MAYOR’S SUSTAINABLE BUILDING TASK FORCE
APPROVED RECOMMENDATIONS
APPROVED ADVANCED ENERGY CODE AND ADDITIONAL POLICY
RECOMMENDATIONS
Residential and Commercial Recommendations
This code shall regulate the design and construction of new buildings for the effective use of energy.
The City of San Antonio supports the adoption and implementation of energy provisions that result in energy savings of 15 percent or greater than current code in effect in 2008 (IECC 2000 with 2001 supplement and ASHRAE 90.1 1999).
All new residential homes shall have duct testing or have ducts in conditioned space.
All new commercial buildings shall incorporate Energy Star Certified roofs.
The City of San Antonio shall support the goal of net-zero carbon by 2030 through a periodic review of codes and incentives.
A stakeholder sustainable building committee shall meet every three years to review COSA sustainability policies and goals. Future committees shall measure periodic progress and establish/modify interim goals to attain the agreed ultimate goals. Interim and ultimate goals shall be evaluated on the basis of sustainable environmental and community benefits, return on investment & practical impact on the regulated community. In 2012 the interim goal shall target 30% above than current code in effect in 2008 (IECC 2000 with 2001 supplement and ASHRAE 90.1 1999); incentives will increase proportionately to achieve greater savings.
This improved code will take effect no later than January 1, 2010 to allow time for software availability, staff training, and public education.
The city energy code shall be publicly reviewed before March 1, 2012. After that date, it shall be reviewed, and amended as needed, every three years at a minimum.
The City of San Antonio Code Official shall be permitted to approve specific computer software (including at least one free, publicly-available source), worksheets, compliance manuals, and other similar materials that meet the intent of this code.
This code is intended 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. This code is not intended to abridge safety, health, or environmental requirements contained in other applicable codes or ordinances.
ADDITIONAL ENERGY POLICY RECOMMENDATIONS
Residential and Commercial Recommendations
A Stakeholder Sustainable Building Committee (SSBC) shall be formed which consists of representatives of architectural, engineering, construction, development, green building and building code professionals (similar to the membership of the 2008 Mayor’s Task Force on Sustainable Buildings, which created this document). Amongst other duties, the SSBC shall monitor the implementation of the recommendations of the Mayor’s Task Force on Sustainable Buildings, and shall meet as needed but not less often than every three years to review COSA sustainability policies and goals. The SSBC shall measure periodic progress and establish/modify interim goals to attain agreed long-term goals. Interim and long-term goals shall be evaluated and amended as required on
the basis of sustainable environmental and community benefits, return on investment and practical impact on the regulated community. Finally, should the energy needs/uses of existing buildings be examined in the future; the SSBC shall be charged with the responsibility to present recommendations to City Council or its designee.
ENERGY CODE COMPLIANCE
RESIDENTIAL BUILDINGS COMMERCIAL BUILDINGS
New residential/commercial construction energy usage must achieve an efficiency rate of 15 percent above the current San Antonio energy codes IECC 2001 (current State code as of 2008 ASHRAE 90.1 1999 & IECC 2000 with 2001 supplements) by complying with any of the following options:
1. IECC 2009 (as approved and/or amended by the City of San Antonio and/or Energy Systems Laboratory).
1. COMcheck or other software as approved by Planning and Development Services based on existing codes (ASHRAE 90.1 1999 & IECC
2000 with 2001 supplements) showing 15% or above the passing score.
2. Energy Star Certification Compliance. 2. COMcheck based on ASHRAE 90.1 2007.
A passing score satisfies the 15% standard referenced above.

A passing score satisfies the 15% standard referenced above.
4. Approved compliance methods as adopted by the State of Texas.
4. ASHRAE 90.1 2007 energy modeling analysis approved methods
This meets the 15% standard referenced above.
5. Build San Antonio Green, USGBC LEED-H, or other third-party certification program that meets or exceeds the energy requirements as approved by the Code Official shall be
considered in compliance.
5. ASHRAE Advanced Energy Design Guidelines
(Prescriptive documentation) This meets the 15% standard referenced above.

INCENTIVE RECOMMENDATIONS
Residential and Commercial Recommendations
A. It is recommended that the Planning and Development Services Department and the Office of Environmental Policy coordinate with CPS ENERGY and San Antonio Water System (SAWS) to provide a new construction residential and commercial financial incentive program. Such program shall include the provision of specific rebates or other incentives such as a reduction of impact fees for new residential and commercial buildings that exceed the City’s code requirement with an ultimate goal of achieving Carbon-neutrality by 2030 (using no fossil fuel GHG emitting energy to operate) and be designed to reward improved performance in a scaled fashion. (Example: A residential or commercial structure with a 50% improvement over code would be incentivized
proportionally more than a residence performing at 30% better than code when 30% above code is the incentive trigger point).
1. It is recommended 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.
a. CPS ENERGY and SAWS shall provide rebate/incentive information to the City to coordinate and promote incentives to provide one-stop information.
INCENTIVE RECOMMENDATIONS
Residential and Commercial Recommendations
b. The Planning and Development Services Department with assistance from the Office of Env. Policy shall provide information on sustainable building practices and incentives to encourage residential and commercial developers to exceed minimum code requirements and serve as clearinghouse for green building information from a wide and ever-increasing variety of sources.
c. It is recommended that the City of San Antonio Office of Environmental Policy coordinate education awareness with the Metropolitan Partnership for Energy and others that includes workshops, trainings, and seminars that will provide sustainable building practices for new residential and commercial buildings that exceed minimum code requirements.
2. It is recommended that the City of San Antonio evaluate and promote to City Council 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 “Build San Antonio Green” for homes only or an equivalent 3rd party verified green rating system addressing residential and commercial building. Such considerations may include a minimum HERS score for residential buildings.
3. It is recommended that the City of San Antonio evaluate and promote to City Council 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.
4. It is recommended 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.
5. CPS Energy and SAWS shall provide incentives, rebates and marketing to support energy and water conservation for any program that exceeds code and will include such program in a unified city-wide promotion.
6. It is recommended that the City of San Antonio evaluate and report to City Council on the feasibility of funding for incentives through the Planning and Development Services Department. This could include fast-track permitting and reimbursement of fees. The task force recognizes that current enterprise organization does not allow these incentives to be offered.
7. Energy incentives shall be provided to achieve 30% or greater savings above current energy code (IECC 2000 with 2001 supplement and ASHRAE 90.1 1999).
