How does Part L product modelling work?

The UK was the first major economy to pass a net zero emissions target into law. With heating and powering homes accounting for 22% of all greenhouse gas emissions in the UK in 2018, it is clear that addressing and improving the energy efficiency of both existing (through holistic retrofit projects) and new build homes is a vital area to consider.

It is much cheaper and easier to build energy efficient, low carbon homes rather than retrofitting existing homes; and to that end an uplift in the standards of Part L: Conservation of Fuel and Power of the Building Regulations (as well as the closely linked Part F: Ventilation and the introduction of Part O: Overheating) will come into force in June 2022.

With June 2022 quickly coming around, time is running out to overhaul the design of your houses to ensure they are compliant with the new Part L of the Building Regulations. The uplift to the regulations requires that new builds have higher levels of thermal performance than ever before. The introduction of an entirely new metric (Primary Energy Rate) as well as other changes and additions means that products that enable compliance with the existing Part L regulations may not after the uplift.

So how does Part L product modelling work?

Our product modelling service utilises our SAP 10 Beta version, an early release software that models to the new building regulations.

Using the information provided by the client, we enter the dimensions, construction and building services into the SAP software as normal. This can be based on plans specified by the client, or we can use property archetypes we have in-house. We will also include any additional details that are relevant for SAP 10 that are not in the current version of SAP.

What are the benefits of product modelling?

This allows us to check for compliance against the Building Regulations through the newest version of SAP (SAP 10). This will enable you to:

  • Find out how your products perform against current and future regulations
  • Identify potential improvements
  • Compare your products against your competitors

Determining the performance of your product in new buildings under the upcoming regulations is important, as compliance with Part L often results in design alterations. Ensuring your product gives the best performance for Part L gives you a marketing edge, driving customers to choose your product over those of competitors.
