Energy-saving

It won first prize in the Affordability category of the 2011 Solar Decathlon, and in December of 2012 Empowerhouse became Washington DC’s first Passive House. In a video interview just released by the US Department of Energy, its new owner describes how the house's energy-saving design means a brighter future for her family.  Read More

The Illawarra Flame house was created by students from the University of Wollongong

A group of students from the University of Wollongong took a typical Australian "fibro house," and retrofitted it with technology which includes solar panels, climate control, and an energy monitoring system. The end result, dubbed Illawarra Flame, is a net-zero home which offers a potential starting point for transforming many similar properties into low-energy dwellings.  Read More

A new lightweight hoisting line known as UltraRope could double the current maximum height...

As architects continue to design taller and taller buildings, a certain limitation of elevators is going to become more of a problem – using traditional steel lifting cables, they can’t go farther than 500 meters (1,640 ft) in one vertical run. Any higher, and the weight of all the cable required is simply too much. Currently in the world's few buildings that are over 500 meters tall, passengers must transfer from one elevator line to another, part way up. Thanks to a new lightweight material known as UltraRope, however, elevators should now be able to travel up to one kilometer (3,281 ft) continuously.  Read More

The Soleto zeroEnergy One home

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

Philip's Coen Liedenbaum shows off the 200-lm/W prototype LED tube

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

Just over a week ago we reported that Philips' 22 W LED light bulb, designed as a like-for-like replacement of a 100-W incandescent light bulb, was the first LED bulb of its type to receive the stamp of approval from Energy Star. But looking at the Energy Star requirements reported by Philips in its press release, it seemed a little strange that Philips' product is the only one to have been certified – given that products long on the market appear, at face value, to meet those requirements. Since then, Gizmag has spoken to LED light bulb makers Switch Lighting and other industry players to find out why they're apparently playing catch-up.  Read More

The Wattio system is a four-component package comprised of a POD, THERMIC, GATE and BAT (I...

Here at Gizmag we've featured a variety of home energy management devices, and the latest solution is an offering from Spanish startup, Wattio. The SmartHome 360º is a home energy monitoring and control system that can be managed through a smartphone, tablet or PC using the Wattio Gateway software. The system's four components are capable of communicating with each other and subsequently with the Wattio software applications and cloud service, to provide comprehensive energy management capability throughout the home.  Read More

The house is “floated” on 60 foot (roughly 18 meter) steel stilts, supported by concrete p...

Alongside the use of sustainable building materials, and innovative energy-saving techniques, another step in reducing a new home’s impact on the environment can be to build upon land once considered undesirable for human habitation. The “Like a Houseboat” property by Shipley Architects ticks all three boxes, with steel stilts enabling the single-family residence to be built upon poor-quality soil once home to a landfill.  Read More

Pit Homes were used by some Native American tribes

Edgeland Residence is a modern dwelling designed by the Bercy Chen Studio which sees the company rehabilitating land once considered unsuitable for occupation. Claimed to set a new standard for sustainability, it draws inspiration from the Native American Pit House, and is designed to impact the environment as little as possible.  Read More

Researchers at FMTC reduced the power consumption of their badminton robot by 50 percent, ...

Eco-friendly refrigerators, dishwashers, and laundry machines don't just save you money – they're also better for the environment. Factory automation could reap the same rewards, but optimizing production lines isn't easy. That's where the energy efficiency analysis software, developed by the EU-funded Energy Software Tools for Sustainable Machine Design (ESTOMAD) project, enters the picture.  Read More
