Why empty floors cost more than you think

Hybrid work left offices half full. Most buildings still heat and cool them as if nothing changed.

Empty open-plan office floor with large windows

In short

Schedules still assume five office days a week

Badge and booking data show where people really are

Empty zones drift gently inside the comfort band

Walk through most offices on a Friday and the pattern is hard to miss.

Whole floors were lit, heated and ventilated for nobody.

The schedule is the problem

Building systems run on schedules set when everyone came in five days a week. Occupancy has changed. The schedules mostly have not.

Badge data, room bookings and Wi-Fi counts already tell you where people are. Ohmwood reads those signals and lets empty zones drift gently inside their comfort band.

What it adds up to

Across our portfolio customers, floors with under 20 percent occupancy now use about 40 percent less energy than they did before tuning, with no change for the people who do come in.
