TN 49: Energy impact of ventilation: estimates for the service and residential sectors.

To quantify the energy impact of air change on total energy use, the AIVC has been conducting a study of current estimates for non-industrial buildings in thirteen major industrialised countries. This document explains how air infiltration and ventilation together account for a significant proportion of energy use in buildings. Air change energy use and its effect on carbon dioxide emissions due to use of fossil fuels are considered. The potential for reduced energy use by improved ventilation control is also reviewed.
