BUILDING ENERGY ANALYSIS AND MANAGEMENT SYSTEM
First Claim
1. A system for HVAC analysis comprising:
- a transceiver configured to receive one or more HVAC determined values, wherein at least one HVAC determined value comprises a value based on fluid flow rate through a pressure independent valve;
a measurement predictor configured to predict one or more expected measurements for one or more HVAC determined values;
a comparator configured to compare one or more of the HVAC determined values with one or more of the expected measurements such that a difference value is determined;
an inference component configured to determine a probable cause based on a match between the difference value and one or more known difference values;
an optimization component configured to determine one or more changes to a building component or process based on the difference value or probable cause;
wherein the transceiver is further configured to send one or more signals based on the optimization.

Abstract
This application relates to a building energy analysis and management system for measurement and verification of building performance. The system can analyze, optimize, manage, maintain, trouble shoot, and/or modify building systems, such as HVAC systems, in connection with the building energy usage. Measurements may be gathered for one or more HVAC units coupled to pressure independent valves, and sent to one or more Surge Panels that pass data to remote analysis servers, which can receive other system or external data. The analysis servers compare measurements to predicted values and can standardize the predicted values to account for external conditions. The comparison can result in difference values used to generate probable causes and optimization recommendations. The system outputs reports or other data display using a graphical user interface that can be adjusted for an anticipated user.
