Abstract
Abstract Disclosed is an energy measurement and verification system and method which provides real time documentation of both baseline and post-retrofit energy consumption. Actual energy savings are calculated with a unique combination of computer hardware, energy and data translation software, measurement protocols, and digital remote sensing equipment which monitor the energy consumption of the retrofit environment and a sample baseline environment.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
122 words
A method of determining the difference in thermal transfer between a first region and a second region, comprising the steps of: measuring the temperature at said first region to obtain a first temperature reading; measuring the temperature at said second region to obtain a second temperature reading; subtracting the first temperature reading from the second temperature reading to obtain a temperature difference; and multiplying the temperature difference by a value representative of the heat transfer coefficient for the environment in which the first and second temperature readings are obtained, thereby calculating the heat differential between the first region and the second region; wherein said first region is representative of a retrofit environment and said second region is representative of a baseline environment.
Claim 2
Independent Claim
122 words
A method of determining the difference in thermal transfer between a first region and a second region, comprising the steps of: measuring the temperature at said first region to obtain a first temperature reading; measuring the temperature at said second region to obtain a second temperature reading; subtracting the first temperature reading from the second temperature reading to obtain a temperature difference; and multiplying the temperature difference by a value representative of the heat transfer coefficient for the environment in which the first and second temperature readings are obtained, thereby calculating the heat differential between the first region and the second region; wherein said first region is representative of a retrofit environment and said second region is representative of a baseline environment.
Claim 3
Dependent Claim
42 words
The method according to claim 1, further comprising the step of multiplying the heat differential by a value representative of an area of a retrofit surface, whereby the total energy savings from the retrofit in comparison to a baseline environment is determined.
Claim 4
Dependent Claim
26 words
The method according to claim 2, wherein the baseline environment comprises a window and the retrofit environment comprises the window with energy saving film applied thereto.
Claim 5
Dependent Claim
32 words
The method according to claim 2, wherein the baseline environment comprises a roof, wall or floor, and the retrofit environment comprises the roof, wall or floor with newly applied insulation applied thereto.
Claim 6
Independent Claim
114 words
A method for measuring the energy savings obtained by retrofitting an environment with one or more energy saving materials, said method comprising the steps of: providing a first sample region representative of the environment after retrofitting with the one or more energy saving materials; providing a second sample region representative of the environment prior to retrofitting with the one or more energy saving materials; calculating a temperature difference between the first sample region and the second sample region; and calculating the energy savings provided by the one or more energy saving materials on the basis of the temperature difference and the area of the environment to which the energy saving materials has been applied.
Claim 7
Independent Claim
114 words
A method for measuring the energy savings obtained by retrofitting an environment with one or more energy saving materials, said method comprising the steps of: providing a first sample region representative of the environment after retrofitting with the one or more energy saving materials; providing a second sample region representative of the environment prior to retrofitting with the one or more energy saving materials; calculating a temperature difference between the first sample region and the second sample region; and calculating the energy savings provided by the one or more energy saving materials on the basis of the temperature difference and the area of the environment to which the energy saving materials has been applied.
Claim 8
Dependent Claim
78 words
The method of claim 5 wherein the energy savings is calculated according to the following expression: Q.sub.SAVINGS =(t.sub.B -t.sub.R)hA where (t B -t R ) is the temperature difference between the first sample region and the second sample region, h is the heat transfer coefficient of the region surrounding the first sample region and the second sample region and A is the area of the environment to which the one or more energy saving materials has been applied.
