The aim of this paper was to research the effects of varying treated floor area (TFA) sizes on energy use of a given building. This was done by using excel based software. To reach the aim, five simple buildings with varying floorspace were designed, each with proportionately similar geometry, shape and components.
The result was a clear indication of decreasing space heating energy use over the span of the five buildings with the thermal envelope being the greatest contributor to the decrease in energy use.
The results would suggest that there is not a need to design the thermal envelope of buildings of smaller TFA’s the same way the thermal envelope of buildings with larger TFA’s are designed. There is also a lot of stress put on the U values (and their low values) when designing buildings. The results might beg the question, as designing programs advance, could U-value regulations be laxed and final energy use be pressured in the designing phase. This would mean that there could be savings on material consumption as there would not be a need for such intense thermal envelopes and then also energy savings in the summer as cooling demands would be lower.
