The new Building Regulations Part O 2021 Edition is the first of its kind and will tackle overheating in new residential type buildings.

Overheating

Approved Document Part O: Overheating

What is Part O?

The goal of Part O is to limit solar gains within summer and provide adequate means of quickly removing excess heat from indoor environments through ventilation.

At Building Compliance Testing we encourage the design and construction of buildings that limit excessive solar gains to ensure compliance with Part O and ensure the end-users have guaranteed comfort and health

Here at Building Compliance Testing we can demonstrate Part O Overheating compliance through Simplified Assessment and TM59 Dynamic Thermal Modelling

An Interdisciplinary Approach

At Building Compliance Testing we not only acknowledge risks of overheating but too take into account air quality, acoustics and ventilation. We specialise in:

    • Part F Ventilation – ensuring an adequate ventilation strategy is designed and implemented to ensure overall compliance.

    • BS8233 and BS4142 Environmental Noise Assessments – In locations where external noise maybe an issue the overheating mitigation strategy should take account of the likelihood of the windows being closed during sleeping hours. Noisy is defined as 40dB LAeq,T over 8 hours ‘2300-0700’ & 55dB LAFmax, more than 10 times a night. It maybe required to have a noise assessment performed to demonstrate these values are not exceeded.

    • Air Quality Assessments – Dwellings near significant local pollution should follow Approved document Part F to reduce the intake of pollutants.
