Despite regulatory enforcement, monitoring of actual energy performance of buildings reveals a significant gap with theoretically designed targets in many cases. This accentuates the need to develop reliable methods that can be applied on site to assess the actual performance of buildings.
The main aim of the international research project 'IEA EBC Annex 71 Building energy performance assessment based on in-situ measurements' was to (further) develop methods that can be used to characterize and assess the actual energy performance of buildings based on on-site measured data of in-use buildings.
BCCA was leader of subtask 4 that investigated to what extent the methodologies can be used in a quality assessment framework. A large survey was performed amongst possible stakeholders on interest and expectations of quality assessment methods based on in-situ measured data.
