Part 2: Understanding Load Calculations and the Impact on Building Systems

What You Will Learn

Building load calculations are a fundamental building block of HVAC system design, and the single largest contributor to oversizing. In Part 1 of this series, we covered the different types of load calculation methods as well as internal and external loads. We also talked about different types of loads and how they impact the building HVAC load.

In Part 2, we’ll discuss system level loads, developing a load profile,  as well as why a load profile is critical to understanding the operation of the system. We’ll talk about plotting system operation on a psychrometric chart, which is crucial to understanding how coils will perform under various load conditions. Lastly, we’ll cover heating load estimates and how the building load is influenced by the outdoor ambient and building construction choices. We guarantee this series will help you improve your future building projects.
