Hotel Sun is an eco-friendly city hotel located in Nicosia, Cyprus. Resource-efficient features and technologies were chosen based on life cycle cost analysis, to minimize the environmental impact and total cost of ownership, meeting the owner’s main requirement to have a truly sustainable facility.
The building envelope was designed to optimize the overall energy performance of the building. Construction materials were selected from locally available and low embodied energy type alternatives. A solar thermal system, supplemented by a heat pump, meets the hot water demand all year round. Air conditioning is provided by an energy efficient chiller heat pump system with heat recovery ventilation. Lighting utilizes LED technology and VFD’s are used extensively on fans and pumps. Low water consumption is achieved in guest rooms and public areas through careful control of water pressure and low-flow fittings. An off-site solar PV system generates sufficient electrical energy to offset most of the electrical demand of the hotel.
Hotel Sun has received final EDGE Advanced Certification from Green Business Certification Inc. (GBCI).
