    Steps for Performing a Full House Audit on HEAT

    The HEAT app can download 30 jobs at one time, but best practice is to only schedule a few jobs at a time.  Recommendation would be to schedule only jobs that will be done in the next few days.

    For most weatherization screens, only one ECM measure can be selected for each section.  For attics, basements and walls, you can enter multiple sections and assign one ECM measure to each section.  There is no limit to the number of ECM measures that can be added on Air Infiltration.

    Creating Full House Audits requires a minimum set of data to calculate the Energy Savings report.  Once you have entered Client Information, and the client is approved for an Audit, make sure the Audit Type is set to Full House Audit and assign the auditor.  Download the job to the HEAT app on your iPad and complete the following data on the appropriate screens:

    Building Information

    • Make sure the Weather Location State and City are selected
    • Confirm Air Leakage values
    • Enter House Dimensions for all floors of the house
      • Basements should be entered as floor number 0; if the basement is not intentionally conditioned, check the box for Unconditioned Basement (in some versions of HEAT this check box is labeled “Basement”)

    Energy Consumption

    • Confirm Energy Consumption Information

    Heating and Cooling

    • Add existing heating system(s)
    • Add existing cooling system(s)
      • If there is more than one heating or cooling system the Usage Ratio for all units must = 100%
    • If heating or cooling systems are being replaced, mark as Removed and add new system(s)

     

    Zonal Distribution

    • For Ducts, select BPI or P-Pan efficiency model
    • For P-Pan, enter pressure pan test results.  For BPI select the existing condition of the ducts to determine the efficiency.
    • Identify existing heating/cooling system(s) for the distribution system

    Lighting

    • Select the appropriate appliance
    • Edit the Watts
    • Enter the Quantity


    DHW Measure Install

    • Select measures, like a shower head and enter quantity and price
    • "Choose this row to add a new entry" to add more measures


    Hot Water Tank

    • Enter existing tank data (Size, Pre Energy Factor, Pipe Length, Temperature and usage ratio)
    • Select replacement measure


    Attic

    • Enter sections and existing conditions (Size, R-value, Framing)
    • Enter attic measures
    • Enter vent measures


    Wall

    • Enter Walls (Length, width, orientation and existing R value)
    • Associate windows and doors for each wall
      • Windows and doors can be added on the Wall screen (Create Type)  or on the Windows and Doors screen, but must be associated with the appropriate wall(s) here

    Windows

    • Enter existing Windows  (Section name, width, height, total quantity and percentage glass)
      • Existing window sections include Double Pane, Double Pane w/ Loe, Single Pane, Single Pane w/ Storm, TP with LoE and should be defined as 95 percent glass
      • Existing door sections include hollow core, solid core and thermal ins
    • After creating windows and doors from the Windows screen, they must be placed on the appropriate wall(s) on the Wall screen. To do this:
        • Open the Wall screen
        • Tap Windows and Doors
        • In the Type Name field select the window or door to be associated with the wall
        • Enter the quantity of windows to be associated to a particular wall
        • Save and choose a new row to associate another window or door to the same wall


    Basement

     

    • No basement or crawl - Choose the section as Slab, select the framing, and enter the R value and length and width.
    • Conditioned basement -  1. Choose the section as Conditioned Complex, select the framing as Above Grade Concrete Block Wall, enter the R value and the perimeter (width) and height of the block wall.  2. Choose the section again as Conditioned Complex, select the framing as Basement Slab, enter the R value and the length and width of the slab or basement floor. 3. Choose the section again as Conditioned Complex, select the framing as Sill Joist Conditioned Basement, enter the R value and the width and height (length) of the sill joist area. Save and Close. Open the first wall entry and check off all associated components or framing options and save.

     

    • Unconditioned basement -  1. Choose the section as Unconditioned Complex, select the framing as Above Grade Concrete Block Wall, enter the R value and the perimeter (width) and height of the block wall.  2. Choose the section again as Unconditioned Complex, select the framing as Basement Slab, enter the R value and the length and width of the slab or basement floor. 3. Choose the section as Unconditioned Complex, select the framing as Below Grade Concrete Block Wall, enter the R value and the perimeter (width) and height of the block wall. 4. Choose the section again as Unconditioned Complex, select the framing as hardwood floor, enter the R value and the length and width of the floor above. 5. Choose the section again as Unconditioned Complex, select the framing as Sill Joist Conditioned Basement, enter the R value and the  perimeter (width) and height of the sill joist area. Save and Close. Open the first wall entry and check off all associated components or framing options and save.
    • Vented crawlspace -   1. Choose the section as Vented Crawl Space Complex, select the framing as Above Grade Concrete Block Wall, enter the R value and the perimeter (width) and height of the block wall. 2. Choose the section again as  Vented Crawl Space Complex, select the framing as hardwood floor, enter the R value and the length and width of the floor above. 3. Choose the section again as  Vented Crawl Space Complex, select the framing as Sills Crawlspace, enter the R value and the perimeter (width) and height of the sill area in the crawlspace. Save and Close. Open the first wall entry and check off all associated components or framing options and save.
    • Unvented crawlspace -   1. Choose the section as Unvented Crawl Space Complex, select the framing as Above Grade Concrete Block Wall, enter the R value and the perimeter (width) and height of the block wall. 2. Choose the section again as  Unvented Crawl Space Complex, select the framing as hardwood floor, enter the R value and the length and width of the floor above. 3. Choose the section again as Unvented Crawl Space Complex, select the framing as Sills Crawlspace, enter the R value and the perimeter (width) and height of the sill area in the crawlspace. Save and Close. Open the first wall entry and check off all associated components or framing options and save.

    Air Infiltration

    • If you choose the fan pressure and house pressure, the CFM will auto calculate.  If you leave the fan pressure blank, then you can directly enter the CFM@50.
    • Enter Target CFM50
    • Enter exhaust vents and run the ASHRAE 62.2-2013 calculator on Building Ventilation

    Selected Measures

     

    • Tap Selected Measures to review all measures

     

    Tap Energy Savings to see the results, and modeling report to see an example homeowner report
