Green Building in India: NOT

There is a buzz about green buildings. But the question is: what does one mean by building green? And how does one design policies to make the green homes of our dreams?Green is not about first building structures using lots of material and energy, and then fixing them so that they become a little more efficient. Building green is about optimizing on the local ecology, using local material as far as possible and, most importantly, building to cut the power, water and material requirements.

via Green buildings: how to redesign | Centre for Science and Environment.

Sunita Narain makes some excellent points about building in India, and how western architecture influenced glass facades, closed buildings, etc. make little sense in India, and how traditional building concepts, optimised for local conditions would make more sense.

Two points:

  1. Traditional buildings are not necessarily optimised for density. To fit a lot of people in a little space, you need to build up. No, not 100s of stories, but fives and tens? It would be interesting to figure out that contradiction. But I’m no architect and I don’t know the answer
  2. The glass facade concrete skyscraper jungle look is associated with aspirational prosperity, ask any affluent Indian what they like about Hong Kong, or New York, or Singapore, and the shiny buildings will figure pretty high on the list after cleanliness and shopping. This is the kind of building associated with modernity and “class”. Making a sealed glass and concrete hell hole work in regions of high heat and humidity without large amounts of energy use for air conditioning is difficult.

It appears, though, that at least some people are thinking about this, as this book, helpfully titled Tropical Sustainable Architecture, would attest to.

BTW,
Sunita Narain’s editorials for the Down to Earth magazine are always thoughtful, and required reading for anyone interested in India’s development and environmental issues.

    Arsenic in the News

    Professor wins $1M for arsenic filter – Yahoo! News

    The National Academy of Engineering announced Thursday that the 2007 Grainger Challenge Prize for Sustainability would go to Abul Hussam, a chemistry professor at George Mason University in Fairfax. Hussam’s invention is already in use today, preventing serious health problems in residents of the professor’s native Bangladesh.

    This British Geological Survey website provides a good primer to the problem. Some key points:

    1. Arsenic is very toxic
    2. Arsenic is naturally occurring in the shallow groundwater aquifers of Bengal and Bangladesh at a toxic level
    3. The surface water is contaminated with bacteria and was responsible for high infant mortality, so aid agencies in the ’70s encouraged the use of tube wells and other groundwater pumps. While this contributed to a decline in infant mortality from gastrointestinal infections, it also dosed unsuspecting people with disease causing levels of arsenic
    4. The technology for removal of arsenic is very well known. But most solutions require electricity/periodic maintenance/technical skills and are thus not universal or sustainable.
    5. Simplicity is the key. You can’t tell the people to not drink the water, it is the only clean water available. You can’t install water treatment plants, there is no running water, you can’t rely on solutions that are centralized.

    So with all that in mind, here’s what Prof. Hussam did:

    The Gold Award-winning SONO filter is a point-of-use method for removing arsenic from drinking water.  A top bucket is filled with locally available coarse river sand and a composite iron matrix (CIM).  The sand filters coarse particles and imparts mechanical stability, while the CIM removes inorganic arsenic.  The water then flows into a second bucket where it again filters through coarse river sand, then wood charcoal to remove organics, and finally through fine river sand and wet brick chips to remove fine particles and stabilize water flow.  The SONO filter is now manufactured and used in Bangladesh. That’s great, and easy!

    That’s pretty much freshman chemistry right there, further proof that most innovation does not need new science, only people willing to spend some time on problems that don’t necessarily get looked at.

  • Goldman Prize – The Green Nobel – Google Earth Narrative

    This is very inspiring, and wonderful to watch.

    The Goldman Prize has developed a tour that uses 3-D Google Earth imagery to tell the stories of the 2009 Prize recipients. Narrated by Robert Redford, the tour allows viewers to travel the world, visiting huge mountaintop removal mines, ship breaking yards and other locations where the Prize winners live and work.

  • Drugs in the Water

    When researchers analyzed vials of treated wastewater taken from a plant where about 90 Indian drug factories dump their residues, they were shocked. Enough of a single, powerful antibiotic was being spewed into one stream each day to treat every person in a city of 90,000.

