Evaluation of the Space Heating Calculations within the Irish Dwelling Energy Assessment Procedure Using Sensor Measurements from Residential Homes

Abstract

Abstract The monitoring phase of the SERVE project (March 2011 to July 2013) collated hourly and sub-hourly measurements of room temperatures and separate space heating durations over two full heating seasons, in up to 67 retrofitted dwellings in Ireland. Individual heating patterns and actual heated-period room temperatures are identified and compared to Ireland's Building Energy Rating (BER) model, the Dwelling Energy Assessment Procedure (DEAP), concluding that, following technical upgrades, DEAP over-estimated heating schedules and room temperatures by up to 37% and 1 °C respectively.
