Simplified determination of air infiltration of the citizen as an energy manager.

Presents and explains derivation of simplified heat transfer equation as part of an averaging method to enable perceptive home owner to determine air infiltration. A winter month isselected and the gas meter read daily. Explains how with these minimum data and summary data from us weather bureau average infiltration for the month, plus other useful data such as relative magnitude of conduction vs. infiltration losses can be determined. Demonstrates technique by worked example for a demonstration house. States technique should enable home owners to determine value of extra insulation, draught sealing etc.
