The last several weeks I've written about a number of common myths of green building. (Last's week's myth: solar panels are the best way to green a home.) Here's another: that the energy-conservation features and products we install are enough to ensure that our houses will be top energy performers. The starting point in greening a home should...

Geoengineering. That's what they're calling some of the more high-tech proposals for solving the climate crisis. Geoengineering strategies all involve intentional manipulation of the earth's climate in order to offset the effects of anthropogenic greenhouse gas emissions--for example, installing orbital mirrors in space, artificially "enhancing"...

Colors ‘n Curves: A new bank headquarters in Frankfurt may well be the world's most energy-efficient office tower.

April 2, 2010

By Ulf Meyer

 

Shrouded in shades of many colors, it is a building that claims to be green. And so it is. It is not often that a midsize bank building has good reason to make that claim, but the new 400,000-square-foot, $85 million expansion of the headquarters for the KfW Bank in Frankfurt, designed by Sauerbruch Hutton...

An article in the UK version of Wired talks about a design for a skyscraper that would collect water in much the way plants do. The skin of the building collects rainwater, guiding it to storage cisterns below ground. It could then be used for toilets, irrigation, clothes washing, and other uses for which potable water is not required.... Read more

Chilled beams are ceiling-mounted fixtures that use chilled water flowing through finned heat-exchanger coils to supply cooling, and sometimes heating, in commercial buildings. They are available in a variety of styles, typically in one- or two-foot widths (0.3 or 0.6 m) and in lengths up to ten feet (3 m).

Passive chilled beams operate through... Read more
