The ordinance based on the Mayor's Sustainable Building Task Force was passed by the city council on March 12. A pdf of the
Ordinance (200 G -0 3 -1 2 -0 1 7 9) is on line but sometimes it is useful to have a document in html format. Naturally it is very long. But you can follow the read more link below to the full text in html.
This text was copied from the pdf and put into Word using character recognition, so there may be some missing or garbled text in this version. If you need to be certain about the wording of the ordinance be sure to rely on the city's pdf which is signed by Mayor Hardberger and the city attorney.
On the city's pdf, quite a few sections are underlined. That underlining is not here. I'm not sure of the meaning of it. But until someone tells me otherwise I'll guess that those sections were revised between the draft and final stages.

ARTICLE XV. INTERNATIONAL ENERGY CONSERVATION CODE
PREAMBLE: The City of San Antonio supports the adoption and implementation of energy provisions that result in energy savings of 15% or greater than the currently adopted code in 2008 (IECC 2000 with 2001 supplement and ASHRAE 90.1 1999), the goal of 30% energy savings in 2012 over the currently adopted code in 2008 (IECC 2000 with 2001 sURplement and ASHRAE 90.1 1999), the goal of net-zero carbon by 2030 with the intent to provide flexibility to permit the use of innovative approaches and techniques to achieve the effective use of energy and to reduce greenhouse gas and ozone precursor emissions in San Antonio and which is not intended to abridge safety, health, or environmental requirements contained in other awlicable codes or Ordinances.
The City of San Antonio approves the goals of the following recommendations of the Sustainable Building Task Force:
That the Planning and Development Services Department. Office of Public Utilities within Finance, and the Office of Environmental Policy coordinate with CPS Energy and San Antonio Water System (SAWS) to evaluate a new construction residential and commercial financial incentive program to include the provision of specific rebates or other incentives, with an ultimate goal of achieving net zero carbon by 2030 and be designed to reward improved performance in a scaled fashion, within the current limitations of all applicable laws and regulations.
2. That the City of San Antonio create a marketing and education awareness campaign which is a unified comprehensive community-wide outreach effort supporting an advanced sustainable buildings initiative.
That CPS Energy and SAWS provide existing rebate and incentive information to the City of San Antonio to coordinate and promote incentives to provide one-stop information.
That the Planning and Development Services DeRartment, with assistance from the Office of Environmental Policy, provide information on sustainable building practices and incentives to encourage residential and commercial developers to exceed minimum code requirements and serve as a clearinghouse for green building information from a wide and ever-increasing variety of sources.
That the City of San Antonio Office of Environmental Policy coordinate education awareness with other agencies or organizations that include workshops. trainings, and seminars which will provide sustainable building practices for residential and commercial buildings that exceed minimum code requirements.
That the City of San Antonio evaluate the feasibility of offering a property tax exemption for new homes and tax abatement or phase-in for new commercial buildings that achieve high energy performance levels, including participation in a third party verified green rating system addressing residential and commercial building. Such considerations may include a minimum HERS score for residential buildings.
7. That the City of San Antonio evaluate the feasibility of offering an additional amount of property tax abatement or phase-in for new homes and commercial buildings that utilize on-site renewable energy.
8 That the City of San Antonio Office of Environmental Policy promote an annual San Antonio Green Leadership awards program to recognize all new residential and commercial builders, architects, and others that significantly exceed the minimum code and to post those names on the City's website and through additional public media outlets.
9. That CPS Energy and SAWS evaluate incentives and rebates to support energy and water conservation for programs that exceeds code and include such programs in a unified city-wide promotion.
10. That the City of San Antonio evaluate the feasibility of funding for incentives through the Planning and Development Services Department. which could include fast-track permitting and reimbursement of fees, within the limitations of the current enterprise organization structure.
11. That energy incentives be provided to achieve 30% or greater savings above the currently adopted energy code; and
12. That a Stakeholder Sustainable Building Committee (SSBC) be formed which consists of representatives of architectural, engineering, construction, development, green building and building code professionals. Among other duties, the SSBC would monitor the implementation of the recommendations of the Mayor's Task Force on Sustainable Buildings and meet as needed but not less often than every three years to review COSA sustainability energy policies and goals. The SSBC would measure periodic progress and recommend the establishment or modification of interim goals to attain agreed long-term goals. Interim and long-term goals would be evaluated and recommended for amendment as required on the basis of sustainable environmental and community benefits, return on investment and practical impact on the regulated community. In 2012 the interim goal would target 30% above the current code in effect in 2008 (IECC 2000 with 2001 supplement and ASHRAE 90.1 1999); incentives will increase proportionately to achieve greater savings. Finally, should the energy needs/uses of existing buildings be examined in the future, the SSBC would be charged with the responsibility to present recommendations to City Council.
