Heatwave Workplace Checklist

UK offices don’t stop working when temperatures rise, but the way people experience the space often changes noticeably.

Heat influences concentration, movement, and how different areas of a workplace are actually used throughout the day.

This checklist is designed as a simple reference point for reviewing how your workspace performs during warmer periods, based on what we see across offices and commercial environments at Sygnus.

No major assumptions, no complex models — just practical things worth noticing when the weather starts to expose how a space behaves.

1. Layout and zoning

• Are people naturally migrating to certain areas of the office during warmer days?
• Do some spaces become noticeably underused in the afternoon?
• Is there enough variation in working zones (quiet, collaborative, informal)?
• Are high-traffic areas unintentionally trapping heat or congestion?

2. Airflow and environmental comfort

• Can air circulate freely through key working areas?
• Are meeting rooms noticeably warmer than open spaces?
• Are windows, blinds, or ventilation being used effectively throughout the day?
• Are there parts of the office that consistently feel uncomfortable regardless of occupancy?

3. Light and heat exposure

• Are desks positioned in direct sunlight for long periods?
• Are screens or workstations affected by glare during peak hours?
• Does natural light improve comfort in some areas but create issues in others?
• Are there simple shading or repositioning opportunities being overlooked?

4. Furniture and usage patterns

• Are people moving furniture or relocating themselves to cope with heat?
• Do breakout spaces remain usable during warmer periods?
• Is seating supporting longer periods of focus in changing conditions?
• Are underused areas a layout issue rather than a capacity issue?

5. Acoustics and behaviour shifts

• Does the office become noisier when windows or doors are open?
• Are people clustering into fewer spaces during hot weather?
• Do acoustic issues become more noticeable when the environment changes?
• Are pods or enclosed spaces being used more heavily during heatwaves?

6. General observations

• Are working patterns changing noticeably during warm spells?
• Does the office still function as intended under different seasonal conditions?
• Are there areas that consistently perform better regardless of weather?

Most offices are designed around “normal conditions”, but workplaces rarely operate in normal conditions all year round.

Heatwaves tend to reveal how a space actually performs, not just how it looks on a plan.

Small adjustments often make a noticeable difference when they are based on how people already use the space, rather than starting from scratch.
