CASE STUDIES

L1163 Temple College Case Study
The Temple College campus, which is made up of residential, recreational, and educational buildings spreading over 114 acres, faced a serious energy challenge. With rising fuel costs and related global strains on fossil fuel resources, energy expenses were sharply increasing.

Temple College retained the services of Johnson Controls Inc. of Milwaukee, an energy services company, or ESCO, who determined that numerous large glass windows were contributing substantially to the campus' overall energy inefficiency. Johnson Controls determined that LLumar energy-control window films, which would significantly reduce summer solar heat gain and winter heat loss through these windows, should be an important part of an effective energy-saving strategy for the college.

Johnson Controls subcontracted the window energy-efficiency improvement responsibility to LLumar® and its area dealer, a highly-qualified specialist in energy-control window film technology. Using a Department of Energy building simulation model, DOE-2, an analysis led to the selection of LLumar E-1220 low-emissivity, or low-e, window film.

When installed on glass the LLumar E-1220 film reduces the solar energy passing through the glass by 79% and improves window insulating properties by as much as 30%. The Temple College window film project, 30,000 square feet in all, will return estimated annual fuel savings of $33,917 with a return on investment in approximately 3.6 years. There were some buildings with longer paybacks that could have been excluded, however, Temple wanted the campus' sleek modern buildings to have a uniform contemporary appearance. The individual building return on investment varied from 1.3 to 8.6 years, with 3.6 years being the cumulative net return. The savings were determined to be impressive: a 193 kW summer peak demand savings and an annual savings of 410,000 kilowatt hours.

In addition to the energy savings, LLumar E-1220 - an energy-control film and not a security or safety film - significantly improved occupant comfort levels, protected interiors from sun fading, and yielded a degree of increased safety, which was almost immediately demonstrated. In the course of some horseplay in one of the athletic buildings in which film had just been installed, one of the students was thrown into a three by eight foot plate glass window. He ended up wistfully looking up at broken glass held together by window film with only minor scratches. LLumar film certainly saved the student from serious injury that day!

L1164 Fresno State University Case Study
CPFilms is a member of the National Association of Energy Service Companies and the only window film manufacturer that has developed a specific program tailored to meeting Energy Service Company (ESCO) needs.

An ESCO is a business that develops, installs and finances projects designed to improve the energy efficiency and maintenance costs of facilities over an extended time frame. Energy-saving measures used by ESCOs often include high-efficiency lighting, motors, and heating and air-conditioning equipment, as well as metering and centralized energy-management systems. Reducing summer solar heat gain and winter heat loss through windows, by using energy-control window films, is also an important part of an effective building energy-saving strategy.

Fresno State University retained NORESCO, one of the largest energy service companies in the United States, to design and deliver a cost-saving strategy that would restrain ever-rising energy costs and that would pay for itself. NORESCO turned to CPFilms for a solution and through its dealer network they tackled the task.

Following an energy saving evaluation based on US Department of Energy standards and in partnership with the University and NORESCO engineers, 90,000 square feet of Vista Ambiance VE-35 low-emissivity (low-e) energy-control window film was retrofitted to buildings throughout the campus. The film rejects 69% of the total solar energy passing through the building windows and helps to significantly reduce related cooling loads and the need for operating air-conditioning equipment. The low-e film also improves window insulating properties by as much as 30%, which further reduces cooling loads in summer and helps reduce winter heating needs. An additional 10,000 square feet of film, LLumar RK-20, was installed on the exterior of the windows at the Educational Building, which for practical reasons could not be filmed from the inside. The LLumar film effectively rejects 80% of total solar energy reaching the windows.

The energy savings yielded by installation of these window films is a major contribution to reaching the contractual ESCO obligation of reducing total energy costs by 6%. Furthermore, the energy savings yielded by the film alone will pay for film and its installation in three years.

As an added bonus, with the film in place, the interior comfort has been greatly improved and the sun's harsh glare tamed, with glare reduce by as much as 80 percent.

