In a November 2013 post, we mentioned that the RESNET Combustion Safety Deadline was fast approaching. At that point in time, RESNET had already announced that all existing HERS Raters needed to complete the new combustion safety training and testing by 2015 in order to maintain their certification. Here we are in the new year, and some may be wondering - Where do I stand? Am I still active? What do…Continue

As an outspoken supporter of the necessity to move toward green and reusable energy I often find myself debating individuals critical of such technologies, particularly solar energy. The level of misinformation and on occasion downright ignorance leveled toward the solar community is baffling to say the least. With so much misinformation running rampant amongst the solar skeptics amongst the world I found it prudent to clear up some of the most common distorted oppositions to an industry the…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
Awhile back, Joe St. Pierre over at Aeroseal Solutions got a call from Dale McClelland, a licensed energy auditor he had met at a recent Chicago-area tradeshow. In his…Continue

I left batteries in the DG700 for 2 years, 2 of them 6 corroded. Manufacturer said that the meter has to be recalibrated. I asked why? Because there is a drift of up to 1% caused by pressure sensor. The question is how significant is this amount. Say we have Blower Door air flow 1650 CFM. So 1% = 16.5 CFM or readout will be between 1666 and 1644. Is the difference practically significant?
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

Most people don't truly consider money spent on their home a real investment unless they are planning on flipping or selling the home quickly. Upgrades to energy efficiency can be a great way to improve the comfort of your home while also saving a decent amount of money every month on your utility bills. Variable speed pool pumps, insulation upgrades, sealing your leaky ductwork can all provide a strong ROI that is virtually guaranteed. Not something that you would be able to match…Continue

“I’d put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that.” - Thomas Alva Edison.
We’ve all learnt about the importance of renewable energy, especially solar energy, back in school days. However, it was only when we discovered that levels of our non-renewable energy sources are going down that we realized the importance of utilizing the benefits of renewable sources. That…
A new study from the National Institute of Standards and Technology (NIST) revealed that poor installation of air conditioning and heat pump units often leads to unsatisfactory energy performance. This research took three years to compile, with the help of surveys, field evidence, and various measurements for modeling. The most common installation errors included leaky ducts, improper refrigerant charge, oversizing of systems, and restricted…Continue
As many know, by the end of this year all HERS Raters & Field Inspectors (RFI’s) in good standing must complete a three prong CAZ training & testing requirement (assuming it was not part of their original training). While one can debate should they or shouldn’t they have done this, the die has been cast and the mandate has been made. In case this is news to you,…Continue

An important deadline is looming for existing HERS Raters. By January 1, 2015, all existing Raters must have passed both the combustion safety written and simulation exams to maintain their certification. If existing Raters do not successfully complete these tasks, they will lose their certification and will not be able to perform home energy ratings as part of their business. This also applies to existing RESNET Rating Field Inspectors.
If you earned your HERS certification prior to…Continue
