New Building Regs 2022 – What’s changed?

New Building Regs 2022 – What’s changed?

Last month saw the introduction of the highly anticipated Building Regulation changes, introduced by the Department for Levelling Up, Homes and Communities. The changes included  updates to Part L and Part F and the introduction of new Approved Documents Part O and Part S.

Why have these changes been introduced?

These changes are aimed at improving the energy efficiency of housing in the UK to help us move towards the 2050 Net Zero Carbon targets. The UK Built Environment (buildings and infrastructure) is reported to be responsible for 25% of total UK greenhouse gas emissions  and so has a big part to play in helping to meet this target.

The new and updated regulations are interim changes on the road to the implementation of the Future Homes Standards planned for 2025, which is targeting a minimum 75% CO2 reduction.

What has changed?

What effect will these changes have?

Approved Document L1A, L1B, L2A & L2B:

Conservation of fuel and power

Updated documents replace previous versions:

Volume 1: Dwellings

Volume 2: Buildings other than Dwellings.

Both now covering new and existing buildings. Meeting primary energy targets is now equally, if not more, important than carbon emission reduction targets.

A new metric; ‘Primary Energy Rate’ has been introduced. CO2 emissions from new build dwellings will achieve a minimum anticipated 30% reduction when compared to the previous regulations.

Buildings other than dwellings are anticipated to reduce emissions by a minimum of 27%.

Approved Document F: Ventilation

Updated documents replace previous versions: Volume 1: Dwellings and Volume 2: Buildings other than Dwellings. The new Approved Documents contain updated minimum ventilation provision by floor area (now including circulation and lobby areas) and introduction of new reporting and commissioning requirements.

Marginal uplift in whole house dwelling ventilation rates, Recirculating systems must meet certain new criteria and air quality sensors are required in a range of spaces.

Introduction of minimum fresh air rate per m², and requirement to ventilate common parts such as corridors and lobbies in commercial buildings.

Approved Document O: Overheating

New Approved Document O provides statutory guidance on overheating mitigation for new dwellings and residential buildings.

The primary objectives are to limit unwanted solar gains in summer and provide adequate means of removing excess heat from the indoor environment.

The majority of developments will be subject to the dynamic thermal modelling approach using CIBSE’s TM59 for regulatory compliance. Blinds should no longer be relied upon for compliance.

Approved Document S: Infrastructure for Electric Vehicle Charging

New approved Document S which provides statutory guidance on infrastructure for electrical vehicle charging.

For residential schemes, generally 100% active provision should be made for car parking spaces served by EVC’s. For non-residential schemes, a minimum  of 10% active provision with a further 20% passive provision for future installation.

What about projects which have started?

The new Building Regulations will not apply where initial notice or full planning application has been submitted to a local authority in respect of that building before 15 June 2022, providing start on site also commences before 15 June 2023.

If either of the above criteria are not met, compliance with the new regulations will apply.


What future changes are still to come?

Further technical consultations on the Future Home and Future Building Standards are proposed for Spring 2023, with introduction in 2025.

The Future Homes and Future Buildings Standards are a set of standards that will complement the Building Regulations to ensure that new homes built from 2025 will produce 75-80% less carbon emissions than homes delivered under current regulations.

When implemented; existing dwellings may also be impacted, however homeowners will likely only be affected if they are making thermal upgrades or building an extension.

How can we help you?

If you would like to arrange for us to come and speak to you and your team in more detail about how the building regs changes may effect your projects please drop us an email.

Building Services Engineering for Homes

Building Services Engineering for Homes

In recent years we have supported our clients with the delivery of residential accommodation to the value of around £400M, playing a key role in developments for the For Sale, Private Rental, High End, Social and Retirement markets.

As Building Services consultants we focus on using engineering and technology to help create desirable places to live which meet the needs and expectations of residents. Our track record in this sector provides us with a knowledge of the key drivers but equally we recognise the need to continually respond to market changes especially as the need for more new homes in the UK increases.

We understand the balance of development deliverables and financial viability and achieve this by always seeking the optimum design.


Environmental Sustainability

Our approach to sustainability is to follow the Energy Hierarchy, which encourages the inclusion of energy efficient design features throughout the development to minimise both the carbon and environmental footprint and to meet sustainable standards set by Clients, Planning & Building Regulations.

Our strategy embraces a Lean, Mean and Green approach through the use of advanced building modelling software and passive design techniques such as improving building fabric elements and air tightness criteria beyond the level required to comply with the Building Regulations.

We incorporate high-efficiency systems and effective controls throughout the design such as, gas fired condensing boilers to provide both hot water and heating with an efficiency of up to 98% and energy efficient LED lighting where practicable. Mechanical ventilation systems which include heat recovery and low specific fan powers are specified in order to keep costs to a minimum whilst maintaining high level of energy efficiency.

Renewable energy sources such as photovoltaic panels and/or solar thermal are incorporated where possible to achieve CO2 targets or provide desirable benefits.

Overheating in Homes

Rising environmental temperatures, changes in building types, the drive towards energy efficiency and poor installation practice all contribute towards overheating issues in homes. These issues alongside the ever increasing demand for new homes increases the need for improved design solutions to counter overheating.

As Building Services Engineering consultants we are involved in an increasing number of high and low rise residential schemes where it is our responsibility to help clients find the appropriate design solutions to mitigate or control overheating.

Using the latest BRE approved dynamic simulation modelling software to ensure compliance with the latest regulations and relevant standards we build and carry out detailed thermal modelling analysis to assess the risk of overheating.

The thermal model we develop allows us to compare how the various building envelope, shading or ventilation methods compare when limiting overheating. It also factors in site specific constraints such as acoustic restrictions and air quality and can analyse these factors whilst maintaining energy efficiency to comply with Building Regulations.

Post-occupancy Testing and Lessons Learnt

As an organisation, we endeavour to learn from our previous projects through engagement with clients, the design and construction teams, and purchasers and occupiers. Post-occupancy evaluations are regularly undertaken to identify both positive elements from our designs and any areas that could potentially be improved.

This history of interaction with purchasers and occupiers has led to numerous design improvements. These include the use of smart metering and heating controls, which have dramatically improved the building’s environment thus creating better places to live. Also, the installation of electric vehicle charging points, to both encourage low carbon emission transport and to minimise the impact of the development on local air quality.

If you would like any advice from a member of our residential team about an existing or future project please contact Jamie Hall or Sean Duffy.
