Building envelope and interior grading systems and methods
First Claim
1. A grading system for a building, comprising:
- one or more processors;
memory including instructions that, when executed by the one or more processors, cause the one or more processors to;
receive, from sensors of a building over a network, indoor temperatures of the building and outdoor ambient temperatures at the building;
determine differences between the outdoor ambient temperatures of the building and the indoor temperatures within the building;
determine a first average of the differences of a first day;
determine a second average of the differences of a second day;
store a first data point for the first day, the first data point including the first average and a first total run time of a heating, ventilation, and/or air conditioning (HVAC) system of the building during the first day;
store a second data point for the second day, the second data point including the second average and a second total run time of the HVAC system of the building during the second day;
fit a line to the first and second data points;
determine a slope of the line;
generate a first grade for an exterior envelope of the building based on the slope of the line;
based on the line, determine a third total run time of the HVAC system where a third average of the differences is equal to zero;
based on the third total run time where the third average of the differences is equal to zero, generate a second grade for internal thermal loads within the building, thermal deficiencies within the building, and deficiencies of the HVAC system of the building;
generate a displayable report for the building including the first grade of the exterior envelope of the building and the second grade; and
transmit the displayable report to a user computing device associated with the building.

Abstract
A difference module determines differences between an outdoor ambient temperature and an indoor temperature, determines a first average of the differences, and determines a second average of the differences. A storing module stores a first data point, the first data point including the first average and a first total run time of a heating, ventilation, and/or air conditioning (HVAC) system, and stores a second data point, the second data point including the second average and a second total run time of the HVAC system. A fitting module fits a line to the first and second data points. An envelope grading module generates a grade for an exterior envelope of a building based on a first characteristic of the line. An interior grading module generates a grade for an interior of the building based on a second characteristic of the line. A reporting module generates a displayable report for the building including the grade of the exterior envelope and the grade of the interior of the building.

11. A grading method for a building, comprising:
-
by one or more processors, receiving, from sensors of a building over a network, indoor temperatures of the building and outdoor ambient temperatures at the building; by the one or more processors, determining differences between the outdoor ambient temperatures of the building and the indoor temperatures within the building; by the one or more processors, determining a first average of the differences of a first day; by the one or more processors, determining a second average of the differences of a second day; by the one or more processors, storing a first data point for the first day, the first data point including the first average and a first total run time of a heating, ventilation, and/or air conditioning (HVAC) system of the building during the first day; by the one or more processors, storing a second data point for the second day, the second data point including the second average and a second total run time of the HVAC system of the building during the second day; by the one or more processors, fitting a line to the first and second data points; by the one or more processors, determining a slope of the line; by the one or more processors, generating a first grade for an exterior envelope of the building based on the slope of the line; by the one or more processors, based on the line, determining a third total run time of the HVAC system where a third average of the differences is equal to zero; by the one or more processors, based on the third total run time where the third average of the differences is equal to zero, generating a second grade for internal thermal loads within the building, thermal deficiencies within the building, and deficiencies of the HVAC system of the building; by the one or more processors, generating a report for the building including the first grade of the exterior envelope of the building and the second grade; and by the one or more processors, transmitting the displayable report to a user computing device associated with the building. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
