Operational energy
Use less energy first, then supply what is needed efficiently and, where possible, from renewable sources.
We reduce demand with envelope, shade and daylight, choose efficient systems that suit the use, and plan for renewable energy and for easy operation.
Typical scope
- Efficient envelope and glazing
- Daylight to reduce electric lighting
- Efficient cooling, heating and ventilation
- Controls and metering
- Space for solar and storage where suitable
We do not state performance figures or certifications here. Where a project reports measured performance or holds a certification, it is stated on that project, with its evidence.
