Info You’ll Need Basic information about the builder and project Area take-offs for exterior walls, fenestration, roof/ceiling, basement walls, floors, etc. Insulation R-values, fenestration U-factors, etc. Lighting fixture details Heating and cooling system details Service water heating details 16Building Energy Codes Program

Project Screen 17Building Energy Codes Program

Project: Code and Location Appropriate Code 18Building Energy Codes Program Location

Project: Project Type New Construction Addition Alteration 19Building Energy Codes Program

Project: Alteration project type explained Projects involve changes to or replacement of Existing building components that are part of building envelope Lighting, heating, ventilating, air conditioning, and water-heating equipment Specify only those envelope components, lighting fixtures, or mechanical systems/equipment that will exist upon completion of the project Alteration detail dialogs Specify exemptions if applicable Additional qualifications may be required (e.g., Window/wall ratio) Compliance shown as Pass/Fail for Envelope and Lighting 20Building Energy Codes Program

Compliance Options (IECC only) Efficiency Options High performance power (2012/2015) Reduced lighting power (2012/2015) On-site renewable energy (2012/2015) High performance SWH (2015) Enhanced interior lighting controls (2015) Dedicated outdoor air system (2015) 21Building Energy Codes Program Air Barrier Options (climate zone dependent) Air barrier permeability Assembly permeability Air leakage test

Project: Project Details Optional Sections Title/Site/Permit Owner/Agent Designer/Contractor Included on report 22Building Energy Codes Program

Project: Building Envelope Area Types Primarily impacts envelope compliance Whole building types that describe the envelope (separating conditioned and unconditioned spaces) Space conditioning type Nonresidential Residential Semiheated (no mechanical cooling) – 90.1 only 23Building Energy Codes Program

Project: Interior Lighting Method and Area Types Method determines lighting power density and allowances Area category allows for more detailed space representation 24Building Energy Codes Program

Interior Lighting: Methods Selected method determines lighting power densities in interior lighting and exterior lighting screens based on code, method, and applications selected on the Project screen 25Building Energy Codes Program

Project: Exterior Lighting Area Types Zone and area type determine: Lighting power density Units Tradability 26Building Energy Codes Program

Exterior Lighting: Tradable Applications Common applications where ‘unused’ allowable power can be traded where needed (e.g., driveways and entry ways) Based on length or area of application then summed 27Building Energy Codes Program

Exterior Lighting: Non-Tradable Applications Less common applications that cannot be traded, “use it or lose it” (e.g., building façade lighting, ATM stations) 28Building Energy Codes Program

Envelope Don’t have to use every assembly type Can group “like” components Gross area (except slab-on-grade) Use “Other” assembly as needed 29Building Energy Codes Program

Envelope: Fenestration NFRC site-built certified product Performance evaluated (per NFRC guidelines) Energy code defaults 30Building Energy Codes Program

Envelope: 2015 IECC Fenestration Requirements Menu View->Glazing Requirements 31Building Energy Codes Program

Envelope Helpful Hints (con’t) Cavity R-value – used for insulation placed between structural members Continuous R-value – used for insulation that is continuous across the structure (e.g., rigid insulation) After you’ve entered building components, look at compliance result Look for fields with red text If TBD, look for missing data 32Building Energy Codes Program

Lighting Compliance 33 Exemptions Mandatory Requirements (Interior and Exterior) Controls Switching Interior Lighting Power Limits Whole Building Additional Allowances + Efficiency Space-by-Space Exemptions Exterior Lighting Power Limits + Total Connected Power Interior Lighting Power Allowance < OR Tradable Non- Tradable Total Connected Power Exterior Lighting Power Allowance < Building Energy Codes Program

Interior Lighting: Spaces and Fixtures Select space then Add Fixture button or Fixture Library Fixture library preserves frequently used fixtures for future use Allowed/Proposed wattage balance maintained 34Building Energy Codes Program

Lighting Fixture Categories Linear fluorescent Compact fluorescent HID Incandescent Halogen Track lighting LED Induction 35Building Energy Codes Program

Lighting Helpful Hints Fixture wattage (helpful hint) In desktop, you can right click in fixture wattage to insert a default wattage value (not available for every fixture, however) Fixture ID is optional Can associate fixture with lighting fixture schedule Fixture Description is optional Can help keep track of fixtures in the list, avoid errors and oversights, and facilitate plan review and inspections 36Building Energy Codes Program

Lighting: Exemptions and Allowances Options menu Exemptions Power for exempt fixtures is omitted from the proposed wattage Allowances Allowed wattage for building increased by allowable amount 37Building Energy Codes Program

Lighting: Exemptions and Allowances - Hint Include ALL fixtures (both exempt and non-exempt) in the project Helps clarify where exemptions have been taken and can streamline plan review and inspection 38Building Energy Codes Program

Exterior Lighting Based on code selected Mandatory requirements Exemptions 39 Total Connected Power ≤ Ext. Ltg. Power Allowance Building Energy Codes Program

Exterior Lighting: Example Lighting applications entered similar to interior lighting Pay attention to tradable versus non-tradable criteria. 40Building Energy Codes Program
