About

The whole building envelope has a homogeneous appearance thanks to glass elements used as cladding and tiles. Both the facade and the roof are fully covered with photovoltaic elements where the front layer is a laser printed brown glass which hides mono-crystalline silicon cells. The PV cells hidden by the front glass which reduce the electricity production by about 39%. These modules have been specifically developed for this project.

“Technology… is not only a useful means… it has a meaning and a powerful form… Is that still technology or is it architecture? Wherever technology reaches its real fulfilment, it transcends into architecture. Architecture wrote the history of the epochs and gave them their names. Architecture depends on its time. That is the reason why technology and architecture are so closely related. Our real hope is that they grow together, that someday one be the expression of the other. Only then will we have an architecture worthy of its name: Architecture as a true symbol of our time” Mies van der Rohe, 1950“.

New solar building technology enables fascinating design opportunities. Let architecture be reshaped by renewable energy production.

The main goal of this website is to promote the construction of solar buildings by shifting the attention from technology to architecture. Real examples and stories of best practice prove today the feasibility and the quality of solar buildings in terms of aesthetics, construction technology and sustainability.


SUPSI (University of Applied Sciences and Arts of Southern Switzerland) is one of the nine professional universities recognized by the Swiss Confederation.
Founded under federal law, SUPSI offers more than 30 Bachelor’s Degree and Master’s Degree courses, characterized by cutting edge education which unites classical theoretical-scientific instruction with a professional orientation. Great care is given to research, carried out in key sectors on competitively acquired projects with large European and national agencies or mandated by organizations and institutions.

ISAAC (Institute for Applied Sustainability to the Built Environment) covers research areas associated with renewable energies, the rational use of energy, the refurbishment and maintenance of buildings and also energy planning at regional and local levels.
Research projects are based on a variety of regularly-revised methods, and benefit from productive collaboration agreements with other research units, public bodies, non-governmental organizations and industries. The Institute promotes technological transfer in a number of developing countries.

The Innovative Envelope research team of ISAAC has acquired expertise over last 15 years as a result of various research projects on integrated photovoltaic (BIPV-Building Integrated Photovoltaics) conducted both at national and international level. It hosts the Swiss Competence Centre for BIPV.
Research was carried out in collaboration with manufacturers whilst, working closely with architects and installers. Tests were carried out to qualify and validate the new concepts, both in the laboratory and on site in real conditions. The research focuses mainly on the development, analysis, experimentation and demonstration of innovative and sustainable solutions for multi-functional building envelope systems suited to future zero-emission buildings.


Swissolar is the Swiss professional association for solar energy. It represents the Swiss solar industry, planners, installers, producers and other players in the solar industry who support the goals of the solar industry. We are committed to a secure, renewable and resource-saving energy supply for Switzerland by 2050 at the latest, in which solar energy plays a major role.

Solar architecture is an important element of these efforts. This conceptual approach fosters the construction of buildings that create the greatest possible comfort for users with a minimum energy requirement and make optimum use of the potential of the sun. Various topics such as energy, technology, design, construction, ecology and economy are to be optimally incorporated into architecture.

Swissolar hosts a expert commission on solar construction to exchange about current and future developments of solar construction and its further development.


The Swiss Energy program was set up by the Swiss Federal Council to promote energy efficiency and renewable energy. The program sensitizes public opinion in Switzerland towards energy issues, promotes innovative projects and supports training and professional development offers for specialized personnel. The program thus makes it possible to make a significant contribution to making innovations take root and become visible. Renewable energy or efficient use of energy: Swiss Energy provides its advice and informs interested parties.
