Editorial: Reflections on ACI

An industry's health is sometimes measured by the enthusiasm of its trade shows. Arguably, ACI is not a trade show, but it certainly is a bellwether for the home performance industry. And it rocked. By all measures, ACI was larger, broader, and more exciting than past conferences.

ACI continues to be a magnet for audiences ranging from contractors just starting out and receiving blower door training to engineers and building scientists. In this way, it serves as the premier…

Energy Out West

The Energy Out West conference is held every other year and began in 1996 when a group of people doing weatherization work in the Northwest thought they could help each other do it better. The current president of Energy Out West (EOW) is Mimi Burbage, who should be familiar to readers of Home Energy and anyone in weatherization. Mimi brings that independent, Alaska, straight talk style to whatever she does, from heading the Alaska Housing Finance Corporation to her work for EOW.…

Non-Condensables? Are you sure?

  Non-condensables in a residential split air-conditioner can be, for most technicians, a pandora's box to diagnose.  Fortunately, there is a simple process that can identify this condition without spending hours and hundreds of dollars in virgin refrigerant.  I think we all are aware that R-22 has hit an all time high, so getting this right is more important than ever - if you want to retain your customer.

  There are several ways air and/or water vapor can enter a sealed system. …

ACI National Home Performance Conference: Setting the Pace for Change

This year ACI held its largest ever national home performance conference in Baltimore, Md.  It was the largest in the number of workshop sessions: over 195 sessions, in 25 thematic tracks; with the largest number of exhibitors (115) and sponsors (48).  

The three themes stood out: a) keep it simple (from the homeowners perspective); b) there is no silver bullet; and c) HVAC is jumping into home performance, maybe not head first, but at least with both feet in a measured…

New England; HRV or ERV?

I remember installing some early version residential Energy Recovery Ventilators (ERV) and discovering a potential freezing issue.  Also, if I used only a Heat Recovery Ventilator (HRV) than I would be drying the air during the Winter, and adding significant latent load in the summer.  So, which one do I choose?  The homes are tight enough these days to require mechanical ventilation, and I would much rather a balanced ventilation system that I can control.…

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…

5 Stats Your Next Client Must Hear

Energy auditors and retrofitters know that it’s hard to sell the benefits of energy efficiency to homeowners. But the truth is that energy efficient upgrades save homeowners money, help sell homes quicker, and yield a higher profit when on the real estate market.

Because it’s not always easy to explain industry ratings and scores to homeowners, auditors need to be armed with statistics to help convey their message. I’ve compiled six statistics that show the importance of energy…

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…

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…

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…

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…

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…

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…
