Maintain Site-BasedStormwater Detention Systems

Issue: Site-based stormwater diversion anddetention systems must be properly maintainedto be a reliable component of the city’s storm-water infrastructure.

Recommendation: Establish maintenance standards for site-basedstormwater systems, and require property owners toverify compliance.

Reduce Summer Heat with Cool Roofs

Issue: Light-colored roofs reflect light and heat backinto the atmosphere, thereby cooling buildingsand cities. The building code mandates white roofcoatings, but the standards are not aligned withLEED, which is used by many developers.

Recommendation: Amend specifications for cool roof coatings to alignthem with LEED.

EF 12Reduce Summer Heat withCool, Shady Building Lots

Issue: Unbuilt areas on private building lots make upapproximately one third of New York City’s space.Because these areas are often covered in dark,unshaded pavement, they contribute to the city’sheat island.

Recommendation: Require light-colored pavement, trees or plantingson 50% of the unbuilt areas of building lots.

SW 5Encourage InnovativeStormwater Practices

Issue: Modern stormwater control systems incorporateboth civil engineering strategies, such asunderground detention tanks, and landscape-based strategies, such as green roofs and naturallandscaping. New York City’s regulations, however,do not properly account for the impact oflandscape-based strategies.

Recommendation: Revise stormwater regulations to account forlandscape-based strategies.

But what about...

Embodied energy?

Product lifecycle?

Materiality?

Construction sequence?

What about all the aspects of the element that deal with time and not just space?

ShadeStructuredraws on experience gained from the RainRoof to pro-duce a more lightweight, inexpensive canopy structure that includes parameters related to constructability.

While the RainRoof addressed some metrics of realapplication (structural and water weight), it focused onadaptability of the element to a wide range of contextswithout considering how the element would actuallybe used in those contexts. This element rethinks theoriginal design intents from scratch. Situ Studio, Solar Pavilions - demountable, “crowd-sourced” construction

with minimal production waste, recyclable materials, low cost

Self-Supporting Structure: Three-Hinged Arch

The pieces lock together with circular inserts. Option-ally, fabric or non-permeable material can be stretchedacross the top for additional shading, or to direct water into tubes that can run through the center of the as-sembly.

Design Development






Fins + Louvers

The fin height is standardized, while the louvers can varyin length and angle. The sizes and lengths of the louverscan be changed, as can certain aspects of the fins.

The entire assembly is easy to manufacture, assemble,and dis-assemble; creates shade; and contributes to aninteresting outdoor environment.

Assemblies of fins plus louvers are then arrayed to

achieve a complete shading system.

“Fin”: adjusts inwidth, length, anddegree of curvature

Louvers: adjust in thick-ness, angle, and length;

can be turned on and off
