At Building Regs 4 Plans, we’ve been preparing for the latest changes to the new Part L, set to apply from June (2022). The Government published the Future Buildings Standards consultation document in January 2021. Contained within this document were the interim Part L, Part F and Overheating Regulations for domestic and non-domestic buildings, and the first steps towards the aim to deliver Zero Carbon Ready homes by 2025.
From June 2022, all new homes will be expected to produce 31% less CO2 emissions than is acceptable in the current Part L.
The new proposals include such upgrades as:
- Waste water heating recovery to ALL showers
- Heating systems flow temperature to be NO more than 55° C
- Photovoltaics – proportional to the ground floor area (e.g. 50m² GFA will require 3kW peak solar panels equal to approx. 18m² [assumed to SE/SW orientation])
- Thermal elements U Values of:
- Walls 0.18
- Windows 1.2
- Floor 0.13
- Roof 0.11
The proposals will also encourage the installation of ground source heat pumps which will allow solar panels to be removed from the design and enable greater flexibility in the specified U-Values of the individual thermal elements.
The new Part L was published in December 2021 with an implementation date of June 2022. Developers must submit their Building Notices, Initial Notices or deposit their Full Plans application by June 2022 or comply with the new regulations set out in Approved Document L 2021.
