A Siberian Eco-city Inside a One Kilometer Crater

A Siberian Eco-city Inside a One Kilometer Crater | green streets |

Eco-city 2020 is a proposal for the rehabilitation of the Mirniy industrial zone in Eastern Siberia, Russia designed by the innovative architectural studio AB Elis Ltd.

The project would be located inside a giant man-made crater of more than one kilometer in diameter and 550 meters deep that used to be one of the world’s largest quarries. The idea is to create a new garden city shielded from the harsh Siberian environmental conditions and instead, attract tourists and residents to Eastern Siberia, with the ability to accommodate more than 100,000 people. The new city is planned to be divided in 3 main levels with a vertical farm, forests, residences, and recreational areas.

One of the most interesting aspects of the proposal is the glass dome that will protect the city and would be covered by photovoltaic cells that will harvest enough solar energy for the new development. A central core houses the majority of the vertical circulations and infrastructure along with a multi-level research center. The housing area is located in the first level with outdoor terraces overlooking a forest in the center of the city, in order to create a new type of highly dense urbanism in harmony with nature.

What Makes Some Cities Greener Than Others

What Makes Some Cities Greener Than Others | green streets |
Today I turn my attention to the economic, demographic, and other factors associated with cities and metros that have lower levels of carbon emissions.


Several Martin Prosperity Institute colleagues and I [Richard Florida] took a simple, straightforward statistical look at several things research and common sense suggest should be associated with higher and lower levels of carbon emissions.

We measure emissions three ways, as a function of population (per capita), workforce (per worker), and economic output (per economic output). All the caveats regarding correlation not being causation apply. However, our findings underscore the fact that carbon emissions are linked as much to the way we live as how we produce and manufacture things...

A SymbioCity in Malmö: From industrial area to city of tomorrow

A SymbioCity in Malmö: From industrial area to city of tomorrow | green streets |

A once decaying industrial area has transformed into an exciting, sustainable urban environment with a bright future. Sustainability inspired the architects behind this eco-city within a city. The Western Harbour now has its own energy supply and waste treatment system, very few cars – and plenty of satisfied residents.

Clean soil is the start of the eco-city: After decades of industrial and port activity, the soil at Western Harbour was so contaminated by oil residues that a clean-up was necessary before the area could be start its urban renewal.

Water: Surface water is managed via a network of open canals and dams. The system slows down rainwater flow and lush vegetation and vortex technology ensure favorable oxygen content and reduced algae growth. Green roofs on a significant number of the buildings add to the eco-friendly atmosphere.

Energy systems and eco-efficient buildings: The district is self-supporting in terms of energy use. A system powered by renewable energy produces heating, cooling and electricity for residents and is connected to the city's heating grid and power supply network.

Core of the energy system: The Aktern heat pump plant is the heart of the energy network and produces energy for heating and cooling. The energy is then stored seasonally in natural aquifers in wells. A local wind power plant provides the electricity needed to power the heat pumps and also supplies 1,000 apartments with electricity.

Solar cells on the roof:  Rooftops and walls are fitted with solar collectors, meeting 15 % of the the region's heating requirements. The system also includes solar panels.

Transportation: Planned as a standalone community with close access to goods and services, the Western Harbour has virtually no cars. Most residents walk to their homes. Bicycles and pedestrians have priority, and the area can be easily reached from the rest of Malmö on biogas buses operated by the local public transport company.
