SYSTEM AND METHOD FOR CALCULATING THE THERMAL MASS OF A BUILDING
First Claim
1. A system for calculating a value for the operational efficiency of an HVAC system comprising:
- at least one HVAC control system that receives temperature measurements from at least a first location conditioned by at least one HVAC system;
one or more databases that store at least said temperatures measured at said first location over time; and
one or more processors that receive outside temperature measurements'"'"' from at least one source other than said HVAC system, wherein said one or more processors are configured to calculate one or more rates of change in temperature at said first location for periods during which the status of the HVAC system is “
on” and
wherein said one or more processors are further configured to calculate one or more rates of change in temperature at said first location for periods during which the status of the HVAC system is “
off'"'"', and to relate said calculated rates of”
change to said outside temperature measurements

Abstract
The invention comprises a system for calculating a value for the effective thermal mass of a building. The climate control system obtains temperature measurements from at least a first location conditioned by the climate system. One or more processors receive measurements of outside temperatures from at least one source other than the control system and compare the temperature measurements from the first location with expected temperature measurements. The expected temperature measurements are based at least in part upon past temperature measurements obtained by said HVAC control system and said outside temperature measurements. The processors then calculate one or more rates of change in temperature at said first location.
