Fitness wearables inspire people to change; to exercise more in order to meet their daily goals. These sophisticated gadgets gather previously untapped data about our everyday lives to give us a better understanding of ourselves – otherwise known as the “quantified self.”
Like fitness wearables, exposing how we’re using energy can unlock our collective potential to reduce our electricity bills and our…Continue

A curious situation has recently arisen in electricity grids around the world: The wholesale price of electricity has occasionally gone negative. This means that the market will pay customers to use electricity. The grid in Texas experienced negative prices last September. Soon afterward, a Texan retail electricity provider—not to be confused with a utility—began offering residential…Continue

I have hour meters on maybe 20 systems now. I like to see the run time when it's "4" degrees in Kansas City. 99% rate in KC is +4' degrees. My goal at 4' is 100% run time. I have a super sealed home 2,100 square feet with a 2 ton ground type heat pump R-30 walls, R-60 attic, R-8 windows & doors with 98% run time @ "+ 4' ". When the strip heat turned on, it smelled up the home with the dirt off the 5 KW strip, heat…Continue

When we built our new home 50 miles from Austin on 21+ acres we made the decision to have all of our indoor water come from harvested rainwater and to make our flower gardens bigger than they were at our first country…Continue

First of all I am 59yr old retired Federal employee. I took HVAC in a trade school 30 years ago. While working a full time job, HVAC was basically side work for me. After a couple years of residential installs and service work, I transferred into the building maintenance dept. HVAC was 75-80% of my job. We went to several onsite schools for a couple days here and there for the newest HCAV stuff. Keep in mind this is all commercial units we are working on in Federally…Continue
Starting February 8, 2016, the Michigan Energy Code will adopt the 2015 edition of the International Energy Conservation Code (2015 IECC) with "amendments, deletions, and additions deemed necessary for use in Michigan." The state will be skipping the 2012 IECC, thereby increasing the energy efficiency requirements of its homes by 10-12%.
What is the 2015 IECC?
State building codes exist to provide a standard set of guidelines for all builders,…Continue
A fan is a mechanical device, which produces a stream or flow of air/gas. The fans are used both at residential and commercial spaces serving different purposes. These are often used to move air or gases via ventilating systems. In industries, these are used to force air inside the hot steam boilers and help to reduce the temperature of machines and other equipments. Fans function similar to the compressors, which is relatively at low pressures. These are basically divided as axial and…Continue

Insulating a Slab-On-Grade in Hotlanta
Why in the world are we insulating a slab-on-grade in Hotlanta?
Reason #1: Atlanta is not, I repeat, NOT a cooling dominated climate. Wait...What?!?!?
Yes, it gets plenty hot here in the Summer, but it also gets downright cold. Which is why it's one of the more difficult climates to design and build in. We get both extremes.
I'm not saying we know what cold is, like all y'all do up yonder in them…Continue
Many of us have been working for decades to push the energy codes toward higher performance. We've had some good success along the way, as state after state adopt more stringent codes. Unfortunately, in many regions we have a long, long way to go. Even in those places where the most stringent codes are in place, execution and enforcement are often weak. And, as for going…Continue
A Perfect Residential Building Enclosure
Buildings fail. It's a harsh reality, but they do, and for many different reasons. Two pretty common ways are by falling down, and by making the people in them sick. There is a long list of other reasons, but this post is focused on these two.
I am going to…Continue

You would be professionally remiss if you did not read “Attics and Crawl Spaces” in this issue. The article by Terry Nordbye is a valuable reminder that home performance problems too often begin in the places that we least want to work on or inspect. Mold, dry rot, and despicable smells emanating…Continue
