Article
This paper proposes a sizing method to guide the design of water-circulating radiative sky cooling systems and water-based energy storage solutions. Following this method, the choice of operational flow rate in the radiative sky cooling (RSC) panels and the water storage is based on four indicators: sub-ambient temperature, cooling power density, m...

The facade of buildings generally remains an untapped energy resource due to the need for aesthetics. From this point of view, the development of unglazed thermal solar panels as a facade element, similar to conventional cladding, can be a relevant solution. However, the need for architectural integration of these absorbers conflicts with the need...

In this article it is presented an innovative façade system with a solar thermal system. The developed solar system can be classified as modular unglazed collector, designed for low temperature energy capture. It is compatible with a solar combined system that integrates a solar heat pump. The external appearance of the building remains untouched t...

L'étude concerne une modélisation sous COMSOL du couplage entre un système de production d'eau froide par Radiative Sky Cooling (RSC) et une Pompe À Chaleur (PAC) air/eau, et l'estimation des performances de ce système couplé en vue d'assurer les besoins en climatisation d'un bâtiment tertiaire à Bordeaux. Ces panneaux RSC, permettent par circulati...

Within the existing European building stock, a large share of the suburban multi-storey residential building stock was built in the 60’s-70’s, when there were only few or no requirements for energy efficiency. These buildings are characterized by very high energy consumption, low air quality due to poor ventilation, and low architectural value. In...
Article
Present trends on solar thermal systems for building integration define the need of integrated solar technologies for façades. Although other possibilities exist for solar thermal systems in new buildings, solutions for a suitable integration of solar thermal systems into building retrofitting actuations are needed.

This paper presents a multifunction timber wall concept. It is adapted to create frame and envelope of multi-storey buildings. This wall is composed of a reinforced CLT thin panel to support the loads. Other layers are used to provide insulation, internal and external coatings. In this study, Solid-beams are chosen to reinforce the CLT panel. Bendi...

Cette étude porte sur la modélisation et l’étude expérimentale de capteurs solaires développés et fabriqués par INEF4 dans le cadre du projet BATISOL. Ces capteurs sont modulaires, opaques, basse température, Low-Cost, et totalement intégrés en façade derrière une solution de bardage métallique. Dans une première partie est présenté le modèle de si...
Article
Full-text available
A method for accurate description of coupled heat and mass transfer phenomena within wood-walls using linear, low-dimensional models has been proposed. The partial differential equations that describe the hydrothermal behaviour of the wall are first linearized, thus decoupled and finally reduced to a very low number of ordinary differential equatio...
Article
The experimental results obtained by the thermophysical characterization of a wall made of stacked laminated solid-wood planks are reported in this article. The interface between two logs is filled with a felt packing that is compressed under the weight of the upper plank. The characteristics which affect heat, air and water vapour transfers throug...

RÉSUMÉ : Le développement de la construction bois est un enjeu important et une réponse efficace pour la réduction des impacts environnementaux liés au secteur du bâtiment. Les maisons Bois Massif réalisées à partir de madriers empilés constituent la seule solution de construction « mono matériau » et par filière « sèche » sur le marché. Ces techni...
Thesis
Full-text available
The development of the wood construction sector is an important stake and an efficient response to a need for reduction of the environmental impacts related to the building sector. Massive timber structures made of piled beams are the only solutions based on "mono material" construction and "dry construction" in this sector. These construction tech...

Project
MCPBAT aims to develop a Bio-based modular compact thermal energy storage (TES) for Solar and HVAC applications (Hot water, heating and cooling). Due to its compactness and thermal performance, this system is expected to allow better use of thermal energy in building while reducing the space occupied.
Project
The objective of the H2020 funded project E2VENT is the development of a facade module based on ventilated façade elements for the renovation of residential buildings. It embeds a air renewal system with a double flux heat exchanger (SMHRU) allowing to improve indoor air quality while limiting associated thermal losses. Another system based on PCM (LHTES) allows to store energy to cool the associated flat in summer and preheat it in winter.
Project
An innovative, cost-effective, adaptable and industrialized envelope system for new and retrofit building projects, which include cladding-full-integrated solar thermal collectors and hydraulic circuit integration;
