Carrot City: Urban Agriculture Exhibition in Toronto

60 Richmond St, Toronto - Teeple Architects

This project explores ideas for the future of urbanism in the North American city. It seeks to understand and express the notion that urban form can simultaneously be environmental form. We believe that our culture has a fundamentally different view of our planet than that held in the past century. We do not imagine the world as a vast resource to be tapped at our will, but limited, finite, and in an ongoing process of depletion. The unique client program was an inspiration for the design. 60 Richmond
is a housing co-op for union workers in the hospitality industry. The residential component is combined with a restaurant and teaching kitchen on the ground floor, owned and run by the tenants. Food for the restaurant is grown on the terraces and irrigated by storm water from the roofs. Compost from the restaurant is recycled to the
gardens, resulting in a state of urban permaculture. This link between the preparation of food and the growing process represents an attempt to enrich the social and educational attributes of the building.

Trent University Rooftop Garden

The Trent University rooftop vegetable garden utilizes the flat roof surface of the Environmental Science Building to create a productive roof that provides organic
produce for local groups interested in food security and sustainable agriculture. Among these is The Seasoned Spoon Café which has a mandate to source its ingredients locally thereby reducing the energy it takes to transport healthy food to consumers. It is the only restaurant of its kind at the university as it is a student-run,
independent co-operative. Increasingly, customers are aware of the varied components of local food culture, and their interdependence. Staff from “The Spoon” can often be found weeding, sifting compost, or harvesting food on the roof.

Science Barge

Science barge is a sustainable farm located on a four-hundred-square meter barge in midtown of Manhattan, New York City. The project was developed by the environmental non-profit organization, New York Sun Works in 2007 as a local food production and education centre for students, focusing on renewable energy, producing food with zero net carbon emissions, zero chemical pesticides, and zero runoff.

The project currently grows tomatoes, cucumbers, peppers, lettuces, yellow squash and herbs. Science Barge features a greenhouse hydroponic system that reduces land and water use. This system also helps reduce the carbon, particulate, nitrogen and sulfur oxide emissions by lowering the “farm-to-table distance”. To eliminate
the pollutants which come from fertilizers and pesticides, Science Barge uses insects to replace pesticides. Science Barge relies on renewable energy from solar photovoltaic
panels, wind turbines and bio-fuels. The wind turbines were carefully selected for urban settings and are able to cope with fluctuating wind conditions, and minimise noise disturbance. Bio-diesel that is produced by waste vegetable oil from agricultural and food industry by-products is also used. Annually, there is thirty eight million liters of waste oil available for generating bio-diesel from the New York City restaurants.

Vertically Integrated Greenhouse

The Vertically Integrated Greenhouse (VIG) combines a doubleskin building facade with a hydroponic greenhouse, offering one pathway towards energy efficient buildings that can grow their own food.

The Vertically Integrated Greenhouse (VIG) is a highly productive, lightweight, modular, climatically responsive system for growing vegetables within a double skin façade. The system is achievable with esisting technology. A south facing, vertical glazed façade at the relatively high latitude of the UK admits a fairly even distribution of sunlight throughout the year. Compared to a conventional greenhouse, the VIG provides increased production in winter, when produce prices peak. Plants are grown on trays suspended by a simple cable system, and all crop management occurs at the bottom level. Systems modules can rise as high as 10 or 20 stories each. An adaptive
control system alters the angles between rows of plants in the manner of Venetian blind, maximizing solar absorption diurnally and seasonally.

Greenhouse crops add a significant financial return to the base case for a double skin façade, which centers on enhanced winter heat gain and noise control. The crops also shade the interior.
