Insulating a Slab-On-Grade in Hotlanta

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…

Using Stone and Wax for a Perfect Residential Building Enclosure

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…

Mini-Split Heat Pumps are Quirky, Especially their Capacity

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…

What do Ducted Mini-Splits Look Like?

Designing A Perfect Residential Wall - Atlanta, Georgia

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 …

Why Don't Architects and Interior Designers Care About HVAC Systems?

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…

No More "Damn Architects!" - The Case for Integrated Design

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…
