Abstract: Cooling energy refurbishment of buildings can be achieved by coating the outdoor walls with paints that have high solar reflectance (0.3-2.5µm) and high thermal emittance (4-80µm). In this presentation, the thermal performance of some paints is studied through an outdoor experiment. In a second part, the inwards conductive flux for a non-insulated wall is modelled with a premise energy budget’s module. Lastly, we introduce the construction of a 1/10th reduced scale model of 4 street canyon set to allow the validation of a model coupling mass and thermal transfers between buildings and urban microclimate. Boundary conditions and energy balance are discussed through installed sensors.
