$ OVERHEATED. THE OPERATOR OF THE BUILDING WOULD IN FACT NEED TO
$ TUNE THE SUPPLY AIR TEMPERATURE SETPOINT TO ELIMINATE THE
$ PROBLEM.
$ THE SUPPLY AIR TEMPERATURE IS SET AT 100F FOR ONE HOUR ON WINTER

$ FULL FOR THOSE HOURS. THE SUPPLY AIR TEMPERATURE IS 60F AT ALL

$ HAVC SYSTEM DESCRIPTION
$ DESIGN TEMPS COOLING 76F HEATING 70F.
$ SYSTEM TYPE A SINGLE VARIABLE AIR VOLUME SYSTEM SERVES THE ENTIRE BUILDING.
$ THE SYSTEM HAS A DRY BULB CONTROLLED ECONOMIZER WITH A LIMIT
$ TEMPERATURE OF 68F AND THE FANS HAVE A SPEED CONTROLLER. THE VAV
$ BOXES HAVE A MINIMUM STOP OF 20%. BASEBOARD RADIATION IS NOT
$ CONTROLLED BY SPACE THERMOSTATS BUT BY A RESET CONTROL THAT
$ IS A FUNCTION OF OA TEMP. THEREFORE THE BASEBOARD IS ACTIVE
$ AT NIGHT BUT THE FAN SYSTEM CAN CYCLE ON IF NECESSARY TO HOLD
$ THE NIGHT LOW LIMIT SETTING OF 55F. THE FANS CAN START AS
$ EARLY AS 5AM BUT ARE DELAYED AS LONG AS POSSIBLE (I.E., OPTIMUM
$ START). FANS ARE OFF AFTER 6PM AND ON WEEKENDS AND HOLIDAYS.
$ THERE ARE REHEAT COILS IN THE VAV BOXES THAT ARE CONTROLLED BY
$ SPACE THERMOSTATS SINCE THE BASEBOARD RADIATION IS SIZED ONLY
$ FOR GLASS CONDUCTION. A HUMIDISTAT CONTROLS THE
$ RETURN AIR HUMIDITY AT 25% RH BY ADDING STEAM TO THE AIR. TO
$ PREVENT ADDING MOISTURE TO LARGE QUANITIES OF OUTSIDE AIR, WHICH
$ IS VERY COSTLY, THE ECONOMIZER DAMPERS ARE CLOSED BELOW OUTSIDE
$ AIR TEMPERATURES OF 45F. THE FREE COOLING CYCLE ON THE CHILLERS
$ PROVIDES NECESSARY MECHANICAL COOLING, SINCE OUTSIDE AIR COOLING
$ IS LOCKED OUT.

$ BUILDING DESCRIPTION
$ THIS EXAMPLE HAS THREE SPECIAL FEATURES:
$ 1 IT USES CUSTOM WEIGHTING FACTORS FOR THE EXTERIOR ZONES,
$ WHICH GIVES A BETTER SIMULATION
$ OF BUILDING MASS AND HVAC SYSTEM PERFORMANCE.
$ THE INTERIOR ZONES ARE INPUT
$ USING STANDARD ASHRAE WEIGHTING FACTORS WITH
$ A FLOOR WEIGHT OF 150LB/SQFT TO REPRESENT THE MASS OF ELEVATOR
$ SHAFT WALLS, WHICH ARE ASSUMED TO BE HEAVY REINFORCED
$ CONSTRUCTION FOR WIND BRACING.
$
$ 2 IT DEMONSTRATES DAYLIGHTING AND ASSOCIATED ELECTRIC LIGHTING
$ CONTROLS. EACH 25 FT WIDE BAY ON
$ ALL FOUR EXPOSURES IS TREATED AS A SEPARATE ZONE.
$ THERE ARE 8 BAYS PER FLOOR ON THE EAST AND WEST EXPOSURES
$ AND 4 BAYS PER FLOOR ON THE NORTH AND SOUTH.
$
$ 3 IT DEMONSTRATES HOW DOE-2 INPUT CAN BE SHORTENED BY
$ OMITTING U-NAMES FOR EVERY WALL AND FLOOR SURFACE. THIS
$ MAKES THE VERIFICATION REPORTS LESS READABLE AS MOST SURFACES
$ ARE NOT IDENTIFIED.
$ IN ADDITION, AS ANOTHER WAY OF SHORTENING THE INPUT,
$ ABBREVIATIONS ARE USED EXTENSIVELY,
$ BUT THE FIRST INPUT ENTRY IS WRITTEN USING THE FULL KEYWORD
$ FOR CLARIFICATION. EQUAL SIGNS ARE ALSO OMITTED IN MOST
$ CASES.
$ NOTE THAT THE FOLLOWING DESCRIPTION IS IDENTICAL TO
$ "31-STORY OFFICE BLDG - LOAD1" EXCEPT THAT:
$ (1) CEILING PLENUMS HAVE BEEN ADDED;
$ (2) DAYLIGHTING IS SPECIFIED; AND
$ (3) FOR THE DAYLIGHTING CALCULATION, THE PERIMETER ZONES HAVE BEEN
$ DIVIDED INTO INDIVIDUAL ROOMS, SO THAT RZ2, RZ4, TZ2, AND TZ4
$ NOW HAVE MULTIPLIER=8 AND RZ3,RZ5,TZ3, AND TZ5 HAVE MULTIPLIER=4
$ (AS BEFORE, THE TZ ZONES ALSO HAVE FLOOR-MULTIPLIER=30, SO THAT

$ ENERGY CHARGE DESCRIPTION
$ THIS IS A SIMPLE UNIFORM RATE FOR BOTH ENERGY AND DEMAND IN WHICH THE
$ WINTER AND SUMMER CHARGES ARE DIFFERENT. THE
$ DEMAND CHARGE FOR SUMMER CARRIES FOR THE WHOLE YEAR AT 15 DOLLARS/KW
$ WITH A 100% RATCHET.
$ A 10 DOLLAR/KW CHARGE WITH A 85% RATCHET IS LIMITED TO THE WINTER SEASON.
$ THE METHOD OF CALCULATING THE SUMMER RATCHET IS BY SEARCHING FOR THE HIGHEST
$ MONTH, WHEREAS THE WINTER IS THE RUNNING AVERAGE OF 2 CONSECUTIVE MONTHS.
