Specialists in overglazed extension calculations
Due to increased heat loss through glazing as opposed to insulated walls or roofs there are restrictions in the building regulations to the area of glazing permissible within an extension. Our calculations will show that through improvements elsewhere within the dwelling that the CO2 emissions of your proposed extension are less than a Building Regulations compliant extension
At E & S Bristol we have provided calculations for building control approval on a wide variety of residential extensions including basement excavations, pool houses, orangeries and conservatories open to the dwelling.
Irrespective of the amount of glazing, E & S Bristol will you propose a workable solution in line with your design
As part of our service we will provide U-Value calculations for all new thermal elements
We will make recommendations to reduce the CO2 emissions associated with the extension and if required the existing dwelling
We will provide notional and proposed SAP calculations along with a summary letter for building control explaining how requirements have been met
