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…

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…

A Green Home - It's Just Good Design

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…
