CSU Extension Cultivating the New Energy Economy

Filed under: Weatherizing and Retrofit — Tags: , — uswx @ 5:37 am

Algae farms may be on Colorado’s horizon, thanks to a partnership between Colorado State University and biofuel startup Solix. CSU Extension anticipates piloting algae production for use in research to investigate the properties of algae-produced fuels and combustion byproducts.

Extension is part of the team working on a five year grant with with CSU Engines and Energy Conversion Lab to develop algae biomass fuels. Extension will educate potential producers of algae based biofuels and plans to collaborate with producers on an experimental algae test bed in Colorado. They expect to be ready for field testing in year three of the project.

Agents are assisting communities with the latest information on implementing renewable energy options such as wind, solar, biomass, geothermal, hydropower and home or business energy efficiency. “Extension is perfectly suited and a natural fit in the overall New Energy Economy,” said Cary Weiner, CSU Extension’s Clean Energy Specialist.

On Sept. 11, 2010, Extension will present an educational event in Jefferson County on various home energy options including energy conservation and efficiency, solar PV and solar thermal, small wind and geothermal. The session will cover costs, incentives, payback periods. The event runs from 9 am to 10:30 am at the Golden Extension office on the Jefferson County Fairgrounds, 15200 West Sixth Avenue, Golden, Colorado. RSVP to Cary Weiner 970-491-3784 or cary.weiner@colostate.edu

Extension founded Clean Energy Strategic Initiative Team two years ago. The initiative is a team of Extension agents each focused on one new energy topic such as biomass, renewables, and energy efficiency. The team will broadly educate all extension agents on the basics of renewable energy so they know where to turn and where to find resources. Ultimately, they will become general information brokers to meet the needs of Colorado communities on energy issues.

Extension recently added 5 community energy coordinators to drive efforts helping towns, counties, residents and businesses become more energy efficient. They will serve the Morgan, Logan, Phillips, Sedgwick, Yuma and Washington, Gilpin, Clear Creek, Custer, Freemont counties and the San Luis Valley under a $220,000 energy efficiency and conservation block grant through the Governor’s Energy Office.

Dennis Kaan, Golden Plains Area Director for CSU Extension told the High Plains Journal that “The goal of the Community Energy Coordinators is to reduce the information barrier for Colorado citizens by providing them with access to simple and accurate information about energy efficiency and renewable energy opportunities”.

Extension energy efficiency outreach includes hosting weatherization training for contractors across the state. Air Sealing technician training will be offered in Frisco August 26, Steamboat Springs August 27, Monte Vista Sept. 18 and Fort Morgan. The first regional training in Montrose was held Aug. 20. The trainings teach contractors how to cost effectively improve the energy efficiency homes by reducing air infiltration and repairing insulation defects.

In 1914 Congress authorized land-grant Universities to feed research-based information to Extension agents in each county to serve local communities. CSU Extension has traditionally offered expertise in agriculture, horticulture, range, forestry, water, health, financial literacy, business management, community development and 4-H programs.

Colorado Weatherization Program Awarded Innovation Grant

Filed under: ARRA Stimulus, Weatherizing and Retrofit — Tags: , — uswx @ 5:29 am

The Colorado low income weatherization program has been awarded a $950,000 Weatherization Innovation grant to expand energy conservation strategies for low income households by installing in-home energy monitors. The Colorado grant is one of 120 awards from the Dept. of Envergy totaling $120 million in Recovery Act funding announced Aug 19 by Energy Secretary Dr. Steven Chu.

Three front range weatherization agencies, the Governor’s Energy Office, and private energy consultants will partner on a 1,600 home pilot to evaluate the effectiveness of home energy monitors as a tool to help homeowners reduce energy consumption.

The Governor’s Energy Office (GEO) said standard weatherization services typically save clients about 14% on their home gas bill and 5% of electric consumption. Common energy conservation measures include air sealing, insulation and high efficiency furnaces.

The GEO pilot targets energy use behaviors of the home occupants by installing home energy monitors to display real-time energy consumption. By giving instant feedback on energy consumption, GEO and research partners Symbiotic Engineering and Tendril, Inc, will evaluate how well the displays can help home occupants reduce energy consumption.

