Sketch morning and afternoon sun angles, then place work zones where daylight is generous but controlled. Combine high windows, light shelves, and matte finishes to bounce luminance deeper indoors. A neighbor added a clerestory and cut daytime lighting use by half without sacrificing privacy.
Pair operable windows on opposite walls, size inlets and outlets proportionally, and keep interior doors aligned to encourage consistent airflow. Ceiling fans on efficient DC motors assist gently. In a humid coastal retrofit, this approach reduced evening AC runtime by nearly forty percent during shoulder seasons.
Borrow space from circulation to grow storage where clutter accumulates, letting smaller rooms live larger. Built‑ins along unused edges eliminate duplicate furniture, lowering material demand. One family removed a hallway, added pantry niches, and found their kitchen needed fewer lights because surfaces reflected shared daylight.
