In California, affordable housing projects applying for LIHTC funds must meet sustainability requirements set by CTCAC (California Tax Credit Allocation Committee) and CLDAC (California Debt Limit Allocation Committee).

CTCAC and CDLAC set sustainability requirements for affordable housing projects receiving financing. Minimum sustainability requirements apply to both existing buildings and new construction. For competitive applications, additional energy efficiency measures and green certifications contribute to points.

Partner Energy provides pre-application consulting services to assist developers, architects and contractors plan, design, and budget for these sustainability and energy efficiency requirements. We work with the entire team to map out a cost-effective path that benefits all stakeholders from property owners to residents. Our consulting services span the lifecycle of projects, from design and construction to ongoing operations.

CTCAC/CDLAC Requirements for Existing Buildings

  • All rehabs must achieve a 10% improvement in energy efficiency, as demonstrated by an energy audit.
  • Energy savings above 10% can contribute to sustainability points for competitive applications. Other items that contribute to sustainability competitive points include commissioning, renewable energy, green maintenance manuals, and water efficiency measures.

CTCAC/CDLAC Requirements for New Construction

  • All new construction projects must demonstrate compliance with California energy code through an energy model, as well as compliance with CTCAC’s minimum construction standards. 
  • Competitive new construction applicants have several paths towards points, such as:
    • Green certification, including LEED and/or GreenPoint Rated.;
    • Building above the energy code; and/or,
    • Offsetting tenant energy use through renewable energy.

Partner Energy has extensive experience providing green certification support, including LEED and GreenPoint RatedEnterprise Green Communities, NGBS, and WELL Building. In addition to green certification support, Partner Energy provides commissioning, support for other related funding such as AHSC, USDA, regional NOFAs and analysis for the California Utility Allowance Calculator (CUAC).
