2 Main Points eQuest is a tool from the Department of Energy. It takes the difficult interface of the more common and helpful DOE-2 and simplifies it.The learning curve with eQuest is much smaller than with the DOE-2 program.eQuest is able to model a multilevel building and all the different loads.
3 Energy ConservationeQuest has a function where Energy Efficiency Measures* can be created and manipulated to see the resulting changes to a model.eQuest also has a life cycle cost analysis tool for each EEM applied to the model.* EEM is another name for ECM, or Energy Conservation Measure
4 ESCO AnalysiseQuest also has the opportunity to input several different utility bill rates and structures to find the annual cost difference for changing ESCOs.Utility rates can be complicated, and eQuest is equipped to handle the most complex billing structures.
6 Building Creation Wizard The opening Design Development Wizard has several options:Project/Site/UtilityEdit Building ShellEdit Air-Side SystemHW Plant Equipment
7 Project/Site/Utility The first things that eQuest requests from the user is:Building address,Typical time table, andUtility rate structure.
8 Project/Site/Utility The first things that eQuest requests from the user is:Building address,Typical time table, andUtility rate structure.
9 Utility Charges (both Gas and Electric) Utility bills can be complex with a multitude of charges. eQuest allows for the user to input:A standard fixed rateA blocked charge rateCustomer chargesDemand ratesCombined rates

11 Building Shell Components The building is constructed by first giving the program several values:Building Type,A rough estimate of the area,The number of floors, both above grade and below,
12 Building FootprintThe total building area can be laid out and ploted using a simple CAD drawingZones can also be plotted by whatever boundaries the user specifies.
13 Building Envelope Construction Walls and roofs can be modified by selected form a list of components:Frame type and O.C. specificationsExterior finishExterior and Interior insulationAdditional insulation, commonly batt insulationThe ground floor can be constructed similarily from lists of components:Exposure, such as Earth Contact or Adiabatic SpaceInterior finishConstruction, such as slab thicknessExterior insulationInfiltration is also specified on this input screen
15 Interior Construction: Walls, Ceilings, Doors and Windows Insulation and finishes can be specified for interior surfacesDoors:Up to three different types of doors can be specifiedDoors can be glass, opaque or numerous other typesOnce a type of door is selected, materil components can then be selected as wellFrame type and widthNumber of doors per exterior wallThis will be omitted for our design for now
16 Interior Construction: Walls, Ceilings, Doors and Windows Up to three different types of windows can be selectedOnce a type of window, materials can be chosen, ranging from single pane to triple pane windowsEach window can have a specific size, frame type and widthWindows can be placed on exterior walls by giving a percentage of the wall that is windowThis will be omitted as well
17 Custom Window and Door Placement Windows and doors in our analysis will be placed in a custom arrangement.This gives the design a wider range of window sizes than with the preset sizes.It also allows us to place the doors on the appropriate exterior surface.
19 Several Other OptionsBlinds can be applied to a set of windows or to one side of the building, as in the case of the Willet Center.Blinds can be set to partial visibility or full transparencyShades and overhangs can be applied to any windowRoof skylights may be applied to different zones to help customize a building.A typical operation schedule can be given with opening and closing times.
20 Activity Areas Allocation Areas of the building can be designated as a specific type.An area percentage is given for each typeA ventilation requirement for each areaAreas are then givena core or perimeterassignment.Occupancy Profile
21 Zone Group Definitions Now that each area is defined, each area is assigned to a HVAC system and a zoneThis is done based on percentage of area that system covers
22 Non-HVAC End-usesMany different end-uses can be chosen at this point, both internal and externalAmbient, task and exterior lightingDifferent equipmentPumpsMotorsDomestichot water
23 Lighting Loads and Profiles Once lighting is chosen as an end-use, a new screen and inputs becomes availableEach area is given a power per area (W/sqft) of lightingAn hourly profile can also be described
25 Developing the ModelThe opening Design Development Wizard has several options:Project/Site/UtilityEdit Building ShellEdit Air-Side SystemHW Plant Equipment
26 HVAC SystemsOnce the HVAC system is given a name, it can begin to be definedA cooling andheating sourceis selectedSystem type andassignment todifferent zones isselected
27 Temperatures and Air Flows This page allows the user to select thermostat points for cooling and heating.Occupied and unoccupiedDesign TemperaturesA minimum air flow is also given
28 Packaged EquipmentThis is where the heating and cooling elements are given specificationsThe loads of the equipment and the efficiency can both be entered(heating is requested, but not present in this screenshot)
29 System FansThe only system fan for our model is the supply fans that are built-in the two rooftop unitsPower, efficiency, fan flow and outside air ratios
30 Other Specifications Fan Schedule Operating times during occupancyNight time run optionContinuous run time or intermittentHVAC Zone Heating, Vents and EconomizersZone heating for the exhibit is baseboard heatingThere are no vents in our modelAn economizer can be selected to run with the RTU to help minimize energy costs
31 Developing the ModelThe opening Design Development Wizard has several options:Project/Site/UtilityEdit Building ShellEdit Air-Side SystemHW Plant Equipment
32 Heating Primary Equipment The heating system type is first selectedNumber of boilers and pumpsThe configurationThe boiler specifications can then be selected.
33 HW System Control and Schedule The maximum and minimum set temperatures for the boilers can be selected hereSchedules for typical run time for the boilers are also given
34 Now that the construction of the model is done…
39 Simulated Building Performance The program is equipped to handle multiple EEMs and a baseline.It is able to calculate daily values for energy consumption based on the building and the HVAC system inputs.It downloads weather data history from the internet.Once the simulation is performed, several reports are available