L1228 The Preservation Society Case Study
The "Cottages" of Newport - stately summer homes set in the magnificent surroundings of Rhode Island Sound - are world famous for their grandeur and beauty, largely because of the efforts of The Preservation Society of Newport County. Built in the heydays of the late nineteenth and early twentieth centuries, the American palaces were a celebration of the new wealth of the world's leading industrial society.

The Preservation Society was founded in August 1945 with the intent of preserving Newport's architectural and artistic heritage by restoring and revitalizing Newport's outstanding properties. The Society today keeps eight properties open to the public, conducts an extensive education program involving the houses and furnishings and leads a beautification program for the spacious gardens and grounds. The interior furnishings of the houses are virtually irreplaceable. They include some of the finest examples of tapestries, portraits, wall panels, ceiling paintings, French and Oriental carpeting, fabric wall coverings and opulent bed linens.

Over the years the precious furnishings had begun to fade. Curator, Paul F. Miller was very concerned at the conspicuous deterioration and resolved to find a way to protect the unique furnishings from damaging sun light. In 1995 he retained the local solar control window film specialist to install Llumar Window Film, thus virtually eliminating the sun's damaging UV rays, the principal cause of fading. The film, Llumar N1050 and N1035, neutral in color, can scarcely be detected when in place on glass and does not impair the views afforded by magnificent windows or darken interiors. Additionally, the film reduces harsh sun glare and saves on energy by cutting down on heat loss and gain through glass.

The Breakers, a Renaissance Revival structure built without limitations of scale or expense by Cornelius Vanderbilt II, has already been treated with Llumar film as has the Alice Brayton House set in the impressive seven acre Green Animals, the innovative and most northern topiary garden in America. Installation of solar control window film is planned on a number of the Society's other properties including Marble House, Rosecliff and The Elms.

"Our Society is committed to the restoration, preservation and maintenance of historic Newport properties. We see them as a major link between Newport and America's past and we will not let them fade away." - Paul F. Miller, Curator, The Preservation Society of Newport County"

Going green? Economical Benefits of Residential and Commercial Window Tinting
There are numerous tools and products on the market that can help achieve the new administration's energy goals. This article is dedicated to the many benefits of adding solar control window film to existing windows. Glass is everywhere you look and everywhere there is glass energy is being wasted. Glass allows our heat to escape and our cool air to heat up. Heating and cooling either a building or home is part of life for just about everyone. Being able to reduce energy loss through glass can be a huge help to our environment and your utility bills.

Many people aren't aware of programs that have been in place for years that offer tax credits for adding film to their existing windows. With President Obama's new outlook on energy independence these credits are only going to get bigger. There are many different films we can use to fit a specific job or objective. We have films that are so discrete you can hardly tell anything is on the window. These films can block out 99.9% of harmful UV rays without sacrificing any cosmetic looks. If you're looking to block out the hot summer sun to help out your air conditioner we have reflective films that can drastically help keep your home cooler and cheaper. We have films for just about anything you could ever imagine. Hurricane film, Safety film to prevent break-ins, privacy film, decorative films, again we have it all.

For commercial applications the benefits are even greater. Imagine cutting your buildings true energy costs by 15%. Most large projects we have completed have seen the film pay for itself in 1 to 4 years. This is all possible by preventing the energy from escaping through the windows. The U.S. Department of Energy estimates that one-third of a typical building's cooling load is from solar heat gain through windows, and nearly 75% of existing windows are not energy efficient. By helping you meet LEED and Green building objectives, we can help you earn valuable Energy Star ratings in addition to reducing heating and cooling costs.

Reducing carbon emissions and energy consumption may benefit the environment, but LLumar window film also improves a buildings internal environment by eliminating hot and cold spots, reducing distracting glare, and rejecting more than 99% of harmful UV rays. Blocking these damaging UV rays can also help to protect the appearance and value of fabrics, furnishings and artwork - all of which can be irreparably damaged or faded by allowing the sun to pass through untreated glazing. Fine Line is the answer for all of your residential, vehicular, and commercial tinting needs.
