ENVIRONMENTAL/ECOLOGICAL: ENERGY/HEATING/COOLING/AQUAPONIC SYSTEM
MCDONALD, JENSEN, THOMPSON | REWE+EC
This project features a sustainable building-integrated aquaponic system that exchanges 100 percent green electricty, rainwater collected on the rooftops, fresh produce/fish and their byproducts. The marketplace and atrium is a climate-controlled volume that uses intelligent cooling and heating technology with the stored energy from photovolatic solar panels. The rooftop greenhouse volume uses natural ventilation during the summer months. During the night and winter months stored energy is used for LED lighting for growing plants. This circular system reduces the overall use of rain water and electricity.

An aquaponic system produces significant amounts of sludge that could potentially be used and optimized by a bio-digestor. Sludge from the aquaponics can be used along with organic waste. Bio-gas and compost are produced and used for electricity and growing new produce. A circular system is created, supplying the community with clean energy and fresh produce.

REWE+EC: OVERVIEW OF BUILDING INTEGRATION
MCDONALD, JENSEN, THOMPSON | REWE+EC
Summer Solstice
Rainwater collects in crevases of greenhouse roof
Winter Solstice
Photovoltaic panels collect sunlight and operable windows allow for ventilation
A central atrium juts out, bringing in lots of natural daylight. This conserves energy that would otherwise be used on lighting the marketplace
Natural ventilation circulates throughout the greenhouse volumes in the summer months
ENVIRONMENTAL/ECOLOGICAL: ENERGY/HEATING/COOLING/AQUAPONIC SYSTEM
MCDONALD, JENSEN, THOMPSON | REWE+EC
The REWE green farming market is designed as a marketplace typology, emphasizing sustainable construction and on-site farming practices. As the pilot store in a planned series of stores, this market showcases adaptability in size and layout to its local site and is comprised of three elements (1) a ground floor marketplace, filled with regional produce and produce grown on-site; (2) simple and sustainable timber construction and energy use design; (3) produce grown in rooftop greenhouses using aquaponic systems. STAGE 1: Planting

This circular system reduces the overall use of rain water and electricity.
CONSTRUCTION/BUILDING INTEGRATION: MODULAR MASS TIMBER CONSTRUCTION
MCDONALD, JENSEN, THOMPSON | REWE + EC
The building construction consists of an important timber element, which is part of REWE’s future market strategy. The column itself consists of 12 layers. The elements are designed to be recognizable and easily built, with a simple timber construction that are scalable for all future REWE markets. The timber elements consist of locally produced wood and can be assembled with few screws. The stacked timber construction is designed to be modular, from market to market. The Construction function is a unifying element for all REWE markets. The building below the timber roof is supposed to house the specific REWE markets context.
ECONOMIC: MARKETPLACE TYPOLOGY
MCDONALD, JENSEN, THOMPSON | REWE + EC Regional
The REWE Green Farming Market is a protoype for a ”new adaptable and sustainable market concept, able to fit any site typology”. The long-term goal of the market chain is to connect shoppers to local produce and products in every market, including produce and fish grown on site and products from local farms. On a regional scale, branches will increase the variety of local produce offered by sharing rooftop-grown produce with each other. This strategy creates a series of regional zones: closed-loop networks that bring this movement to a national scale.

HISTORY, PRESENT, AND FUTURE OF THE DUWAMISH RIVER
DREDGING AND MAINTENANCE OF WATERWAY
In the early 1900s, the lower (northern) section of the river was straightened and dredged for industrial development. By the 1940s, channelization had transformed a 9-mile estuary into the 5-mile Lower Duwamish Waterway (LDW). Some of the dredged material was used to create Harbor Island and some was used to fill in parts of the old channel in Georgetown. Since 1916, the LDW has been regularly dredged by the US Army Corps of Engineers to support ship navigation.

HISTORY, PRESENT, AND FUTURE OF THE DUWAMISH RIVER
EXISTING SHORELINE CONDITIONS | SOUTH PARK
The present day waterway serves as a major shipping route for containerized and bulk cargo. Common shoreline features include constructed bulkheads, piers, wharves, buildings extending over the waters, and steeply sloped banks armored with fill materials. The Port of Seattle has begun several shoreline restoration efforts, notably at the Terminal 117 site. The intention is to restore natural floodplains and develop resilient landscapes.

Welcome to Catalyzing Connections! Our comprehensive plan aims to transform South Park into a vibrant and inclusive community. We will reconnect roads to Highway 99, establish a transit corridor, reactivate networks, implement a circular city framework, and introduce a fleet of vehicles delivering essential services.

MARKETPLACE
The Marketplace will introduce the opportunity to create a new community gathering space on the southwestern side of South Park. Residents will have access to fresh produce produced by the farm. Produce can be harvested and sold the same day of the week to avoid food waste and provide help addressing food desertification
BIODIGESTER
The Biodigestor drop-off and processing shed is connected to the greenhouse allowing for a direct exchange of input/ output of bio-waste & bio-energy. Trucks powered by South Park’s organic waste return to the tool shed to drop off waste by backing into the stalls. Fresh produce can be grown year round with the help of aquaponics systems housed by the new community space.
COMMUNITY SPACE
Marra Farm’s new community space fosters the connection between indoor and outdoor gathering. We believe that it is equally valuable to have accessible greenspace and fresh produce as it is to have indoor spaces to convene as a community. The farm grid merges with open space under shelter to extend the reach of community resources in this new hub. Agriculture and recreational landscape merge in this center for community members to enjoy. The new hub also features a rain garden, providing respite and restorative atmosphere and echoing restorative landscape design across the neighborhood’s interventions. The features are connected by series of covered walkways, providing access to indoor/outdoor community assets.
