BREEAM UK NC 2018 LCA creditsThe Hitchhiker's Guide to BREEAM UK NC 2018 Life Cycle Credits
A handy guide to LCA and LCC credits in BREEAM UK NC 2018
BREEAM UK NC 2018 is now live, and it constitutes a big change especially for what concerns the Life Cycle-related credits. The Green Guide is dead, long live LCA!
For any construction specialists working with BREEAM UK, the rolling out of the new schemes has caused much stress and credits-induced panic, but we hope our guide will help you make sense of the BREEAM guidelines and embrace the change.
First of all, what do we talk about when we talk about Life Cycle Assessment and Life Cycle Costing credits?
Material credits supported by One Click LCA: LCA, EPDs, and more
These credits aim at reducing the environmental and social impacts of products used in the construction phase, and they follow a life-cycle based approach.
Mat 01 Environmental impacts from construction products – Building life cycle assessment (LCA)
Worth up to 7+3 credits
The goal of this credit is to reduce buildings’ environmental life cycle impacts through conducting Life Cycle Assessment and integrating its outcomes in the design decision-making process.
Mat 02 Environmental impacts from construction products -Environmental Product Declarations (EPD)
Worth 1 credit
The goal of this credit is to encourage the availability of robust and comparable data on the impacts of construction products by
rewarding the specification of products with environmental products declarations
Mat 06 Material efficiency Assessment scope
Worth 1 credit
The goal of this credit is to encourage the reduction of environmental impacts through optimizing the use of materials during all stages of the project.
This version of BREEAM UK has decided to emphasize the weight given to Life Cycle Assessment, which means that the credit potential for Mat 01 LCA is 10 credits. This is a welcome change, as Building Life Cycle Assessment is a reliable method to assess the sustainability of a building through its whole life-cycle, from the extraction of materials to demolition and disposal. If you want to learn more about the Life Cycle Assessment methodology and how it applies to the construction sector, you can find an in-depth guide here.
Moreover, this new version of BREEAM UK encourages designers and builders to select products with an Environmental Product Declaration (EPD). EPDs are a great way to learn about the product’s carbon footprint and other environmental impacts. You can learn more about them by reading our guide here.
Man 02 Life cycle cost and service life planning
Worth up 4 credits
The goal of the credit is to promote the business case for sustainable buildings through the enhanced understanding of capital cost and to improve design, specification, maintenance and operation, by encouraging the use of life-cycle costing.

How to calculate LCA for BREEAM UK NC 2018
In addition to the BREEAM simplified LCA tool, you can calculate the LCA with an approved Building LCA tool. If you only use the BREEAM simplified tool, you will not be able to achieve all the potential credits.
These are the steps required by BREEAM:
- Identify the elements that form the building and are in scope
- Calculate the LCA with a building LCA tool that is recognized by BREEAM (see The Mat 01/02 Results Submission Tool)
- Get the LCA results for the building for the in-scope elements and enter them in the Mat 01/02 Results Submission Tool. In addition to this, enter further information required by the tool including (but not necessarily limited to) construction and product descriptions, quantities, service lives, transportation distances, classifications and justification for design decisions
- Get the credit award building from the Mat 01/02 Results Submission Tool
IMPACT equivalent or IMPACT compliant
One Click LCA has both an IMPACT equivalent and an IMPACT compliant option. You can use either for BREEAM UK NC 2018.
The Impact compliant tool uses the IMPACT database, which is an average UK construction material database licensed by BRE. To enable the IMPACT-compliant module, you need purchase the IMPACT database license.
The IMPACT equivalent tool uses manufacturer specific environmental product declaration (EPD) data from manufacturers who have published their data in BRE EPD system or with some other EPD publisher. There are also differences in the scope of the analysis.
The IMPACT compliant tool calculates all 24 environmental indicators according to EN standards, while the IMPACT equivalent tool focuses on carbon footprint. Both of them are verified for compliancy and both can be used for BREEAM UK NC 2018.
