Another name for 'house-as-a-system' - 'whole-house' approach
Any type of work done on the house such as air sealing, adding insulation, replacing a door or window,
or installing mechanical ventilation will impact on the 'system' and how it functions? True or False -
True.
, If you change something you have to make sure something else doesn't need adjusted or added (ie.
ventilation) for a tight house. You can actually cause more damage by trying to make a house more
efficient if you do not think of the 'house-as-a-system or have a 'whole-house' approach when doing
retrofit work.

-roof
-doors
Mechanicals examples: - -heating
-cooling
-ventilation
-electrical (lighting & appliances)
-plumbing
Environment examples: - -interior temperature
-interior relative humidity
-indoor air quality: bringing in fresh air and reducing or eliminating pollutant concentrations
Occupant examples: - -The importance of occupant behavior cannot be understated (ie. use of lighting,
exhaust fans, and DIY improvements
-Occupants are the beginning and end of the system
