In a project financed by Innosuisse Amenti Together with the Scuola Universitaria Professionale della Svizzera Italiana (SUPSI), we have developed a planning methodology that enables the precise prediction of yields from roof- and façade-integrated photovoltaics. It automatically takes into account shading caused by building offsets and the shadows cast by neighbouring buildings, trees and terrain.

Typical for Amenti is the connection to Switzerland-wide databases, which means that relevant geodata is seamlessly integrated. Within a few minutes, we modelled the building and simulated an optimal façade photovoltaic strategy. The results are presented below with the Amenti Planning tool with the real construction project and the measurement data using the example of the property at Spiegelgasse 11/15 in Basel, AUE - Office for Environment and Energy - Solarchitecturecompared:

• Area of active façade modules - Amenti planning tool: 1,085 m² | actually built: 1,132 m²
• Photovoltaic yield - Amenti planning tool: 52,979 kWh/a | Effectively measured: 53,000 kWh/a

With Amenti and its most comprehensive database of building regulations in Switzerland, feasibility studies can be created in no time at all. Our platform combines Building regulations, Precise 3D terrain models and Profitability calculations in a single tool. By simulating different scenarios - from Shading analyses about Solar potential through to the profitability of construction projects - planners can make well-founded decisions at an early stage.

Thanks to the Seamless integration of construction cost benchmarks (Keevalue) and market & yield data (FPRE) our users receive a complete, data-driven decision-making basis for sustainable and economically optimised property development.

Façade-integrated PV solutions can thus be evaluated efficiently and based on data in the early planning phases - and another step towards sustainable and energy-efficient buildings!
