MEEB Chapter Four : Thermal Comfort

Which intersection of relative humidity and air temperature is outside the ASHRAE thermal comfort zone?

60% and 86 deg F (30 deg C)

As air temperatures approach those of our own body, this mechanism for heat flow becomes essential

Evaporation (sweat)

List the three categories of factors that affect comfort:

Personal Measurable Environmental Psychological

The heat transfer process of conduction is primarily dependent upon

a difference in surface temperatures

1 CLO is equivalent to

a typical American man's business suit in 1941

Passive House comfort criteria set a maximum limit on

air velocity (less than 19.7 fpm)

The Passive House concept is best described as

an energy standard and set of design and construction principles

Humphreys and Nicol's equation for indoor comfort differs from other comfort models in that

it does not take relative humidity into account

The ASHRAE thermal comfort zones, as plotted on a psychrometric chart, are primarily defined by these

relative humidity and operative temperature

Mean radiant temperature

the uniform temperature of a surrounding enclosure in which radiant transfer from the human body would equal the actual radiant heat transfer within a building space

What is the recommended low humidity limit for the ASHRAE thermal comfort zone?

there is no recommended low humidity limit

At 100% relative humidity

wet-bulb temperature is equal to dry-bulb temperature
