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

Reducing and managing energy consumption saves money, and at the same time helps in checking climate change and strengthen corporate reputation. The main aim of an energy management system is to maintain optimum energy utilization throughout the organisation. This helps in lowering energy costs and mitigating the effects on the environment. In order to reduce power consumption, you can hire companies that provide energy management…Continue
The air foil fans are created and designed for moving the high volumes of clean air at low to medium kind of static temperature. Since 1975, it has been used for its promising performance and low energy consumption. The airfoil fan blades are inclined backwards and they are created by using the same aerodynamic principals which are used to make an aircraft. The airfoil fans are among the competent centrifugal fans and put forward multiple utilities. These fan blades are also…Continue

The idea of business transparency might seem antithetical to success and may frighten some companies. But collaborative efforts across businesses and sectors have shown that the triple-bottom-line benefits of transparency far outweigh the perceived risks. In fact, as more consumers demand proof that the products they buy fulfill the promise of the label, transparency is becoming a key differentiator that sets…Continue

Sparky Doubled the Air Leakage in this Home
This is the home.
This is the hole that Sparky (electrician) "innocently" made to feed a wire to the light on the front porch of the High Performance Bungalow. I discovered it a day or two after our home performance diagnostics team, Carl Seville and Abe Kruger, of SK…Continue
Last year I moved into a house that needed some work. So far I’ve replaced the foundation, installed seismic upgrades, added central heat, repainted, and much more. (Anybody know a good fireplace guy?)
Along the way, I’ve been slowly upgrading to smart home technology. I ripped out my old, broken doorbell and added Ring, which detects when people are at my door and sends a video notification to my phone.…Continue
