Last week’s snowpocalyspe for the Northeast underscored the growing need to address issues of resiliency across all development patterns. The combination of fast-tracked growth in new communities, an aging network of infrastructure and the possibility of increasingly frequent severe weather events continues to put the spotlight on the ability of municipalities to operate safely throughout unplanned disruptions. Though the focus often leans towards building systems and infrastructural safety, walkability can be a key component of a resilient community that can help keep neighborhoods functioning normally.

Contrary to the statements of some and the hopes of many, there are no silver bullets for solving challenges surrounding sustainability. Part of this is due to the complexity of the problems, some is due to the fact that there are so many points of view for problem solving and a piece of the responsibility falls on the fact that there are so many different situations around the world with unique contextual conditions, making their problems in turn unique. As a result, collaboration makes a world of sense as we approach sustainable goals and the best solutions can come from components that span cities, countries and even continents. Continue Reading…
In less than a year since its devastating run-in with Hurricane Sandy, the City of New York is already adopting new measures geared towards higher levels of urban resiliency. Yesterday, the City Council approved the first batch of proposals from the Building Resiliency Task Force, marking the first step for updating codes that leave the city better equipped for future storm events.

As parts of the Northeast leave behind days waiting for power and water, Hurricane Sandy’s late October run prompts the question of what we can do to make our urban areas more resilient to minimize the time that we need to keep residents without the bare essentials. There have been a number of articles (here and here) recently written about the comparison between “resiliency” and “sustainability” in an attempt to make a case for which we should ingrain into our cities. Facing the two terms against one another struck me as odd because though we can strive to satisfy one and not the other, there is a great deal of overlap between the two. Sustainable design and construction is often proposed on the merits of environmental stewardship, a healthier indoor environment and opportunities for monetary savings from increased efficiency, but its underlying goal also advocates quality, ensuring that we make buildings that will last over time. In many cases greener buildings can provide a better means of weathering the aftermath of the storm, leaving us better prepared for the inherent variability of nature. Continue Reading…
If you walk into the city on a sunny, summer day and feel like it is warmer than the suburban home you left earlier, it isn’t your imagination. The “Heat Island Effect” is a term that refers to a localized rise in ambient, outdoor temperature due to dark materials absorbing light from the sun. While asphalt roads contribute meaningfully, roofscapes are the most abundant culprit with a large number of existing flat roofs in this county being black—either tar, asphalt or a rubberized membrane. In full summer sun, a black roof can reach temperatures of 170 degrees. When the number of these roofs located in close proximity rises so does the amount of heat captured and radiated back into the air.
Though it is occurring at some scale on any dark-colored, man-made surface, the effects are most strongly felt in urban conditions where streets and the tops of buildings make up most of the net surface area facing the sky. In a city like New York, the result can be a local air temperature 5 to 10 degrees higher than surrounding townships in the depths of summer. Keep in mind, Manhattan is also on the coast which means that this temperature rise is happening despite the cooler normally found from coastal winds. Continue Reading…
