[Expertise] Thermal comfort: how to face more frequent heat waves? – Part 2

In our Part 1 article, we have introduced Thermal comfort principle and some essential passive design ideas to optimize buildings to frequent heatwaves. In this article, we continue to introduce other simple yet essential way to avoid thermal discomfort in a building. Optimization of the envelope Thermal insulation, compactness and glazing rates should be optimized to minimize heating and cooling

[Expertise] Thermal comfort: how to face more frequent heat waves? – Part 1

In the current context of ever more numerous and intense heat waves, the notion of thermal comfort in buildings is more relevant than ever. In June, France experienced temperatures 10°C to 15°C above seasonal norms. July and August also brought their share of heat waves! Beyond national climate objectives and the reduction of its impacts, the construction sector must also

[Expertise] Energy modelling: a powerful tool for sustainable buildings

Energy modelling is a whole building simulation process that engineers, architects, and researchers use to model the energy consumption of heating, cooling, ventilation, lighting, electronic equipment, and process loads. The simulation can give hourly time steps results or even sub-hourly time steps results (for example 15 minutes) which makes it possible to carry out a detailed analysis of the thermal

[Expertise] How to optimize buildings airflow and air temperature with Computational Fluid Dynamic (CFD)

Computational Fluid Dynamic (CFD) is a tool used to analyse fluid flows and temperature. In the case of building and environmental engineering, it can be used for internal spaces (large space as warehouse, exhibition space or workshop) or external spaces (district, neighbourhood or cities). In internal space, CFD is used to calculate thermal comfort via the calculation of air speed, air temperature, “age” of air
