Building with Rocks, Rocks! Check out the Drying Potential.
Check this out! This 24" x 48" x 2" thick piece of rigid stone wool insulation was left out overnight (on purpose) on the High Performance Tiny House project site, to see how it handles a deluge of rain, which we knew was coming. One of the many …Continue

This blog post is guest written by former staff member Eric Keeley.
Great enthusiasm for home energy efficiency is often matched with misconceptions. Let’s explore a bit and figure out the difference between what we perceive, believe, and what we know to be true.
Windows: We see through them every day and curse the drafts coming through and around them. We are certain that old windows are the main culprit behind why we spend so much…Continue
Rainwater harvesting is a system which requires a two-step process. The two major events in rainwater harvesting are catchment and storage. The first hurdle is developing an adequate method of collection. Once the rain is collected, a proper and large storage system is required. The complexity and size can vary dramatically. The simplest methods involve the rerouting of gutters into an above ground rain barrel up to a complex system of catchment dishes, filters, pumps, ponds 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
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

As the demands for Green Buildings increase, so does the demand for comprehensive rating systems that define exactly what a Green Building is. While it may seem like having a rating system for Green Buildings would confine Green Building and discourage innovation, this is not the case. Many different Green Building rating systems that are currently in place encourage innovation and builders who incorporate particularly innovative aspects into their Green Building can earn extra points and…Continue

I was called in to perform a last minute duct test for a modular home builder. He was all in a dither to have a duct test and a blower door test done on a Friday so that he could get his Certificate of Occupancy (CO) so the homeowner could move in the following Monday. He said that he’d just found out that he needed these tests. The building inspector asked for them at the last minute!
I was glad to do it partially because it’s good to have builders aware of what is going on…Continue
If your building is not tested by air testing companies uk then air will continue to flow through the leakages and damage your wall, increase your power consumption and you will suffer from allergic diseases.
Air tightness testing can be done after the building construction is completed. It is recommended to hire air testing experts for your…Continue

Indoor air testing and detection of impure particles suspended in the air are definitely a laborious task but in order to keep a building and the rooms of a house safe and pollution-free, there are serious needs of air quality testing. We often tend to ignore the fact that due to air impurities almost more than seven million people die in the world every year due to respiratory ailments caused by moulds, termites, carpet dusts, pesticides and even room…Continue

Sandeep and Carolyn Sood own several apartment buildings in Chicago, but the 55-unit building at 6731 S. Jeffery Boulevard is special. The building is one of the first in the country to receive the new ENERGY STAR® certification for multifamily buildings.
“For us, it’s an important designation. It shows people that want to live here that we care.…Continue
In July 2013, the State Board of Building Regulations and Standards (BBRS) voted to adopt the 2012 International Energy Conservation Code (2012 IECC) and ASHRAE 90.1-2010 with MA amendments as the new baseline energy code. The BBRS allowed for the new regulations to run concurrently with the current energy regulations until July 1, 2014. During that time, either set of energy regulations could be used when applying for…Continue

Liz Vogel replaced the windows and updated the heating system in her small multifamily building in the Logan Square neighborhood of Chicago. But she still noticed that parts of her home were not staying warm in winter. So she set out to solve the mystery of the missing heat. She saw icicles hanging from her roof, and that was a clue that pointed to where heat was escaping. The presence of these “ice dams” meant that Liz was paying to heat her roof and melt the snow instead of heating her…Continue
