Embodied carbon & building services
equipment
Need to reduce carbon emissions
Embodied carbon is becoming more relevant
Potential breakdown between embodied and operational carbon for new buildings over time
Embodied carbon of MEP
?
Embodied carbon of MEP – big quantities
?2000 sqm 25 Tonnes
Embodied carbon of MEP – high impact materials
Embodied carbon of MEP – high replacement rates

Embodied carbon reduction in MEP
design - basics
LESS IS MORE
‘Design out’ MEPReduce overall weight of MEP equipment within a building
Specify equipment with lower weight
THINK CIRCULAR
Specify products and components that can be demounted and reused
products that can be disassembled, and materials recycledEnsure easy access for inspection, maintenance and replacement.
MITIGATE REFRIGERANT LEAKAGE
Specify low GWP refrigerantsReduce overall refrigerant charge
Ensure low leakage ratesEnsure refrigerant is 100% recovered

Environmental Product Declarations
An EPD provides a standard way to disclose environmental impacts about a product throughout its lifecycle, using a consistent methodology
EPDs – where to find them
Go to Section 3 & Appendix A
Context - Need for consistency

CISBE TM 65
Consultant/ researcher using the tool
Step 1: Send the manufacturer the ‘manufacturer form’
Step 2: Receive the ‘manufacturer form’ from the manufacturer
Step 3: Use the ‘calculator tool’ to carry out the calculations
Step 4: Use the results in systems analysis
Step 5: Send the manufacturer form and the completed excel tool (which in effect becomes the reporting form) to CIBSE – to help develop knowledge on embodied and the development of an embodied carbon database.

Manufacturer using the tool
Step 1: Use the ‘calculator tool’ to carry out the calculations (including filling out the disclosure section in the output tab)
Step 2: Print the inputs/ output tabs to PDF - send this to clients/ consultants/ contractors to show the embodied carbon of the product
To help CIBSE develop knowledge on embodied and the development of an embodied carbon database.
Step 3: complete the manufacturer form ( section C and D) and the completed excel tool (which in effect becomes the reporting form) to CIBSE
