Architects and designers are encouraged to use energy harvesting devices as a strategy to balance energy consumptions of buildings, aiming to minimize the maintenance cost of buildings and meet the criteria of net-zero energy. This research aims to provide simple and straightforward design methodology to architects to integrate wind harvesting energy devices to their project. The proposed design method considers orientation and scale of buildings, contextual conditions, as well as on-site wind speed data to optimize building-integrated devices (BID) performance and financial efficiency of the energy produced. It will achieve a more efficient resource utilization by better integration of devices to buildings and by repartition of cluster of devices over large surfaces. Building envelopes are becoming smarter; Building's façade or rooftops are available for new function of building-integrated device (BID), such as photovoltaic panels and wind turbines to produce clean energy. Following an in-depth analysis on the performance and behavior of existing building that integrates BID devices, we further studied the relationship between building design and BID. The goal is to developed strategies to compensate the unstable performance of BID caused by air flow turbulences and to optimize the wind amplification effect of buildings.
