Activity 4

10. • incorporates the conditions inside a building; air quality,
lighting, thermal conditions, ergonomics, visual comfort,
acoustic and their effects on occupants or residents.
• Buildings, as a kind of third skin.
indoor environmental quality (IEQ)

11. Relationship between Comfort Level and Performance Ability
Physical and mental performance capacity related to room
temperature was determined by researches
• it shows that, from room temperatures of about 25°C to 26°C
upwards, performance capacity noticeably decreases.
• From 28 to 29°C onwards, work efficiency clearly decreases.

12. Heat emission rates for a person as
it relates to surrounding environmental temperature.
From a temperature of 34°C, the body can
exclusively emit heat via evaporation (sweating),
since the surface temperature of the human skin
is also 34 °C.
