Note: In the spring on 2012, the city of Frisco was working to update the residential requirements. No official city council action had been taken at the time this summary was updated. Check program web site for current status of updates.
The city of Frisco administers a green building program with separate rules for commercial and residential structures. The programs are governed by separate ordinances passed at different times although both were amended in October 2006 with updated building information. Each also contains other environmental related restrictions in addition to energy efficiency requirements.
The residential green building program began in 2001 under Ordinance No. 01-05-39, which required that all single-family residential structures platted after May 31, 2001 receive the EPA Energy Star designation for energy efficiency. The original ordinance was amended in 2006 with additional requirements for structures with building permits filed after June 30, 2007. These new structures are required to be meet Energy Star specifications with a score of 83 or lower on the Home Energy Rating System (HERS) index. An Energy Star designation requires a HERS score of 85 or lower. The amendment also requires:
- Every home be tested (i.e., no batch testing) by an accredited Residential Energy Services Network (RESNET) HERS inspector, who must register annually with the city;
- Every story have at least one programmable thermostat;
- Air distribution system joints be sealed with duct mastic;
- Pressure differential between closed-off rooms and the location of the central air return not exceed ±3 Pa;
- All structures meet ASHRAE Standard 62.2 and other indoor air quality standards;
- Compliance with the city landscape ordinance (water conservation); and
- Construction waste recycling
Over 16,246 green homes have been built since the inception of the program in 2001. On average, the program saves households $436 or more in utility expenses each year and has avoided over 38,505 tons of CO2 emissions (statistics provided by the City of Frisco).
The commercial green building program was initiated in May 2004 under Ordinance No. 04-05-41, which required that all non-single family developments of greater than 10,000 square feet complete the United States Green Building Council (USGBC) Leadership in Energy and Environmental Design (LEED) checklist. There were no compulsory building requirements in the initial stages of this program. The law simply required the checklist data be submitted to city planners for one year (beginning Sept. 2004) in order to determine the effect of such a program on private development. This ordinance was repealed in Oct. 2006 in favor of a new ordinance defining design requirements for all non-residential and multifamily dwellings sited on or after Nov. 27, 2006. The new ordinance requires that 100% of all roof areas comply with the EPA Energy Star Cool Roof Program as it exists or may be amended, and that buildings fulfill specific heat island mitigation, water conservation, and construction waste recycling standards.
As of July 2012, over 7,310,340 square feet of "green" commercial space has been built (statistics provided by the City of Frisco).
