Hot water distribution efficiency is now included in HERS ratings, under an amendment to ANSI/RESNET Standard 301-2014. This is a Good Thing. To date, all of our efforts to represent, and then…Continue
The old expression when something is supposed to be simple is to say that, “This is not rocket science!” as though rocket science was the most complicated thing we can think of. I will admit that some of the things rocket scientists have done are pretty amazing. I don’t have a clue how you land a probe on an asteroid moving at thousands of miles an hour somewhere out there in space. Or manipulate a vehicle on the surface of a planet and send back, “Wish you were here!” snapshots - in…Continue
In 2014 there were 146,860 homes in the United States that were energy rated by certified RESNET HERS Raters and issued a HERS Index Score. According to the data from the U.S. Census Bureau this represents over 33.8% of all new homes sold in the nation. The average HERS Index Score of the homes rated in 2014 was 63.
The five leading states in terms of homes receiving a HERS Index were:

The Internet of Things has already improved my everyday life. Devices that communicate with each other deliver new services and features that I appreciate. However, as the Internet of Things expands from a few linked devices to a pervasive network, I fear that aggravation will soon replace appreciation. Are we moving toward the Internet of Annoying Things?
We become aware of the Internet of…Continue

Building owners can save money by investing in energy efficiency improvements. But if they can’t afford the upfront costs of the upgrades, they continue to pay higher energy bills and are even less able to pay for energy efficiency improvements down the road.
On-bill financing (OBF) is one tool to help owners break out of this cycle. It provides an opportunity to invest in energy…Continue
I wanted to encourage all you deep energy/ZNE enthusiasts to hie thee to the Net Zero North American Leadership Summit in Boston, March 3-5. The program is a standout, ranging from solar pioneer Steven Strong to Senator Jaime Eldridge to energy guru Marc Rosenbaum, and countless other rock stars. Here's the program. Check it out, register now! Wide-ranging discussions will be had (I first typed "ranting" --…Continue
Imagine this: you go out to your local entertainment big-box store and purchase the top of the line “HUMONGOUS” television. When you get home, you don’t think anything about it and just go ahead plugging it directly into the wall socket, right? What’s that you say, ludicrous? Of course, we would only plug that piece of beautiful technology into a UL rated surge protector!
So, I gave it away in the first paragraph: a UL rated surge protector. But, don’t…
It’s no secret that finances are often a barrier to home performance upgrades for homeowners. This is precisely why programs like the PowerSaver loan program are helpful as they work with contractors and equipment installers interested in offering energy efficient financing at the point of sale.
So what is the PowerSaver loan?
There are three PowerSaver…Continue
One challenge seems to be at the forefront of a lot of the discussions I'm having with colleagues and associates these last few weeks is sales. Closing sales. Making the sale. Getting some traction...getting any movement at all...

We had some serious problems with rotting in buildings that were constructed in the period 1980 and 2000s. ‘Leaky Condo Crisis’ reached fever pitch in Vancouver, BC and surrounding region (excellent Wikipedia entry details the problems, the situation and the fallout here.
In a nutshell, SoCal dry-hot climate details (no rainscreen, no overhangs)…Continue

UPDATED: Break Even COP’s for MA
How do you know if you should install a ductless mini-split, or upgrade your air-conditioner to a heat-pump and create a dual-source application during replacement this Winter? I have been asked this countless times over the past week! I personally always prefer the option of multiple fuel sources, particularly since energy prices have been all over the place during the last decade. Fortunately, using averaged…Continue

In reviewing the content of Home Energy's January/February issue, I was struck by how rapidly the energy-saving business is changing. In the issue, we cover the come-from-nowhere explosion in LEDs. Another article about energy-efficient homes in Germany describes the rapid shift to near zero energy homes. That article also reminds us why it is getting risky to ignore activities on what used to be the…Continue
Clean Energy Works Oregon (CEWO) is the largest nonprofit home performance provider in Oregon, according to Derek Smith, CEO of CEWO. I spoke with Derek earlier this year about his work in the Pacific NorthWest region.Continue
In November 2012 I replaced 80% of my home's interior lighting with LEDs (35 bulbs total) - see my LED Lighting, 6-month update blog post.
Today, 12December2014 is my 24 month update:
My 'Life-Test' bulbs (a pair of lights above my fireplace) have been 'ON' continuously for 25 months (760 days x 24hrs/day) - 18,240…Continue

In September 2013, we posted a blog called Las Vegas: Bright Lights, Green City?questioning how energy efficient a place nicknamed “Sin City” could actually be. That post focused primarily on the growth of LEED-certified buildings in the city. Here we are now, and I see that the 2015 New American Home will debut at the International Builders Show in – where else – Las Vegas…actually, Henderson, which is…Continue
