The world of construction is subject to growing requirements regarding the quality of buildings. The delivery of an envelope must be accompanied by an EPB certificate. In addition, contractors are requiring levels of performance that are higher than those imposed by the regulation: BREEAM, LEED or passive certifications. These certifications are based on theoretical calculations and do not provide a guarantee of real building performance. However contractors aspire to obtain better guarantees regarding buildings real performance. The increase in the number of airtightness tests performed reflects this concern. In 2014, one out of every three new dwellings is subject to air-tightness measures in the Flemish Region and one in five in the Walloon Region of Belgium. In that context, there is a growing interest in the concept of ‘energy performance contracting’ defined by the European Directive 2012/27/EU as “a contractual arrangement between the beneficiary and the provider of an energy efficiency improvement measure, verified and monitored during the whole term of the contract, where investments (work, supply or service) in that measure are paid for in relation to a contractually agreed level of energy efficiency improvement or other agreed energy performance criterion, such as financial savingsâ€. Being able to confirm that the obligation of result is achievable and achieved, is the new challenge faced by the construction industry. Research institutes want to consolidate sets of achievable reference values for energy performance indicators and to compare them with theoretical predicted values. They also intend to extend their expertise regarding the analysis of data collected by in situ testing. Education institutions that forms architect engineers intend to promote their training in the processing of data collected through building monitoring, as a significant amount of those engineers are involved in the management of building stocks, thereby confronted to large samples of measured data. Universities are ...
