 Prescriptive Approach                              Trade-off Approach
                                                   • Trade-off between components
• Simple, fast and easy                            • Provides design flexibility
• Generally most stringent                         • Requires area & U/R-factors

• Requires minimum input
• Based on climate and                                                Windows version or
  WWR
• Uses a prototype

                All COMcheck tools available from www.energycodes.gov
                             When does COMcheck apply?

Commercial New Construction, Alterations and Additions
 Commercial Buildings include all buildings except
     Single family
     Low rise multi-family < 3 stories in height


 State Dependent
     Not all states have the same code, some states have state-specific
      energy codes
     Check to see what code is applicable in your state and if COMcheck
      is accepted
     Status of State Codes

                            What Do I Need to Know?

Information you need to use COMcheck:
1. General Understanding of Windows-based Computer
    Programs
2. Basic Information about the Builder and Project to be
    Constructed
3. Building Plans including Exterior Wall Areas, Glazing
    Areas, Roof/Ceiling Areas, Basement Wall Areas, etc.
4. Insulation R-Values, NFRC Glazing and Door
    U-Factors, etc.
5. Lighting
6. Heating and Cooling System Efficiencies
7. Service Water Heating

Main Building Envelope
• Use the blue-on-white buttons at the top of the Envelope screen to
  create a list of building components present in your proposed
  design. Each component you select is added to the building
  components displayed on the Envelope screen.
• Gross area (or perimeter) of assembly components, cavity R-value,
  continuous R-value, assembly U-factor, construction details, SHGC,
  and/or projection factor are entered by the user.
                                                                       16
