Method and system for calculating energy metrics of a building and one or more zones within the building
First Claim
1. A system for calculating energy metrics of a building comprising:
- a first environmental sensor for measuring at least one of a temperature and a relative humidity of a first zone contained within the building;
a second environmental sensor for measuring at least one of a temperature and a relative humidity of a second zone contained within the building;
a thermostat in communication with the first and second environmental sensors, for passing data from the environmental sensors to a data acquisition unit;
the data acquisition unit storing and formatting the data received from the environmental sensors into a profile; and
an efficiency calculation system for receiving the profile from the gateway and determining one or more energy metrics for the first and second zones within the building, the efficiency calculation system providing energy metrics from other similar buildings in a geography containing both the building and other similar buildings.

Abstract
A method and system can provide building energy performance metrics that can help identify specific zones within a building which may have energy efficiency problems. The method and system can collect data from: indoor temperature sensors and humidity sensors present in each zone of a building; one or more temperature sensors and humidity sensors present outside of the building; one or more utility meters; and one or more HVAC devices. This data from the sensors can be aggregated and formed into a first profile. The energy efficiency calculation system can analyze the first profile to provide various energy performance metrics which can include, but are not limited to, energy efficiency ratios for air conditioners, the R-value or thermal resistance of the building, an amount of heat loss for the building, energy consumption by the building, current HVAC performance parameters, and utility usage comparisons.
