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.
Agro-Housing will promote the idea of sustainability and will dramatically reduce environmental problems in an era of globalization and urban migration.
The greenhouse is a multi-level structure for cultivating crops such as vegetables, fruit, flowers, and spices. It is equipped with a drip-irrigation system, a heating system, and natural ventilation.The Agro-Housing project suggests spaces for community activities. The greenhouse may serve as a place of casual or professional meetings. The roof garden offers an open air green space for recreation and informal gathering. The sky club on the roof is designed to host social gatherings and celebrations, and the ground floor kindergarten welcomes young children close to home and their parents. The Agro-Housing project provides diverse spaces for the benefit of its inhabitants.
The Agro-Housing project has a minimal footprint in order to free maximum ground surface for gardening and rainwater harvesting. The materials used for paving are recycled and cover limited surfaces. The parking area offers a large number of spaces for bicycles in the shade. The garden vegetation uses the natural cycles of the local environment to harmonize the landscape.
Communal Spaces – The agro-housing project provides a diversity of spaces for the benefit of its inhabitants such as kindergarten on ground floor and sky club surround with green roof on top.
The Greenhouse – The vertical agro-space permits production of fresh food for families and the community reducing commuting and creating a harmonic and holistic environment of sustainable life in urban space.
Natural Ventilation – The inner vertical space in the building is functioning as a ventilation shaft for the apartments as well as for the greenhouse. The apartments benefit from cross natural ventilation and the balconies and shades reduces cooling loads. In summer the opening of the top level of the atrium space will create a thermal chimney and enable air circulation pumping the hot air out and allowing fresh cold air to flow indoor.
Shading – In summer the greenhouse floors will serve as vertical screens and shades along with the greenery for cooling the inner part of the building. South facing apartments have shaded balcony blocking the summer sun.
Energy & Lighting – Day lighting will minimize the building’s need of artificial lighting. Responsible use of lighting, occupancy sensors, and timing devices, dimmers controls will be integrated in the building.
Passive Solar Energy – In winter, the low angle winter sun will penetrate the building and heat the high mass elements which will absorb the energy during the day and discharge it at night. The greenhouse glazed wall will trap hot air that will circulate in the building.
Active Solar Energy – Solar heating system delivers heat energy from the collectors on the roof to each apartment by forced circulation system.
GSHP – Ground source heat pump using high water table constant ground temperature all year round to provide heating and cooling system without combustion of fossil fuels, carbon monoxide or carbon dioxide.
Water Efficiency & Conservation
Drip Irrigation – Reducing water consumption by delivering irrigation directly to the plants and by collecting water that realized though evaporation. Stop leaching of nitrogen to under ground water table by using a smaller volume of water. Recycling drainage water and reusing them for production of crops by using advanced structures and soil less media containers.
Indoor Efficiency Water Use – Using high efficiency fixtures and dual water supply systems for potable water and reclaimed water.
Rainwater Harvesting – Capturing the rainwater from roofs and balconies for the use of irrigation of greenhouse and garden water preservation. Planting drought tolerant plants to increase the efficiency and the conservation of water.
Protection of the environment. Waste Management – reduction of waste generated by tenants by providing an easy accessible storage for waste recycling.
Vegetation – The intensive use of vegetation mainly in the greenhouse and on the balconies will contribute significantly to the reduction of carbon dioxide and the creation of a cooling effect and shading in the building.
The proposed structure of the building will be composed of metal columns and beams on a grid of 10×9. On top a deck flex sheets a concrete topping of five centimeters thick will be applied. This light steel structure will be prefabricated and installed on site. The concrete staircase will consolidate the building structure. This prefab steel system will create flexible spaces in the building and will contribute to the sustainability of the project. In the end of life of the building it will be easy to recycle.Facades
The exterior panels will be prefabricated under a modular facade grid. The glazed panels will have sliding shading in the same dimension. The other panels on the façade will be covered with terracotta tiles.
The choice of materials in the building will take under consideration their thermal qualities and abilities to be recycled at the end of life of the building.
Using structurally insulated panels to determine the energy efficiency of the building and reduce future expenses on energy loss.Bathrooms
The bathrooms units will be prefabricated including the duct work and piping. These units will be installed in the apartment and will create the core unit in the apartment.
The partition of the interior space of the apartments will be subject to the individual choice. The design will allow the tenants to decide about the preferred distribution of spaces in their own place to create their personal home. All the partitions will be made of light plaster panels that can be moved and recycled very easily.
The estimated cost of construction per square meter is about 200 euros,
Divided approximately as follow:
Structure and facades: 110 €/m²
Electricity, plumbing and air-condition: 45 €/m²
Bathrooms and kitchen: 30 €/m²
Interior partitions and finishes: 15 €/m²
Greenhouse: 30 €/m²
Agro-Housing will reduce the air and soil pollution by cutting the need for transportation and freeing a large quantity of agriculture fields for forestation.
Agro-housing will create jobs within the neighborhood and will permit more independence to people.
Irrigation -The use of water for irrigation of the greenhouse and gardening will be from the exiting high water table on the site saving water from city system.
Rainwater Harvesting – From the roofs and balcony rainwater will be collected for gardening saving potable water from the city system.
Flexibility -The planned flexibility of the interior space of the apartments will make possible to change partitions position and redesign of apartments with minimum energy and cost.
Building Envelope -The simple rectangular box represents a building with an economic envelope that can achieve an efficient energy saving and excellent thermal factors.
High-rise Building – The gathering of four apartments around each core of staircase and elevator will free land for rain harvesting and extra gardening and will contribute to the sustainability of the building.
End of life – Most materials suggested for the construction of the building such as steel, aluminum, glass and terracotta tiles will be moved from the site and recycled at a reasonable cost.
Local Resources –The local industry and expertise will be integrated in the detailed design of the building to maximize the identification of the people in the area with ideas of sustainability and preservation.

The media and communications campus in Neve Ilan is a unique place, as this is the only site in Israel where TV news can be broadcasted beyond Jerusalem.
Currently On-site there are a few gray buildings with a poor outward appearance; therefore, we decided to create a new vision for Israel’s national communications center. The site is located in a place where it is viewed from Highway 1, a main highway that leads to and from Jerusalem. As a result the external visibility of the campus is important in regarding branding and the accessibility of the campus to the general public.
The architectural vision of the project includes upgrading the existing studio buildings and the communication structures, in addition to planning the future buildings on site. Which include commercial and office space, hotel rooms and an Event & Conference Center.
A special emphasis is placed on the design of the public spaces on campus. The design includes public squares and plazas in front of the clusters of buildings, dwelling areas and green areas.
The project was designed with ecological attention and therefore there are energy saving systems and green building that are integrated within the design in order to strengthen the advanced technology and design this project creates.
