This simple and sustainable design for the tropics is by Foster + Partners. Like their new design for Heathrow Airport it uses an undulating design for the roof.

I love eggs, and not just because I love the way they taste. Of course, part of my eggophilia is also due to the fact that eggs are an affordable, high-quality protein, usually costing less than twenty cents apiece. Despite much publicized cholesterol warnings, more and more research is revealing the many health benefits of eating eggs — everything from strengthening muscles to improving brain function — with most research now showing that an egg or two a day is just fine for most people.
Plus, eggs have clever packaging. I hate paying for packaging, but when it comes to the uber-chic engineering marvel known as the eggshell, I don’t mind the cost. Madison Avenue marketing gurus or MIT engineering professors could never design packaging as cool and functional as the eggshell. If eggs didn’t come in their own shell we’d probably package them in some form of plastic, which might be recyclable, but would never have the multitude of reuses attributable to Mother Nature’s own packaging.
Take a crack at these eggshell reuses:
1. Compost for Naturally Fertilized Soil
Eggshells quickly decompose in the compost pile and add valuable calcium and other minerals to the soil in the process.
2. Nontoxic Pest Control in the Garden
Scatter crushed eggshell around your plants and flowers to help deter plant-eating slugs, snails and cutworms without using eco-unfriendly pesticides. Also, deer hate the smell of eggs, so scattering eggshells around the flowerbed will help keep Bambi away from your begonias.
3. Less Bitter Coffee
Add an eggshell to the coffee in the filter, and your morning coffee will be less bitter. The spent coffee grounds, eggshell and bio-degradable filter are then conveniently ready for the compost pile.
4. Splendid Seedling Starters
Fill biodegradable eggshell halves with potting soil instead of using peat pots to start seedlings for the garden. And an egg carton on the windowsill is the perfect way to start a dozen tomato seedlings in shells before transplanting to the garden in the spring.
5. Eco-friendly Household Abrasive
Shake crushed eggshells and a little soapy water to scour hard-to-clean items like thermoses and vases. Crushed eggshells can also be used as a nontoxic abrasive on pots and pans.
6. Eggy, Crafty Projects
“Blow out” the inside of a raw egg and paint/decorate the hollow shell to make your Faberge eggs or other craft projects. Pieces of egg shell (plain or dyed) are also used in mosaic art projects.
In a stark contrast with how construction used to be thought of, the green building movement has been a shift away from the traditional concerns about money and time. The betterment of our planet, as it turns out, is quickly becoming a bigger priority. Since March of this year, the Leadership in Energy and Environmental Design (LEED) program has seen around 20,852 new LEED registered and certified projects.
Most of this can be attributed to the fact that builders view green buildings as more economical in the long run, and recent incentives on the part of the government have added an extra encouragement. But while these positives have been talked about pretty often, there are some risks associated with going green that still leave many builders wary.
