The tourism industry has presented a significant growth over the last decades. Tourism in Greece is a substantial sector of the Greek economy accounting 15% of the country’s Gross Domestic Product (GDP). Hotels are one of the most energy intensive sub-sectors of the tourism industry, which can surely affect global greenhouse gas emissions. This project aims at presenting the effect of using energy efficient techniques, as well as Renewable Energy Sources (RES) such as photovoltaics, in the overall energy consumption of Greek hotels. This project is based on a case study three star category, seasonally operating hotel in the island of Kefalonia, in the Ionian cluster, in western Greece. Data concerning the building’s construction, and the hotel’s electricity, lighting, cooling and hot water production were collected. The annual total energy consumption of the hotel is 95 kWh/ m2 simulation’s software, which approached the actual case, a series of simulations were carried out in order to assess the effectiveness of different energy conservation techniques in reducing cooling loads. While this process, special care was taken in order to maintain internal temperatures within required levels, since it constitutes an important consideration for visitor’s satisfaction. Based on the results of the simulations it was found that the overall energy consumption can be reduced by 10%. Further significant reductions in the energy consumption, may be achieved by the installation of PVs. The combination of energy efficient techniques together with a PV installation on the hotel’s roof caused a reduction by 60% in the electricity consumption from the existing case scenario. The percentage of CO2 reductions from the current case reached 57%, corresponding to 50 tonnes, while the total cost per tonne of CO2 removed for the life-time of the upgrading together with the PV installation is 300€.Furthermore, this project presents a rough cost analysis of the energy efficient techniques followed by an evaluation according to the ...
