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.
