Remote Facade Surveying of Windows Characteristics

Abstract Currently, there is no worldwide inventory of our built environment. This paper helps to solve this problem by showing how to remotely and accurately measure the dimensions of buildings and their main features. The approach presented here is applied performing a survey of 124 randomly selected buildings in 6 cities focusing on fenestration. The accuracy of the method is verified using a subset of buildings. The results provide the first estimate of how glazing ratios vary with location. The approach is transformative and shows how to accurately and remotely survey complete cities and obtain dimensions of major retrofit elements.
