Code Conflict Between 2012 IRC and 2012 IECC

It has come to my attention that there may be a building science-based conflict in the language of the 2012 International Residential Code (IRC) and 2012 International Energy Conservation Code (IECC).

The 2012 IECC sets the mandatory blower door tested and certified air infiltration rate at 5 ACH50 in CZ1 & 2 and an even tighter 3 ACH50 in CZ 3 and above. The problem lies in the fact that the new…

Home Performance and HVAC Contractors: Recent Legislative Initiative In Texas

As energy auditors and raters went about their business of testing homes, performing energy audits and HVAC system inspections, they discovered and reported certain “problems” to the homeowners of Texas. For example, they reported that HVAC systems were oversized, or suffering from massive duct leakage! In late 2011, The Texas Department of Licensing and Regulation (TDLR), which oversees the HVAC industry,…

Three WWWs to completing the Appraisal Institute’s Residential Green and Energy Efficient Addendum

The Residential Green and Energy Efficient Addendum is a form used to standardize the reporting of high performance house features from green certifications to incentives offered.  The Addendum can be downloaded in a PDF format from the Appraisal Institute’s Website.  It is seems there is much confusion on who should be completing the Addendum, why they should complete it and what they…

Excellent PBS Energy Program Worth Watching

In case you missed it, PBS has been airing a series "EARTH: The Operators Manual".  The  recent episode which aired last week "Energy Quest USA" is well worth watching...

While many of us discuss methods and marketing for audits and retrofits, I believe it is the community neighbor-to-neighbor programs and activities that engage the homeowner and get results. The show profiles communities making smart energy choices based on economics and the environment. Below is a link to the…

Prior to any real consideration of adopting alternative energy sources like wind or solar, it is paramount to consider a homes energy inefficiencies.  Cost savings are negated, almost immediately, when you attempt to power a home through revolutionary methods and antiquated building materials / practices.

The two subject matters have to be in congruence for the conversation of 'renewable', 'green' (whatever that really means) and 'sustainable' to carry any relative meaning.

Rather than using those traditional methods such as fire to get warm water, you can avail the benefits of advanced heating technology using a quantum heat pump.

Using such an energy-efficient heat pump can ease up your life to a significant extent. With its…

Momentum builds for energy efficiency...but is the wolf at the door?

It says something that Ernest Moniz chose to deliver his first public talk as US energy secretary to an energy efficiency crowd.

His appearance last week at EE Global in Washington, D.C. was a surprise of sorts. And the timing was significant. Moniz had only been confirmed as energy secretary three hours before taking the podium at the Alliance to Save Energy’s annual conference.

Why did he make the stop?

Probably not because of the size of the crowd. About 550 people…

Change is Hard—How Do You Get People to Accept It?

Changing one’s daily routine and making big decisions about money is hard. When a home performance contractor asks a customer to consider an audit, they are asking a lot. Besides the cost of the audit and any retrofit measures the homeowner chooses to pay for, which is probably the biggest challenge, there is also the inconvenience. The audit and retrofit may require the homeowner to take time off from work. Having workers climb in and out of the attic, under the crawlspace, and drill holes…

HOMES Act introduced with Bi-Partisan Sponsorship

We don't see a lot of bi-partisan bills in Congress these days. Here's one focusing on home energy-efficiency from a WV-R and a VT-D, both on the energy committee, the HOMES Act, HR 2128 ( introduced yesterday.  Now, I'm not holding my breathe on passage, but I take it as a good sign that energy-efficiency is part of the…

Less oil, more courage: Energy and Art

Hard to admit, but I'm not all fun-facts all the time. Sometimes I even pay attention to things that aren't energy related. So, rather engineering geek-speak that dominates the energy efficiency professional’s lexicon, today’s post is about “energy art” as a counterbalance to the usual “art of energy” commentary. This is a subject I've been following for many years and it's inspiring to see what artists can do with solar panels, radiators, and flame.
Today, I'm…

The Universe Is Made of Stories

The late poet and political activist Muriel Rukeyser famously said, The Universe is made of stories, not of atoms. It’s not just words that make up stories. A scientific equation is a story, and so is getting up from my seat and stretching—it’s the story of back care for an editor. We can tell a story with the expression on our faces. What does it tell you when a loved one rolls her eyes at you, or blows you a kiss? How do you feel when a stranger winks at you? Flips you the bird? That last…

Preparing to Update the Heat Pump

This is the latest from Foskey Road News, a business blog that is strictly consumer focused.

by Edward Foskey

Based on the life expectancy of the heat pump that came with my house when I bought it, I know that I am already living on borrowed time. I just recently had a minor repair and the semi-annual check-up. My plans are to start preparing to replace it by next spring.

I know…

Selling with Rebates: The Simple Payback

  The easiest way to show a homeowner how their investment in high-efficient equipment will help their wallet is to use the "Simple Payback" Calculation.  This 'tried and true' sales tactic will quickly explain how many years before the additional investment to upgrade is paid off.  Of course, there are many features that a high-efficient system provides, like superior levels of comfort, wether it be climate control or just condenser noise just outside their children's bedroom.  These…
