Photovoltaics can be used directly in building and renovation projects and serve as a construction material in their own right. Integrating solar panels into facades and roofs can transform buildings into electricity producers and reduce CO2 emissions. To develop and promote this technology, Be-Smart project partners will design multifunctional solar panels that not only produce energy but also do the job of other building materials with insulating, soundproofing or aesthetic qualities. The project partners will also develop a methodology for architects and construction companies and find ways to drastically reduce the costs of BIPV.
