Lennar plans 1,254 more solar homes — SMUD, Roseville Electric aid effort |
SACRAMENTO BEE - March 17, 2007 - By Jim Wasserman - Bee Staff Writer Weeks after unveiling plans to build 650 solar-powered homes in Roseville, Miami-based Lennar Corp. said Friday it will build 1,254 more in the Sacramento region. The houses will start construction this year and continue through 2010 in the communities of Anatolia in Rancho Cordova, Village Greens in Natomas and Laguna Ridge in Elk Grove, said Jim Kauffman, vice president for purchasing at the home builder’s Sacramento division. Friday’s announcement propels Sacramento to the forefront of solar home construction nationally, said Kauffman, officials from a San Jose solar panel manufacturer and the Sacramento Municipal Utility District. “It’s a national breakthrough,” said Alice Perez, SMUD manager of residential service. The size of the building plan also will make the metro area a top solar player in a state where the technology has become a major government priority. California lawmakers and Gov. Arnold Schwarzenegger have declared a voluntary goal of I million new solar rooftops within a decade and set aside more than $2 billion to lower solar installation costs. California has about 2,000 new homes built with solar panels. The nation’s largest existing solar community is 466 homes in Orange County’s Ladera Ranch area. SMUD’s board of directors finalized the deal Thursday, approving $10.8 million in rebates to Lennar for installing 1,254 systems costing about $20,000 each. SM(JD has 230 solar systems installed on new homes and 680 in place on existing homes, Perez said. Lennar is getting $5.2 million from another public utility, Rosevile Electric, to install the homes with solar panels in Roseville. Solar systems are said to cut energy bills by up to 50 percent. The Sacramento region boasts about 320 days of sunshine yearly. Lennar’s Kauffman said the newly announced plan “definitely is the biggest in the nation. We are getting national attention for it, even from our own company. “Hopefully, we’ll see the marketing advantage of doing it in every home,” he said. Leimar is one of the nation’s largest home builders and last year ranked second in the Sacramento region with more than 1,100 sales. The firm plans to start the first 174 homes this year. Despite a global shortage of polysilicon, a key ingredient of solar panels, Lennar will have no problem getting its supply, said Bill Kelly, who manages the new home division of San Jose-based SunPower Corp. The company will provide the panels. At least three other regional builders have started or built more than 300 solar homes in Sacramento, Roseville and Rocklin, including Premier Homes and Treasure Homes, both in Roseville, and Stockton-based Grupe Development. Los Altos-based Edenbridge Homes also is building a 47-home solar community in Vacaville, and Seastar Communities of Escondido is building an 84-home solar neighborhood in Redding. |

406.11 Tamper Resistant Receptacles in Dwelling Units, 2008 NEC Code |
A national survey of emergency rooms from 1991 to 2001 showed that 24,000 children under the age of 10 were treated for burns and shock from electrical outlets. Tamper Resistant Receptacles will be required in the 2008 code in all areas specified in 210.52. The additional cost per receptacle will be about fifty cents. The little doors inside the slots will prevent a single object from going in. The only way to stick something in is to push 2 things in at the same time like a 2 prong plug. Utah and Colorado are already adopting the 2008 code because of the new tamper resistant rules. The new GFCI’s for outside will be yellow, corrosion resistant, and tamper resistant. |

AFCI's and Heat Rise - Application Data |
|
New Information Arc Fault Circuit Interrupter (AFCI) breakers are listed to UL 489 and UL 1699. UL 489 covers overload, endurance and short circuit (including temperature). UL 1699 covers arc fault test requirements. Per UL standard 489 for molded case circuit breakers, the breaker is required to pass an overload test (50 operations at 600% rated current, not less than 150 amperes) followed by 100% rated current in open air with a temperature not to exceed 50°C rise over ambient at both line and load terminals. This temperature test may also be performed in an enclosure at 80% rated current and temperature not to exceed 65°C rise over ambient. (The handle shall not exceed 60°C.) What this means is that in a loadcenter with a 70°F ambient temperature, the temperature rise can be as high as 187°F and still meet UL operating parameters for the breaker. While the breaker functions properly to this temperature, it will normally be in the 80 – 120°F range due to the electronics in the breaker. |

Sacramento County takes the solar pledge |
|
(Feb. 13, 2007) Sacramento County Supervisors voted today to adopt a SMUD-proposed ordinance waiving permit fees for the installation of residential solar systems, and other local governments are preparing to follow suit. SMUD has been working with all of the jurisdictions in its service area to standardize the permit process and reduce the cost to homeowners in an effort to encourage and speed the adoption of solar energy systems. Establishing partnerships with local governments was a key recommendation made by a group of SMUD employees who served on the Leadership in Energy Efficiency, Demand and Environmental Resource Solutions (LEEDERS) team. The four-part plan calls for waiving permit fees for three years; standardizing permit applications for photovoltaic installations; over-the-counter reviews of applications the day they are submitted, and conducting post-installation inspections within 24 hours. These “best practices” were recommended in a study conducted last year by Robert Waste & Associates. “Sacramento County is obviously an important player because 40 percent of our customers live in the unincorporated area,” said Lois Wright, who has been coordinating the effort for SMUD. Photovoltaic systems provide clean, renewable energy, reduce customers’ electric bills, and lower the peak demand on SMUD’s energy resources on hot summer days when electricity is most expensive. The city of Elk Grove was the first jurisdiction to become a “solar partner” with SMUD when it adopted the District’s solar ordinance last month. The Rancho Cordova City Council last week asked its staff to prepare a solar ordinance following a presentation by Wright, and the council is expected to vote on the ordinance in the next three or four weeks. The City of Sacramento will take up the issue soon. Building officials from all seven local jurisdictions have been receptive to the idea of standardizing permit applications, Wright said |
