WI$E Energy Conservation Series
Home Energy Efficient Design (HEED)
Evaluating Combined Heat and Power (CHP) Applications
CALLING FOR NOMINATIONS! The San Diego Regional Energy Office is seeking nominations for the San Diego Excellence in Energy (SANDEE) Awards. The program recognizes outstanding achievements in energy savings by a small business, medium to large business, government or institutional agency, nonprofit organization, and homeowner. Nominations must be received by Jan. 19, 2006
Correction. Last month's news bit "Chula Vista power plant slated to close" was not accurate. Instead it should have stated that Duke Energy is divesting power assets in California. The assets to be divested include Oakland, Monterey County, Morro Bay and Chula Vista, which together can produce 4,400 megawatts of electricity -- equivalent to powering 3.3 million typical homes. View the press release for more information.
New Appliance Efficiency Standards Issued. On Oct. 19, the Department of Energy published a final rule to codify 15 energy efficiency standards for residential appliances and commercial equipment. Seven of the new standards apply to lighting equipment, five to commercial equipment and the remaining three to distribution transformers, unit heaters and dehumidifiers. View the press release for more details.
California Grid Bottlenecks and Congestion Costs Drop. Improvements and upgrades to the power grid controlled by the California Independent System Operator (ISO) has saved California energy consumers nearly $54 million in just two months. This according to a Market Monitoring Report delivered to the ISO Board of Governors. Recent upgrades included the new 230-thousand volt transmission line from the Miguel Substation near Chula Vista to Mission Substation in Mission Valley. With ISO approval and support, SDG&E accelerated the installation and shaved about a year off the project timeline, reducing congestions costs by an estimated $50 million.

Aerosol sealant injection seals ductwork leaks from the inside out by pressurizing a duct system with a fog of sealant particles that are forced into the leaks. With a sealing rate of approximately 80%, it avoids the hassle of getting access to the exterior of the ductwork above a ceiling, while providing greater sealing coverage due to traditional inaccessibility.
Duct leaks in small commercial buildings are worth sealing, particularly when ducts are located above an insulated ceiling, because these buildings tend to be worse than a number of residential buildings investigated. Many of these small commercial buildings have not received adequate duct tightness testing during construction and/or after occupant space changes. In addition, a number of issues were found with duct system components downstream of Variable Air Volume (VAV) boxes.
Fan power consumption can be impacted by ductwork leaks, rising in response to the fan pressure differential and flow rate. For example, a 1998 report (representative of other findings) showed that a 15% duct leak resulted in a 40% increase in fan power for a typical VAV system. This does not include the impact of increased heat from the fan motor introduced into the airstream. Not surprisingly, the greatest benefits from reducing duct leaks occur during the cooling season.
“The vision of design, construction and operations data that freely and effortlessly pass from one software application to another without corruption or degradation often is smiled upon as a lovely, but impractical and even unreasonable idea. There are huge hurdles to the concept, yet the payoffs will be so enormous as to completely overcome the obstacles. It is only a matter of time, and that time is coming soon.”

New Building Energy Efficiency Standards
Changes to California's energy efficiency standards for residential and nonresidential buildings, known simply as Title 24, went into effect last month on Oct. 1. Projected to cut the state's peak energy use by 180 megawatts -- enough to power 180,000 average-sized homes, Title 24 is also expected to reduce the growth in electricity use by 478 gigawatt-hours per year and gas use by 8.8 million therms per year.
Now Showing! Bright Ideas for Saving Energy
San Diego County Television Network
To help educate the public about energy efficiency and conservation, the San Diego Regional Energy Office ( SDREO) presents Bright Ideas for Saving Energy, a half-hour television program of real-world practical tips on how energy conservation does not have to be painful or expensive.
Program Spotlight: Rebuild a Greener San Diego
Rebate application deadline on Nov. 30
Time is running out for residents who lost their homes in the October 2003 wildfires. The deadline for applications to receive up to $22,000 through the Rebuild a Greener San Diego program is less than 30 days away.
The California Energy Commission is responsible for developing and supporting Title 24, and the intent of the 2005 changes were to:
Here are a few of the changes to this year’s update:
Title 24 (short for Title 24, Part 6 of the California Code of Regulations) refers to California's Building Energy Efficiency Standards. They are updated every three years, regulate construction of residential and nonresidential buildings, and from an energy standpoint, represent the minimum thresholds legally allowed. Opportunities exist in exceeding these minimum requirements.
Established in 1978 as part of a legislative mandate to reduce California's energy consumption, the standards, along with standards for energy efficient appliances, have saved more than $20 billion in electricity and natural gas costs. Based on 2001 estimates, the standards in total will save $57 billion by 2011.
For more information on Title 24 and ways to meet or exceed the minimum requirements, call SDREO at 1-866-SDENERGY.

Bright Ideas for Saving Energy presents various no-cost, low-cost, and investment strategies for saving energy. For example, during winter turning down your thermostat to 68 degrees and under saves about five percent on heating costs for every two degrees you lower the thermostat. An additional 10 percent can be saved if you install a programmable thermostat.
The program is loaded with practical tips like these for residents looking to save money and for businesses trying to improve the bottom line. The simple steps suggested could save a third or more on your energy bill.
Hosted by local Fox 6 Weekend Weather Anchor Terry Burhans, Bright Ideas was produced by Grossmont College students as a summer school project under the direction of Adjunct Professor Barbara Ruland. “The quality of the production is professional grade all the way and we're very pleased with how well it turned out,” says SDREO Marketing Director Tom Geldner, who also served as the show’s executive producer along with Pat Zeitounian of the County of San Diego.
Bright Ideas for Saving Energy was made possible by a $10,000 grant from the County of San Diego Cable and Telecommunications Review Commission with major funding from SDREO's San Diego Energy Resource Program. The program will be shown at various times on the San Diego County Television Network (CTN). (Click here for show times). You can also check out a copy of the show from SDREO’s video library center.

Rebuild offers rebates and special discounts to residents rebuilding homes that are energy efficient and/or for the installation of solar photovoltaic ( PV) systems. Although homes do not have to be completed until Dec. 31, 2006, applications have to be received by Nov. 30, 2005.
The program offers two packages: 1.) Energy Efficiency ( EE) Rebates of up to $2,000 for building an energy efficient home; and the 2.) Solar ( PV) Rebate of up to $20,000 for the installation of a PV system. Residents can apply for one or both of the packages.
According to Rebuild Program Manager Dave Gordon, "While most of the fire survivors are aware of the Rebuild program, many don't realize that the Energy Efficiency Rebates of up to $2,000 can just about pay the full cost of the upgrades. When the energy savings are factored in, full payback can be in as little as one year. As fuel and energy prices continue to rise, people will need to do everything they can to save."
The $20,000 Solar Rebate, on the other hand, saves residents up to 50 percent in PV material and installation costs. Plus, there's a special offer right now from Kyocera Solar, Inc. where you save up to $4,000 on Kyocera solar panels.
