Crossflex: Concept and early development of a true building integrated wind turbine

Abstract: a b s t r a c tThis paper describes the concept development and work to date, of an innovative 'true' building integrated wind turbine. The context for this is the role of small-scale renewable energy in addressing climate change. In the UK a number of small wind turbines have reached the market, however, in almost all cases, these are existing HAWT or VAWT tower mounted systems. Due to their inherent design qualities, and issues such as planning requirements, these have much reduced output due to their form a… Show more

“…The idea of bringing a wind energy system into urban areas is more challenging because of limited available space and the adaptation of the wind turbine to the existing infrastructure. Many researchers have proposed ideas of wind energy systems that can possibly be installed in urban settings for local energy generation [11][12][13][14]. These systems feature additional augmentation systems, either utilizing the building geometry or retrofitted onto the building or a combination of these.…”

“…The results of the research show that the improvement on the design could lead to an increase in theoretical efficiency of about 48% (conservative) or 61% (optimistic). The concept of utilizing the building shape for wind energy harvesting is also presented by Sharpe and Proven [32]. The study indicates that improved visual integration into new and existing buildings and augmentation airflow can be achieved by utilizing a lightweight cowling system.…”

“…The rotational speed of the VAWTs were very high (>400 rpm) while the tip speed ratios were in the range of 1.28-1.29, making it preferable for electricity generation. Sharpe and Proven (2010) carried out detailed work on the concept and early development of a building integrated wind turbine in Scotland. The Crossflex proposal used in this investigation is based on the Darrieus turbines approach, consisting of two or more flexible aero foil blades attached to both the top and bottom of a vertical rotating shaft.…”
