    !
    ! Each floor is modeled as four perimeter zones and one core zone. The perimeter
    ! zones are all 4.57m (15 ft) deep. Windows are modeled as a horizontal strip of
    ! glazing running the length of each perimeter wall from the middle to the top of
    ! the wall, for a Window-to-Wall Ratio (WWR) of 0.50. The 4 intermediate floors
    ! are modeled as 1 floor with a zone multiplier of 4 applied to each zone. The floors
    ! and ceilings of the zones on the intermediate floor are modeled as adiabatic surfaces.
    !
    ! The building is oriented with its long axis east-west.
    !
    ! Internal loads (peak) are :
    !
    ! Occupancy 36.23 m2/person (390 ft2/person)
    ! Lighting load  12.59 watts/m2 (1.17 watts/ft2)
    ! Equipment load 8.07 watts/m2 (0.75 watt/ft2)
    ! Elevator load 27.75 KW (NOT IMPLEMENTED YET IN THIS FILE)
    ! Hot-water usage 0.889 l/hour/person (0.0039 gal/min/person) (NOT IMPLEMENTED YET IN THIS FILE)
    ! Occupied hours 8 through 18 weekdays, 8 to 13 weekends
    !
    ! System controls are:
    !
    ! Heating 21.1 C (70 F) occupied hours, 12,8 C (55 F) unoccupied hours
    ! Cooling 23.9 C (75 F) occupied hours, 32.2 C (90 F) unoccupied hours
    ! The basement is unconditioned but has a constant heat source of 6766 watts representing
    ! the losses from the plant
    ! Heating and cooling turned on 1 hour early, and turned off 1 hour late
    ! Outside-air 25 m3/hr/person (15 CFM/person)
    ! Economizer with limit temperature at 20 C (68 F) (BUT IS SET TO NO ECONOMIZER IN THIS INPUT)
    !
    ! HVAC:     Standard VAV system with minimum outside air , hot water reheat
    !           coils, central chilled water cooling coil. Central Plant is single
    !           hot water boiler, electric compression chiller with water cooled
    !           condenser. All equipment is autosized.
    !
    !           The supply air temperature setpoint is established by a seasonal reset.
