PV-NORD – PAVING THE WAY FOR BIPV IN NORTHERN EUROPE

摘要

This paper summarises PV-NORD, an EU project on building integrated photovoltaic systems. In Northern Europe, the harsh climate, low energy prices and conservative construction traditions have limited the use of grid-connected PV systems in buildings. Too little attention has been paid to the fact that building integrated photovoltaics (BIPV) is the only high quality renewable source of electricity possible in an urban environment. Based on the EU White Paper, the purpose of PV-NORD is to catalyse the development of BIPV in Northern Europe and to provide the necessary knowledge and direct demonstration to put BIPV on the agenda of the coming years' energy planning. The partners represent different interest groups in PV exploitation, and form multi-knowledge groups, addressing the barriers from different angles, based on eight demonstration buildings in the participating countries. The thematic research is organized into five tasks: Aesthetics and PV integration, Power and electricity, Environment, Management and IT, and finally Financing and ownership. In this paper, the potential of BIPV is demonstrated by the PV-NORD building Kollektivhuset, central Copenhagen. This is a façade renovation project for a multi-storey housing block for handicapped tenants. The photovoltaic modules are mo unted in the glazed balcony parapets with a coloured sliding panel behind. This panel can be slid so as to utilise the heat from the PV modules or block the radiating heat from entering the balcony. The modules thus have multiple functions: as radiators for the balconies, as sound insulation, as electricity generators and aesthetically as dynamic façade elements.
