HUGE Solar Roof

- Adam Clare

PGIGrup is about to make Europe’s largest solar roof. The building is going to be built in Madrid and generate 3 megawatts of electricity.

At over a kilometer in length, the rooftop will have an area of over 57,000 square meters, of which 21,000 will be occupied by solar panels. The power installed will be of approximately 3 MW peak, which will generate over 3.6 GWh per year.

It is predicted that this design will enable it to save 15% on climate conditioning in winter, and 34% in summer, as well as saving on lighting. The facade of the office blocks is a double skin, where the external glass is hung out from staggered glass fins.

Thermal Inertia for Free Heating and Cooling

How does not needing an air conditioner or a furnace sound? To me, it sounds great.

The Enertia home uses thermal energy to cycle cooling and warming the house. It achieves this by delaying the thermal patterns of the planet, it’s like slow motion but in real life.

Once completed, even before you move in, these new homes will have come alive with a natural atmospheric cycle, like the Earth, on which they are based. A built-in “biosphere,” in gradual but constant motion, draws energy from the sun, and geothermal stability from the ground, creating a temperate climate that buffers the primary living space.

Solar in Seville

The wonderful inhabitat has a post all about the solar generating that’s happening in Seville.

This tower, while not a new technology (see CESA-1), is part of a series of projects whose final aim is to provide enough green energy for 180,000 homes, or most of the population of Seville. The final project, able to produce over 300MW, will include a series of towers, two more of which are being built, and standard photovoltaic power plants, as well as a mixture of newer parabolic solar collectors which will be installed at a later stage. The entire power plant will be operational by 2013. And here’s the most impressive part. The entire development, once it’s operational, will generate zero greenhouse gas emissions.

Spin-Powered Office Towers

- Adam Clare

EcoGeek has the lowdown on a high-rise design that supposedly can power itself and up to ten other office buildings. The tower is designed to have spinning floors and will act like a giant windmill, don’t worry all the essentials like elevators are in a central non-rotating concrete core. A neat idea, but one that I do question.

The video shows the spinning in action:

iSave Shower Power

- Adam Clare

I’m a sucker for nice long hot showers and I can’t help but think that it’s wasteful and an exercise of pure luxury that a lot of the world can’t afford. This all doesn’t stop me from spending 10 minutes enjoying hot water. A new invention may help me ween off my wastefulness though.

The iSave is a shower head (or a faucet fixture) that tracks how much water you’re using. It’s powered by the water itself, genius!

neat-o
