Codes 101Understanding Building Energy Codes and
Standards
  • Rosemarie Bartlett
  • Pacific Northwest National Laboratory

Why Building Energy Codes Standards
  • National Level Impacts
  • Security
  • Environment
  • Consumption of Energy

Market Level Impacts Capital Costs Paybacks Consum
er Protection
3
Codes, Standards, and Model Codes
  • Code
  • Specify how the building must be constructed
  • Example State Specific Code (GA)
  • Standard
  • Describe how the building should be constructed
  • Example ASHRAE
  • Model Code
  • A general code that may be adopted by state or
    local jurisdictions
  • Often modified to reflect regional needs and
    practice
  • Example IECC

Code Adoption at State and Local Levels
Code into effect
Proposal Accepted
Process Initiated
Proposal Review
Proposal Modified
Proposal Rejected
Public Comments
Typically adopted with a grace period before
enforcement
Public hearings or notices
May be initiated by individual or relevant agency
14
Implementation of Energy Codes at State and Local
Level
Communication is KEY!!!
15
Code Enforcement
  • Energy code enforcement typically includes
  • Plan review
  • Product, equipment, material review
  • Testing and certification review
  • Calculation review
  • Building inspection during construction
  • Construction substitution review
  • Building inspection prior to occupancy

16
Code Enforcement
  • Codes may be enforced at the state, local or
    jurisdiction level
  • Enforcement is often done with limited resources
  • Voluntary Energy-Efficiency Programs may assist
    code enforcement
  • Home Energy Rating Systems (HERS)
  • Energy Star
  • Utility and Government Programs (LEED and Good
    Cents)

17
DOEs Support
  • Provide financial and technical assistance to
    adopt, implement and enforce
  • Participate in the development of codes and
    standards
  • Provide information and resources, compliance
    products, training and energy code related news
