Abstract
Methods and systems for estimating energy loss or controlling ventilation in a building based on measurements of air pressure differences between inside and outside of the building envelope. The measured differences may be used to calculate air leakage and corresponding energy loss, or to control a ventilation system in order to minimize air pressure difference and thereby the energy loss. Energy loss may be calculated by obtaining an estimate of a correspondence between air flow through a building envelope and a difference in air pressure on respective sides of the envelope, obtaining a measurement of a current difference in air pressure on respective sides of the envelope, calculating a current flow of air per unit time through the envelope based on said correspondence and said current difference in air pressure, and providing a representation of the calculated current flow of air per unit time through the envelope.
