Indoor Environment of Buildings
• The indoor environment is the environment inside buildings. It is generally a physical reality that surrounds a living organism with which it interactsand which contributes to his physical condition constantly.
• It can be generally considered as a set of three phenomena, which are:

Indoor Environment (IE)
Perception of IE
• Reaction of organism to the environment:
– efforts to eliminate adverse effects in order to achieve comfort
• Conscious – e.g. taking a sweater on, closing window, running blinds
• Subconscious – e.g. sweating, shaking, eye accommodation
– Short-term X long-term effects

Environmental Comfort
„State of mind expressing satisfaction with the environment“
( Fanger 1970 - ASHRAE)
„Feeling of well being physically and mentally“ (European passive solar handbook)
„Indoor environmental quality is related to coexistence ofthermal comfort, visual comfort, indoor air quality and acousticcomfort.“ (Rehva Guidebook 13)
