Talk about a light bulb moment.
A professor of engineering at Edinburgh University recently demonstrated for the first time to a wide audience his technology that uses common every day lights to transmit data.
Harald Haas streamed a video through a desk lamp at Ted Global 2011at Scotland’s Edinburgh International Conference Center in July.
If commercialized, the technology not only creates a vast new application for light, but also dramatically expands our now limited…Continue

The candle has been around the cave and the realm of weatherization and energy efficiency for some time now, but here’s an app which few have ever conceptualized.
In the early days of weatherization, before the thermagraph, even before the blower door, the trusty candle provided us several enlightening concepts. It would flicker when breezes brushed against its flame as a clear indicator of infiltration. Before the fancy schmancy digital manometers, a few old timers would…Continue
This blog is cross-posted with Remodeling Magazine with the kind permission of the editor.
Let me recommend an excellent, well-written blog indeed. Melissa Baldridge goes well beyond the nuts-and-bolts conversations in which we so often engage, and she presents ideas from a broader perspective. At the point where remodeling meets building performance, the industry necessarily concerns…Continue
Here’s something you don’t hear people complain about much these days: worker shortages. That is, unless you’re in energy efficiency, an industry that is booming as others are busting.
Sixty percent of those responding to a recent survey by the Association of Energy Services Professionals cited a lack of talented workers in energy efficiency.
“Energy efficiency is a rapidly growing segment of the overall energy industry and we…Continue

At the recently concluded ASHRAE Winter Meeting in Montreal, significant changes occurred to the development of the ASHRAE 90.2 standard (ASHRAE 90.2 is the companion standard to ASHRAE 90.1 and applies primarily to residential dwellings). Prior to the…Continue

It’s easy to lose the longer perspective when we are involved in day-to-day efforts to save energy. That’s why I want to focus on a single home—Danny Parker’s house in Florida—to illustrate the bumpy road to zero energy use. The figure on the right shows 21 years of electricity use, along with many of the major events in Danny’s household. (Follow the green…Continue
Who doesn’t pat themselves on the back when Google puts money into their industry? Ah, the giant likes this market. I must be on the right track!
So what does it mean now that Google has announced it will retire its Google PowerMeter because it didn’t catch on? Are all those companies who are investing in smart grid on the wrong track?
Clearly not. Google had star quality…Continue
Once a month or so Marie and I have dinner with a group of old friends, all of whom happen to be particularly interested in theater and other creative arts. The subject of architecture in general and Frank Lloyd Wright in particular popped up during one such recent gathering over Indian food. Our friends burbled enthusiastically about their past visits to various Wright buildings and how beautiful they are.
I got into trouble when…Continue
Below is an article I wrote on the Mapawatt Blog. I thought I would share it here on Home Energy Pros as well. Are you preparing your home for an electric car?
As my electric Porsche…Continue
The title of this blog might strike you as kind of weird, especially this week. After all, the Electric Power Research Institute made the news with a study showing that smart grid is going to be far bigger than we first thought.
Smart grid in simplest terms brings to the electrical grid the digital intelligence of computers and the Internet. Just seven years ago EPRI expected smartening the grid to cost $165 billion. But its new…Continue

First off, there is no law actually calling for the death of the incandescent. The Energy Independence and Security Act of 2007 actually states…Continue
In my last four HVAC Design jobs, I've specified ductless mini-split heat pumps. I have four more such jobs underway now.
My recent visit to Savannah for the USGBC's green product expo charged up my historic preservation bug and got me to thinking about how to apply building science to historic buildings.
Most of us that have ever lived in, owned, or even just visited a historic home…Continue

Few countries have been dealt such a tragic combination of natural and manmade disasters as Japan. The part of the disaster that I understand is the shortage of electricity. I wrote a book, Saving Electricity in a Hurry, in 2005 while working at the International Energy Agency.1 In the book, I explained the measures that a government must take in order to quickly reduce electricity demand while protecting…Continue

I interviewed architect Chris Laumer-Giddens, of Energy Vanguard, on the company's new integrated design-build / home-performance model last week. I'm reposting the interview here, with Chris's permission. -- Leah Thayer, daily5Remodel…Continue
We all go through transitions in our lives. One of the biggest is choosing or changing a profession. As I mentioned in previous entries, my background for the previous 9 years was doing class action and warranty inspections on residential building products. This meant I became keenly…Continue
