January 2023 - Town Homes, Blower Doors, and Why Code Is Just the Minimum
WYSL/ Wise Home Energy Show
Jeff Flaherty opens with a habit he can't shake: driving past town home complexes and reading the snow melt patterns on their roofs. He explains why town homes create unique energy challenges, how HOA rules affect what you can fix, and why a room over a garage with unsheathed exterior walls is one of the most common comfort complaints he gets. From there he walks through how a blower door works in an attached home (you're measuring leakage to the neighbors too, not just to outside), why a tight blower door number still means nothing if the air is leaking into the attic, and why code is just the minimum, not a comfort standard. He also covers a client who had two contractors insulate his home without a blower door and still has uncomfortable rooms, why an oversized furnace acts like blood pressure on your duct system, and why banning gas appliances is not the same thing as improving indoor air quality.
