THERMAL COMFORT – WELL v2™: Creating Spaces Where Productivity Thrives

Why Thermal Comfort Matters More Than You Think

Have you ever sat in an office so cold you had to wear a jacket in July?
Or felt so warm in a meeting room that staying awake was a challenge?

That’s not just personal preference—it’s science and performance.

The THERMAL COMFORT concept in WELL v2™ recognizes that temperature, humidity, air movement, and other factors have a direct impact on your health, mood, and productivity.
Research shows:

• Hot environments can reduce performance by up to 15%.
• Cold environments can lower productivity by up to 14%.
• Employees satisfied with their thermal environment are more focused, alert, and motivated.

The WELL v2™ Approach to Thermal Comfort

Thermal comfort is more than setting a thermostat. It’s about creating a holistic, human-centered climate strategy that balances personal preferences with energy efficiency.

WELL v2™ includes nine key features under Thermal Comfort:

1. Thermal Performance (T01)

Design HVAC systems that meet comfort standards using parameters like temperature, humidity, air speed, and radiant temperature.

2. Verified Thermal Comfort (T02)

Survey building occupants at least twice a year to measure satisfaction and take action when targets aren’t met.

3. Thermal Zoning (T03)

Divide spaces into smaller zones with independent controls so each area meets occupant needs.

4. Individual Thermal Control (T04)

Provide personal devices (fans, heaters, cooling chairs) and flexible dress codes to match individual preferences.

5. Radiant Thermal Comfort (T05)

Use radiant heating/cooling systems to improve comfort, reduce drafts, and minimize allergen circulation.

6. Thermal Comfort Monitoring (T06)

Install calibrated sensors to monitor and report temperature and humidity data.

👉 “The Google Nest Thermostat is one of the most efficient solutions for WELL v2™ Thermal Comfort (T01: Thermal Performance & T06: Monitoring). It optimizes HVAC use, reduces energy waste, and ensures occupants experience consistent thermal satisfaction.”

7. Humidity Control (T07)

Maintain relative humidity between 30% and 60% to protect health and comfort.

The Smart Humidifier helps keep relative humidity between 30% and 60%, exactly the range recommended by WELL v2™ (Feature T07: Humidity Control).
By preventing the air from becoming too dry or too humid, it reduces risks of allergies, throat irritation, dry skin, and even supports better sleep and focus.

👉 Perfect for offices, bedrooms, or shared workspaces, this humidifier is quiet, energy-efficient, and adapts to your daily needs.

8. Enhanced Operable Windows (T08)

Design windows with multiple opening modes to optimize fresh air without discomfort.

9. Outdoor Thermal Comfort (T09)

Use shading, vegetation, reflective materials, and wind management to make outdoor spaces usable year-round.
