Utility Programs and Incentives for Zero-Energy Homes

There are many federal, state and utility tax credits, grants, rebates and other incentives available to support home energy efficiency and renewable energy systems. Although the incentives for efficiency and renewable energy are offered separately, they can often be combined to achieve a higher incentive level for zero energy homes. And a few Southwest utilities now offer incentives for highly efficient homes.

This section provides an overview and links to government incentives and utility programs for zero energy homes. Several types of incentives, including tax credits and rebates, are available for energy efficient technologies, renewable energy systems, or production of high performance homes. The incentives are summarized in the table below, followed by detailed program descriptions.

New Mexico

  • Sustainable Building Tax Credit
    SB 463, enacted in April 2007, established a personal tax credit and a corporate tax credit for sustainable buildings in New Mexico. The amount of the credit varies according to the square footage of the building and the level of certification achieved, as indicated on the following chart:
  • Residential Buildings:
    Rating Level Occupied SqFt Tax Credit/SqFt
    Build Green NM Silver or LEED-H Silver First 2,000 $5.00
      Next 1,000 $2.50
    Building Green NM Gold or LEED-H Gold First 2,000 $9.00
      Next 1,000 $4.45
    ENERGY STAR Manufactured Home Up to 3,000 $3.00

All rebate funds have been reserved through 2016.

To receive the tax credit, the building owner must obtain a certificate of eligibility from the Energy, Minerals and Natural Resources Department after the building has been completed. The Department will only grant certificates in any given calendar year until the equivalent of $5,000,000 worth of certificates for commercial buildings and $5,000,000 worth of certificates for residential buildings have been awarded in that calendar year. Further, no more than $1,250,000 of the annual amount for residential buildings can be applied to manufactured housing.

The taxpayer must then present their certificate of eligibility to the Taxation and Revenue Department to receive a document granting the Sustainable Building Tax Credit. If the total amount of a Sustainable Building Tax Credit is less than $25,000, the entire amount of the credit can be applied to the taxpayer's income tax in that year. If the credit is more than $25,000 the credit will be applied in increments of 25% over the next 4 years. If a taxpayer's tax liability is less than the amount of credit due, the excess credit may be carried forward for up to seven years.

For more information, see the Sustainable Building Tax Credit website.
