BUILDING RETROFIT USING FACADE-INTEGRATED ENERGY SUPPLY SYSTEMS

Abstract

A new approach of highly-efficient thermal refurbis hments of multi-family buildings is presented that s a high potential to reduce costs and simplify the ren ovation processes significantly. This approach is b a ed on 10 prefabricated curtain wall elements that integrate components for the energy supply system such as hea t pumps, PV panels and all the necessary pipework for supply and waste water lines. By using pre-fabricated cur tain wall elements, scaffolding and the relocation of inhabit ants can be avoided. Three different system concepts have been evaluated and compared to a reference retrofit in terms of p rimary energy and life cycle costs. It has been shown that e new concepts can reduce the primary energy 15 consumption significantly while reducing the costs over the lifetime of the system. Finally, a functional mockup of such as pre-fabrica ted façade was constructed and successfully tested in the laboratory.
