The O.L.V. Hospital in Aalst, Belgium
O.L.V.-Ziekenhuis in Aalst is one of the best hospitals in the world for researching and curing cardiovascular conditions. Renovations to the hospital included a southfacing 45-degree slope BIPV entrance hall installed by Sapa Building Systems. The facade surface is self-cleaning with a draining system that rinses away any settled dust. The photovoltaic cells are incorporated in between two plates of safety glass. These pre-assembled modules – which are 120x240 cm in size – are connected by aluminium frame sections with built-in thermal breaks and integrated connectors to transport the generated power. The annual capacity is 31,122 kWh of solar energy is fed into the hospital's electrical network.
