Energy Fit: Engaging Consumer Experiences That Lead to Better Energy Habits

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.”

Free Electricity

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…

Who among us tracks the accuracy of Manual J?

Who among us tracks the accuracy of Manual J?

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…

Bonus room attic walls heat load

Hi Everyone...

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…

Michigan Energy Auditor Certifications

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%.

Axial flow fans – An Overview

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…

Insulating a Slab-On-Grade in Hotlanta

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…

The Compliance Project

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…

Using Stone and Wax for a Perfect Residential Building Enclosure

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…
