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
In my last four HVAC Design jobs, I've specified ductless mini-split heat pumps. I have four more such jobs underway now.
My recent visit to Savannah for the USGBC's green product expo charged up my historic preservation bug and got me to thinking about how to apply building science to historic buildings.
Most of us that have ever lived in, owned, or even just visited a historic home…Continue

In 1997, I helped my parents design and build their home. Early in the construction process, I had suggested that the house be built 25 feet back from where we originally had it planned, and that the fireplace be moved to the back side of the living room. We had already put the stakes in the ground and were ready to start digging for…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
