Our summer of 2022 Passive House Accelerator magazine issue explores the theme of Outrage + Optimism, a phrase coined by Christiana Figueres, the former UN Climate Chief who ushered the Paris Agreement to completion and who urges us to harness both outrage and optimism to energize and sustain our climate action.
In this issue, we dive into how Passive House design will play a vital role in the future built environment, particularly by focusing on case studies from a wide range of building typologies in North America and beyond. These include a new mass timber multifamily in Boston, a mixed-use supportive housing building in Seattle, and an expansive residential project in Cartagena, Colombia—among several others. Gracing the magazine cover is Winthrop Center, currently under construction in Boston, which will contain the largest amount of Passive House certified office space of any building in the world when completed within the next year.
