Notional & Proposed SAP Calculations
For “Highly Glazed Extensions”
Send us your plans
Send us the floor plans, sections, elevations and specifications of your new extension. Specifications should include details of floors, roofs, walls, windows and doors. Please also include any new primary or secondary heating that may be installed into the extension.
Your Existing Dwelling
We also require details of your existing dwelling. Preferably in plan form with specification details of heat loss floors, walls, roofs and openings . If you’re unable to supply plans and specifications please call for alternative ways we can do the calculations. We also need details of the primary heating system with associated controls, the hot water system with associated controls, any secondary heating, mechanical ventilation, fixed lighting and any renewables.
Part L Assessment
Calculations are done in conjunction with the ‘elemental recipe’ as defined in Appendix R of SAP2012. We model your proposed extension ‘against’ a notional extension of the same size but with 25% glazing and with all components being built to minimum allowable u-values.
Once we’ve completed our assessment we will let you know if your extension is compliant. If it is great, if not we will advise you of the cheapest and least invasive way to achieve compliance.
You will receive a report that will demonstrate to your building control body that the CO2 emissions of your dwelling with the proposed extension are less than the CO2 emissions of your dwelling with the notional extension. subject to any additional specification or remedial improvements (if necessary). In essence this demonstrates Part L1b compliance.
