Digital Urban Simulation | Name of the project Radiation analysis and PV potential In order to estimate the solar potential of the buildings in the HQ , we use the radiation analysis tool of Ladybug to generate a solar irradiation map. We develop further a tool that takes the results from Ladybug and estimates if certain areas are eligible for the installation of PV or not and generates a visual output of the suited areas. The decision is made based on an economic calculation and the efficiency of the PV modules. Taking into account the price per m2 of PV systems (1000 CHF/m2), the average lifetime (30 years), the efficiency (16%) and the market price of electricity in Switzerland (0.2 CHF/kWh), Radiation we come to the analysis conclusion and that PV a threshold potential of 1040 kWh/m2 of solar irradiation is needed in order to make PV profitable. In order to estimate the solar potential of the buildings in the HQ , we use the radiation analysis tool of Ladybug to After generate running a solar the irradiation script for map. both We existing develop situation further a tool and that planned takes the intervention, results from we Ladybug noticed and an estimates increase if certain of 5’780 areas MWh are PV eligible potential for the in installation the “Syntheseplan”. of PV or not This and represents generates a an visual increase output of of 32% the suited from areas. the initial The decision is made based on an economic calculation and the efficiency of the PV modules. Taking into account the potential of 18’050 MWh. Moreover, the new image of the areas suited for PV generation shows a price per m2 of PV systems (1000 CHF/m2), the average lifetime (30 years), the efficiency cy (16%) and the market much better distribution with bigger areas on flat roofs. Even with the significant improvement, the PV price of electricity in Switzerland (0.2 CHF/kWh), we come to the conclusion that a threshold hold of 1040 kWh/m2 of electricity production would cover only ca. 26% of the total electricity demand of the present quarter solar irradiation is needed in order to make PV profitable.
