2025 Building Operational Performance Index launched by Demand Logic and Urban Neuron

The Index celebrates buildings that excel across comfort, maintenance, and energy efficiency, offering a roadmap to deliver both sustainability and financial gains. Across central London offices alone, the data identifies £1.43 billion in potential annual economic returns. Globally, the opportunity exceeds £1 trillion, equivalent to eliminating the carbon emissions of all passenger and freight flights worldwide
