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…

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. …

President Obama calls for a strategy "that relies less on foreign oil and more on American-made energy"

A strong commitment to the development of alternative energy has been made by President Barack Obama. In a recent radio address, the President called for a strategy "that relies less on foreign oil and more on American-made energy". These renewable energy sources, which include solar and wind power, will not only help wean the U.S. from fossil fuels, but create thousands of new American jobs. Solar training of these workers will be an important part in expanding alternative energy…

How To Reduce Energy at Home

9 Steps to a More Energy Efficient Home and Lower Power Bills



How to reduce energy at home has gradually become a household desire as a result of high definition T.V.'s and homes the size of a castle. Throw in a struggling economy and the melt down of a nuclear plant and becoming more energy efficient seems like a great idea.

Our power bills rise as a result of increasing power costs and the need for more and more power to operate are power hungry homes and…

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…

The Rise of Electric Vehicles in the United States

In 2009 stimulus money was granted for over $2 billion dollars by the government to set up training courses for professional mechanics and individual persons in regards to knowledge and repair training of the new electric vehicles. By 2015 the government of the United States would like to see an increase in the rate of electric vehicles on the road upwards to at least one million vehicles. Development of electric vehicles may answer some of this country's problems but it certainly will not…

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…

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…
