Unitary System and VAV using HVACTemplate Inputs[LINK]
Rectangular single story building with 5 occupied zones and a ceiling plenum
Packaged DX cooling with gas heat serving one zone
VAV with reheat and return plenum serving the other 4 zones
All equipment autosized using summer and winter design days
Details of the Exercise[LINK]
Single floor rectangular building 30.5 m (100 ft) by 15.2 m (50 ft) by 3m (10 ft) high.
Building is oriented with the long axis running east-west.
Floor Area 463.6 m2 (5000 ft2).
5 occupied zones - 4 exterior, 1 interior, zone height 2.4 m (8 ft). Exterior zone depth is 3.7 m (12 ft).
1 plenum zone 0.6 m (2 ft) high.
Windows on all 4 facades
South and north facades have glass doors.
South facing glass is shaded by overhangs.
Walls are wood shingle over plywood, insulation, and gypsum board.
Roof is gravel built up roof with mineral board insulation and plywood sheathing.
Floor slab is 0.1 m (4 in) heavy concrete.
Windows and glass doors are double pane Low-e clear glass with argon gap.
Window to wall ratio is approximately 0.3.
Lighting is 16 W/m2 (1.5 W/ft2).
Office electric equipment is 10.8 W/m2 (1.0 W/ft2).
1 occupant per 9.3 m2 (100 ft2) of floor area.
Infiltration is 0.25 air changes per hour (always on, proportional to wind speed).
