Embodied and whole life carbon assessment
Delivering a more planet friendly built environment.
We have an opportunity to reduce our carbon impact on the environment through the buildings and spaces we create.
Now we have the ability to quantify those impacts by reducing carbon emissions through better building design, low carbon material choices and circular economic strategies.
This is no longer optional but essential and, with the right advice, achievable.
Why measure embodied carbon?
Understand: Help project teams to understand the overall environmental impact of the building design when specifying construction products and materials.
Quantify: Ability to quantify embodied life cycle greenhouse gas emissions at design stage.
Compare: Ability to directly compare carbon impacts of our projects.
Reduce: Flexibly assess options to reduce carbon impacts at concept stages.
BREEAM: Ability to prepare building life cycle assessment (LCA) for BREEAM credits.
Net Zero: Ability to lead the transition to a net zero carbon built environment, as promoted by the UK Green Building Council (UKGBC).
Transparency: Provide transparent information when calculating building embodied carbon emissions which can be independently verified by clients seeking to reduce their organisation’s carbon footprint.
Building life cycles explained
Stages A1 to A3
Extraction of raw materials (A1)
Transporting raw materials to place of manufacture (A2)
Assembly / Manufacture and packaging at a factory into building products (A3)
These are known as ‘Cradle-to-gate’ emissions.
Stages A4 to A5
Transporting products to site (A4)
Assembly into a completed building (A5)
Combined with previous stages is known as ‘Cradle-to-PC’ emissions (Practical Completion) or are sometimes termed the ‘Upfront’ emissions.
Stages B1 to B7
Use, maintenance, repair, replacement or refurbishment (B1 to B5)
Operational Energy Use (B6)Operational Water Use (B7)
These account for the emissions ‘in use’ following handover and it is standard practice to assess these over a 60 year time frame.
Stages C1 to C4
Deconstruction and demolition (C1)
Transport of waste, processing or disposal (C2 to C4)
Combined with all previous stages these are known as ‘Cradle-to-grave’ emissions.
If Operational Energy B6 and Water Use (B6-B7) are excluded these are known as the ‘Embodied Carbon’ emissions.
BIM enabled LCA calculations
OneClick LCA links to our Revit BIM Model’s volumetric data for accuracy.
We map material choices to the largest LCA Database of generic and local Environmental Product Declarations (EPDs).
All data is continuously verified and up-to-date in a central database.
BRE approved for BREEAM Mat Credits.
Compliant reporting based on the RICS ‘Whole life carbon assessment for the built environment’ which is currently the leading methodology based on EN 15978.
Operational Energy calculation
The Passivhaus Planning Package (PHPP) is used to assess the energy efficiency of a building through the conventions of the Passivhaus standard. We have certified Passivhaus Designers in-house.
We can review all types of building at design stage, preplanning or post planning. The PHPP process will identify the heating and cooling demand per year, as well as the renewable energy demands and gains.
This is an excellent design tool that can be used to optimise performance and give you a good estimate of annual running costs and the carbon impact over the life of the building.
Understanding the Data
We know LCA terminology can be confusing which is why we aim to present data in a visual way to enable project teams an stakeholders to grasp the impacts in a more personal way…
Like an energy label we can benchmark your building against industry standards and best practice for example the RIBA 2030 Climate Challenge and others. With your permission we will actively share our results to further inform emerging standards and future regulations.
