy Agency (IEA) predicts that between 2005 and 2030 years, the consumption of electricity will increase by 39 % in residential, by 17 % in industrial and by 63% in commercial[1]. Addationally, it is estimated that 97.5 TWh of energy was used in hotel facilities worldwide in 2001 and 39 TWh used by European hotels in 2000 which nearly half of the world total hotel energy[2]. In line with this, such sectors have realsed significant amount of greenhouse gas emissions. Therefore, Energy efficiency is one of the most powerful weapons for energy costs saving, energy security, combating global climate change and boosting sustainable economic development. Building sector shares a large part of total energy…show more content…
Energy Efficiency also improves the service of capital equipment, enhances guest comfort, and demonstrates a commitment to climate change. In hotel buildings, various types of energy are required to operate its departmental services depending on the cost of the fuel and interests. Some of them are electricity, liquefied petroleum gas, diesel fuel, coal, natural gas. However, in hotel facilities, electricity is the primary form of energy for air-conditioning, heating, lighting, vertical transportation lifts, escalators, and kitchen equipment[6]. Liquefied petroleum gas and natural gas is the next most common energy type for cooking and water heating[6]. Furthermore, depending on the age and size of the hotels their energy, operations, and maintenance cost are also variable. Space conditioning (heating/cooling, ventilation and air-conditioning) is the largest single end-user of energy in hotels, accounting for approximately half of the total consumption[7]. From these, outdoor weather conditions and floor areas are among the main factors affecting energy use in hotels. The indoor temperature levels also greatly influence the quantity of energy consumed in a building. Domestic hot water is commonly the second largest user, accountrs up to 15% of the total energy demand. Lighting can fluctuate between a range of 12-18% and up to 40 % of a hotel’s total energy consumption, depending on the category of the establishment[2]. Therefore, it is necessary to implement effective energy management system to identify costs and potential savings by involving employees in energy saving action plan. However, once an effective energy management is in place, the next step is to start controlling and supervising energy consuming equipment. When the Hotel energy consumption after implementing effective energy management systems
