This collection addresses the critical challenge of creating environmentally friendly cities on a global scale. The 15th Passive and Low Energy Architecture (PLEA) conference convened architects and planners to explore strategies for reducing the environmental impact of urban areas and their structures. With approximately 150 papers presented, the proceedings delve into a wide array of questions and solutions pertinent to sustainable urban development. The focus is on practical applications and theoretical considerations for making cities more ecologically sound.

The proceedings of the PLEA 1998 conference, focusing on environmentally friendly cities, likely serve as a valuable resource for professionals and academics in architecture and urban planning. The collection's emphasis on sustainability and the reduction of environmental impact suggests a focus on practical and theoretical advancements in the field. The sheer volume of papers indicates a broad exploration of the challenges and solutions facing urban development in the late 1990s. This work would be of interest to those seeking to understand the state of passive and low-energy architecture at the city scale during that period.
