TOPOS approaches sustainability from the ground up: we start passive—shaping orientation, envelope, and airflow so buildings work hard on their own. We favor low‑carbon, responsibly sourced materials, design for durability and adaptability, and pair high‑performance fabric with efficient systems and PV readiness. Water-wise landscapes, healthy non‑toxic interiors, and daylight are built in, and we verify performance with modeling and post‑occupancy feedback.
