DESCRIPTION:

Coloured PV panels installed on the roof and façade of a building to maximise renewable energy production and provide surplus energy. The design of the PV modules layouts is defined by the PV modules orientation in relation to the sky, the orientation of building longest facades, and the regulatory provision regarding the appearance of the PV façade.

VALUE

The aim of the BIPV and BAPV is making a building energy-positive delivering excess electricity to the grid. The challenge is therefore to show that it is possible to deliver such an excess of electricity and at the same time propose an appealing architectural expression for the building facades. Using solar energy to reduce the need of energy from the grid is an interesting technology since the technology is clean and the energy can be applied directly to use.

APPLICATION

BIPV and BAPV panels were integrated into the school building in the Voldsløkka project, delivering a total annual energy production of 230,000 kWh. This corresponds to 2 kWh/m² per year of surplus electricity, enabling the school to operate as a plus-energy building. The system combines black and bi-coloured PV panels installed at a 20-degree angle. This angled placement reduces the available façade area due to window openings and façade edges. To meet the building’s energy targets, parametric design tools were used to determine the optimal number of PV modules for different panel orientations, and the resulting electricity production was calculated accordingly. The project demonstrates that large PV-integrated façades can achieve plus-energy performance while maintaining a strong architectural quality.
