What is a B.I.Q. Building, and How Does It Being Covered in Algae Save Energy?

germany

A new apartment complex in Hamburg, Germany, intends to generate heat, as well as revenue, from growing the micro-organism. The five-story Bio Intelligent Quotient (B.I.Q.) building, which was expected to become fully operational on Wednesday, has a high-tech facade that looks like a cross between a Mondrian painting and a terrarium but is actually a vertical algae farm.

The designers of the B.I.Q. building, which relies entirely on renewable energy, promise that their pioneering energy system will harvest fast-growing algae to create biofuel, produce heat, shade the building, abate street noise and make history.

Lukas Verlage, managing director of the Colt Group, part of the high-powered consortium that constructed the energy system, said in an e-mail that the building was “an outstanding and important development in the use of renewable resources in building technology,” comparable to advances in the space program.

Jatropha: The Green Fuel is Awash in Red Ink

Money may not grow on trees, but for a time it appeared to grow on bushes – specifically, a tropical shrub called jatropha curcas.

Over the past decade, jatropha was planted on millions of acres across Asia and sub-Saharan Africa after research showed that oil from its crushed seeds makes an excellent biofuel. Because jatropha can tolerate dry, rocky soil unsuited to agriculture, boosters said, subsistence farmers could grow it as a cash crop without denting food production. And with governments worldwide pushing renewable fuels, investors in jatropha-oil ventures looked set to win, too.

So far, the jatropha boom has produced more losers than winners. Many projects have foundered as seed production has failed to meet expectations, and India, China and other countries have scaled back plans for additional planting. Farmers have discovered that while jatropha can indeed grow on barren land, it doesn’t flourish there, says Promode Kant, director of the Institute of Green Economy in New Delhi and co-author of a report titled “The Extraordinary Collapse of Jatropha as a Global Biofuel.”

Says Kant: “Without moisture it does not seed, or it seeds extremely poorly.”

Green Economy Resilient, Growing Quickly, Report Says

Since the mid-1990s, green jobs in San Diego County have grown more than twice as fast as the overall average and weathered the past two recessions better than most other industries, according to a report released Tuesday by Next10, a research organization focused on the environmental industry.

According to the report, there were 20,500 “green economy” workers in San Diego County at the beginning of 2010 — the most-recent year for comprehensive data — compared to just 12,400 in 1995.

Those jobs — including solar-panel installers, wind-turbine manufacturers, biofuel developers, energy conservation consultants, recycling collectors, wastewater processors and “clean-building” designers — grew at an average pace of 4 percent per year, compared to 1.8 percent for the overall workforce.

Even at the depths of the Great Recession, green jobs held steady in San Diego County. Only 300 jobs were lost — a 1 percent drop in employment — that compared to a 4.5 percent drop in the county’s total workforce.
