Zero-Emissions City in the Desert

In my visit to MIT earlier this week I heard of MIT’s participation in Abu Dhabi’s green metropolis.  Here is the article in Technology Review.

Energy surplus: Masdar headquarters, shown in an architectural rendering, is designed to generate more renewable electricity than it consumes; it would be the first large-scale, multi-use building to do so.

The city will be an oasis of renewable energy in a country of five million, made rich by oil, that consumes the most natural resources per capita in the world. Seen one way, it's just the latest ostentatious project in a country that's been defined by them. Indeed, the UAE is already home to the world's tallest building and an enormous indoor ski facility that features a 200-meter-long black-diamond slope. Real-estate developers have dredged coral and sand from the sea floor, piling it up in the Persian Gulf to create islands in the shape of palm trees and a map of the world.

Yet many experts are optimistic that the city can become a test bed for new approaches to the engineering and architectural problems involved in creating environmentally sustainable cities. Although architects have already designed and builders constructed many small zero-emissions residences and commercial buildings, projects involving large, multi-use commercial buildings have fallen short of expectations, using too much energy or failing to generate enough. Part of the problem is the growing complexity that comes with scale, says J. Michael McQuade, senior vice president of science and technology at United Technologies in Hartford, CT; today's design software hasn't been able to handle it. But Masdar City, itself developed with the help of extensive modeling, will be wired from the beginning to collect data that could prove valuable for developing better models. That information could make future zero-emissions cities cheaper and easier to build.

Why?

And the development is meant to make money, not just introduce new technology. "We want Masdar City to be profitable, not just a sunk cost," said Khaled Awad, the project's director of property development, at a huge real-estate exhibition in Dubai last fall. "If it is not profitable as a real-estate development, it is not sustainable." Yet if it is, it may be replicable.
