The Nightmare

Three common problems were happening at the same time: fixed HVAC schedules, limited visibility of how the office was actually used, and rising energy costs.

The office had changed, but the HVAC schedule had not.

The company was operating in a hybrid-work reality, but heating, cooling and ventilation were still running around static assumptions. Some areas were underused, while energy was still being consumed as if the office was fully occupied.

Every week was the same: energy costs stayed high, utilisation was unclear, and the team had limited evidence to make confident operational decisions.

In Their Words

DIREK® has provided valuable insights on improving space utilisation based on the data provided which will ultimately provide financial and environmental savings.

The DIREK Fix

DIREK deployed smart sensors across the office and connected the data to the D-XPERT® smart building platform. The goal was simple: understand how the workplace was really being used, then use that evidence to optimise HVAC schedules, energy performance and space planning.

The solution combined real-time occupancy monitoring, AI-powered recommendations and BMS integration to move the building away from static schedules and towards demand-led operation.

1. Real-time occupancy tracking

The usage of the entire 1,322 m² office space was monitored.

2. HVAC connected to real demand

Occupancy data informed heating and cooling schedules.

3. AI-powered recommendations

D-XPERT® improved space planning for hybrid work.

4. Energy spike alerts

The platform helped flag abnormal energy behaviour and potential comfort issues.

5. Built to scale

The approach can start with one office area, expand to full coverage, then roll out across more sites.

For the first time, HVAC decisions were based on live workplace evidence — not assumptions, fixed schedules or outdated usage patterns.

Results That Redefine ROI
