Business Climate Guidance Case Study: Derwent London

How Derwent London targeted net zero emissions for managed buildings

Targeting net zero emissions for buildings under management by focusing on electricity consumption, renewable energy, and new approaches to building/retrofit.

					Low-energy building managed by Derwent London.

Derwent London is committed to driving the transformation of the built environment to achieve a climate-safe future. To achieve this, Derwent London is consistently looking to step up its climate commitments. In 2020 Derwent London committed to be a net zero carbon business by 2030, bringing forward its previous target by 20 years. In June 2020, Derwent London launched its Net Zero Carbon Pathway setting out in detail how it expects to get there. This includes the objective to achieve net zero emissions from its managed properties.

An important way to achieve net zero is to make the managed buildings all-electric. This includes new projects as well as existing assets where practical. 80 Charlotte Street, completed in 2020, is Derwent London’s first all-electric new development complete with air source heat pumps and solar thermal panels which further reduce the building’s requirement for grid electricity. Targets now exist for all new-builds and refurbishments to reach energy objectives. That means every new building must achieve an energy rating of A, and major refurbishments an energy rating of B.
