25 Launch equest and select to create a new project via the Wizard Since this example project involves building footprints that are different in shape (1 st floor vs remaining floors), select to use the Design Development Wizard Name your project (this will become the file name, too). Select the Building Type as indicated. Select the weather location to be Seattle Washington. If this weather file is not on your machine, it will be automatically downloaded from the doe2.com ftp site when you start the simulation. Page 1 of 43

26 Accept default seasons: for multifamily, this is one season per year. Select Continue to Navigator to proceed to the DD Navigator. Use the DD Navigator to navigate between shellrelated screens and building services screens. Return to the previous screens by selecting Project/Site/Utility. Select Edit Selected Bldg Shell to begin the shell description. Page 2 of 43

27 This first envelope component will be floors 3 through 7. Specify the total area for floors 3-7 as indicated. Allow the number of floors to default (5 for midrise). From the Building Footprint screen, temporarily select the Zoning Pattern to be One per Floor. This will simplify a future step. Page 3 of 43

28 To create a custom floor footprint shape, from the Footprint Shape control, select custom To create a completely custom footprint, indicate blank slate. Set display extents as preferred. Check the Import DWG File control. From the DWG file import browse dialog, select to import the Level 3 Bldg Footprint & Zoning DW file. Page 4 of 43

29 DWG file drawing units can vary, however, 1 drawing unit = 1 inch is most common. Press Apply, then Close. This should result in an image similar to the one at right. Use the pan button (the 4- headed arrow) and zoom button (the magnifying glass) to size the display and position the DWG image to your satisfaction. Set/confirm snap priorities to trace around the image, set DWG as the 1 st priority. Page 5 of 43

30 Beginning near the lower left corner of the image, trace around the floor footprint by dragging the active vertex counterclockwise around the image. Let go of the vertex at each point you snap to. Once you have completed tracing around the floor image, click on the Done button. NOTE: You should not click on the origin to complete the trace Page 6 of 43

31 This image illustrates the completed custom floor footprint image with one zone per floor zoning. To initiate custom zoning, select custom form the Zoning Pattern control. Page 7 of 43

32 Similar to the building footprint process, select Blank Slate to create completely custom zoning. The whole floor image, ready to populate with zones, should appear similar to the image a right. Adjust the Polygon View Properties to give Polygon snap first priority. Increase the Snap Range for the polygon. Page 8 of 43

33 Click on Create New Zone, the starting at the lower left corner of the image, trace the first zone (counter clockwise) using the same drag-and-drop technique as before (let go of the active vertex at each new snap location). Continue adding new zones. Click on Create New Zone before each new zone. Page 9 of 43

34 Continue as indicated. Continue as indicated until the floor footprint is fully populated with zones. Click on Done to return to the main building footprint wizard screen. Page 10 of 43

35 The Building Footprint screen now shows the custom zoning pattern. Specify the Floor-to- Floor and Floor-to- Ceiling height as indicated. Saved as 7 th & Lane 01 Provide inputs as indicated for roof, exterior wall, ground floor (lowest floor for this shell), and infiltration. Page 11 of 43

36 Provide inputs as indicated for interior surfaces. For the purpose of this example, we will assume that there are no doors in this building shell component. Page 12 of 43

37 Select specify properties (see screen below), then indicate the NFRC U-Factor. Note that the glass properties inputs above the U-Factor field help determine the default U-Factor and SHGC. Describe the typical window width, height and sill height as indicated. Specify the windowwall ratio for the windows, by orientation, as indicated. From the Exterior Window Shades and Blinds screen (next page), select Seasonal Definitions, then specify up to three seasons, as indicated. Note that these seasons are different than the seasons specified in the Project & Site dialogs. Page 13 of 43

38 Modify the percent Blinds Closed as desired to account for occupant use of internal shading. No skylights are included in the example project. Page 14 of 43

39 Accept the default occupancy schedule (i.e., for multifamily, occupied 24 hours/day). Saved as 7 th & Lane 02 Modify the default activity areas and percent area allocations (as shown at right) see the following screen. Page 15 of 43

40 Eliminate unused activity area assignments by selecting select another as needed. Specify Percent Area as indicated. Use the Group Definitions screen to assign activity areas and HVAC systems to specific areas of the project. Start by deleting the existing (default) zone groups. Define two new zone groups (see the following screen). Page 16 of 43

41 Define two new Zone Groups (by clicking Create Zone Grp ). Assign zones to these Zone Groups by clicking on the preferred zone in the diagram, then selecting to assign the zone to the current zone group. Use this screen to indicate which non- HVAC end uses will be included in the project. Page 17 of 43

42 Specify lighting power as desired. Specify plug loads as desired. Page 18 of 43

43 This screen serves to specify the schedule profile to be used to govern hot water demands. Saved as 7 th & Lane 03 The description of the first shell component is now completed. To edit an HVAC system, click on Edit Selected System. Page 19 of 43

44 Specify the name and attributes for the heater systems serving the residential units. Note that most of the defaults for the inputs are sufficient. Indicate thermostat type to be consistent with City Light Built Smart requirements. Page 20 of 43

45 Allow the heating system to be sized by DOE-2/eQUEST. To allow DOE-2 to size the air flow, input a zero ( 0 ) for fan supply flow (cfm). Reduce the default total fan static pressure from 1 to 0.15, to be more representative of these small units. Page 21 of 43

46 Accept default system operations scheduling. Accept default values for baseboards ( none ), and zone ventilation fan power. Page 22 of 43

47 Hot Deck resets will not apply to this simple residential electric furnace. This completes the description of the first HVAC system type. Proceed to describe a second HVAC system type (rooftop gas packs to serve the public corridor areas, as indicated on the screens on the following pages. Page 23 of 43

48 Page 24 of 43

49 Indicating the typical unit size does not affect the automatically-sizing of the units, rather, it affects on the default minimum unit cooling and heating efficiency. Increase the default total fan static from 1.25 (the default) to 1.75 to better approximate the proposed installation. Enter a zero ( 0 ) for Supply Fan Flow to have DOE-2 size the unit(s) based on the hourly annual simulation loads. Page 25 of 43

50 Accept default system operations scheduling. No baseboards are specified. Accept the default provision for an airside economizer. Page 26 of 43

51 This completes the description of the second HVAC system. Proceed to describe the DHW equipment Saved as 7 th & Lane 04 Page 27 of 43

52 This completes the description of the building services systems in the project. Proceed to describe a second shell component (the first floor), as indicated on the screens on the following pages. Page 28 of 43
