A new building thermal model to a better evaluation of the thermal comfort during heat waves

International audienceThis paper is about urban building thermal simulation during summer and heat waves conditions. Summer building thermal behavior are already well performed by popular building simulation software such as TRNsys and EnergyPlus. The effect of the urban fabric could be simulated by an Urban Canopy Models (UCMs) or a District Scale Models (DSMs) but the coupling between these models and a building simulation software requires a high expertise and is not computer efficient. This paper focuses on the construction of a simulation chain of tools that is computer efficient and do not require high expertise to run simulation. The methodology is based on in-situ measurements. The paper describes how the in-situ measurements setup was designed to provide sufficient information to enhance the model settings. It also shows the good accuracy of the model based on the measured data. Key Innovations • Urban building thermal simulation Practical Implications This paper builds an urban building thermal simulation chain of tools that is easy to use and make fast long-term calculation in summer conditions. It is compared to in-situ measurements to assess its accuracy. It will be used to evaluate the thermal comfort of inhabitants during heat waves
