In a zero energy home annual energy consumption is equal to the annual energy production using one or more available renewable energy resources. In St John's, Newfoundland wind is the readily available renewable energy resource. The average annual wind speed in St John's is 6.7 m/s. This paper presents a feasibility study of a wind energy conversion system based zero energy home in Newfoundland. This study is based on year round recorded wind speed data, solar data and power-consumed data in a typical R-2000 house in Newfoundland. National Renewable Energy Laboratory's software HOMER is used to select an optimum energy system. A detailed analysis, description and expected performance of the system are presented in this paper. This investigation indicates feasibility of a wind energy system based zero energy homes in Newfoundland. (C) 2003 Elsevier Ltd. All rights reserved.
