What do investors need most to improve the decarbonisation of their portfolios?

Heating and cooling demand should increasingly be assessed using dynamic analysis that reflects actual building use, rather than relying solely on conservative, standardised calculations that often result in oversized installations. Systems should be properly sized, simple, robust and energy-efficient, with limited maintenance requirements.’

The best energy is the energy you do not consume, so reducing demand should always come first. However, improvements to the building envelope are not always technically or economically feasible in existing buildings.

Finally, investors need access to capital to turn their decarbonisation ambitions into reality.
