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
Rate design is the method by which an energy utility calculates charges for the energy you use and for the infrastructure used to deliver that energy to your home. This post explains how these charges are calculated.
How Are Energy Rates…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
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
Note to Homeowners: This article is primarily aimed at the Home Performance industry. I strive for radical transparency, so I put this in the public sphere for you to read as well.
Energy efficiency rebate programs from gas and electric utilities have become pretty common nationwide. They give rebates for replacing your furnace or adding insulation to your home. While these programs seem like a good idea, they can actually…Continue
In addition to saving energy, net-zero technologies offer a plethora of health, safety, and environmental benefits; but achieving zero energy can be prohibitively expensive. In this interview, Lucas Alm and Dan Handeen…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
What makes a Green Home green? Is it the bamboo floors? Maybe it’s the low-e windows or the extra insulation in the walls? What about a high efficiency heating and cooling system? Or maybe it's a plaque by your front door that says, “I'm Green!”?
How about all of the above and then…Continue
