How Energist can help

Air testing regulations in England are changing.

New requirements will include a 100% testing regime for new dwellings, lowering the maximum target to 8, and introducing pulse testing as an alternative method.

The changes will apply to new sites in England and Wales from June 2022.

Our team of Air Leakage Test Engineers cover sites throughout England and Wales and work closely with our Technical Team at Energist HQ to ensure reports are checked and issued on the same day.

Complete solutions from Energist

Air Leakage Testing are one of a host of services that Energist’s Technical Team can help you with. You may also need:

  • For residential dwellings, a SAP Calculation is required to show energy efficiency compliance.
  • For commercial buildings, a SBEM Calculation is required to show energy efficiency compliance.
  • Many Local Planning Authorities now request a BREEAM Assessment to ensure a building is constructed to a high standard.

How Energist can help

The Approved Document for Overheating (AD O) will go live on all new sites in England from June 15th, 2022. A similar document is expected to be launched in Wales shortly.

The design of all new dwellings will need to be checked to make sure there are enough openings to allow for good air flow in summer months, while also checking the amount of windows isn’t excessive to cause high levels of solar gains, as that can lead to uncomfortably hot living conditions.

Targets are stricter for sites built in the centre of our two biggest cities – London and Manchester, and will put particular pressures on designers of heavily glazed blocks of flats, or where dwellings don’t have openable windows on opposing walls.

In these cases, enhanced 3D thermal dynamic modelling will be required to confirm the design is not at risk of overheating.

Developers who wish to avoid such detailed modelling may choose to reduce window sizes, include solar shading or even install external shutters as alternative routes to keeping buildings cool.

Energist’s Technical Team will soon be able to check your current building designs against the proposed new overheating requirements to confirm, with certainty, how they will perform against the new targets.

Why choose Energist?

  • Overheating is not a new discipline for us. Our London Planning team has years of experience producing bespoke 3D modelling and running models in line with the TM59 standard.
  • If the dynamic method sounds a like too big a step initially, we are also providing advice on how to comply with the Simplified Method.
  • We can guide you through the new requirements for AD O in England, and are poised to offer the same level of service in Wales once these separate requirements are confirmed.

Complete solutions from Energist

  • The introduction of an overheating target into Building Regulations is part of a major wave of change in 2022 which will re-shape how we construct our homes and places of work in the UK.
  • The Future Homes Standard policy also includes substantial rewrites to Approved Document L, which will change SAP and SBEM calculations, and also Approved Document F which covers air permeability, ventilation systems and air quality.
  • When Part L was last updated seven years ago, Energist’s Technical Team was proactive in promoting the changes, and offering workshops and seminars to help architects, designers and builders understand the new rules. We’ll be repeating our successes through 2022.
