Context
Like many other cities on the east coast, Washington’s summers are hotter and heat waves last longer than anticipated just a few years ago. While vehicle drivers of all kinds (cars, bikes, scooters and mopeds) can keep cool through air conditioning or at least the movement of air at speed, pedestrians do not share in that advantage. Consequently, walking in areas without shade can be an unwelcome and sometimes dangerously hot enterprise. The danger comes not only from the sun shining down on a particularly hot day, but also the accumulated heat radiating out of the materials of the bridge or plaza over successive days of a heatwave. Often the people most vulnerable to heat-related illness, young children and older people, are the most likely to also be pedestrians. Making this infrastructure safer for them will make it more comfortable for everyone.
How hot is it exactly?
Measurements were taken on August 27, 2024, at 4:45 PM on the Duke Ellington Memorial Bridge. This was a typical 90+ degree day in DC, the first day in a predicted three-day heat wave. The air temperature was 91 degrees in the area. On the bridge the air temperature read 94 degrees. The pavement reading was 111 degrees. In areas of the bridge which have shade from trees in nearby Rock Creek Park the air temperature read 92 degrees, and the pavement was cooler at 89 degrees.
This shows that shade can really make a difference.
Competition Goal
This competition seeks to provide a well-designed flexible shade system or systems that can be used in areas where other means of shade, such as tree planting, are not possible. These areas include major bridges that carry both pedestrian and vehicular traffic, pedestrian-only bridges and transit-related open plazas. The ideal system will be durable and easily maintained. The system(s) must not impede travel or interfere with safety measures, such as suicide barriers, that are already in place. Consideration must also be given to wildlife that traverse the area.
Eligibility
The competition is open to all, including students and professionals in the fields of architecture, landscape architecture and engineering. Design proposals can be developed individually or by teams.
