As expected the Vancouver Winter Olympics, made every effort to ensure that the Olympic Village, Millennium Waters, was as eco-friendly as possible, but while doing so they have actually managed to develop the Greenest, most energy efficient and sustainable Neighborhood in the world!
Millennium Waters, is located on Southeast False Creek across from the BC Place Stadium and its close proximity to the city center was only one of the many factors that resulted in receiving both a LEED Platinum certification for the entire neighborhood and a LEED Gold status for all of the buildings included in the village.
The newly-constructed village, features the city’s first renewable energy heating system, net zero energy building (a structure that produces as much energy as it consumes), natural and non-toxic building materials, devices capable of measuring the energy and water used by occupants, solar panels and solar hot water systems generating power for the households and many- many more eco features. Wow! 
2.600 athletes and coaches are the current occupants of the Village although once the Games are over, individuals will be able to buy the award winning condos and homes and live in this greener than green, true mixed-use complex.
The Eco City Montecorvo is a masterplan for a sustainable city by MVDRV envisioned on the two small hills of Montecorvo and La Fonsalalda. The development uses the south facing hills to provide beautiful views of the city and also maximize the use of both passive and active solar energy.
The development will provide optimal conditions for solar energy generation using photovoltaic cells. Apart from harnessing solar energy, the development will also incorporate windmills that stand on top of the hills to catch the wind. Combined, the solar and the wind energy generators will have the ability to provide all the energy the 3000 unit housing community needs.
Only 10 percent of the site is to be occupied by buildings, which minimizes the impact on the landscape and simultaneously minimizes building costs. Due to the height differences, each apartment takes maximum advantage of the views.
The roofs of the lower situated slabs have been made accessible and offer possibilities to create a magnificent public space overlooking the landscape of the La Rioja. By producing all the energy needed on the 56 hectare site from renewable sources, the new neighborhood achieves a CO2-neutral footprint.
However, there are signs that some of this good work is being undone and the city is becoming more famous as a seedy tourist destination and is also getting ready for the 
Inhabitants of Xeritown will also be protected by the dangerous desert sun since most of the buildings will be tall enough to block out the sun for most of the day, and walkways leading along shops and homes will have significant overhangs, so people can walk in almost complete shade. In places where buildings don't block out the sun, big flat circles that look a little like large masses of lily pads will hang over walkways.
The town will encourage a pedestrian-orientated lifestyle, and only two-lane streets will be made to significantly reduce the number of vehicles and pollution.
The architects were not just thinking about environmental sustainability, when working on Xeritown, they were also thinking about social sustainability and how different types of families, people of different ages, different incomes and different ethnicities could live in harmony.
The architectural proposal was inspired by the country’s dramatic natural setting and the main goal was to create an organic skyline that merges buildings with the natural topography of the island.
The 10.8 million square feet eco resort, will be located in the bay of the capital city Baku, only a ferry ride away from a growing metropolis so dependent on oil and will set an example by making effective use of solar heat panels, photovoltaic cells, waste water and rainwater collection, and an offshore wind farm.
According to BIG, the development aims to be “entirely independent of external resources” an ambitious goal that will be achieved through a mix of traditional Azerbaijani building tradition and new technologies.

The city will be placed to take advantage of the cool sea breezes, while a perimeter wall around the entire city will protect buildings from the hot desert air and noise from the nearby Abu Dhabi airport.
Conceived as “an integrated city within a city”, 
Chicago-based 
Park Gate comprises six mid-rise towers that are arranged in facing pairs. A hanging garden canopy stretches between each set of structures, providing shade and cooling the neighborhood by as much as 10 degrees centigrade. 
The smooth curves of 1 Park Avenue evoke Dubai’s historic relationship with the Arabian Gulf. The 1,800 foot tower will incorporate solar panels, wind turbines, and a variety of other sustainable strategies in its design.
