Whole Life Cycle Assessments (WLC or LCA)

The process of constructing, renovating and demolishing our buildings creates more carbon than all the years we spend occupying them. But today’s Building Regulations ignore this significant impact on the environment.

How Energist can help

Whole Life Cycle Assessments (WLC or LCA) predict the total carbon emissions of a building over its lifetime, including the emissions used to create it and recycle it. This modelling technique is also known as the embodied energy or the carbon footprint.

All key building components are considered in this assessment, from the cement between the bricks to the bedroom skirting boards. The calculation considers the amount of CO2 used to produce each material, transport to site and the impact of recycling it.

WLC is now a mandatory planning condition for all major developments in London. This was introduced when the London Plan was updated in 2021, although some local authorities had been requesting this prior to it being rolled out across the capital.

For construction projects that require a BREEAM rating, an LCA report has been a mandatory requirement since 2018.

We are also working with developers who have opted to complete lifecycle assessments voluntarily to help them source materials with lower carbon footprints for their future developments.

Typically, there are three stages to the life cycle assessment. A pre-planning edition covers the proposed principles which will be adopted on site. A second phase includes full modelling of the carbon emissions across the development, including options for improving the results. A third, post-construction version provides results using project specific construction data and compares these results against a target.
