In August of 2016, we posted a video describing the design and construction of the foundation and floor framing of our High Performance Tiny…Continue
Raising the BARrier in North Carolina Mountain Home, Making it Super Air Tight!
The AIR Barrier at the ceiling plane, that is....
At LG Squared, we have experimented with many ways to design and build a roof assembly for a home. Without question, we have found the ventilated attic to be THE most effective.…Continue
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

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
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
High Performance Tiny House, an Experiment
In graduate school, I chose to focus on the work of Finnish architect, Alvar Aalto, during a study abroad trip. One of the buildings that stood out, was his …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
Building Science is Worthless...
Thousands of hours went in this construction detail. When we factor all the time spent by building science engineers, from all over the world,…Continue
Mini-Split Heat Pumps are Quirky and Still Effective
The name "mini-splits" generally refers to heat pump systems with one outdoor unit and one or several smaller capacity air handlers. The efficiency of their operation comes via the inverter compressor and variable refrigerant…Continue
The most recognizable and commonly used mini-split system is the wall-mounted ductless system. They’re seen all over the world and are starting to become noticed and used here in North America, particularly in homes with small heating and…Continue
Before drywall was installed, I tested the infiltration (air leakage) at the Proud Green Home (PGH) at Serenbe,…Continue
Atlanta, Georgia has a reputation for getting pretty darn hot, but it can also get pretty dang cold (No snickering from you Northerners, please!). Believe it or not, Atlantans use more energy to heat their homes than they do to cool them. The design temperature set by …Continue

GUILTY! Once upon a time, I would have scoffed at mechanical engineers and contractors if they'd ask me, as the design architect, for a bigger room to put the HVAC (heating and air conditioning) equipment in.
"Are you crazy? And give up valuable storage space???"
They might have also ask me for dropped soffits and vertical chases to run the ductwork through. To which I would reply:
"What?!?! That's not consistent with my innovative and beautiful design! The…Continue

We’re just a few weeks away from a computer generated, self-guided interactive virtual tour of the Serenbe Residence near Atlanta, Georgia (Climate Zone 3a). We’re using REVIT software to generate the 3D model, then …Continue
