Monitor and effectively address unacceptable thermal comfort conditions and inform building managers and users of the thermal comfort parameters of their indoor environment.
Monitor Thermal Environment (1 point)
Projects monitor dry-bulb temperature, relative humidity, air speed and mean radiant temperature in regularly occupied areas within the building, satisfying the following requirements:
Measurements are taken in occupied zones at least 1 m [3.3 ft] away from exterior walls, doors, direct sunlight, air supply/exhausts, mechanical fans, heaters or any other significant source of heat or cold.
The sensor placement density is minimum one per floor or one every 325 m2 [3,500 ft2], whichever is more stringent.
Measurements are taken at intervals and heights specified in the table below:
Parameter Sampling Interval Sampling Height Above the Floor Dry-bulb temperature 10 minutes or less
1.1–1.7 m [3.6–5.6 ft]
Relative humidity 10 minutes or less 1.1–1.7 m [3.6–5.6 ft] Air speed (only if elevated air speed is used) 3 months or less 1.1–1.7 m [3.6–5.6 ft] Mean radiant temperature 3 months or less 1.1–1.7 m [3.6–5.6 ft]
Data are analyzed for regularly occupied hours (e.g., median, mean, 75th and 95th percentile) and annually submitted through WELL Online.
Dry-bulb temperature and relative humidity sensors are recalibrated or replaced annually and certificates attesting their calibration or replacement are annually submitted through WELL Online. Air speed and mean radiant temperature sensors used for quarterly measurements are calibrated as per manufacturer's specification.
Real-time display of dry-bulb temperature and relative humidity is made available to occupants through one of the following:
At least one monitor screen prominently positioned at the height of 1.1–1.7 m [3.6–5.6 ft] per 930 m² [10,000 ft²] of regularly occupied space.
A website or phone application. At least one visible sign is positioned per 930 m² [10,000 ft²] of regularly occupied space indicating the website or phone application where the data may be accessed.
