How Energist can help

On new residential developments, party walls and floors can be constructed in line with specific building practices known as Robust Details. If you stray away from these standard designs, you will have to have a building tested to ensure acoustic performance meets targets imposed under Building Regulations.

Acoustic Testing may also be required to achieve credits in BREEAM or Code for Sustainable Homes Assessments. If you are building detached dwellings, Acoustic Testing will not be required as there are no Building Regulation targets.

Building a hotel, care home or school?

These buildings require specific acoustic requirements, however most other buildings are exempt, such as detached dwellings which have no acoustic targets. Our team can review your plans and planning conditions to confirm whether testing is required on your development.

  • Building Regulations require a proportion of new homes and non-residential buildings to be tested for Air Leakage Testing. The test is designed to confirm the results in SAP or SBEM Calculations by showing that the more airtight a building is, the more energy efficient it will be.
  • For planning applications made before 2015, Code for Sustainable Homes may still be required as part of legacy planning conditions.
  • Many Local Planning Authorities now request a BREEAM Assessment to ensure a building is constructed to a high standard.

How Energist can help

BREEAM (the Building Research Establishment Environmental Assessment Method) is a credits-based sustainability assessment for non-domestic buildings and potentially residential refurbishment. It is usually requested by your Local Planning Authority, most commonly in city developments, although it can also be adopted voluntarily or as part of funding agreements.

The assessment follows your project from concept design through to construction, completion and into the first year of occupancy. To make sure you don’t miss out on crucial early stage credits, it is important to gather all evidence needed and begin your BREEAM assessment as soon as possible.

How Energist can help

When a Non-domestic building is offered for sale or rent, whether that is a shop, office, factory or hotel, an Energy Performance Certificate (EPC) will be required. This document and supplementary report presents the predicted energy efficiency of the building and offers advice on how this can be improved.

New buildings require an EPC at the point of handover, and anything built in the last ten years should already possess one, but for existing buildings a site inspection is required. If you have several buildings, we can complete multiple site inspections in one visit.

Following the site visit, our SBEM Assessors will issue your certificate within a week of the site survey and should your EPC fall into the bottom two energy efficiency categories (F or G), we will offer the most viable renovation solutions to meet compliance with MEES (Minimum Energy Efficiency Standards).

Variations or breaks in insulation can cause cold spots, which can lead to internal condensation and mould growth. Building Regulations aim to adequately protect buildings from both interstitial and surface condensation through calculations and risk analysis based on the design drawings, however if you are working to a bespoke construction or are constructing a basement, your design will likely need additional checks to ensure condensation isn’t going to be a problem.

Surface condensation can occur where reduced levels of insulation create a cold point on a particular wall, roof or floor. Interstitial condensation can occur where vapour can build up within a construction with no means of escaping. You would usually only complete these calculations if there is a perceived risk based on the design drawings.

Condensation Risk Analysis is completed as part of the detailed design to ensure the proposed building junctions are designed to limit the risk of condensation forming.

With multiple legislative and planning policy requirements governing ecology, it is vital that developers address these concerns as early as possible in the design process.

An Ecology Assessment can be submitted to planners, and if appropriate to your Code for Sustainable Homes or BREEAM assessors, detailing the ecological value of the land. Depending on the sensitivities of the site you may need to prove the ecological value will be no worse following construction, and in some cases, that there will also be an overall environmental improvement. The assessment should also show where the Suitably Qualified Ecologist (SQE) has recommended ecological improvements. This is done through a site survey, which is followed up with a detailed report.

How Energist can help

Many local authorities are keen to encourage developers to be more energy efficient by going above and beyond the requirements of current Building Regulations. Energy Statements are often required by local authorities to demonstrate how local planning policy will be met through a mix of fabric improvements, renewable technologies and heating networks. Forming part of a development’s planning conditions, the report will need to be produced to support the planning application.

Developers will need to commit to carrying out the construction based on the improved design as shown in the Energy Statement. Some planning departments may ask for post-construction checks to ensure the Energy Statement recommendations have been followed.

Our team understands that it’s essential to make sure the Energy Statement strikes the perfect balance between meeting the requirements of planners and not over-committing you with a costly and unrealistic specification.

