SolarWall Delivers More Heat


A SolarWall 2-Stage system can out perform 

an equivalent single stage SolarWall heater by up to 

50% in high-wind conditions and deliver temperature


rises up to 50°C (90°F) over ambient. After the air passes through the first stage of standard SolarWall system, the solar preheated air rises to a narrow cavity between the glazing and the second 

SolarWall section. The preheated air then passes through a second


set of SolarWall perforations, further increasing the temperature. After the second stage of heating, the air travels to the fab inlet or HVAC unit as it would with the single stage SolarWall system. By incorporating a two stage system, the air passes through the perforated panels twice which dramatically increases the heat gain.

LaFontaine Chevrolet Selects Ciralight

LaFontaine Chevrolet, well known for its environmentally friendly dealerships, selected the Ciralight Smart Skylights to be part of its new showroom. The active skylights provided a way to provide abundant light at no cost. Says Jason Bloom, of Bloom Engineering, who helped to specify in the lights, the Ciralights offered us a way to provide a balanced level of lighting with little or no heat gain or glare for more hours per day than any of the alternatives. Even though they are only providing sunlight, they appear almost like a strong electric light. They are a subtle reinforcement to LaFontaine’s strong commitment to energy conservation.

Bio PCMat Installed at Portland State University

Ciralight Global Completes Major Sale to Caterpillar Belgium

Ciralight Global (OTC:DB:CGHA), developer and manufacturer of the patented energy saving Ciralight SunTracker, and the only global provider of solar powered daylighting products capable of turning off electric interior lights for up to 10 hours a day, reported today that its European Division, Ciralight Europe, has concluded a deal to install its solar powered Ciralight SunTracker daylighting system at the headquarters of Caterpillar Europe, in Grimbergen, Belgium with installation set for the first week of January, 2012. 

“Caterpillar EMEA, Grimbergen, is one of the leading companies in Europe with over 89 branches,” said Alain Dujardin, Business Manager International EPS - Ciralight Europe. “Although the Company has made hundreds of installations around the world, the sale to Caterpillar is being seen in Europe as a pilot project and we expect that Suntracker will become the standard in all future Caterpillar construction projects and will be specified for retrofit in existing buildings.  

“Caterpillar engineers compared the cost of installing solar panels to the ROI of Ciralight Suntrackers as presented by Ciralight,” continued Dujardin, “and decided there was more value in installing high efficiency and lower cost Suntrackers, which use solar powered GPS technology and mirrors to track the sun throughout the day to illuminate building interiors with abundant natural daylight. Others members of the EMEA are observing and are interested in this installation and the results, which will be obvious soon thereafter"

bioPCmat™ Selected As Top 10 Product at Greenbuild 2011, a weblog devoted to the future of design selected bioPCmat as one of the top products at the prestigious Greenbuild Show in Toronto. In their review they point out, “BioPCM is not an insulation, but rather is used with insulation to regulate temperature more efficiently than by simply increasing insulation mass. For example, these sheets are comparable to using 12" of concrete as a thermal barrier, but are lightweight, flexible, thin, and easily installed.” Read more.

 February 15, 2011:  Los Angeles, California
Los Angeles Mayor Antonio Villaraigosa announced Monday at a special press conference the launch of a new City program that will eventually seek to retrofit every City of Los Angeles building with energy efficient products and implementing innovative renewable technologies.

LA Mayor Villaraigosa Speaks at Vineyard Recreation Center:
Surrounded by community leaders, City Department heads and supporters of creating Green Jobs at the Vineyard Recreation Center in Los Angeles, The Mayor unveiled the details of the City's new retrofit program and some of the green products the city will be using to make the City more energy efficient, including Ciralight Global's energy saving Smart Skylights.

Ciralight Global's Smart Skylight On Display at Press Conference:
Ciralight Global's Smart Skylights are a Solar Powered Lighting Solution that provides FREE light for buildings and will allow the City to shut off costly electric lights during daytime hours.

This could cut lighting costs for the City by as much as 50-80% resulting in huge cost savings. Smart Skylights utilize solar powered GPS technology and mirrors to track the sun throughout the day and bring high levels of natural light into buildings. Smart Skylight users can shut off their electric lights for up to 10.5 hours per day.

The result is a bright, abundant healthy natural free source of light, just as nature intended.

Smart Skylights are already being used by some of the Country's largest retailers, businesses and school districts including Whole Foods, IKEA, Boeing, Johnson & Johnson, Emerson, LG, Frito Lay, LAUSD, Los Angeles Community College District, Staples, Office Depot, Sky Harbor Airport, The US Navy and more.

Studies show that people thrive in naturally lit buildings including higher work productivity, less absenteeism, higher test scores in schools and increased sales in retail stores. Due to energy savings and tax and utility incentives, the Payback period for Ciralight's Energy saving Smart Skylights are typically between 2-3 years and provide more energy savings than installing Solar Panels.

The Press Conference was attended by Jeff Brain, CEO of Ciralight Global and Best Contractors, a Ciralight Global Dealer that serves as a contractor for the City of Los Angeles. Jeff Brain stated, "Due to the economy, the City of Los Angeles will not be building many new buildings in the near future.

This program however, recognized the value to go back and make the thousands of buildings already owned by the City more Energy Efficient and to cut future costs for taxpayers. Ciralight Global Smart Skylights are the perfect new green product for Los Angeles and other cities looking to reduce energy costs."

Ciralight CEO Jeff Brain Introduces the SunTracker to Villaraigosa:
Watch for Ciralight Global's energy saving Smart Skylights as they begin appearing in Los Angeles' facilities to bring renewable, sustainable energy savings to the City of Angels.

Green Tree Products and Technologies completes screen testing of its first high capacity thermal storage system using Phase Change Energy Solutions ThermaMat products.  It was developed in partnership with YourSolarHome, Inc.  Canada's largest manufacturer of solar air heating systems. Our two systems work in tandem. On one sunny winter day, our systems can collect and store enough excess heat from YourSolarHome's SolarSheat solar thermal collector to heat a small home/garage throughout the day and still deliver 5,800 BTUs of heat after the sun has set.  

With the enhanced Solarsheat and thermal storage products in development, a 20% increase in both the collected and retained heat from the sun will be achieved.  We are now looking at making a variety of configurations off this basic product platform for YourSolarHome and other international partners.
