PV Active roofs and facades

 

In Denmark we have a vision to transform our energy system to renewable energy by 2050. This conversion requires that we focus on a number of renewable energy technologies. For example, studies developed in the project ‘Energy Across’ show that solar panels on roofs and facades have the potential to provide 15 percent of electricity production in the metropolitan area by 2050. If we are to benefit from this potential, it is necessary to test different models for how solar cells can be better integrated into buildings.

The projects ‘Low Cost Active House BIPV’ and ‘PV Active Roofs and Facades’ aim to develop new innovative models that enable increased integration of photovoltaics into buildings. The projects look at the building projects holistically and assess the needs of the building owner for aesthetically pleasing buildings, profitable construction, operation and energy savings, as well as societal needs in relation to future energy systems.

As part of the projects, building owners are offered financial support of 8% of the total construction cost for setting up solar panels. In addition, they are offered support in the form of 60% to the preparation of conceptual designs, as well as for the measurement of the panels’ ongoing performance in the first two years after making the switch to solar panels.

PV Active Roofs and Facades

The project ‘PV Active Roofs and Facades’ is targeting the social housing sector and aims to disseminate effective profitable building integrated photovoltaic solutions in the form of either building integrated PV modules in the roof solutions or as part of general renovation projects and new construction.

The project aims to install a total of 2.6 mwp of BIPV solutions in housing associations. This project will contribute to the development and testing of new solutions, as well as the development of good business cases that can help to disseminate knowledge about the potential for installation of solar panels in the public sector.

Based on experience from the project, a number of recommendations have been made for solar power as part of the overall energy infratructure in Denmark and how the legislation in support of sustainable development in the area will look going forward. This work also includes experience from the project Low Cost Active House BIPV.

Low Cost Active House

The project is targeted at professional developers and aims to promote the spread of BIPV solutions in residential and public buildings. The project partnership will do this by developing architecturally customized and cost effective solutions that fully or partially replace traditional roofing and facade materials, which are an integral part of an overall concept for the future Active House construction.

The solutions are demonstrated on major new construction and renovations in housing associations, businesses and municipalities. The focus will be on energy conservation and proven performance in accordance with international Active House specifications.

Based on experience from the project, a number of designated recommendations have been made for solar power as part of Denmark’s overall energy and how the legislation can move forward in support of sustainable development in the area. This work also includes experience from the project PV Active Roofs and Facades.
