A positive energy building is one that produces more power than it consumes (yes they have been around for a while). The Masdar Headquarters in Abu Dhabi – due for completion in 2010 claims that it will be the first to do this on a substantial scale (mainly thanks to use of solar energy). David Fisher's spectacular “Dynamic Architecture” building in Dubai will aim to achieve the same goal using wind. Scaling up on the ambition stakes France has pledged all of its new housing will fit into this category by 2020.

The Solar Decathlon is a just-completed competition in which 20 teams of college and university students competed to design, build, and operate the most attractive and energy-efficient solar-powered house. View a photo gallery or take video tours of the homes. Inhabitat has been blogging the event - here's their view of Germany's winning entry.

Passivhaus/Passive house design that saves mucho energy, does not require air conditioning, does not require heating even when outdoors it's 10 below! Since, for example, more than 30% of energy consumed in the UK is for homes and 82 per cent of that is space and water heating, [Monbiot, "Heat,"chapter 5, "Our Leaky Homes,"] changing our standards of home design is important. Diagram shows that basic solar design concepts are well understood and technically easy to implement in new construction. [If only my house could be turned 45 degrees!] Possibly through ignorance, and partly through the desire to cut corners instead of doing things right, we do not make these wise concepts a priority. There are lots of cool alternative building techniques, many of which are traditional and being revived. This leading design standard saves 90% of energy used in the home. Here in Canada it's called the net zero energy home.

Another way to save energy: make every day a Daylight Savings Time day. Why *do* we (USAians or anyone else with daylight-extending customs) bother to change back to standard time, anyway?
