Energy-efficient

Romanian non-profit green-tech firm Justin Capra Foundation for Sustainable Technologies and Inventions (or FITS), has unveiled the Soleta zeroEnergy range of sustainable off-grid homes. The flexible dwellings are available in several shapes and sizes, and combine rustic modular design with the proverbial kitchen sink of energy saving and producing technologies.  Read More

A US school has cut a six-figure sum from its winter energy bill by replacing its oil-burning boiler with woodchip biomass ones. The switch has reduced the school's carbon footprint by between 35 and 45 percent. The boilers are housed in a brand new green-roofed building which has become only the third LEED-certified power facility in the US.  Read More

In late March, all of the US Home Depot stores began carrying Cree’s new LED light bulbs. While they’re by no means the first such bulbs to offer the same form factor as standard incandescent bulbs, their combination of a relatively low price and visually-pleasing light quality have got some people – and not just publicists working for Cree – saying that they could be what finally brings LED light bulbs into the mainstream. I recently got a chance to try one out for myself, and I definitely liked what I saw.  Read More

Back-to-back announcements from Green Ray LED and Philips show signs that there is now clear water between LED lights and fluorescent lights so far as energy efficiency is concerned. The proverbial glow of commercially available lights with 200 lumens per watt efficiency can now be clearly seen radiating over the horizon.  Read More

Is this one of the world's best office buildings? These are the new offices of Norwegian oil and gas outfit Statoil, built at Fonebu near Oslo in Norway. The building was lauded well before its completion towards the end of 2012. In 2009 it was singled out as Future Project of the Year at the World Architecture Festival. Last year it received the Best Commercial Building prize at the World Architecture News Awards, and more recently was nominated in the Best Office & Business Development category at this year's MIPIM real estate exhibition in Cannes (where it was beaten by The Squaire in Frankfurt). So what's significant about the design?  Read More

By prioritizing energy minimization, and taking a pragmatic approach to materials and insulation, client Dr. Jung Soik and architect Yang Soo-in of Lifethings were able to construct a net zero energy house, or one that produces more energy than it uses, on a reasonable (if not meager) budget. Upon completion, Dr. Jung had spent US$284,000 on Sosoljip, the house which now stands at a fishing village four hours to the south of Seoul, South Korea.  Read More

Engineering firm ARUP has asked us to imagine the building of the future in its latest Foresight publication. In the article entitled “It’s Alive,” the design team envision a city building in the year 2050 that includes flexible modular pods, urban agriculture, climate-conscious facades and intelligent building systems. ARUP hopes the proposal will ultimately answer the question, "As city living takes center stage, what will we come to expect from the design and function of urban structures and buildings?".  Read More

Glass-skinned steel-frame skyscrapers have many advantages. They're relatively quick, inexpensive and easy to build and require comparatively few materials. But they pose problems; heat not least among them. Buildings with fully glazed facades are essentially greenhouses, so when the sun comes out, they can get uncomfortably hot. The problem that is more acute in hot climates like that of the United Arab Emirates, where, despite this fact, the appetite for glassy high-rise continues to be voracious. For its design of Al Bahr Towers in Abu Dhabi, Aedas has developed a unique intelligent skin, inspired by the traditional Arabic mashrabiya, that it claims reduces interior heat gains caused by sunlight by around 50 percent.  Read More
