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

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
In 1997, I helped my parents design and build their home. Early in the construction process, I had suggested that the house be built 25 feet back from where we originally had it planned, and that the fireplace be moved to the back side of the living room. We had already put the stakes in the ground and were ready to start digging for…Continue

What makes a Green Home green? Is it the bamboo floors? Maybe it’s the low-e windows or the extra insulation in the walls? What about a high efficiency heating and cooling system? Or maybe it's a plaque by your front door that says, “I'm Green!”?
How about all of the above and then…Continue

I was forwarded an email that originated from the Energy Star Heat Island group. This was something I was not aware of. I have changed the font to red for the main point of my own comments below the quoted part of the email.
"This call will provide an overview of the revised requirements for ENERGY STAR labeling of roofing products. The focus will be on the certification and verification processes. Beginning January 2011, labeling requires third- party…Continue
This week’s energy news looks bad for the United States – at first glance. The nation has slipped to second behind China in clean energy investment. Moreover, five of the G-20 nations have surpassed the US for clean energy investment relative to size of economy.
But look at little deeper into the report, “Who’s Winning the Clean Energy Race,” and you’ll see that the US did not slide in all forms of…Continue
