Moving back to my native New Zealand this year, I had the chance to try a different kind of heating system for our house here. One of the most intriguing technologies I’m hearing about here is something I never heard of – an air heat pump.
I was familiar with the very eco correct “geothermal” or ground heat pump, only because I write about green building. This pumps air through pipes that loop through your house and down about 5 feet underground where the temperature is a relatively constant 55 degrees F, summer and winter, from Maine to Miami, bringing up a moderate temperature, even though above-ground temperatures can veer from below 0 to over 100 through the seasons. Staying at a moderate 55 F year round makes it a lot easier to make up the difference (with heating or cooling) to the comfortable 65 or so that we humans evolved to like best.

Noise from wind turbine blades, inadvertent bat and bird kills and even the way wind turbines look have made installing them anything but a breeze. New York design firm Atelier DNA has an alternative concept that ditches blades in favor of stalks. Resembling thin cattails, the Windstalks generate electricity when the wind sets them waving. The designers came up with the idea for the planned city Masdar, a 2.3-square-mile, automobile-free area being built outside of Abu Dhabi. Atelier DNA’s “Windstalk” project came in second in the Land Art Generator competition a contest sponsored by Madsar to identify the best work of art that generates renewable energy from a pool of international submissions.

Industrial designer Jonathan Globerson has one of those ideas that makes you go, "Oh, duh! Why don't we all have one yet?" It's so simple, and yet so smart. His Greenerator design is a personal generator that converts wind and sun to power and can do so from a balcony, without messing with the view.
What is LEED? How does it work? and, what is LEED Credential?
