A building's week has 168 hours. How many is anyone there?

Heating and cooling a building when it's empty is the most common waste we find — usually because a schedule was never set, or was set years ago for different tenants. Pick a building type and see its week.

Occupied hours, week by week

Each row is a day, each square an hour from midnight to midnight. Red squares are hours with people in the building.

Office: Monday to Friday, 7am to 6pm.
Example schedules. Your building's will differ.

55hours occupied

113hours that can be set back

Shown: an office open Monday to Friday, 7am to 6pm.

The counts are simple arithmetic on the example schedule — not a prediction of your energy savings, which depend on the building, the equipment and the weather.

What a good schedule does

Comfortable at 8am, not running at 3am.

Setback when empty
Temperatures allowed to drift overnight and at weekends, within limits that protect the building.
Start early enough
Units start before people arrive so the building is comfortable at opening, not an hour later.
Fresh air only when occupied
Outdoor air is brought in when people are there, not heated and cooled for an empty room.
Holidays set in advance
Closures entered for the year, so a long weekend doesn't run at full comfort.
An override button
Someone working late presses it and gets two hours, then the building goes back to setback.

What we check

The schedule you have, and the one you need.

Thermostat or building controls — the schedule lives in one of them.

What's programmed

Every thermostat or controller, read and written down — including the ones nobody remembers.

What the building does

Your real hours, cleaning crews, deliveries and the one team that works Saturdays.

What we change

A schedule agreed with you, set on every unit, and written into the service report.

Businesses

Where it matters most

Offices, clinics and churches — buildings with clear hours and long empty stretches.

Homes

The same idea at home

A programmable or smart thermostat set to when you're out and asleep. We set it up when we install or service a system.
