Zero Energy/Zero Carbon

The Sustainable DC and Clean Energy DC initiatives have established a comprehensive energy and climate strategy, aiming for a 56% reduction in emissions by 2032 and carbon neutrality by 2050. This strategy promotes innovation, efficiency, and resilience through progressive energy policies. It outlines necessary measures in building practices, energy systems, and transportation to achieve the district's rigorous greenhouse gas (GHG) reduction goals by 2032.   

To help support these objectives, the Construction Codes Coordinating Board (CCCB) established alternative compliance paths for the 2017 DC Energy Conservation Code, which include options for meeting net zero energy or zero carbon program standards. Projects that comply with the net zero energy or carbon program standards will be recognized as meeting the DC Energy Conservation Code. This approach aims to reduce redundancy and bureaucracy for projects striving to achieve net zero energy or carbon compliance.  

The below is a list of alternative compliance pathways to the 2017 Building Code (Sections 101.10.6 and 101.10.7):

Projects subject to the Commercial Provisions of the DC Energy Conservation Code:

  • 101.10.6.1 Appendix Z. Demonstrate compliance with all sections of Appendix Z, with the exception of Section Z5.2 of the Energy Conservation Code—Commercial Provisions 
  • 101.10.6.3 Compliance utilizing ILFI Zero Energy Building. 
  • 101.10.6.4 Compliance utilizing PHIUS+ and on-site solar. 
  • 101.10.6.5 Compliance utilizing PHI and on-site solar. 
  • 101.10.6.6 Compliance utilizing LEED and LEED Zero Carbon. 
  • 101.10.6.7 Compliance utilizing LEED and LEED Zero Energy. 

Projects subject to the Residential Provisions of the DC Energy Conservation Code:

  • 101.10.7.1 Compliance utilizing ERI. 
  • 101.10.7.2 Compliance utilizing DCRA Residential Net-Zero Energy Program.  
  • 101.10.7.4 Compliance utilizing ILFI Zero Energy Building Certification.  
  • 101.10.7.5 Compliance utilizing the DOE Zero Energy Ready Home and on-site solar. 
  • 101.10.7.6 Compliance utilizing PHIUS+ and on-site solar. 
  • 101.10.7.7 Compliance utilizing PHI and on-site solar. 
  • 101.10.7.8 Compliance utilizing LEED and LEED Zero Carbon. 
  • 101.10.7.9 Compliance utilizing LEED and LEED Zero Energy.
