Data from the US Energy Information Administration illustrates that buildings are responsible for almost half (48%) of all energy consumption and GHG emissions annually; globally the percentage is even greater. Seventy-six percent (76%) of all power plant-generated electricity is used just to operate buildings. Immediate action in the Commercial Building Sector is essential if we are to avoid hazardous climate change. Why integrate wind turbines into buildings? The energy generation is closer to the source (no transmission charges). High energy payback. (Equivalent rates $0.08 to $0.20 per kWh.) Solution to environmental issues; an energy source that is non-polluting, independent of fossil fuels, with the potential for generating renewable energy credits, green tags and carbon sequestration. Wind turbines integrated into buildings have to be substantially different than those used on wind farms. The site surveys must have closer analysis of the effects of the neighboring buildings and the effects of turbulence in order to predict performance. This presentation will reveal some of the issues and solutions available to commercial buildings that are being designed today or retrofitted for the future.
