Can the calculation method for the overall transmission and ventilation heat loss coefficients be used for existing buildings?

Yes, but some of the required input data may not be available at reasonable costs. For those cases default values may be provided at national level, e.g. as function of type and age of construction. Question submitted by: Dick van Dijk (...
Ask the Experts

why was the term “heat transfer” introduced instead of “heat loss” in the CEN standards to support the EPBD?

Heat is lost from a building or building part by transmission or ventilation, as a result of a positive temperature difference between the indoor and outdoor (or other) environment. However, if the indoor temperature of the considered...
