Focus on thermal damping

Thermal damping (or amplitude attenuation) is an essential concept in the field of energy efficiency and thermal comfort in buildings. It represents the ability of a wall to dissipate a thermal wave and attenuate its intensity. Complementary to effusivity, this criterion plays a major role in determining summer comfort in […]

Focus on thermal effusivity

When summer temperatures reach high levels, thermal comfort becomes a priority. To understand how to maintain a comfortable temperature inside buildings during hot periods, it is essential to understand the concept of thermal effusivity. Definition of thermal effusivity: Effusivity is a measure of a wall's ability to exchange […]

Focus on thermal diffusivity

In the field of thermal engineering, diffusivity plays a crucial role in understanding heat transfer phenomena. Focus on this characteristic, how it is calculated, what it represents, and its importance for summer comfort. Thermal diffusivity: Diffusivity is a physical quantity that describes the […]

Guide to thermal phase shift

In the construction industry, thermal phase shift refers to the time it takes for a thermal wave to pass through a wall or material. In other words, it refers to the time lag between the peak outdoor temperature and the moment when this heat reaches the interior of the building. Understanding phase shift and how it is calculated […]

How can we ensure comfort in buildings during the summer?

One of the effects of global warming is an increase in heat waves, their duration, and their intensity. France is particularly affected by these extreme temperatures, mainly due to the density of buildings, impermeable soils, and the lack of vegetation in certain regions. So, what are the factors that influence […]

What criteria should be considered when choosing materials for summer comfort?

Certain properties of building materials play a decisive role in summer comfort. It is therefore advisable to take them into account when designing buildings, as well as in renovation projects, particularly in warmer regions. Among these properties, thermal inertia represents the capacity of a wall or […]

Understanding the 6 key parameters of thermal comfort

With the increase in heat waves in recent years, it is crucial to understand the challenges of thermal comfort in order to enjoy comfortable buildings in all seasons. Whether in RE2020 construction or renovation, buildings with optimized thermal comfort consume less energy in winter and summer, and […]

Choosing the best insulation for a wood-frame construction

Wood-frame buildings are becoming increasingly popular due to their durability, low carbon footprint, and design flexibility. However, to ensure optimal energy efficiency, it is crucial to choose the right insulation. So, what is the best insulation for a wood-frame building? In this […]

How can you optimize summer comfort with RE2020?

Effective January 1, 2023, the 2020 environmental regulation (RE2020) replaces the previous 2012 thermal regulation (RT2012), which governs building construction. It focuses on three new objectives: reducing the carbon impact of buildings, optimizing their energy performance, and ensuring summer comfort. In this article, we will explain what […]
