dc.descriptionHotels are considered one of the most energy consumers in the building sector and are thus responsible for quite large amounts of carbon dioxide emissions. The major part of this energy is utilized for water heating, space heating and cooling, and lighting. The study is divided into two main parts; in the first part, energy potential of hot water in the hotel sector of Libya is estimated, and the opportunities of saving an important part of this energy through utilizing solar energy is also investigated. The study is based on distributing questionnaires to a nine big cities in Libya. The information that was gathered from the questioners with other information from different sources were analyzed and projected all over Libya. The potential of hot water in the hotel sector and the energy that might be saved if we use solar energy is estimated. The study has shown that the total energy consumption of hot water in the hotel sector of Libya is over 18.54 GWh/year according to the current situation of the hotel sector, and the cost of heating is over 1.3 million Libya Dinar. Over 70% of this energy can be saved using solar water heating technology. The study has also shown that the technical potential to cover 75% of the load by solar energy is required 25,386 m2 of collector area whereas; the economic potential is dropped to 663 m2. The second part of this study is a case study on a Plasma hotel where the most of the information required to conduct such study are available. Sizing the main components of the solar system, layout design, payback period, and the economic and environmental benefits are conducted through the use of very famous software program namely PolySun. The study has shown that the required SWH system size that covers 70% solar fraction is about 40 m2 of vacuum tubes collectors and tank volume of 3500 liters. The estimated cost of the system is 32,260 L.D and the payback period is 8 years.
