Calculating the Envelope Area for an Air Leakage Test - ATSPACE

Tricky properties sometime require the envelope to be calculated using software. In this case we use Google Sketchup which can accurately calculate all the internal surface areas where the insulation line is. This is called the envelope. It also includes the insulated ground floor area. The envelope is absolutely key for your result as the air flow rate gets dived by the envelope at 50 pascals of pressure to obtain your result in this format (m3/h/m2@50Pa). Envelope too big, the result gets better. Envelope to small the result gets worst. Back of a fag packet calculations need to stop, and bee calculated properly. get int ouch with www.atspaceltd.co.uk
