Abstract: The paper introduces an innovative, short duration ‘Pulse Test’ variant of a whole house heat loss (‘Co-heating’) test tightly coupled with simulation tools. The method relies on monitoring the heating/cooling inputs and temperatures in each room during a one-week period in order to: a) capture the response of the building to a step-change in heating or cooling, based on a 25-30oC temperature difference against ambient; b) identify the energy inputs required to maintain the elevated/depressed conditions in each room; and c) profile the response of the building during its return to ambient. The data captured is used to calibrate the digital twin, including the impact of internal mass and facade faults as well as the phases of the physical test. The calibrated model can then be used for further design explorations.
