Improved condensation management in NCC 2022
NCC 2022 builds on the NCC 2019 provisions to further decrease health risks associated with condensation in new homes.
This article outlines the changes in NCC 2022, which impact some of the Verification Methods and Deemed-to-Satisfy (DTS) Provisions.
Condensation management Verification Methods
These Verification Methods (F8V1 of Volume One (2019: FV6) and H4V5 of Volume Two (2019: V2.4.7)) provide flexible approaches to manage condensation in buildings.
Additional details are included to help practitioners complete condensation risk analyses. Specifically, the referenced Design Application Manual AIRAH DA07 provides modelling details that specialists can use to assess condensation risk in a building.
The Verification Methods now includes quantified targets for allowable condensation risk. A Mould Index of 3 (a measure of mould growth potential) must not be exceeded. Learn more
New quantified Performance Requirements
There are new quantified Performance Requirements in NCC 2022.
Quantification of the NCC
One of our initiatives is to increase the competent use of performance, with a focus on building industry’s capability in developing Performance Solutions.
With this in mind, we’ve introduced more quantified Performance Requirements in NCC 2022.
This article explores the new quantified Performance Requirements across the 3 volumes.
Volumes One and Two
In this section, we discuss the quantification in Volumes One and Two of the NCC. These are grouped together as many of methods of quantification carry across both volumes.
Lots of Volume Three is now quantified. We’ve quantified the following topics:
- velocity (B1P2, B2P3, B3P3,B6P2) (2019: BP1.2, BP2.3, BP3.3, BP6.2)
- water efficiency (B1P4, B2P11, B3P2, B6P3, C1P3) (2019: BP1.2, new, BP3.2, BP6.2, CP1.1)
- pressure (B1P5, B2P9, B3P5, B6P1) (2019: BP1.2, BP2.3, BP3.3, BP6.2)
- pressure relief and temperature limitation (B2P5) (2019: BP2.4)
- legionella control (B2P6) (2019: BP2.5)
- fire-fighting flow rate and pressure (B4P1) (2019: BP4.1)
- ventilation (C1P5, C2P4) (2019: CP1.1, CP2.1)
- contamination (C1P6) (2019: CP1.1).
