Building Commissioning
process of ensuring that system are designed, installed, and functionally tested for effective operation/maintenance for an owner’s operational needs.
Retrocomissioning
systematic investigation process applied to existing buildings to improve an optimize operating/maintenance.
Life Cycle Cost
provides a tool for determining long-term costs for the total building.
U-Factor
measure of heat transmission where a Low U-value has a slow heat loss or gain (brick wall) and a High U-value has a rapid heat loss or gain (window)
R-Vaule
measure of thermal resistance in a component. (U-Value = 1/R-Value) and
typically the opposite of an U-Value. Used to define level of insulation.
Thermal Inertia
ability of a material to store heat (concrete/masonry walls store heat in
an arid climate and release it slowly at night)
