Thermal comfort

Thermal Comfort Assessment

Heat complaints are the most common workplace environmental complaint. A thermal comfort assessment moves the conversation from anecdote to PMV-grade data and a clear remediation path.

  • Air temperature, RH and air speed
  • Mean radiant temperature
  • PMV / PPD calculation per zone
  • BS EN ISO 7730 alignment
  • Adaptive comfort analysis
  • FM-ready action list

What thermal comfort means

Comfort is more than a thermostat reading. PMV combines air temperature, radiant temperature, humidity, air velocity, clothing and activity into a single predicted comfort score per zone — and predicted percentage dissatisfied.

Who this helps

Facility managers, property managers, HR and wellbeing leads, health & safety teams, workplace consultants and building owners handling recurring "too hot / too cold" complaints, glazed-façade overheating, post-refurb commissioning, or BREEAM Hea 04 evidence.

What you receive

Per-zone PMV/PPD scoring, heatmap overlay, root-cause analysis (solar gain, AHU control, perimeter heating, zone-level imbalance), and prioritised remediation: blind upgrades, BMS retuning, perimeter rebalancing, or capital glazing changes.

Frequently asked questions

How long does the survey take?
Typically one to two weeks of monitoring across representative zones.
Can we use this for BREEAM Hea 04?
Yes — the report is structured to drop directly into your BREEAM evidence pack.
Do you cover summer overheating in offices?
Yes — TM52/TM59-style overheating risk assessment is part of our standard offer.
