Popis: The certification of Building Energy Performance is currently based on theoretical calculations. However, in a context of growing interest in the concept of ‘energy performance contracting’ as defined by the European Directive 2012/27/EU, the construction industry is facing new challenges regarding the measurement and verification of building real performances. In that context, UCL is developing methods, in collaboration with Jacques Delens s.a., that can be applied on site during the construction phase in order to assess the actual performance of buildings at a moment when it can still be improved to reach the target without entailing over costs. As quasi-stationary co-heating has so far been limited to the winter months, it is crucial to expand the time window for HLC assessment by developing summer approaches. The proposed measurement process includes 9 days monitoring without occupancy. The research implies parallel experiments on identical building units, to check the reliability of a method based the observation of floating indoor temperature compared to a conventional co heating test. The relevancy of the placement of internal insulation on party walls is also checked as it allows the indoor temperature to reach higher values and as it reduces heat losses to neighboring units.
