This paper examines the urban form parameters in theories and ideas related to the urbanizing world. Adopting emergy (spelled with an “m”) synthesis, we studied New York City and the Greater Philadelphia region to determine the appropriate urban form, including building height, development density, bulkiness, and transportation. The European and North American mid-rise urban block is an effective settlement type for reducing per capita emergy in construction and building operations. Buildings over 40 stories with a development density exceeding a floor area ratio of 5 tend to show higher emergy investments per person. Large and bulky buildings with low surface-area-to-volume ratios that reside on the periphery of cities consume a significant amount of energy due to conditioning building space and the increased transportation needs for commuters.
