Technical Booklet F2- Conservation of Fuel and Power in Non-Dwellings
Technical Booklet F2 from the Department of Finance and Personnel highlights the performance standards for energy efficiency compliance of new and existing buildings other than dwellings.
The National Calculation Methodology used for the compliance of buildings other than dwellings include either Simplified Building Energy Modelling (SBEM) or Dynamic Simulation Modelling (DSM).
New Buildings, Part F2 Compliance
As with new dwellings in Northern Ireland, the main compliance target for new buildings is carbon dioxide emissions. A new building has to achieve a Building Emission Rate (BER) equal to or lower than the Target Emission Rate (TER) established before the building is constructed, in order to comply.
SBEM or DSM calculations are used to calculate the energy performance of a building at both 'design' and 'as built' stage, and can establish a TER and BER for compliance.
If the energy calculations comply with Part F2, this will demonstrate that the building has been designed to the appropriate standards and/or has been constructed to the requirements.
Existing Buildings, Part F2 Compliance
Commercial buildings that have large extensions or experience a change of energy status from a conversion, may require energy calculations to comply with Part F2.
For example, Extensions that are greater than 100m2 and account for more than 25% of the total useful floor area of the existing building will require Part F2 SBEM Calculations to comply.
