Our client wished to add an extension to the rear of their property, however there was a significant amount of glazing in the current design in order to reduce energy bills.
What we did
As the existing dwelling was built in the late 1960’s, we assessed the impact of three potential changes on the existing dwelling’s SAP score:
The final enlarged dwelling had the extension as designed, with some minor adjustments to the fabric where necessary to meet the requirements, and the customer decided they would implement all three changes to the existing dwelling.
The extension calculations produced showed that incorporating these changes meant that the CO2 emissions of the dwelling reduced by a third.