    And it wasn’t just ciprofloxacin being detected. The supposedly cleaned water was a floating medicine cabinet — a soup of 21 different active pharmaceutical ingredients, used in generics for treatment of hypertension, heart disease, chronic liver ailments, depression, gonorrhea, ulcers and other ailments. Half of the drugs measured at the highest levels of pharmaceuticals ever detected in the environment, researchers say.

    Not at all surprising, considering that drug manufacturing releases tons of pollutants at high concentrations. The sources are very different from recent studies in the US where end users of the drug are the greatest source, and ciprofloxacin was again one of the drugs detected at the highest levels. At this rate, most bugs will be resistant to cipro in a few years.

    In the end, water treatment plants cannot deal with this toxic soup. They need to be cleaned up at the source, by the pharmaceutical companies before they hit any waste streams. After all, isn’t recapturing and reusing the kilos of drugs being wasted good economic sense?

    Senate 1, Plutocrats 2

    It was a close game. But in the end, the plutocrats prevailed on energy legislation. Yes, fuel economy will go up some, but the push towards renewable energy will have to wait. Even on fuel economy standards, the requirement to incrementally increase standards every year after  getting to 35 mpg by 2020 was dropped.

    Well, given the notoriously undemocratic nature of the US senate, progress will be slow.
    Senate Adopts an Energy Bill Raising Mileage for Cars – New York Times

    The Senate passed a broad energy bill late Thursday that would, among other things, require the first big increase in fuel mileage requirements for passenger cars in more than two decades. The vote, 65 to 27, was a major defeat for car manufacturers, which had fought for a much smaller increase in fuel economy standards and is expected to keep fighting as the House takes up the issue. But Senate Democrats also fell short of their own goals. In a victory for the oil industry, Republican lawmakers successfully blocked a crucial component of the Democratic plan that would have raised taxes on oil companies by about $32 billion and used the money on tax breaks for wind power, solar power, ethanol and other renewable fuels. Republicans also blocked a provision of the legislation that would have required electric utilities to greatly increase the share of power they get from renewable sources of energy. As a result, Senate Democrats had to settle for a bill that calls for a vast expansion of renewable fuels over the next decade — to 36 billion gallons a year of alternatives to gasoline — but does little to actually promote those fuels through tax breaks or other subsidies. The combination of breakthroughs and setbacks highlighted the blocking power of the entrenched industry groups, from oil companies and electric utilities to car manufacturers, that had blanketed Congress in recent days to defend their interests.

  • Coal-to-Liquid: Useless

    Liquid transportation fuels derived from coal and natural gas could help the United States reduce its dependence on petroleum. The fuels could be produced domestically or imported from fossil fuel-rich countries. The goal of this paper is to determine the life-cycle GHG emissions of coal- and natural gas-based Fischer−Tropsch (FT) liquids, as well as to compare production costs. The results show that the use of coal- or natural gas-based FT liquids will likely lead to significant increases in greenhouse gas (GHG) emissions compared to petroleum-based fuels. In a best-case scenario, coal- or natural gas-based FT-liquids have emissions only comparable to petroleum-based fuels. In addition, the economic advantages of gas-to-liquid (GTL) fuels are not obvious: there is a narrow range of petroleum and natural gas prices at which GTL fuels would be competitive with petroleum-based fuels. CTL fuels are generally cheaper than petroleum-based fuels. However, recent reports suggest there is uncertainty about the availability of economically viable coal resources in the United States. If the U.S. has a goal of increasing its energy security, and at the same time significantly reducing its GHG emissions, neither CTL nor GTL consumption seem a reasonable path to follow.

    Comparative Analysis of the Production Costs and Life-Cycle GHG Emissions of FT Liquid Fuels from Coal and Natural Gas.

    To summarize, no cost benefits, increased GHG emissions, a lot of uncertainty, let’s not follow this madness of trying to make coal into gasoline.
