CIBSE launch TM65 Embodied carbon in building services: A calculation methodology for Australia and New Zealand (CIBSE TM65ANZ).
The aim is to provide specific detail of alternative assumptions to be made when using CIBSE’s TM65 methodology to calculate the embodied carbon impact of building services equipment when installed in Australia and New Zealand. Many of the methodology’s inherent assumptions in the 2021 publication are specific to the UK.
Building on steps laid out in a companion publication, Embodied carbon in building services: Using the TM65 methodology outside the UK (TM65LA), TM65ANZ provides a methodology to estimate the life cycle embodied carbon of products used in building services engineering where no environmental product declaration (EPD) is available.
Primary authors, Louise Hamot and Clara Bagenal George (Integral Group) said:
“The aim is to create global consistency with relevance locally. The TM65 methodology inherently relies on a set of assumptions that might differ in different countries for supply chain or geographical reasons.
Embodied carbon emissions are expected to grow to represent 85% of Australia’s greenhouse gas emissions by 2050 if no action is taken. Adopting the TM65 methodology in Australia and New Zealand is the first step towards understanding the embodied carbon impact of building services equipment.”
The aim of this local addendum to TM65 is to promote transparency in the building services markets in Australia and New Zealand in relation to embodied carbon, and to provide support for manufacturers looking to take the first steps towards assessing the embodied carbon of products. The CIBSE TM65 methodology provides a simple, replicable assessment methodology that can be completed by researchers, designers and consultants with relatively limited information.
This project was led by the Green Building Council Australia (GBCA) and CIBSE Australia and was facilitated by Integral Group with input from a local working group. The primary authors were Clara Bagenal George and Louise Hamot (Integral Group); Ian van Erden (Northrop/CIBSE Australia); Taryn Cornell (Green Building Council Australia).
