SAP is the Governments Standard Assessment Procedure for Energy Rating of Dwellings.
With the SAP 2005 Methodology now in place and enforced from November 2006, The TER (Target Emissions Rate) vs DER (Dwelling Emissions Rate) Method of Dwelling Energy Compliance will be the only way to achieve Building Control Approval in Relation to Part F - Conservation of fuel and Power 2006 (NI) of the Building Regulations.
Commercial Connections Ltd will offer you a full blown SAP service at design stage and also on completion of the build, but with the expert advice and help of the BRE, our sister company Airtightness Ireland will have the experience and know how of helping you out with the Airtightness Test as well.
Usually extensions can be more complicated to show compliance than a new build dwelling, the software is still usually SAP but the method is different.
Based on Part F1 Building Regulations Northern Ireland, there are 3 main ways of showing compliance for extensions, Commercial Connections only use 2 for simplicity.
STANDARDS BASED APPROACH
(Refer to section 3 of Part F1)
In basic terms this is meeting U-Values in all the various elements of the extension. The starting point should be to take 25% of the floor area of the proposed extension. If your total glazing requirements including windows, roof lights and glazed doors exceed this, then this method can not be used.
EQUIVALENT CARBON APPROACH
This means that we carry out 2 full SAP calculations on the extension including the existing house. For this we would need a full set of plans on the existing house, with information on heating systems, insulation, glazing, ventilation etc. And this also means because the extension has so much glass then the existing house will need to be upgraded in some way to offset.

Part F2 of the Building Regulations Northern Ireland for non-domestic buildings require a unique Target Emission Rate (TER). This TER is the minimum acceptable energy performance established as a mass of Carbon Dioxide (CO2) produced by the building and is given in units of kg/m2 of useful floor area per year. This target is for the provision of heating, hot water, ventilation, cooling and fixed internal lighting for an appropriate selection of standardized activities.
The TER shall be calculated using the Simplified Building Energy Model (SBEM).
SBEM is a lot more complex than a SAP calculation and requires detailed information to be supplied.
