Opaque heat rate per surface = (gross − glazing) × U. Slab-on-grade floor uses F-factor × perimeter. Roof slope/azimuth from above; walls assume vertical (90°).

Setpoints & schedule

Internal gains (defaults from building use; override as needed)

Outdoor air

System selection

Delivered energy = hourly load ÷ COP (heating fuel applied to heating, electricity to cooling/lights/plug). EUI in kBtu/ft²·yr.

Passive cooling & ventilation

Night-flush thermal mass & passive solar

Passive-solar savings use the Balcomb load-collector-ratio (LCR) method; night-flush uses a lumped thermal-mass charge/discharge model on the design week.
