Standardized HVAC Sequence of Operations Savings Calculator

The project team developed the calculator based on stakeholder outreach, which identified the absence of an offering in efficiency programs that is flexible enough to account for building and system characteristics but simpler than a custom energy modeling approach. The team did extensive testing of energy modeling parameters to determine the 13 parameters with the greatest impact on measure performance. Based on feedback from stakeholders, most of the inputs are optional, allowing for greater accessibility and ease of use. The calculator includes an uncertainty analysis that accounts for the added uncertainty from unknown building parameters and returns a dynamically calculated uncertainty range.
