BUILDING ENERGY EFFICIENCY DIAGNOSTIC AND MONITORING SYSTEM
First Claim
1. A system to diagnose and/or monitor energy efficiency of a building, the system comprising:
- a. a first sensor module including a first temperature sensor, wherein the first sensor module is arranged to sense temperature outside of the building, the first sensor module including a data storage component for storing therein temperature information acquired by the first temperature sensor, and a communication interface;
b. a second sensor module including a second temperature sensor, wherein the second sensor module is arranged to sense temperature inside of the building, the second sensor module including a data storage component for storing therein temperature information acquired by the second temperature sensor, and a communication interface; and
c. a computing device configured to receive temperature information from the first sensor module and the second sensor module and to calculate;
i. a Cooling Rate of the building by calculating a difference between the temperature information from the second temperature sensor at a first time and at a second time divided by a time period defined by a difference between the first time and the second time; and
ii. an Effective Heating Rate of the building by calculating a difference between the temperature information from the second temperature sensor at a second time and at a third time divided by a time period difference between the second time and the third time.

Abstract
A system and related method are provided to diagnose and/or monitor energy efficiency of a building. The system includes temperature sensors positioned inside and outside the building. For various outside temperatures, the temperature differentials over time at the inside sensors are calculated over selectable time periods, whether for the entire building as a whole or for individual rooms. The temperature differential information is then used to determine energy efficiency of the building, including fuel costs/savings and improvements based on weatherization. The system includes standalone temperature monitoring modules or, alternatively, the system includes temperature monitoring modules that do not retain acquired temperature information but instead transmit that information to a networked device, such as an access point for wireless radio frequency signal transmissions.
