Acceleration of BIPV IEA PVS Task 15

Deployment of photovoltaics (PV) in general is seen as one of the main avenues to meeting our energy demands using renewable sources, and integration of PV in the Built Environment has the potential to become a major player. Currently, approximately 3 % of all PV installed is Building Integrated (BIPV), resulting in a niche market for BIPV products. There are more than 100 prototypes of market-ready BIPV products worldwide. However, only a small amount seem to be able to cross the valley of death between product and prototype development and successful large-scale market penetration. Within the IEA PVPS framework Task 15 has been developed to address the major bottlenecks to large-scale market penetration of BIPV. Between 2015 and 2020 16 countries and more than 40 participants will join forces to develop the necessary enabling framework for BIPV deployment acceleration. 

In this presentation the definition of BIPV and the application will be shown besides the work of Task 15.

 There are products on the market, but at the moment it is only a niche market. In addition to the products, there are also prototypes.


Dutch architect Tjerk Reijenga works within the field of sustainable planning and building. Tjerk Reijenga is member of BNA (Dutch Architects Association), ISES (International Solar Energy Society, International Future Living Institute (ILFI) and the Scientific board of the EUPVSEC.

He was an expert for the IEA PVPS task 7 (Building Integration of PhotoVoltaic Systems). Since 2014 he is a member of the IEA PVPS Task 15 (Acceleration of BIPV). He worked with (Dutch Energy Agency) on different actions for the promotion of energy efficiency in China and since 2008 he lives in Shanghai.

His company BEAR-iD has three small studios in the Netherlands, Macedonia and China. BEAR designed many sustainable buildings in the Netherlands and in China. Over 3 MWp of BIPV solar systems were installed in the buildings.

In 1990 we designed the “Solar ship”, a new visitors centre for The Small Earth in Boxtel (NL). This was the first Cradle-to-Cradle building in the Netherlands. The philosophy about closing the loop of resources and the use of bio-based materials in buildings was written down in the book “Sustainable building materials”.
