Sustainable design is mostly physics and durability: use less energy, waste less material, and build things that last.

Where professionals help

Tradeoff analysis — e.g., glass vs energy, open plans vs acoustics, electrification vs panel capacity.

Certifications

Optional frameworks (Passive House, LEED, local green codes) add structure and sometimes cost. Use them when they match goals.

Budget honesty

Some green features pay back; some are values choices. Separate them in the brief.
