Abstract

This paper presents the results of a pilot project on rooftop wind in Perth, Western Australia, that aims to gain insight into best practice for placement of rooftop wind systems. Measurements of the air flow over a local Council building in Perth are captured using an ultrasonic anemometer installed on a 6.1 m mast on the top of the building. Data collected over a period of 6 months indicates that the mean wind speeds are too low for a rooftop wind system to be feasible at this location and demonstrates the importance of conducting wind resource assessments for potential rooftop installations. The air flow around the building has been modelling using “meso- to micro-scale” forecasting software called A2C. Use of the software was investigated as an alternative to more complex, expensive, CFD codes but was found to not have sufficient resolution for accurate prediction of turbulence length scales.
