An energy harvesting system utilizing wind pressure fluctuations on high-rise building envelope

Abstract

In this paper, the new energy harvesting system is proposed by using wind pressure fluctuations which are one of existing energy sources that were not taken into consideration around high-rise buildings. The proposed system carries out the role of building envelope also. This research is divided in two parts. At first, Computational Fluid Dynamics (CFD) and wind tunnel experiments are performed for investigating the wind pressure that occur around the high-rise building. Secondly, based on the result of wind pressure analysis, the optimal mechanism is devised and the prototype of the energy harvesting system is designed to verify the possibility of utilization of wind pressure fluctuations through the small wind tunnel experiment, harmonic excitation experiment and numerical analysis. As a result, the performance of proposed energy harvesting system is numerically and experimentally validated.
