METEOROLOGY – URFACE TEMPERATURE & THERMAL COMFORT CALCULATOR
Standard Effective Temperature
A precise tool.
What is the Standard Effective Temperature & How does it work?
The Standard Effective Temperature (SET) is a measure that combines air temperature, humidity, and radiant heat to assess the thermal comfort of an environment. It helps in understanding how different environmental factors affect human thermal perception.
The formula for SET takes into account the metabolic rate, clothing insulation, air velocity, and other parameters to provide a comprehensive assessment of thermal comfort. The calculation is essential for designing buildings, workplaces, and public spaces that maintain comfortable conditions for occupants.
SET = T_a + 0.35 times (V_a^{0.67} – V_a) + 4.28 times I_c – 1.7 times M_r
T_a = Air temperature in Celsius
V_a = Air velocity in m/s
I_c = Clothing insulation in clo
M_r = Metabolic rate in W/m²
V_a = Air velocity in m/s
I_c = Clothing insulation in clo
M_r = Metabolic rate in W/m²

Frequently Asked Questions
What is Standard Effective Temperature (SET)?
Standard Effective Temperature is a measure that combines air temperature, humidity, radiant heat, and other factors to assess thermal comfort in an environment.
How does SET differ from just measuring air temperature?
SET takes into account additional factors such as humidity, radiant heat, metabolic rate, clothing insulation, and air velocity to provide a more comprehensive assessment of thermal comfort than just air temperature.
Why is the Standard Effective Temperature important in building design?
The Standard Effective Temperature is crucial for designing buildings that maintain thermal comfort for occupants by considering all relevant environmental factors affecting human perception of heat and cold.
Can SET be used to determine appropriate clothing insulation levels?
Yes, SET helps in determining the appropriate level of clothing insulation needed based on environmental conditions to ensure thermal comfort.
How does air velocity affect the Standard Effective Temperature calculation?
Air velocity is a factor in the SET calculation as it influences how quickly heat is transferred from the body, affecting perceived temperature and comfort.
