LETI unveils spec guide

LETI spec guide

The Low Energy Transformation Initiative has published a specification and procurement guide to support lighting and other designers and contractors ‘who are facing the difficult task of trying to reduce embodied carbon without a clear roadmap to follow’.

LETI, formerly known as the London Energy Transformation Initiative, says the guide is intended to support the move to sustainability 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.

Design and construction is a complex process, with many factors, says LETI. There are many processes and issues to consider and until recently embodied carbon has not been a significant factor of consideration.

‘This guide aims to share the collective experience of low embodied carbon project delivery, to provide greater understanding of the barriers and opportunities that exist within the process and raise awareness of some of the techniques that can be employed to reduce the embodied carbon of new construction. In particular the need for greater engagement between all members of the supply chain.

‘When we started our work, we were determined that this procurement guide would offer practical advice that could be applied at different scales of building. We have consulted widely with industry experts to provide their thoughts on how to manage the procurement process and specifications, offering you an approach which we hope you can develop and adopt to your projects.;

The LETI work includes a project embodied carbon reduction roadmap, suggesting how embodied carbon reduction can be brought into the early stages of the design process, as well as learning from the final build. There is guidance on material efficiency and specification, provided in a series of material guides and finally, three case studies, specifically chosen to illustrate the embodied carbon reduction roadmap.

• Remanufacturing Lighting is the subject of a special one-day conference organised by Recolight and taking place on Thursday 27 April 2023 at the Coin Street Conference Centre in London. This CPD-approved event will give you the tools, insights and contacts make a success of luminaire reconditioning and reuse. You’ll learn how to sell the concept of reconditioned lights, develop best practice policies, comply with the standards, set up a testing regime for reused luminaires and remanufacture fittings at scale. The gathering will also give you inspiration from real world projects which prove that remanufacturing can be a success everyone. You’ll also meet key players in the remanufacturing industry  network with specifiers with the power to get your products into projects. See more HERE.
