Net Zero hotel reno, of a classic brutalist building designed by Marcel Breuer

Kone elevators use the gravity of cars descending to generate power like automotive regen, also energy storage with weights csan be utilised during peak power periods. All lighting for a 200 room hotel only draws 5000W, since they use low voltage DC power direct from the solar panels or battery, sent to each room on cat 6 power over ethernet! no power wasted with a transformer in each bulb! nice power roll down blinds controlled from bedside. very nicely done dining area, all cooking is done on induction cooking ranges.
