Lesson 1 - Final Review

17 questions

  1. In Exercise 1, if the VAV system was changed to a single zone system, and everything else stayed the same, how many rooftops would be modeled?

    4

    10

    6

  2. The rooms tab in create rooms contains the data entered in the thermostat tab of create templates.

  3. If templates are used properly, it is likely that most rooms will only require data entry in single sheet tab of create rooms

  4. It is important to enter the exact length and width of a room in the single sheet tab of create rooms

  5. If a room has a slab on grade floor, and that room has 10 rooms per zone entered under the rooms tab of create rooms, that room will be counted ten times but the floor will only be counted once.

  6. When a floor multiplier is used, all rooms must be on the same system

  7. Multiple miscellaneous loads may be added to a room under the internal loads tab of create rooms, but under create templates --> internal loads, it is only possible to add one miscellaneous load

  8. Match the field to the appropriate field in create rooms. For example, wall construction type would be matched with walls, since it is under the walls tab of create rooms.

    Room mass/avg time lag

    Lighting Schedule

    External Shading

    Slab on Grade Floor

    VAV minimum

    You lose points by selecting incorrect options. You may leave an option blank to avoid losing points.

  9. Match the following fields with their corresponding definitions

    Supply air

    Partitions

    Cooling driftpoint

    Ventilation

    Walls

    You lose points by selecting incorrect options. You may leave an option blank to avoid losing points.

  10. In the equation Sensible load = 1.085 * cfm * (T1 - T2), the number 1.085 is called the density specific heat product (DSHP). This number changes based on elevation and other factors. Trace uses this number to calculate the sensible load. In exercise 1, what DSHP did Trace use? (Hint: it is located in one of the first three reports in the upper left quadrant  of the design reports)

    1.11

    1.03

    .997

    1.056

  11. What design report gives you a list of all equipment modeled?

    System Checksums

    Room Checksums

    System Component Selection

  12. Which of the following reports gives the size of the ROOFTOPS heating and cooling coil? (The preheat coil is on the rooftop)

    Room Checksums

    Zone Checksums

    System Checksums

  13. The size of the rooftop cooling coil can be accessed by the same checksum report regardless of system type?

  14. Match the variable with the appropriate report:

    Heating coil size on the vav box

    Minimum airflow in the Principal's office

    Density Specific heat product to perform hand calculation of supply airflow

    VAV supply air temperature

    Peak and block Cooling capacity

    You lose points by selecting incorrect options. You may leave an option blank to avoid losing points.
