Scientists at Michigan State University announced this week the creation of a “transparent luminescent solar concentrator” that could turn windows and even cellphone screens into solar-power generators.
This technology could mean that one day entire skyscrapers might be able to generate solar power without blocking out light or ruining tenants' views.
The material works by absorbing light in the invisible spectrum (ultraviolet and near infrared) and then re-emitting it in the infrared. The infrared light is then channeled to the edge of the clear surface, where thin strips of photovoltaic cells generate the power.
Because we cannot see infrared or ultraviolet light, the material remains transparent even while concentrating sunlight. Previous luminescent solar concentrators have been developed, but they emitted light in the visible spectrum, creating a stained-glass effect.
“No one wants to sit behind colored glass,” Richard Lunt, who leads the lab researching this new technology, said in a press release. He likened the experience to “working in a disco.”
The new technology is promising, but needs to be made more efficient. Researchers say that the solar conversion efficiency is around one percent. Ideally, this could be increased to more than five percent. The researchers note that the highest conversion efficiency achieved by a non-transparent luminescent solar concentrator is about seven percent.
While writing this post, I had 18 tabs open. I’d like to say they were all for research, although I’m pretty sure one or two slipped down a YouTube wormhole.
Does this sound familiar?
It seems like my multi-tab madness is right in line with the status quo. We all love to have multiple tabs open at once, adding more and more as we find new articles to click and sites to visit. Pretty soon, it’s likely we’ve forgotten what we were online for in the first place.
We often get asked by owners whether they should obtain a warranty or a maintenenace agreement for their HVAC system. The answer is: get both. Here's why. (Should I Get A Warranty Or Agreement On My #HVAC System?
“The Building Technologies Office (BTO) works with the commercial building industry to accelerate the uptake of energy efficiency technologies and techniques in both existing and new commercial buildings. By developing, demonstrating, and deploying cost-effective solutions, BTO strives to reduce energy consumption across the commercial building sector by at least 1,600 TBtu.”

The Australian solar industry is preparing for what it calls a “David and Goliath” battle against the country’s biggest generators and network operators. The outcome will likely decide the immediate fate of rooftop solar in Australia, and the pace of the so-called “democratisation of energy” — a contest that pitches households and their solar modules against the centralised utilities that have dominated the industry for a century or more in Australia and across the developed world.

It's simple, you want to get the right type of lighting, period. As a building owner you don't want to spend money and not get results, so getting a better understanding of the technical aspects behind your lighting project is in your best interest.
This is a guest post by James Lawrence Powell.I have brought my previous study (see here and here) up-to-date by reviewing peer-reviewed articles in scientific journals over the period from Nov. 12, 2012 through December 31, 2013. I found 2,258 articles, written by a total of 9,136 authors. (Download the chart above here.)Only one article, by a single author in the Herald of the Russian Academy of Sciences, rejected man-made global warming. I discuss that article here.Click headline to read more--

Sustainability managers, engineers, architects, developers and consultants met in Dubai for the BGreen Seminar series the day after the announcement that the city would host Expo 2020. And as the construction industry prepared for the new shot in the arm, it added an extra dimension to the two seminars: Energy Efficiency Early in Construction and Internal Air Quality.

If, after sitting for hours in a stuffy, crowded meeting room or classroom, you've found yourself thinking a little more slowly than usual, it may not have been your imagination.
An emerging body of research is indicating that the high levels of carbon dioxide and other indoor pollutants that we face in poorly ventilated rooms reduces our cognitive performance and decision-making ability.
Energy efficient lighting reduces the electricity demand and is a cost effective method of lighting system compared to conventional lighting methods.In trending years, the gap between power generation figures and demand figures is a matter of concern, as it implies the failure of power supply system to meet the power demand, thus a warning about lack ofconservation of energy.“”
The best perk of working remotely just might be the peace of mind it brings. The ability to skip the stressful morning commute, roll out of bed, and jump onto the computer can make you feel infinitely more productive. "I work all the time--remotely. But I don't feel like a workaholic and I'm not going to burn out. This is the great privilege of running a remote business," Betabeat editor-at-large Ryan Holiday wrote in a recent post. Holiday runs the marketing company Brass Check, and for the past three years he's lived in four cities and hired remote employees in at least five different states.

An energy audit can help homeowners and owners of multifamily buildings determine how to better keep a property warm in the winter and cool in the summer by tightening the building's envelope. The fixes typically cost a few thousand dollars, and area utility companies offer rebates tied to the work.
You can save money and energy while lighting your home and still maintaining good light quantity and quality. Consider energy-efficient lighting options to use the same amount of light for less money. Learn strategies for comparing and buying lighting products and using them efficiently.
