Abstract
As we observed in previous Chapter exercises, buildings generally benefit from HVAC systems that are designed to regulate their internal environmental conditions. As the name implies, in addition to heating and cooling, these systems also provide fresh outdoor (ventilation) air to dilute CO2 and other contaminants produced by building occupants, processes, and materials. Modeling HVAC systems correctly is one of the most challenging aspects of energy modeling because of the variety of systems and controls available and the design considerations that drive their selection. The goal of this Chapter is to discuss some of the general concepts needed to understand HVAC system modeling in the context of OpenStudio.

Notes
- 1.
OpenStudio does impose some limits on placement of components relative to the supply and demand side of Air Loops to prevent the user from accidentally creating Models that won’t simulate in EnergyPlus.
- 2.
ASHRAE (2016).
- 3.
