While an enormous amount of infrared techniques to look at building efficiency have been developed in the past, recent new testing combining aerial infrared surveys, handheld infrared measurements, pressurization and computational analyses have been developed, with some surprising results. These testing protocols and the results now point the way to suggested changes in the construction of “Big Box” buildings, the repair and weatherization of existing commercial buildings, and a methodology for prioritizing optimal solutions, based upon the net present value of any efforts for improvement relative to projected energy costs.

This paper will explore large big box commercial retail building design flaws and construction defects. These buildings of between 100,000 and 200,000 square feet typically have slab floors, flat or low-sloped roofs and 20’-30’ high walls. These buildings look like big boxes, hence the name. Design and construction, HVAC and lighting issues will be discussed, but no attempt to address energy usage issues such as water heating, refrigeration, computers and office equipment, or other energy uses in these buildings.
