The key information we require is the envelope area (M² of floors, walls & ceiling areas) – together with the proposed Target Emission Rate (TER) for the building – as these are key pieces of data used in calculating the Air Permeability Rate during our Air Test procedure.
These pieces of information will be held in the detailed drawings and the SBEM Calculations – so we would appreciate copies prior to the test being carried out – because dependent upon the complexity of the structure, it may take a considerable amount of time to calculate the envelope area on the test day itself.
