SAP Calculations for Conversions

If you are converting a building or changing it’s use, you will need to produce SAP Calculations to demonstrate the energy performance of the new dwellings.

Whether you are converting a church or turning a factory into flats, the Part L1b regs require that controlled fittings, services and building materials meet certain efficiency standards, and that the resulting building meets carbon targets.

Performing a SAP Assessment demonstrates to building control, and indeed planners that you are meeting building regulations requirements and local policies, and also provides the means to produce an Energy Performance Certificate (EPC) at the end of the build.

We can help you through the process simply and quickly.

How Does it Work?

BREEAM Assessment

We undertake SAP calculations from existing and proposed plans, and a detailed specification for construction and services. The assessment is carried out from our offices so there is no need to visit site or carry out any surveys.

There are several routes to demonstrate compliance and we will work closely with the client to make this as easy and pain free as possible. The assessment takes place over two stages – design, where we ensure that the proposed design meets the L1b requirements, and as-built, where we issue final reporting and an EPC for any newly created dwellings.

We will ensure that both new and existing elements are up to scratch, identifying how existing walls, floors and roofs may be upgraded and how new features such as heating and insulation should best be integrated.

We work with you right throughout the build process, from start to finish, and we are always on call to provide guidance and advice.

Part L1b SAP Calculations – Experience Counts

Build Energy have extensive experience in dealing with conversion schemes all over the UK and can provide you with all the help you need from concept to completion.

We’ve helped hundreds of architects, contractors and developers in delivering commercially viable, sustainable and environmentally conscious developments. See recent examples on our project pages, like the Hoover Building.

At BE we take a coordinated, joined up approach to guide you through the crucial phases of a build from planning to technical design, and finally completion.We can liaise with your planners and building control departments, understand any particular local requirements, and guide you through.

Recent Projects

"Build Energy were involved from the outset of this new build project. They helped to spec the design in order that the building met the current stringent building regulations requirements for thermal efficiency and water consumption. They performed a pressure test and produced SAP Calculations and Water calculations together with EPC certificates.......their service was prompt, efficient and cost effective......I would have no hesitation in recommending them to others."
