A competition to mobilise landlords and occupiers around energy performance


Decarbonisation starts with using less energy

Reducing energy usage is the first and most effective step towards low carbon buildings.

Aligning usage and operations deliver the highest return on investment, yielding large gains with minimal costs. It also provides crucial input to better design future upgrade projects.

Operators and occupiers need to work together

Many commercial buildings are still highly wasteful despite design efforts


There is currently no correlation between design (EPC) ratings and actual energy efficiency


Some recently built, low carbon certified buildings show energy use twice above net zero compatible targets

Overall, UK offices use around 250% more energy than achievable best practice






Understand usage

The primary driver of energy performance is aligning building management to user behaviour

Generate improvement ideas

Leverage occupiers’ intimate knowledge of their space

Make an impact

Occupiers are keen to get involved both as individuals and sustainability- minded businesses

YET, historically, cooperation between landlords and occupiers on energy efficiency is difficult...
