Abstract

Ireland’s CO2 emissions are above the EU average and follow an increasing trend. Since 64% of Ireland’s 2050 housing stock already exists, this is a prime target for carbon reduction measures. The existing housing stock is typically hollow block masonry construction. HTB2 was used to analyse a representative dwelling in an Irish climate with refurbishment options which increased the building specific mass to 76kg/m2, 361kg/m2 and 603kg/m2 for more than forty patterns of occupancy. For average Irish occupancy, the thermal mass had little impact on energy use. However, heavy weight fabric was more efficient for higher occupancy and light weight fabric more efficient for lower occupancy. High thermal mass increased energy use substantially for dwellings left unoccupied for a full day or more. Thermal mass had a modest impact on overheating. Reduction of internal gains and increasing ventilation at appropriate times were far more effective.
