[holding answer 10 March 2008]: The competencies required of energy assessors when preparing energy performance certificates are set out in the National Occupational Standards (NOS) published by Asset Skills. They include requirements to make accurate observations and measurements and to carry out calculations using the Government's Standard Assessment Procedure for the Energy Rating of Dwellings, SAP 2005. SAP 2005 takes into account window area and the presence or otherwise of multiple glazing.
