Joint project "Building-integrated photovoltaics"

 

In view of the strategic potential of building-integrated photovoltaics (BIPV) and the significance of the renovation of the existing building stock over the next few decades it will be crucial to develop this technology. The project aims to study technological, spatial and socio-economic parameters and contribute to advancing certain practices by addressing BIPV in urban renewal projects.

Project description (ongoing research project)

In spite of technological advances and economic developments, only a small portion of the solar power potential is currently being exploited in urban areas. Various types of obstacles have to date restricted the large-scale implementation of BIPV into urban renewal processes. Typical obstacles include the costs (partly attributable to technology choice and modest volumes, which in turn are linked to other factors), the lack of awareness, conservative attitudes and habits in the renewal process, the absence of ab initio planning of photovoltaic solutions, and the lack of coordination between the various organisations working on a building.

Aim

Only a clear identification of the operational barriers and the development of coherent holistic strategies – from industrial production of photovoltaic building elements to implementation by the end users (house owners, architects, public authorities) – can lead to a relevant contribution and a precise prioritisation of the efforts. The project will focus on the operational strategies crossing over obstacles for large-scale advanced BIPV integration into urban renewal processes. More specifically, the main objectives include:

  • a clear identification of the operational barriers
  • the development of alternative and innovative approaches in line with coherent holistic strategies – from industrial production to implementation by end users, achieving optimal equilibrium between demand and supply aspects
  • the formulation and implementation of concrete recommendations to bring about a significant change in practice in this area

The findings will be addressed to four main target audiences: legislators and regulators at the federal, cantonal and municipal levels; owners and other decision-makers along the value chain; architects, engineering offices; suppliers, integrators, construction companies.

Relevance

Urban renewal in Swiss cities and urban agglomerations simultaneously reduces end energy consumption, promotes the use of renewable energy and cuts CO2 emissions. BIPV will directly help to offset the loss in electricity production from nuclear energy by increasing the use of renewable energy while maintaining an acceptable balance between the conservation and use of financial resources. It has attractive potential in terms of transferability and could have positive repercussions for urban, architectural and constructive design practices.
