    Seasonal Efficiencies Error - "Keyword out of range: Heat SSEFF

      Product(s): OpenBuildings Energy Simulator
      Version(s): CONNECT Edition
      Environment: N/A
      Area: Part L
      Subarea: N/A

    Overview

    If the efficiency figures of your systems are not entered correctly you may come across errors running the PartL calculation, such as:

    "Keyword out of range: Heat SSEFF"

    Method

    This error indicates that one of the Heating systems Seasonal Efficiency has been set to a very low figure. The heating systems should be examined and any incorrect efficiency figures should be changed to a sensible figure.

    In general, when there is no percentage character beside efficiency variables, these must be added as factors - eg 0.65 as below for Generator Seasonal Efficiency for a hot water.

     

    Other efficiencies allow for a percentage figure to be entered, as with HVAC heating efficiency below:

    On these, you can also find a dropdown to switch between percentage or ratio as you wish.
