What is Whole Life Carbon Assessment for Buildings?

Whole life carbon assessments measure the total emissions of a building from material extraction and construction through to operation and eventual demolition. This approach prevents the common mistake of reducing operational energy use while accidentally increasing the carbon footprint of the building materials used. Early adoption of these assessments allows developers to compare structural systems and cladding materials to find the lowest carbon options. In regions like London, these assessments are becoming a mandatory part of the planning process for major developments.

The shift toward embodied carbon is long overdue. Too many projects claim to be green because they have efficient HVAC, but they used massive amounts of high carbon concrete to get there. The real question is whether the cost of low carbon materials is actually manageable for mid sized developers.

That is where the London Plan requirements come in. Once it becomes a planning hurdle, the market for low carbon materials scales and prices usually drop. The issue is standardizing the reporting so developers cannot just cherry pick the data that makes them look best.

Interesting, but I wonder how they are accounting for the grid transition in the operational carbon phase. If the grid cleans up faster than predicted, the operational side drops, making the embodied carbon the only thing that matters. Do these assessments use static or dynamic emission factors?

Basically says we need to look at the whole lifecycle of a building, not just the electric bill. Useful for anyone trying to figure out why embodied carbon is suddenly a huge deal in construction.
