An experimental study was carried out on a full-scale passive building equipped with global and local instrumentation with the aim of characterizing the energy charge and discharge processes and their coupling to the outdoor thermal stresses, especially natural ventilation in the summertime. The characterization of both charge and discharge process...

The thermal performance of the building envelope is critical to reducing the energy consumption of buildings and increasing the building energy efficiency. Studies on the evaluation methodology for thermal performance of building wall is of great significance for new building accreditation, retrofitting energy efficiency of old buildings, energy co...

Living envelopes, such as biological skins and structures built by animals, are functional and sustainable designs resulting from years of evolution, conditioned by biological and physical pressures from the environment. When building a home, animals demonstrate inspiring strategies to protect themselves from predator threats and external climatic...

Building envelopes can manage light, heat gains or losses, and ventilation and, as such, play a key role in the overall building performance. Research has been focusing on increasing their efficiency by proposing dynamic and adaptive systems, meaning that they evolve to best meet the internal and external varying conditions. Living organisms are re...

Building envelopes have a key role to the occupant comfort. Their design, implementation and functionalities highly influence the overall building performance. Some current research focus on strategies to improve buildings energy efficiency while minimizing their impact on the environment. Bioinspiration i.e., the inspiration of biological organism...

Green infrastructure has a role to play in climate change adaptation strategies in cities. Alternative urban spaces should be designed considering new requirements in terms of urban microclimate and thermal comfort. Pervious pavements such as green parking lots can contribute to this goal through solar evaporative cooling. However, the cooling bene...

The aim of the present work is to propose a methodology for the use of thermoelectric modules (TEM) as an alternative to conventional heat flux sensors, for estimating convective and radiative heat flux. In this experimental study, the performance of TEMs as heat flux sensors is compared to that of the heat flux sensor (HFS), a type of conventional...

By distinguishing the use of hydrophilic porous medium (HPM) as an alternative to conventional building materials, an experimental evaluation is presented here. The objective of this study is to analyse the coupled hygrothermal behaviour of a HPM under various climatic conditions. The results indicate that the addition of HPM to the building wall a...

Considering the use of Peltier modules as alternatives to conventional flux meters, an experimental evaluation comparing these two types of sensors is discussed here. The interest in performing this evaluation lies in the difference in the cost and the higher thermoelectric power of Peltier modules compared to conventional flux meters. The results...

Thermal performances of building walls are significant for energy conservation. However, very few non-destructive evaluation methods exist to quantitatively diagnose the building walls in situ due to the walls’ large thickness. Moreover, most of the existing methods are inconvenient to implement in situ and take a long characterization time. This p...

Non-destructive thermal diagnosis of walls is a crucial theme for the renovation of old buildings, the examination of building structures and the accreditation of new buildings. Nevertheless, there are very few diagnostic methods for the characterization of thick walls. In this study, an innovative approach that combines terahertz radiation method...

Une plateforme d'essais (bâtiment monozone) a été instrumentée afin d'appréhender les couplages existants entre ventilation naturelle et apports solaires directs, et stockage&déstockage d'énergie sensible dans le sol. Elle est dotée au Sud d'une dalle béton, d'une façade vitrée, de protections solaires et sur les façades Sud et Nord et en shed, d'o...

Méthodes de rayonnement terahertz et de sondes thermiques planes en vue de l'examen non-destructif de murs épais pour le diagnostic thermique de bâtiments.

Checking the quality of bonding areas between metallic plates is crucial in many industrial fields. This paper describes a new detection method of the flaws in bonding areas between two metallic (or thermally conductive) plates by flash method. In such situations, the in-plane heat diffusion in the metallic conductive plates is blurs the defect bou...

The recent evolutions of the thermal regulation and the conclusions brought in the Grenelle environment forum encourage a part of the housing builders to be inspired by the traditional housing environment. The ecological impact of materials, for manufacturing, use and destruction, is more and more taken into account. We find in this way the brick o...

Résumé -Le contexte actuel de démarche écologique dans la construction remet au goût du jour les matériaux d'origine naturelle comme la pierre. Soumis aux conditions micro-climatiques, ceux-ci voient leurs caractéristiques thermophysiques évoluer dans le temps. Il est donc nécessaire de pouvoir disposer d'outils de caractérisation permettant d'obse...
