Operational optimization
Fine-tuning existing technical installations — typically 10–25 % lower consumption without investment.
Most buildings consume more energy than necessary because their systems are out of tune. Operational optimization captures that gap before you invest in new technology.
What we do
- Review setpoints, operating hours and demand control
- Analyse hourly consumption against operating schedules and outdoor temperature
- Align ventilation, heating and cooling with actual use
- Ongoing follow-up with monthly variance reports
When it makes sense
- Buildings with stable consumption that haven’t been reviewed in a few years
- Portfolios with outsourced operations and no clear data ownership
- A first step before larger measures — the savings simplify investment decisions
We don’t deliver a single report and disappear. The impact lasts when the adjustments are maintained over time.
When does it pay off?
Operational optimization usually pays back faster than buying new technology, but some starting points yield particularly large gains:
- Systems that are 3–5 years or older, where the original commissioning and tuning have drifted and setpoints have been changed over time without a consolidated overview
- Buildings that have gone through pandemic periods or other long deviations in use, where operating patterns were never reset to normal operation
- Properties with new tenants, changed usage profiles or refurbishments, where ventilation and heating still operate according to the previous use
- Buildings with documented deviations between projected and measured consumption, or where energy management flags recurring deviations without an obvious cause
- Portfolios where operations are fragmented across multiple providers and no one owns the energy data
Questions and answers
Can we really cut energy use without investing?
Yes. The systems are usually already installed but not tuned for how the building is actually used. Adjusting setpoints, schedules and control sequences typically recovers 10–25% of consumption without capital expenditure.
How much can we save?
For a building that has not been optimised recently, 10–25% is realistic, with the upper end where controls have drifted or were never commissioned properly. Savings are largest in ventilation and heating.
How are the savings verified?
We establish a baseline from metering and EOS/BMS data before the work, then compare actual consumption afterwards, normalised for weather and occupancy — reporting kWh/m² before and after, not just a percentage.
Will the savings last?
Only if the building is kept in tune. We follow up with monthly variance reports rather than delivering a single report and disappearing, so the adjustments are maintained over time.
