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…

The Bumpy Road to Net Zero Energy

By Alan Meier

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…

Codes, Ignition Barriers, Foam Products, Manufacturer's Installation Specs

In the housing retrofit and energy upgrade world, we use lots of foam products, don't we?  Did you know that some products may not be used in certain areas of houses? Codes and product manufacturers specify what can be used where, and when an ignition or thermal barrier must be used to cover the product in order to meet codes and protect occupants in the event of a fire.  Read all about our research at www.PureEnergyCoach.com and click on Quality… Continue

Google quits smart meters. Anyone care?

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…

So Long, Frank Lloyd Wright



     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.

The Ductopus or the Centipede - Which HVAC Duct System Is Better?

I've been thinking lately that I might be in danger of losing all my friends in the HVAC business because I've been a bit heavy on showing examples of what they get wrong but not so good at showing what they do well. If you read my article… Continue

Looking forward to the day smart grid dies

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…

No Carts Before Horses - Design for Energy Efficiency Early

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.

What Tokyo Must Do

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…

I’ve just returned from a week-long trip to Cuba with a group of twenty other energy professionals sponsored by Solar Energy International andGlobal Exchange. The purpose of the trip was to explore…

Why I Love My Job

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…

No More "Damn Architects!" - The Case for Integrated Design

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…

A Green Home - It's Just Good Design

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…

New Energy Star requirements for Cool Roof coatings

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…

US at top worldwide in EE innovation

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…

Putting Mercury in CFLs in Perspective

This is an updated version of the post that originally appeared here.

I'm a fan of CFLs, but I can understand how the small amount of mercury in them can worry some. If you're worried about the tiny bit of mercury in CFLs, I can't tell you one way or another how to decide for your home, all I can do is give you the facts that are available, and let you make your own decision.… Continue
