Influence of Building Mass on Energy Consumption
Using computer simulation, the influence of building mass has been studied in a single family house, a unit in an apartment building and a two storey town house. Building mass affects heating energy requirements, the peak heating power demand, the rate of cooling and internal temperatures in summer. Increasing the building mass reduces heating energy requirements from 3 to 10% in a single family and in a two storey town house. For an apartment the reduction was from 1 to 4%. The range of savings is mainly a result of varying the orientation and size of windows and the building location. If the heating equipment is sized accurately building mass reduces the required heating capacity by about 10%. If the heating suddenly breaks down, a heavy building cools down more slowly than a light building. Building mass also lowers excess summer temperatures by storing excess energy in building components. This prevents an unpleasant high rise in inside temperature which can occur in light buildings. Airing the building at night will remove the excess energy stored in the building mass. (ERA citation 08:005497)
