SAP Ext At Chantry View
15 Chantry View is an existing property that has been extended under the extruding bedroom on the first floor. What was a sheltered entrance to the garden area is now a beautiful sun lounge, made mostly from glazing.
E2 Consultants were approached to undertake the SAP Extension Calculations to show compliance with the building regulations due to a large amount of glazing.
We produced a 3D model of the building so the surface areas could be extrapolated and used in the calculation. We produced a notional building calculation with the extension built to L1B Standards and the glazing as required.
The glazing was required to be <=25% of the floor area and a proposed estimation was calculated as to find the exact amount of glazing required for the build.
The property shows compliance as the extension is well insulated and has windows of a high enough specification to minimise heat loss through due to the large amount of glazing.
