LETI Specification and Procurement Guide

This guide has been created to support designers and Contractors who are facing the difficult task of trying to reduce embodied carbon without a clear roadmap to follow.

The Low Embodied Carbon Specification and Procurement guide is intended to support that process by considering specification and procurement in more detail, thereby helping to reduce the embodied carbon performance gap between the design intent and the reality of construction. This follows on and links to the LETI Embodied Carbon Primer, which was created to help designers make embodied carbon reduction strategies on projects.

LETI Unpicker – Retrofit vs Rebuild

In LETI’s most recent publication update, LETI have published a document that provides guidance on how to compare whole life carbon for a retrofit, versus its demolition and rebuild. This document aims to help review whole life carbon comparisons between rebuild and retrofit scenarios, to answer the following question:

Does the whole life carbon assessment and comparison provide a basis for decision on the carbon part of the retrofit versus rebuild argument?

To answer this, the Retrofit vs Rebuild Unpicker helps establish whether the assessment and comparison are as fair and like-for-like as possible, technically robust and transparent.

About LETI

LETI is a voluntary network of over 1,000 built environment professionals, working together to put the UK and the planet on the path to a zero carbon future. Our vision is to understand and clarify what this means in the built environment and develop the actions needed to meet the UK climate change targets.

Our volunteers are made up of developers, engineers, housing associations, architects, planners, academics, sustainability professionals, contractors and facilities managers, with support and input provided by local authorities and other organisations.

Originally the ‘London Energy Transformation Initiative’ (LETI) was established in 2017 to support the transition of the London’s built environment to meet Net Zero Carbon. Since then, LETI has formed as a Community Interest Company and altered our name to become the ‘Low Energy Transformation Initiative’, but predominantly we are known as LETI. This reflects our interest in all UK zero carbon policy and regulation.
