Achieving Solar Energy in Architecture-IEA SHC Task 41

AbstractDespite the wide diversity of available solar technologies, solar energy systems are still not considered as main stream technologies in building practice. This may be attributed to several factors such as lack of awareness and knowledge among architects, lack of tools supporting the design process, and lack of solar products designed for building integration. In order to address these issues, the IEA SHC Task 41 “Solar Energy and Architecture” was carried out during 2009 to 2012. The main aim was to promote the use of solar energy systems within high quality architecture. The main expected outcome is an increased use of solar energy in buildings, reducing the non-renewable energy use and GHG emissions. Fourteen countries participated. The work was organized in three subtasks: A) integration criteria and guidelines, B) tools and methods for architects, and C) case studies and communication guidelines. This article presents an overview of the Task's activities and results. The results include an inventory of computer tools, a literature review, a survey on solar systems perception and use by architects, a survey on needs regarding tools for solar design, recommendations for computer tool developers and different guidelines for solar product developers and architects. Finally an extensive collection of more than 250 case studies with integration of solar systems was evaluated and resulting in the online publication of around 65 selected cases demonstrating inspiring solar architecture. The results of Task 41 are also currently being disseminated through seminars and workshops for building professionals
