Strategy Guideline: Accurate Heating and Cooling Load Calculations

This guide presents the key criteria required to create accurate heating and cooling load calculations and offers examples of the implications when inaccurate adjustments are applied to the HVAC design process. The guide shows, through realistic examples, how various defaults and arbitrary safety factors can lead to significant increases in the load estimate. Emphasis is placed on the risksincurred from inaccurate adjustments or ignoring critical inputs of the load calculation.
