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.
