Engineering and Urban Design
The Northeast is the most densely populated region of the country– a region where the design of the built environment determines the ability of communities to adapt to a changing climate, as well as their ability to advance the ecological, social, and economic dimensions of sustainability. The construction, operation, and maintenance of the built environment also represent key components of our region’s portfolio of greenhouse gas emissions, making infrastructure decisions central in devising pathways toward carbon neutrality.
Researchers in CCRUN’s engineering and urban design cross-cutting theme undertake stakeholder-driven, applied research that helps our external advance synergistic adaptation, mitigation, and sustainability goals. The team's research explores both tradeoffs and opportunities, seeking to co-develop new multifunctional infrastructure strategies together with our governmental and non-governmental partners.
Current Research:
Flood Risk Reduction
The CCRUN team is developing hydrologic and hydraulic models to assist in flood risk reduction (FRR) projects in Philadelphia, PA; Camden, NJ; and Manahawkin, NJ. In all three cases, researchers calibrate modeling tools to observed flows and high-water marks, and then use the validated models to evaluate the efficacy of engineered and nature-based FRR strategies under both current and future climate conditions. The simulations investigate how sea level rise, changes in the amount and/or intensity of precipitation, and their co-occurrence affect flood extent and depth. An additional area of focus is investigating the impacts that FRR strategies can have on local ecosystems and communities, as well as their life cycle costs and embodied energy.
Urban Heat Mitigation
The CCRUN engineering and urban design team's heat research focuses on the role of buildings, green spaces, and shade structures on determining the urban microclimate. In New York City, researchers have been collaborating with the Jacob K. Javits Convention Center to better understand how its green roofs and rooftop farm impact the facility’s water and energy consumption. They are also exploring the impact of shading and reflections from the recently constructed Hudson Yards buildings on the surrounding streets.
In Philadelphia, we have been monitoring urban microclimatic conditions in some of the city’s most heat vulnerable communities, to better understand how street orientation, street tree canopy, and other urban design configurations impact the microclimate. The project has also involved construction and monitoring of 300 unique, street-scale shade structures in five different neighborhoods around the city.
Nature-based solutions to the climate emergency
Building on prior work, the team continues to study how natural systems can be harnessed in support of climate change adaptation and mitigation efforts. This multi-disciplinary work spans the fields of urban planning, ecohydrology, water-resource engineering, and climate science, involving both field and laboratory studies, and complex sensor networks.
