Abstract: The achievement of the targets for reducing greenhouse gas emissions set by the Paris Agreements and the Swiss federal law on the reduction of greenhouse gas emissions (CO2 law) requires massive use of renewable energies, which cannot be achieved without their adoption by the general public. The solar cadaster developed as part of the INTERREG G2 Solar project is intended to assess the solar potential of buildings at the scale of Greater Geneva—for both industrial buildings and for in idual residential buildings—at a resolution of 1 m. The new version of the solar cadaster is intended to assess the solar potential of roofs, as well as that of vertical facades. The study presented here aims to validate this new version through a comparison with results obtained with two other simulation tools that are widely used and validated by the scientific community. The good accordance with the results obtained with ENVI-met and DIVA-for-Rhino demonstrates the capability of the radiative model developed for the solar cadaster of Greater Geneva to accurately predict the radiation levels of building facades in configurations with randomly distributed buildings (horizontally or vertically).

Abstract: Numerical simulations of a spatially developing transitional flow in a vertical channel with one side uniformly heated and subjected to random velocity fluctuations at the inlet have been performed. Two characteristic frequency bands are observed in the flow, near the heated wall. The ability of the Proper Orthogonal Decomposition and the time-domain Spectral Proper Orthogonal Decomposition (SPOD) to decompose the flow is assessed, and SPOD is shown to be a powerful tool, as it is capable of separating the most energetic modes into two great families whose frequency content matches the frequency bands previously identified. The spatial structure of the modes is described, and their contribution to the turbulent heat transfer and velocity-temperature correlation is evaluated. Finally, the modes are linked to coherent structures that are observed in instantaneous visualizations of the flow, and a scenario of the development of the coherent structures in the laminar-turbulent transitional process is proposed.