Three GEO weatherization partners Longs Peak Energy Conservation, Veterans Green Jobs and Arapahoe County Weatherization Division will install the home energy monitors in some 1600 homes in Arapahoe, Denver, Jefferson and Boulder Counties.

$90 million of the awards were made to 100 highly performing weatherization providers in 27 states to implement additional conservation strategies not previously offered to homeowners, including energy monitors, renewable energy, high efficiency hot water systems and ductless heat pumps.

$30 million from the weatherization program’s annual budget will fund 16 recipients will be used to demonstrate innovative approaches to weatherizing single family and multifamily homes, including strategies for improved indoor air quality.

Colorado has been recognized as one of the most successful states in achieving weatherization delivery with Recovery Act dollars, completing 7,500 home retrofits during the first year of stimulus funded energy efficiency.

Weatherization Underground: Crawlspace Retrofit

Filed under: New, Weatherizing and Retrofit — Tags: , — uswx @ 5:02 am

Crawspace retrofit is literally the low hanging fruit of energy efficiency. Three major energy savings strategies are seal ductwork, air seal holes in the building envelope and create a warm crawl space by insulating the foundation and adding a vapor barrier on the ground. This keeps floors warm, prevents pipes from freezing, and brings the hvac system inside of the thermal envelope.


Jordan Latva rolls out an R-11 FSC fiberglass roll faced with Foil-Scrim-Craft which reflects radiant heat and can be left exposed in many cases.


A major improvement to home performance is achieved by sealing leaky duct-work and Colorado has some of the leakiest ducts in the country. This “panned” system uses building framing to form part of the duct system.

Rush Hour for Denver Weatherization Crews

Filed under: New, Weatherizing and Retrofit — Tags: , — uswx @ 7:10 am

There is a traffic jam every morning on Canosa St at 6th Ave. as Weatherization crews for Denver and Jefferson counties load up on bales of cellulose insulation to retrofit homes for energy efficiency.

Veterans Green Jobs is the Weatherization sub-grantee for the federal and state program in Denver and Jefferson Counties.

Nick Massey, right, pulls bales out of a semi trailer as he helps his crew load their truck. Massey has been on the job for 3 months with Veterans Green Jobs.

The standard unit in weatherization is one bale of cellulose insulation made from recycled newsprint with boric acid added to discourage incects and mold.

Pack it tight… technicians cram bales together in the truck so they don’t shift on the way to the job site.

Cellulose insulation is blown into an attic by technician Ruben Avalos. Attic temperatures are often over 100 degrees in summer months and the protective suits add to the sweltering heat.  Avalos says he tries to finish the job without a break. “Once you come down, you don’t want to go back up”.

Home Energy Efficiency for Neighborhoods in Centennial Colorado

Filed under: ARRA Stimulus, Weatherizing and Retrofit — Tags: , , — uswx @ 9:00 am

US Weatherizing has selected Centennial, Colorado for neighborhood energy efficiency programs.

” Most of Centennial’s homes can benefit from simple energy efficiency measures such as air sealing, insulation and heating system upgrades. These measures can typically reduce home energy consumption 10-25%” said building analyst Brian Brainerd.

Centennial has many terrific neighborhoods with spacious homes built before energy efficiency codes. The energy savings can add up quickly for Centennial homeowners because bigger homes use more energy for heating, cooling and lighting

US Weatherizing delivers energy efficiency, efficiently, with neighborhood-centric services to analyze home energy performance and retrofit specifications.

“This is the low hanging fruit of energy efficiency”, says Brainerd. “Most of these improvements pay for themselves in three years or less. The typical home has air leaks equal to a six square foot hole open to outside 365 days per year. “We identify where home are losing energy and create a custom Home GreenPrint to guide energy improvements.”

In addition to saving energy and money, simple energy improvements will make a home more comfortable and address carbon monoxide safety issues with heating systems

It all starts with an energy audit to inspect the home and its mechanical systems. Right now, the Colorado Governor’s Energy Office (GEO) is offering $50 rebates for energy audits from US Weatherizing. These audits are also required for renewable energy rebates on solar pv or solar thermal systems.

“The net cost of an energy audit from US Weatherizing is $79 after rebate. Homeowners will receive a prioritized checklist of actions to immediately start saving energy, money and the environment” says Brainerd.
