Load Estimating, Level 2: Fundamentals

The fundamentals of commercial load estimating are needed to understand the various load components that go into making a practical estimate of the amount of heating and/or cooling energy needed to condition a building. Done properly, a load estimate provides the data necessary to select heating and cooling equipment that can condition the occupied spaces within a building. In the earliest stages, the load estimate will tell the designer how big the job is, either in terms of cooling capacity, expressed as tons of refrigeration, or in terms of airflow cfm. If the characteristics of the loads for the building and the HVAC system are known, then an analysis of the application can be used to come up with the correct load and equipment selections to complete the design. Along with psychrometrics, load estimating establishes the foundation upon which HVAC system design and operation occur.
