Energy Efficiency Ratio (EER)

Energy Efficiency Ratio, or EER, is a way to exhibit how well an air-conditioner is operating based on the power being used.  Most homeowners are of course familiar with SEER, the ratio across an entire season.  Since SEER is tested at a "partial load", the EER is a more realistic number to use when figuring energy savings.  AHRI tests their EER of residential air-conditioners using 400 CFM per ton of airflow at 95F Outdoors / 80F Indoors and 67F Wet Bulb.  This compared to the SEER testing…

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.…

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. …

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…

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…
