Custom homes. Smart architecture. Real comfort.
Building a custom home is your chance to get cooling right from the start. No retrofits. No regrets. Rosten Home Insight brings you architect-grade passive cooling strategies: solar orientation, overhang sizing, thermal mass placement, cross-ventilation paths, and night flushing. We also cover low-energy backups for the hottest days: DC ceiling fans, single-zone mini-splits, and personal evaporative coolers for home offices or bedrooms.
4 Architectural Moves for a Cool Home
1. Orient living spaces east-west
Put bedrooms and home offices on east and north sides. Put garages and storage on the west. Morning sun is gentle. Afternoon sun is brutal — keep it off your main rooms.
2. Size overhangs for your latitude
At 40 degrees north, a two-foot overhang blocks high summer sun but lets in low winter sun. At 34 degrees north, go deeper — three feet or more. Free cooling and heating.
3. Add thermal mass where sun hits
Tile, brick, or concrete floors on sun-exposed surfaces absorb daytime heat and release it at night when you open windows.
4. Plan for room-level active cooling
Not every room needs ducted AC. For a detached home office or finished attic: design for a mini-split, a quiet fan, or a personal evaporative cooler within a few feet of where people sit.
