Building Regulations in England & Parts L, F and O
With the transitional period now over, the updated 2022 Building Regulations Part L, Part F, and the new Part O, became legally enforceable for all new residential projects.
This is the biggest regulatory change the construction sector has seen in the last 40 years and a stepping stone in our transition away from fossil fuel systems toward decarbonised homes and the electrification of heat - and ultimately, the Future Homes Standard. This shift will impact the way we design buildings and specify technologies.
Have you decided which technologies to specify to achieve compliance for your next residential project?
The new English Building Regulations came into law on the 15th of June 2021. For projects with existing planning permission there is one year transitional arrangements period that applies on plot-by plot basis.
The updated Part L outlines the four compliance metrics for new developments: primary energy target, carbon emissions target, fabric energy efficiency target, and minimum standards for building fabric and building services.
The ventilation system choice under the updated Part F is linked to aritightness as we look to increase indoor air quality. New Part O offers modelling to help mitigate the risk of overheating in buildings.
We designed a simple guide to the changes to Part L and Part F, and the new Part O, and discuss what they may mean for your project.
Our range of HVAC solutions aim to provide future proof technologies to building projects over various sectors.

How can the Zeroth Energy System overcome the challenges of overheating in large residential developments?
The Zeroth Energy System uses an ambient loop designed to operate at 25oC. This reduces heat losses through the distribution network that could otherwise result in overheating occurring in corridors and communal spaces.
Zeroth Energy System and district heat networks
The tightening timescales for reaching the 2050 net-zero carbon target require us to accelerate our efforts at the decarbonisation of heat. Ambient loop systems, such as the Zeroth Energy System, are being increasingly specified for multi-occupancy developments due to their high efficiency and capability to reduce a building’s CO2 emissions.This raises the question: can the Zeroth Energy System be specified in a district heating priority area, and can it connect to the district heating network?
Will the outcomes of COP26 significantly speed up the uptake of low carbon technologies?
We are all waiting to see what the real impact will be from the climate summit COP26 for the construction sector, specifically with regard to the decarbonisation of heat. One of the insights that came out of the second day of the summit, which featured a session on clean technology and innovation, was delivered by UK Prime Minister, Boris Johnson:
‘By making clean technology the most affordable, accessible and attractive choice, the default go-to in what are currently the most polluting sectors, we can cut emissions right around the world’.
