Abstract: Since the European renewable energy directives set the
target for 22.1% of electricity generation to be supplied by 2010
[1], there has been increased interest in using green technologies
also within the urban enviroment. The most commonly considered
installations are solar thermal and solar photovoltaics. Nevertheless,
as observed by Bahaj et al. [2], small scale turbines can reduce the
built enviroment related CO2 emissions. Thus, in the last few years,
an increasing number of manufacturers have developed small wind
turbines specifically designed for the built enviroment. The present
work focuses on the integration into architectural systems of such
installations and presents a survey of successful case studies.