As part of Part L Building Regulations in England, developers are required to provide handover documentation to the first occupants of a new home. One way of achieving this is to have a Home User Guide (HUG) produced. The document acts as an information pack that includes:

  • An overview of the house construction
  • Where you’ll find fuse boxes and meters
  • How the boiler works
  • The best way to set up your boiler to reduce fuel bills
  • Information about local transport links, shops and health centres.

If your development has an existing Code for Sustainable Homes (CSH) requirement, you can earn useful credits by having a Home User Guide created. Alternatively, a bespoke HUG can be produced voluntarily to match your own style and preferences.

Whole Life Cycle Assessments (WLC or LCA) predict the total carbon emissions of a building over its lifetime, including the emissions used to create it and recycle it. This modelling technique is also known as the embodied energy or the carbon footprint.

All key building components are considered in this assessment, from the cement between the bricks to the bedroom skirting boards. The calculation considers the amount of CO2 used to produce each material, transport to site and the impact of recycling it.

WLC is now a mandatory planning condition for all major developments in London. This was introduced when the London Plan was updated in 2021, although some local authorities had been requesting this prior to it being rolled out across the capital.

For construction projects that require a BREEAM rating, an LCA report has been a mandatory requirement since 2018.

We are also working with developers who have opted to complete lifecycle assessments voluntarily to help them source materials with lower carbon footprints for their future developments.

Typically, there are three stages to the life cycle assessment. A pre-planning edition covers the proposed principles which will be adopted on site. A second phase includes full modelling of the carbon emissions across the development, including options for improving the results. A third, post-construction version provides results using project specific construction data and compares these results against a target.

How can Energist help

SAP calculations are changing.

Stricter targets will be applied to all new developments in England and Wales from June 2022.

The new requirements are expected to include a 31% reduction over the Target Emission Rate, new targets for Primary Energy and EPC ratings, as well as stricter fabric performance targets.

Meeting compliance will require significant changes to the way we build new homes, with the use of low carbon and renewable technologies becoming a standard practice.

SAP is also changing in Scotland, where stricter targets are expected to be enforced from 2023.

Case study

Energist was approached by Spitfire Bespoke Homes to complete the Part L SAP calculations and Part G water efficiency reports for five new five bedroom detached houses in Surrey. Based on the initial specification, the SAP calculations were completed well within the required time frames and were comfortably meeting the required Part L Target Emission Rate. In fact, they were performing 15% better.

However, Aaron Perry from Energist’s Technical Team went the extra mile and reviewed ways of scaling back on the specification, keeping in mind that any changes couldn’t cheapen the look of the homes and couldn’t fall outside the requirements of Part L.

In total, five variations of the SAP models were presented back to Spitfire. Each one ensured compliance with the regulations while offering a cost saving to the builders. These options included a reduction in the amount of wall insulation, alternative window options and changing to a different type of ventilation system.

How Energist can help

The UK has committed to reaching net zero carbon standard by 2050. All sectors of industry need to play their part, and construction is no exception.

Building Regulations will soon be changing to enforce much stricter energy and emission targets on all new houses.

Thicker wall insulation, triple glazing, waste water heat recovery, heat pumps and solar panels are all items that construction companies will need to consider as standard in preparation for these changes.

The first wave of changes will happen in June 2022 when newly registered sites in England and Wales will need to meet the latest requirements. Un-started buildings on existing construction sites will need to fall in line from June 2023. Then, in 2025, a second update to Approved Document L will mean new homes need to be built even closer to a zero energy standard.

Similarly, Section 6 regulations in Scotland are expected to change in 2023.

Energist is known for taking a proactive stance on dealing with new regulations. We are offering in-depth analysis and advice to clients who want to plan ahead and be ready to build on the first day of the new regulations going live.

Our SAP10 Analysis will show how your current specification is likely to fare against the new targets, with options to show how to fully comply with the expected new standards.

This service is available to cover the 2022 / 2023 updates scheduled for England, Wales and Scotland.

Note: This analysis can only be used for development purposes at this time. For AD L compliance you will need to continue using our standard SAP service. Building control bodies will not accept SAP10 analysis as a form of compliance against the current (SAP2012) standard.
