Note: This refers to the older version of the software (v6.1).
When creating a Code, you may input a value for Overall Building Performance. Some regions/countries may use a total building fabric method for compliance instead of elemental values (walls, floors, roof and glazing). If no value is input for Overall Building Performance, a default value of 0.39 W/m2K will be used for metric models and 14.56 ft2 F hr/BTU for imperial models. This may always be edited.
This method will only be used if the option Overall Building Performance is unchecked.
Note: Any missing inputs will use the default values, so it is recommended to check that all boxes are filled when creating and saving your new Code.
To apply a value for Overall Building Performance, uncheck the box and input a value. The value for Minimum Overall Performance in the Performance Area will update to display this value.
