Experimentations and validations are essential elements of scientific research, especially on studying and improving the energy performance of buildings. Different types of specialized laboratories exist to carry out such experiments, particularly in the Greater Region: the cross-border region extending over Wallonia in Belgium, Grand-Est region in France, Rhineland-Palatinate and Saarland in Germany, and Luxembourg. The equipment of those labs is closely linked to their individual focus on energy performance research and is to date only operable on site. In the framework of the European program Interreg V-A Greater Region, the “RCC/KN” (Climate Chambers Network) project was funded in order to participate to the specific goal of the program consisting in strengthening cross-border cooperation in the field of research in the Greater Region. The aim of the project is to connect laboratories in a network that involves classic aspects of exchanging experiences, practices or researchers but also aims at implementing a remote connection between labs. Here the remote connectivity between laboratories is intended to allow sharing their different equipment based on a messaging platform and the use of emulation techniques. The platform is going to provide real time data exchange to perform remote tests between the connected labs on the network. The connection between the different sites has to be tested in order to continue towards an experimental phase involving the connected laboratory equipment and resources. The present paper aims to describe the development of the messaging platform and to present the first outcomes of preliminary connection tests between involved labs. The potential applications and contributions of the network are described as perspectives of the research. [less ▲]

The Interreg Va Pth4GR²ID project (“Power to Heat For the Greater Region’ Renewables Integration and Development”) focuses on the determination of an optimal solution at a technical, economic and ecological point of view for the use of heat pumps in Greater Region (Wallonia BE, Luxembourg LU, Grand-Est FR, Rhineland-Palatinate and Saarland DE) as storage solution to absorb the part of local renewable electrical production that could not be injected into the grid (because of grid generation congestion risks). The decision to work with this kind of solution is justified because of the important part of total energy consumed in the residential sector for buildings heating. The present paper focuses on the flexibility potential evaluation of two residential buildings in order to evaluate their contribution to the electrical grid management in the Greater Region. The work is based upon simulations which are run with TRNSYS software. The capacity of buildings to deal with a heating system cut-off strategy during winter is assessed by means of comfort and energy performance indicators. The goal of this study is to assess in which way the selected buildings will respond to a heating cut-off (in case of grid congestion, the heat pumps will be switched off) and to analyse their “flexibility” as a function of design parameters series. The flexibility takes into account the comfort and the energy aspect of buildings performance. The first part of this paper presents the method used to select the reference buildings in Wallonia and the second part is dedicated to the evaluation their flexibility according to several heating management scenarios. This evaluation is realized by means of specific performance indicators which were developed the project. [less ▲]
