ROOT[ED] 1

Design For Change The increased demand from a growing population is intensifying the pressures on our ecosystems and natural resources. It has forced us to alter our traditional farming techniques to practices that use nitrogenbased fertilizers to increase crop yields. Iowa, who devotes 89% of its land to farming now suffers water quality standards and irrecoverable soil depletion rates due to chemical runoff. If we were to continue down this path, Iowa’s soil will become unusable, and the state’s water undrinkable.

Rooted seeks to place interventions in the system for managing resource resiliency by incorporating an aquaponics greenhouse, production center, market, and residential units within the city of downtown Cedar Rapids, Iowa. This program forms a closed loop system in an urban fabric that allows Iowa to maintain its rank as a top farming state while reducing its impact on the environment, and providing a basic need for surrounding community members.

Reuse building materials

Building geometry maximizes rainwater collection

Connection to green space

Brick was used from the demolished building for planter boxes to help offset project waste and support site ecology. The planters also contribute to the building’s thermal mass.

The building’s roof is designed to maximize rainwater collection by sloping toward the bioswale system to accumulate rainwater in the middle courtyard. This design also promotes natural ventilation.

The hard-space on our site was designed to create a strong urban connection to the newly renovated Green Square Park. This connection influences pedestrian traffic to continue on the path into the market.
