In order to reduce the energy use of buildings, several countries have put forward more stringent requirements on the energy performance of new and renovated buildings.  Without exception, these buildings are characterised or awarded a label in the design phase.  A theoretical energy use calculated on the basis of building plans and specifications determines the performance category.

 

An important distinction needs to be made, however, between this theoretical energy performance and the actual ‘as-built’ performance. Several studies have shown that these can differ rather significantly.

 

The energy performance of a building is essentially determined by the (1) thermal characteristics of the building envelope, (2) installed services and (3) building usage.  As the latter is not easily predicted nor controlled, the first two are decisive in achieving the envisaged building energy performance, both for new buildings and renovations.  Hence, the thermal performance characterisation of a building envelope represents a crucial first step to bridge the gap between ‘designed’ and ‘as-built’ energy performance of the building.  A common method to evaluate the thermal performance of a building in situ is the co-heating test.

 

This webinar tries to crystallise the current knowledge on the co-heating test, as applied for assessing the thermal characteristics of the building envelope.
