Energy efficiency and Weight Watchers

We’ve been hearing for years that the energy efficiency industry needs to find its equivalent to the cell phone. These days industry folks refer to it as the ‘killer app,” the revolutionary product or service that consumers can’t resist.

But lately, partly because I’m dieting, I’ve been thinking what energy efficiency really needs is something akin to a Weight Watchers dessert.

Let me explain…

When you absolutely, positively NEED to get efficient overnight!

Every once in a while, we have an experience that completely crumbles some long-standing preconceived notion, and this week I’m pleased to share my revelation with you. 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…

Bringing Design/Build to Home Performance

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…

Willowside Rd., Day 14

John and Jane Doe's report is basically written. I have a template that I use that has been slowly built and improved over the past projects. It's a fine start but still requires a fair amount of custom writing, since each house has enough unique issues that need to be addressed.  There's report software out there such as Recurve's, EAI, or BizEE, but none have that personal touch that comes from a written report.  So here's some items from the report:





Target Infiltration: 0.25… Continue

100 Homes and Counting...

On April 15, 2011, Homes for Our Troops, a national nonprofit, nonpartisan organization founded in 2004 that's dedicated to helping veterans who have returned home from combat with serious disabilities and injuries since September 11, 2001, kicked off the build of its 101st home in Fredericksburg, Virginia. Homes for Our Troops is building this particular home (see photo) for U.S. Army Sergeant Jude Recendez who lost both of his… Continue

Willowside Rd., Day 10, part 2

OK, I'm back from getting the dimensions of Doe's house, enter all the information into EnergyPro, and do an initial calculation. It looks like the house as it is has a HERS of 147, which means that the model predicts that it will use about one and a half times as much energy as a 'reference home', which is this exact same home if it was built to today's energy code requirements and has by definition a HERS of 100. 147 is not too bad but way above what we want. Let's see if we can get it below… Continue

Willowside Rd., Day 10

Well, it's taking a bit longer to get to John Doe's report than I'd expected and I've one molar less than a few days ago and a big hole in my jaw.  But, here we are.



I use EnergyPro because I learned it some years ago and I'm familiar with it. Plus, it's the one that's accepted by EUC (Energy Upgrade California), which I plan on applying for this project. Looking over the audit form, everything looks good. We should be able to easily improve Doe's house enough to get a couple of… Continue

ACCA Existing Residential Building Improvement Standard: Some Thoughts

My company, Building Efficiency Resources  (www.TheBER.com) is--among other things--a HERS providership.  We see a tremendous opportunity now and into the future for Raters on the retrofit side, and we are devoting considerable effort to exploring and developing ways for our Raters to seize that opportunity.  We bring to that task a clear understanding that not all Certified Raters are highly knowledgeable about existing homes, and that the farther back we…

Willowside Rd., Day 7

Note: the following is not a comprehensive listing of all the details involved in a full audit.  It's meant to be a general description of the process so please don't think that you can read this and do one yourself.  Your and the homeowners' safety requires a full Building Performance training, at a minimum.

 



John and Jane are delightful. Pretty… Continue

Willowside Rd., Day 6

The batteries are charged, camera's in the truck, and the blank forms are in the briefcase.  Two of us will arrive at John Doe's at 8:30 tomorrow - Wednesday - morning.  It should be a brisk and partly cloudy day, enough difference between inside and out to get good, clear IR camera pix.  First a short sit-down with the owner, then quick walk through with the camera, a Worst Case Combustion Zone test (let me know if you want more info on that; I'm may write a post about why it's vitally… Continue

What's Denver doing on the EV-Ready list?

Guest Blog by Cara Miale

April 20, 2011

Looking at the list of the most EV-ready cities just released by Ford, it’s no surprise many of them are coastal. On the east and west coasts energy is pricey, so the pressure is on to achieve innovation that will control costs and reduce dependence on fossil fuels.

But what’s up with Denver out there in the middle of the map, all by its…

Willowside Rd., Day 2

I caught up with John Doe while he was on the way to work this morning, apologized for not getting back to him last night, and checked in about Tuesday of next week, April 12th, for his test-in Audit.  The weather forecast is for a perfect day: cool and clear, which should allow distinctive IR photos of air infiltration pathways during the blower door test.



I stopped in at Harmony Farms, my favorite farm & garden store, on Hwy 116 this afternoon to talk to Ali Ghorbani, who is… Continue

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…

Energy efficiency, the Nerd

The renewable energy business has done a remarkable job at positioning itself in the public psyche as the ‘it girl’ of our era.  Just about everyone – politicians, celebrities, major industries – likes to be seen as pro-renewable.

But if renewable energy is the girl that everyone wants to be photographed near, energy efficiency is her nerdy tag-along little brother.  Ever notice how when politicians say they support…

Defining Quality: The John Tooley Way

Although I was a first-timer at ACI a couple of weeks ago, there were so many more numbers that I found interesting. First off, attendees had 144 sessions to choose from in just 2.5 days, there was at least on person in attendance from all 50 states (and 7 Canadian provinces), there were 101 exhibitors (the largest to date), and ACI celebrated its 25th anniversary. For all of this, I have one word: Wow!

 

And as attendees heard in the opening general session, all of this… Continue

Beware of Power Factor Correction products!

This post was originally posted here.

 

 

Product developers know that as energy costs rise, consumer's budgets get tightened, and people start to care more about their environment (the trifecta of sustainable drivers), those consumers are going to want products that help them save energy.  But do all these products live up to their…
