The CEPA® ENERGY FACADE combines the functions of insulation, heating, cooling, and storage in a single system. CEPA®'s innovative solution enables low-temperature energy distribution across the exterior shell of existing buildings. This makes the facade the perfect ecological choice for buildings undergoing renovation. Due to the external piping, the method is minimally invasive, eliminating the need for relocation of the occupants during the renovation. The technology functions like an energy-saving underfloor heating system with heating and cooling functions, promoting comfort 365 days a year. The existing masonry becomes an energy storage unit. The technology is simple, the possibilities are comprehensive Energy optimization and energy management via the outer shell of buildings is not only the most obvious, but above all the most logical answer to the need for ecological, sustainable construction. We're talking about a simple central energy distribution system that 's open to all energy sources and product manufacturers . There are no limits to the building's design freedom – whether it's a green facade, a wood, stone, or photovoltaic facade: In any case, the implementation of CEPA technology results in an "energy facade." This can be implemented as a ventilated facade (VHF) or as an external thermal insulation composite system (ETICS). The enormous advantage of CEPA technology is that it operates completely independently of the type of energy source and the supply system (electricity, gas, photovoltaics, geothermal energy, pellet central heating system, etc.). Any existing system can be retrofitted and combined with CEPA. This system independence also provides absolute flexibility with regard to any future changes, as it can be easily and economically converted at any time if necessary. The exterior walls of a building, whether residential, office, commercial, or school, can be equipped with CEPA in cooling or heating mode, both for energy efficiency and centrally in the low-temperature range . Retrofitting is possible even while the building is occupied.
