Thermal Comfort (T01) Precondition Flashcards

1
Q

What the aim for Thermal Comfort?

A

to create indoor thermal environments that provide comfortable thermal conditions to the majority of people in support of their health, well-being and productivity.

Achieving thermal satisfaction among people requires some level of control over thermal comfort parameters in any given environment

Q

What 6 core parameters are used to provide a means of predicting thermal comfort?

A
  1. air temp
  2. humidity
  3. air movement
  4. mean radiant temp of surrounding surfaces
  5. metabolic rate
  6. clothing insulation

Q

For long-term thermal data, the project must meet the following monitoring requirements for temperature and humidity:

What is the range for dry bulb temp?

T01 Thermal Performance - Option 2

A

a. meet feature T06: Thermal Comfort Monitoring
b. in the past 6 months, data should use:
1. PMV in range of option 1 using only dry bulb temp
2. dry bulb temp range: 70-77 °F for at least 90% of standard occupied hrs. The designed air velocity is not more 40 fpm at 5.6 ft above the floor.
