The design of a new teaching block for a primary school in London gave us the opportunity to investigate the carbon emissions of the building. As the air permeability of the block would be unknown until it is tested on its construction, we were asked to simulate the buildings carbon emissions under both an air permeability of 3 m3/(h.m2) and 5 m3/(h.m2).
We were then able to advise the engineers on the project how they could slightly improve their designs in order to still achieve a Part L2 pass, if the building achieved the higher air permeability value.
As well as investigating the carbon emissions of the building, we also produced results for the Overheating, daylighting and natural ventilation rates of the new block. The overheating results were carried out under both BB 101 regulations and TM 52. This was to show that the classrooms would satisfy the BB 101 regulations required by school and also pass the more stringent criteria required by TM 52.
