The “Passive House:” Finally a Reality

In years past, the idea of the “passive house” was only a dream. In concept form, the passive house was one that minimized energy losses and operated at maximum energy efficiency. The result would be a home with little to no monthly energy expenses and a fraction of the environmental impact of most homes. Amazingly, the passive house is no longer just a dream; in fact, it’s become a reality. Several companies are able to build passive homes for everyday consumers, creating a huge shift in…

Philips L Prize LED bulb not worth it

The following blog appeared on Mapawatt for the Philips L prize LED bulb cost.   What are your thoughts on the price of this bulb?  Would you recommend it to your customers when there are lower cost LEDs available?

Home Energy Audit 111 Years Old

by Don Ames,   www.detectenergy.com



I gathered up my auditing equipment and headed off to a neighboring community to perform a home energy audit that was constructed in 1901. Before I head out of the office and leave the comfort of my desk computer, I look up the home through County Records to determine about what year the home was constructed, about how big the home is, and if records show any remodel years.

When records indicate…

Caution: Heads May Explode

While listening to Peter Troast of Energy Circle and Allison Bailes of Energy Vanguard speak in front of a room about social media and Internet marketing for the home performance industry, it's easy for your head to feel like it may explode. In the best possible way, of course.

I was lucky enough to get this feeling last week as the duo tag-teamed a presentation…

Big Blue Goes Green - How 203Ks May Be the Future of Green Mortgages

When Sarah Coleman and Carl Sack first saw “Big Blue,” they knew they were home.  The massive house, so named because all the rooms were painted shades of the color, was built in the 1920s on two and a half lots in the Corey-Merrill neighborhood of inner-city Denver.  

 

But their…

Utility Green Button

Below is the post that originally was put up on Mapawatt on the Utility Green Button.  As the Green Button is adopted by more and more utilities, I believe Home Energy Pros should make sure to inform every customer of its existence and how it can help homeowners better manage utility bills.

The idea for the utility Green Button was first put forth by U.S. CTO Aneesh…

Desert Year: Why Is It So Hard to Care?

By Skip Laitner

Guest blogger, Energy Efficiency Markets

 

Why is it so hard to care about snakes? Or the desert? The climate? And especially the environment more generally?

 

This time the snake was real.  Right there on the side of the road.  Some evenings ago, however, in the waning hours of twilight, it turned out to be just a short length of black rubber hose that was also laying…

NOx NOx "Who's There?"

 

 

"Ellie." "Ellie who?"  "The Elephant in the living room."

 

The elephant in our room is NOx, and elephants eat a lot.  Then they poop.  A lot. We need to watch where we step. 

 

As technicians following the BPI Standards, we test for CO in the flue as well as in the ambient air as part of any audit where there are combustion appliances.  Imagine my surprise when my new…

Energy Audit And Energy Saving Measures For A Big Home

The Energy Audit is Complete: The Homeowner Chooses These Energy Saving Improvements

by Don Ames,   www.detectenergy.com

Now that the 5 year old has put down the foam dart gun and stopped crawling in and out of the blower door, it's time to make some energy saving recommendations to the homeowner. After completing an energy audit of the home, it is usually fairly easy to start the conversation with the owners on what they should…

All sustainability is local

“All politics is local.” This quote from the late US Congressman Tip O’Neill continues to frame political strategies today. It turns out his premise also applies to environmentalism. All sustainability is local, as a Massachusetts software company reveals in a new application that takes on the complicated task of quantifying the green efforts of corporations.

 

Massachusetts-based Energy Points has devised a…

When in doubt, Incentivize!

These are the latest ideas and bills in congress, which may or may not actually happen.

First up are new tax credits for homeowners investing in energy efficiency upgrades. The Cut Energy Bills at Home Act.

It's based on annual predicted energy cost savings from heating, cooling, hot water and “permanent lighting” in a primary residence. For a minimum credit of $2,000, homes would need to reduce energy costs by 20 percent. Incremental credits are…

The five disadvantages of solar power


It's intermittent. Solar energy is only available when the sun is shining.

It's low efficiency. It requires large areas of land.

It's not completely free of environmental impact. Ultrapure polysilicon is now scarce.


It's high cost.


You must climb your roof to wash it off. Just ask Ed Begley, Jr.!

Three Steps to Get You Started on Do-it-Yourself Smart Home Automation.

Three Devices That Will Get You Closer to Saving Energy Through Smart Home Automation

by Don Ames,   www.detectenergy.com

I have been enjoying the advertisement on the radio that goes something like this, "If your home was built in the 1950's, why would you expect it to perform better than a T.V. built in the 1950's?"

The point is well taken if you are interested in energy conservation. Homes built in the 1950's do not perform…

Trillion dollar answer to Bachmann's light bulb question

US Congresswoman Michele Bachmann often asks why government should tell us which kind of light bulb to choose. Turns out it’s a question with a trillion dollar answer.

 

We will save $1.1 trillion through 2035 because of existing energy efficiency mandates for light bulbs and appliances, according to a report issued this week by the American Council for an Energy-Efficient…

What leading edge developments should I be focusing on?

You woke up this morning full of vim and vigor, ready to tackle the world of home energy efficiency. Of course, your first dreamy thoughts were: is this major solar flare going to knockout electricity in the midwest power grid, and then, if Fermilab has found proof of the Higgs Boson, will I be able to fully explain the phenomena of convection and chimney effect to people? After your morning coffee, the reality check sets…
