Operational Carbon Assessment

Model the in-use energy and carbon performance of your building across its lifespan.

What this is

Operational carbon represents the emissions from a building's energy use over its lifetime. We model operational energy demand, carbon intensity of supply, and changes in grid decarbonisation over time, helping you understand the trade-offs between embodied and operational carbon and make informed design decisions.

Why operational carbon matters

Whole-life view

Combine operational and embodied carbon to make balanced design decisions rather than optimising one in isolation.

Grid-aware modelling

We project emissions against future UK grid decarbonisation so today's choices reflect tomorrow's energy mix.

Planning and disclosure

Operational carbon data feeds GLA planning submissions and corporate disclosure requirements.

Lower running costs

Energy reductions identified during design pay back across decades of operation.

Who this is for

Design teams

  • Architects comparing fabric and servicing strategies
  • M&E engineers modelling heating, cooling, and ventilation
  • Sustainability consultants supporting planning submissions

Operators and reporters

  • Asset managers tracking in-use performance
  • Sustainability officers reporting Scope 1 and 2 emissions
  • Developers targeting net zero operational carbon

What you get

  • Operational energy demand modelling
  • Carbon projections over 60-year building lifespan
  • Grid decarbonisation scenario analysis
  • Embodied vs operational carbon trade-off report
