UK Building Compliance carry out SAP Calculations for clients all over the UK. The SAP Calculation allows our technicians to produce a final EPC. Whether you have a single property or a development, our technicians can offer guidance and advice to help you achieve your desired Energy Rating.
One of our most recent projects is a development of Luxury Energy Efficient Homes in the small village of Barton-in-the-Beans, Leicestershire. We were asked to carry out SAP Calculations on 6 detached properties. Once completed, our technicians provided the customer with the predicted EPC ratings.
Predicted EPC’s (otherwise known as a PEPC or Predicted Energy Performance Certificate) are produced during design stage. They show clients and building control what the final EPC rating will be based on the design. To improve an EPC rating, there are often simple and cost effective changes that can be made during the design stage.
When the building is complete, our technicians will confirm specifications and a final EPC will be produced.
Green Print Homes obtained planning permission in August 2016 and instructed UKBC to complete the SAP Calculations and the Predicted Energy Assessment on all 6 detached homes.
Green Print Homes build luxury, A Rated Performance Certificate Houses. The specifications they included in their designs are chosen to ensure their customer purchase a high quality and well thought out property.
A 3D model of the building was created using google sketch up. We use a specialist software package (SAP 2012) to produce the required reports.
To reach an A Energy Rating, a property must reach a score of 92 or above.
Mo, one of our Senior Technicians, completed the SAP Calculations on all 6 properties within 5 days of instruction. The Predicted Energy Assessments were as follows.
|Plot Number||Provisional EPC Score||Provisional Energy Rating|
There were a number of factors which helped Green Print Homes reach such a high rating including:
- Air Source Heat Pumps
- High/robust construction details
- High performance insulation
- Solar PV
Two of the properties didn’t quite reach the required provision A Energy Rating but UKBC made some suggestions to improve these, such as:
- Improve Thermal Bridging Junctions
- Improve efficiency of heating system
When the development is complete we’ll add a link so you can see the final EPC and pictures of the development.
