Unfortunately for those studying topics ranging from the history of architecture to the potential for cites to improve their energy efficiency, there is no worldwide inventory of our built environment. This paper helps to solve this problem by showing how by using publicly available satellite and street level views it is possible to remotely and accurately measure the dimensions of buildings and their main components such as width-height ratios or the fraction of a facade that is glazed.
This novel approach is applied to the question of fenestration by remotely completing a survey of 124 randomly selected buildings in 6 cities. The accuracy of the method is verified using a subset of buildings for which the dimensions are known. The results provide the first estimate of how glazing ratios vary with location.
The approach is transformative and shows that with a combination of publicly available images and the use of crowdsourcing it is now possible to accurately and remotely survey complete cites and obtain the dimensions of major retrofit elements, or make studies of the evolution in time of various architectural elements
