Thermal Comfort (T01) Precondition

Question 1

What the aim for Thermal Comfort?

Answer 1

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

Question 2

Overly warm indoor spaces are linked to what health outcomes?

Answer 2

increases in sick building syndrome symptoms, irregular heart rate, respiratory issues, fatigue and negative mood

Question 3

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

Answer 3

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

PMV = Predicted Mean Vote

Question 4

Mechanically conditioned regularly occupied spaces of at least 90% must meet one of the following thermal comfort conditions threshold:

T01 Thermal Performance - Option 1

Answer 4

PMV range of +/- 0.5

Question 5

Mechanically conditioned regularly occupied spaces of at least 95% must meet one of the following thermal comfort conditions:

T01 Thermal Performance - Option 1

Answer 5

PMV range of +/- 1.0

+ 2 points from T03 and/or T04

Question 6

Naturally conditioned regularly occupied spaces must meet all the following Indoor Operative Temperature conditions if the minimum Prevailing Mean Outdoor Temp [tpma(out)] is 50°F:

T01 Thermal Performance - Option 1

Answer 6

tpma(out) x 0.31 + 47.9°F

Question 7

Naturally conditioned regularly occupied spaces must meet all the following Indoor Operative Temperature conditions if the maximum Prevailing Mean Outdoor Temp [tpma(out)] is 92°F:

T01 Thermal Performance - Option 1

Answer 7

tpma(out) x 0.31 + 60.5°F

Question 8

What is dry bulb temp?

T01 Thermal Performance - Option 2

Answer 8

when a thermometer is openly exposed to the air as it reads the air temp outside (away from moisture and radiation)

Question 9

What is operative temp?

T01 Thermal Performance - Option 2

Answer 9

the average of dry bulb temp and mean radiant temp

Question 10

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

Answer 10

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.

Question 11

Thermal Comfort Survey requirements dictate:

T01 Thermal Performance - Option 3

Answer 11

project must score at least 2 points in Feature T02 Verified Thermal Comfort

Question 12

Describe the two options for monitoring thermal parameters in all spaces except dwelling units.

T01 Thermal Performance - Part 2

Answer 12

option 1: annual testing

option 2: continuous monitoring (must meet Feature T06)

Question 13

What are the pre-approved survey requirements for thermal comfort if there are more than 45 occupants?

T02

T02

Answer 14

80% of those regular occupants responded

Question 15

What are the pre-approved survey requirements for thermal comfort if there are 20 to 45 regular occupants?

T02

Answer 15

15 regular occupants responded
