Knowledge Transfer Partnership (KTP) – Revision of the CIBSE weather files
(30 months, start date April 2022). CIBSE, in collaboration with the University of Exeter, has secured Innovate UK funding to revise the CIBSE weather files. Dr Hailun Xie has been appointed as the KTP Associate. Work on the project started in April 2022.
Embodied carbon of building services.
A collaboration with Elementa Consulting, part of Introba Group, developed the methodology for TM65, published in January 2021. We continue to work with Introba to facilitate data collection, working with various MEP manufacturers to help build embodied carbon datasets and set a UK standard methodology for calculating embodied carbon of MEP products and systems when Environmental Product Declarations are not available.
The TM65 methodology is quickly becoming an industry standard and is being adopted by practitioners, manufacturers and to support policy. We also published two supplements to TM65:
-
-
- Embodied carbon in building services: Using the TM65 methodology outside the UK
- Embodied carbon in building services: A calculation methodology for Australia and New Zealand
- Further guidance has been published as TM65.1: Embodied carbon of residential heating systems (published), and TM65.2: Embodied carbon of HVAC in offices is due to be published shortly, as applications of the TM65 methodology. A further collaboration with Introba and Amazon is currently developing 4: Embodied Carbon of MEP and MHE systems in logistics buildings.

Daylight calculations in BS EN 17037 (Sept 2020 – June 2022, BRE)
The project provides detailed guidance on how to carry out the new daylight design methods in the new standard BS EN17037 'Daylight in buildings' (ref 1), including identifying which method to use, setting up calculation grids, ground planes and computational parameters, and selecting weather data. The final report, currently prepared for publication, provides clarity for CIBSE/SLL members involved in modelling daylight in buildings.
Determination of Acoustic characteristics of alternative ventilation ducts (2019 – 2023, London South Bank University). The project aims to determine the acoustic characteristics of alternative ventilation ducts used in residential ventilation systems and embed new guidance within CIBSE resources such as Guide B4.
Investigation into the role of ventilation design and operation on the ingress of nitrogen dioxide (NO2) (and particulate matter (PM)) in city centre offices (2021 – 2024, University College London, ARUP and Cundall).
The project has carried out monitoring in UK offices to investigate the causes of ambient air pollution ingress and develop mitigation strategies to control NO2. This project's guidance will better inform how building operation and ventilation practices influence indoor concentration of NO2 and other pollutants. Emma Gibbons, the lead researcher, submitted a paper and presented the project findings at the 2022 CIBSE Technical Symposium.
Energy benchmarks
(July 2015 – ongoing, University College London). The energy benchmarking tool is an online platform which uses energy data, as it becomes available, to provide relevant and reliable benchmarks that represent the current trends of energy use in buildings. The energy benchmarking tool can be accessed here.
