Building façades have a critical role in creating urban landscape, can be effectively used to reduce energy and its impact on the environment and incorporate structural seismic resisting elements in the perimeter zone. To satisfy these requirements the authors propose an integrated façade concept to incorporate architectural, façade and environmental design requirements. In Europe remarkable façade engineering development has taken place over the last two decades resulting in elegant facades and a reduction in environmental impact but needs development in Japan to take account of the different environmental climates. To satisfy these requirements this paper proposes the use of a diagonally arranged louver system. In many cases louvers are not installed because of the restricted view and darkness created in the building interior. To overcome these problems a full scale diagonal louver mock up was created to evaluate illumination levels and the quality of the internal environment and external appearance. The mock up was used to measure illumination levels and correlated with results form a lighting analysis tool.
