Thermal Comfort (T03 - T09) Flashcards
Thermal control requirements are available to 90% of the regularly occupied space and include -
(T03)
Thermostats within the thermal zone or a digital interface accessible on a computer or phone
Max size of a thermal zone is 650ft or 10 occupants 1 (2) or 320ft or 5 occupants 2 (3)
Temperature sensors are positioned 3.3 ft from exterior walls or any other source of significant heat or cold
All occupants can cool their environment through one of the following -
(T04)
User adjustable thermostat (only in room occupied by one person)
Desk fan or ceiling fan that does not increase the air speed for others
Chair with mechanical cooling system
Other solution capable of affecting PMV change of -.5 within 15 min
All occupants can heat their environment through one of the following -
(T04)
User adjustable thermostat (only in room occupied by one person)
Electric space heater
Heated chair or footwarmers
Blankets (washed weekly)
Other solution capable of affecting PMV change of +.5 within 15 min
50% of the project area is heated with one of the following -
(T05)

Radiant panels cover at least half of the wall or ceiling
50% of the project area is cooled with one of the following -
(T05)
Radiant ceilings, walls, and floors
Radiant panels cover at least half of the wall or ceiling
The project monitors dry-bulb temperature and humidity following these requirements -
(T06)
Sensors are located 3.6-5.6 ft above the floor and at least 3.3ft away form significant sources of heat or cool
One sensor per 3,500ft
Measurements are taken every 15 mins
Sensors comply with WELL device requirements (recalibrated every 3 years and data is submitted annually)
Real-time display of dry-blub temperature and humidity is made available through -
(T06)
Display screen every 3,500ft
A website or app with one sign in every 3,500ft indicating where to access the data
Humidity control is managed through -
T07
Mechanical system has the capability to maintain a humidity between 30% - 60%
Window design may be opened according to the following requirements -
T08
- 70% of the windows may be opened so at least half of the opening is not more than 5.9ft above the floor and 1ft in the smallest dimension. (If heat is present at least 30% operable)
- At least one window is present in each room
- Controls for window operation are not more than 5.6ft above the floor
Instructions for window operation is provided through signage through the following -
(T08)
Windows with low openings are to be used during mild and warm weather
Windows are not to be opened when cooling is in operation
Windows with high openings are to be used in cold weather
The following areas are shaded for more than half of daylight hours -
(T09)
50% of pedestrian pathways and building entrances
25% of parking spaces
25% - 75% of plazas and seating areas
Outdoor areas of congregation are provided with the following -
T09
Highest expected level of thermal perception for each month
Highest measure of thermal perception associated with “moderate” heat stress and at least two counter measures:
- Landscaping, manufactured shading systems, reflectance of surfaces, water features
Dynamic modeling of the building and adjacent buildings takes into account -
T09
Winds do not exceed 11 mph for more than 5% of the year in seating areas or 10% of hours on paths
Winds are not expected to exceed 33 mph on paths for more than .05% of the year
