It draws together ten years of work, from the air moving behind a ventilated façade to the question of which roofs a whole agglomeration should equip first. The manuscript is openly available on HAL. https://martin-thebault.fr/en/news/urban-radiation-decomposed/ https://martin-thebault.fr/en/news/urban-radiation-decomposed/ Wed, 10 Jun 2026 00:00:00 GMT Guillaume Le Gall's work on higher-order orthogonal decomposition of shortwave radiation in urban contexts is out in the International Journal of Thermal Sciences. Three-dimensional urban geometry makes incident solar radiation vary across many spatial and temporal scales at once. The paper shows that a small number of modes can stand in for a full simulation of that field. https://martin-thebault.fr/en/news/rooftop-pv-detection/ https://martin-thebault.fr/en/news/rooftop-pv-detection/ Tue, 18 Mar 2025 00:00:00 GMT Our building-wise detection of rooftop photovoltaic systems across heterogeneous French urban and rural territories is published in Applied Energy. Planning what to install next is much easier when you know what is already there. The method applies convolutional neural networks to aerial imagery, building by building, at national scale.
