Energy codes/insulation standards

Region tab on model data at Site level

You can select the Mandatory energy code in force as well as three additional levels of reference insulation standards to represent buildings with 'Uninsulated', 'Stock average' and 'Best practice' construction standards.

This data is used:

• To identify the mandatory energy code in force in the region. When one of the ASHRAE 90.1 codes are selected this has a significant knock on impact on the rest of the model as described in the ASHRAE 90.1 Modelling section.

• To set the insulation levels used when the 'Pre-design' Construction and glazing Model option is selected.
• When calculating asset ratings.
• Defines the Fuel emissions factors for the region.

Note: If you change any of this data, the insulation standards of the constructions in the <System> category will be automatically updated.
