The building sector plays a special role in the transformation toward a climate-neutral society. It is responsible for up to 40 % of all CO2 emissions worldwide. Politics and society have recognized this importance. Laws and regulations are being defined, and subsidies are being offered. The expansion of solar energy on the way to climate neutrality will activate considerable areas for energy production. One advantage is when existing areas or areas that are to be built anyway are used several times. The integration of solar panels into roofs and facades of buildings extends their function: in addition to energy generation, they provide weather protection, sun protection, light guiding, fall protection, sound and visual protection, thermal insulation as well as the role as a design element. Dieter Moor, CEO Europe of ClearVue PV, reveals what the concrete solutions look like and which trends are currently determining the market.
