Over the past few months we have worked with EXPO SpA, the local institutions and the BIE (Bureau International des Expositions) to create a revolutionary new concept of the world exposition. We are convinced that a visionary and successful EXPO has to abandon the outmoded idea of an exposition built around complex systems of representation and gigantic architectural monuments which often have no real purpose after the event. Instead EXPO 2015 will be remembered for giving visitors a direct and immediate experience of all aspects of the question of food. It will be an EXPO that embodies its theme-Feeding the Planet, Energy for Life-directly within its own space, with none of the usual simulations and documentation that can easily be found today on any computer. Secondly, it will be an EXPO that overturns the whole concept of monumentality: in place of giant structures (like the Eiffel Tower of Paris 1898), Milan will build a new landscape of monumental lightness and natural beauty. An environment that reflects the environmental sustainability, technical precision and haunting beauty of Venice’s winding alleys, Leonardo’s canals and the open countryside of rice fields and vineyards. The EXPO we envisage will be a Planetary Botanical Garden open to the citizens of Milan and the world. A place for a fresh encounter between farming and the city that will feed Milan literally, spiritually and intellectually. A vast agrofood park built on an orthogonal grid, surrounded by water ways and punctuated by striking landscape architecture.  READ MORE »

The Process

The Seawater Greenhouse uses the sun, the sea and the atmosphere to produce fresh water and cool air. The process recreates the natural hydrological cycle within a controlled environment. The entire front wall of the building is a seawater evaporator. It consists of a honeycomb lattice and faces the prevailing wind. Fans assist and control air movement. Seawater trickles down over the lattice, cooling and humidifying the air passing through into the planting area.

Sunlight is filtered through a specially constructed roof, The roof traps infrared heat, while allowing visible light through to promote photosynthesis. This creates optimum growing conditions - cool and humid with high light intensity.

Cool air passes through the planting area and then combines with hot dry air from the roof cavity. The mixture passes through a second sea water evaporator creating hot saturated air which then flows through a condenser.

The condenser is cooled by incoming seawater. The temperature difference causes fresh water to condense out of the air stream. The volume of fresh water is determined by air temperature, relative humidity, solar radiation and the airflow rate. These conditions can be replicated in the thermodynamic model and, with appropriate meteorological information, the detailed design and performance of the Seawater Greenhouse can be optimised for every suitable location and environment.  READ MORE »

What is the Science Barge?

The Science Barge is a prototype, sustainable urban farm and environmental education center. It is the only fully functioning demonstration of renewable energy supporting sustainable food production in New York City. The Science Barge grows tomatoes, cucumbers, and lettuce with zero net carbon emissions, zero chemical pesticides, and zero runoff. It is powered by solar, wind, and biofuels, and irrigated by rainwater and purified river water.  READ MORE »

Agro Housing

Knafo Klimor Architects of Israel - Winners of the 2nd International Architecture Competition for Sustainable Housing. China 2007

Conceptual Approach
According to a UN report, in 2010 about 50% of the Chinese population will reside in cities. This huge migration from rural regions to new urban megalopolises will create a dramatic cultural and social crisis, a loss of existing traditions and considerable unemployment. Massive urbanization will form random communities, severely deplete natural resources, exhaust urban infrastructures and transportation systems, and will increase air and soil pollution.
The concept of Agro-Housing is a new urban and social vision that will address problems of chaotic urbanization by creating a new order in the city and more specifically, in the housing environment.
Agro-Housing is a program that combines a high-rise apartment complex with a vertical greenhouse within the same building.
The idea behind Agro-Housing is to create a close to home space where families can produce their own food supply according to their abilities and choices. This will allow the citizens more independence, freedom, and additional income.  READ MORE »

Inspiring Learning and Action

What we eat, where we eat, and how we eat reveals much about our relationship to food. Today, more than ever, we need to understand where our food comes from and how it reaches us. The purpose of Nourish is to open a broad public conversation about our food system that encourages citizen engagement, particularly among young people and families.

Nourish PBS Special

Launching in fall 2008, the nationally broadcast, high definition PBS special entitled Nourish explores the abundant possibilities to create a sustainable food system. The special traces our relationship to food from a global perspective to personal action steps.  READ MORE »
