How To Size Your Heating Or Cooling System
In the heating and cooling industry, determining the answer to that question is known as "sizing" your equipment, and the process is known as a load calculation or heat loss calculation. The following will help you understand why sizing a system is important and what steps HVAC Contractors take to determine the proper capacity for your equipment. ... View Doc

Heat Loss Calculations And Principles - CED Engineering
HEAT LOSS FROM BUILDING ENVELOPE (Wall, Roof, Glass) Heat loss occurs from a building structure primarily due to conduction. Because heat moves in all directions, when calculating the heat loss of a building, we much consider all surfaces (external walls, roof, ceiling, floor, and glass) that divide the inside, heated space from the outside. ...

Heat Gain Calculations | NaturalGasEfficiency.org
The formula used to calculate heat gain from thermal conduction (outside ambient temperature during the cooling season) is the same basic formula as the Heat Loss Formula, [(Square Foot Area) x (U-Value) x (Temperature Difference)]. If the space is mechanically cooled, every BTU of heat that gets in above the set-point, must be removed to ... Access Document
