    Why is Savings greater than the annual usage?

    Follow

    The Savings is greater than the annual usage message may display on the Energy Savings Screen, a Work Order Screen, or the Modeling Report Screen.

     

    Work Order or Energy Savings Screens

    When this is displayed on the Work Order or Energy Savings screen, it indicates that the Modeled pre usage (primarily the heat loss for heating season and heat gain for the cooling season) is smaller than the Modeled Post Usage. The Energy Savings is  calculated by subtracting the kwh, therms and mmbtu of the modeled post usage from the modeled pre usage. 

    The energy modeling engine calculates load on individual building components by using bin analysis methodology from ASHRAE.  It does not use the numbers entered on the energy consumption screen. 

     

    How to fix the issue:

    -One way to quickly determine the root of the problem is to look at the Energy Savings Screen. Look for numbers that are larger or smaller than expected. 

    - Verify that the WAP > Audit Information Screen numbers reflect the house dimensions, and that the total sq feet calculation is reasonable.

    - Review the energy audit screens for typos or incorrect data entry. There may be an incorrect quantity on a measure or incorrect size of a wall, attic or basement section.

     

    Modeling Report Screen

    Unlike the Energy Savings screen which relies 100% on modeled data, the Modeling Report screen does have an option to compare the data entered on Client Intake > Energy Consumption to the modeled energy savings calculations.

    The Energy Consumption values are entered as an annual or monthly consumption, then values are assigned to different subsytems (DHW, heating, cooling and baseload.)  The only place the values are used is on the customer education report (modeling report), the values are not used in energy modeling calculations.

    To view the User-entered values on the Modeling report, select the value "Actual" from pull-down option at the top of the Report Screen.

     

     

     

    This Report is only used as a way for the auditor to true up the modeled pre-usage to the user entered (aka billing) pre-usage and to educate the client. The annual usage entered by the user does not affect modeled savings.  
     
     

    How to fix Modeling Report Energy Usage issues:

    - Verify that the Client Intake > Energy Consumption numbers reflect the Client House Bills.

    - Verify that the WAP > Audit Information Screen numbers reflect the house dimensions, and that the total sq feet calculation is reasonable.

    - Review the energy audit screens for typos or incorrect data entry. There may be an incorrect quantity on a measure or incorrect size of a wall, attic or basement section.
