System, method and apparatus for measuring energy loss

A system for quantifying building envelope energy loss for a building, the system comprising:

• a camera assembly, comprising a camera, for acquiring a building image set of said building envelope reflecting actual energy loss from the building envelope;
• a comparison image generator for generating a comparison image set using the building image set, data relating to said building, and a predetermined energy loss standard, the comparison image set reflecting a standard energy loss profile of the building envelope that meets the predetermined energy loss standard;
• an energy loss calculator for calculating at least one extent to which an actual energy loss exceeds the energy loss profile by comparing the building image set to the comparison image set and using exterior data as an energy loss calculation factor, the exterior data comprising a speed of wind associated with the building envelope;
• wherein the building image set comprises a plurality of pixels and the comparison image set comprises comparison image set elements, wherein each pixel of each building image set corresponds to a comparison image set element;
• and
• wherein the energy loss calculator compares the comparison image set to the building image set by comparing each comparison image set element to its corresponding building image set pixel.
