We are qualified, licenced Part L energy assessors and can provide SAP calculations and Building Control compliance reports for change of use projects, refurbishments and residential extensions. We advise clients on compliance helping to find the most suitable and cost effective means to meet Part L1B of the Building Regulations. Once complete we provide the EPC and As Built documentation. Examples of some of our SAP Part L1B work can be found here.
Blewburton assisted in submitting the required Part L1B paperwork and report to Building Control and the project is a good example of the benefits of engaging a SAP assessor trained in this area of the Building Regulations, an area of strong expertise at Blewburton Limited.
Blewburton modelled a representative sample of units in SAP and SBEM software to develop a picture of the 71-flat site’s performance. This allowed the design team to settle on a cost effective and efficient construction.
This project was one of the first in the country to complete certification against the newly created BREEAM Domestic Refurbishment Scheme.
For this proposed extension, the local Building Control Department wanted to be sure that the carbon emissions from the remodelled house would not exceed current emissions. Blewburton Limited performed SAP calculations using NHER software to ensure compliance.
