Architects and planners have been at the forefront of envisioning a future built environment for millennia. How ever,fragmental view s that emphasize one facet of the built environment,such as energy,environment,or groundbreaking technologies,often do not achieve expected outcomes. Buildings are responsible for approximately one-third of w orldw ide carbon emissions and account for about 40% of primary energy consumption in the U. S. In addition to achieving the very ambitious goal of reducing building-associated greenhouse gas emissions by75% by 2050,buildings must improve their functionality and performance to meet current and future human,societal,and environmental needs in a changing w orld. In this article,w e introduce a new framew ork to guide potential evolution of the building stock in the next century,based on greenhouse gas emissions as the common thread to investigate the potential implications of new design paradigms,innovative operational strategies,and disruptive technologies. This framew ork emphasizes integration of multidisciplinary know ledge,scalability for mainstream buildings,and proactive approaches considering constraints and unknow ns.The framew ork integrates the interrelated aspects of the built environment through a series of quantitative metrics that aim to improve environmental outcomes w hile optimizing building performance to achieve healthy,adaptive,and productive buildings. 展开更多
