Principal Debby Ray on being an editor for London Energy Transformation Initiative’s Climate Emergency Design Guide

On January 27, 2020, the London Energy Transformation Initiative (LETI) has published its Climate Emergency Design Guide, which London studio-based Principal Debby Ray contributed to as an editor over the past year. Comprised of over 1,000 professionals hailing from the architecture, engineering and construction industries, LETI is trailblazing a path for the UK to achieve Net Zero by 2030.


In the free, downloadable document, readers will find approaches, targets and benchmarks developments to use as reference points when building sustainable built environments. Focusing on five main aspects—operational energy, embodied carbon, the future of heat, demand response and data disclosure—the group’s methodology sets requirements for archetypes that include small scale residential, medium to large scale residential, commercial offices and schools.

The volunteer-based group believes that these steps are necessary to combat the global climate crisis. Providing benchmarks for the next decade, the group believes it should take the industry five years to refine their approaches and institute standards into design practices. By 2020, it says that 10 percent of “all new projects that developers and designers are involved in should be designed to meet the requirements set out in this guide.” Project teams that achieve the LETI requirements can register their projects as exemplars.

The LETI guide is complemented by the Embodied Carbon Primer, which provides developers, designers, policymakers and the supply chain with an approach to reduce carbon dioxide emitted during the manufacture, transport and construction of building materials.
