The latest list of approved software for the production of non domestic Energy Performance Certificates (EPCs), Display Energy Certificates (DECs) and Air Conditioning Inspection Reports (ACIRs).
Regulation 24 of the Building Regulations 2010 requires the Secretary of State for Communities and Local Government to approve a National Calculation Methodology (NCM) for calculating the energy performance of buildings.
All software that is used to assess the energy performance of buildings must be validated to ensure that it operates in a manner, and to a standard, consistent with the NCM before it can be approved by the Secretary of State.
In respect of ACIRs the software is approved as fit for commercial use in its current state and form to generate an inspection report.
