Education


Smart schools look to Fläktgroup SEMCO to improve indoor air quality, provide historic preservation with efficient technology, and lead their schools in making an environmental impact with energy recovery. Read below for the unique solutions that empowered each school to achieve its specific goals.

Campbell Junior High School

Winchester, Kentucky

Project: Efficient solution needed for an HVAC Retrofit of 43-year-old school building

Product: 3fficiency - 2 5000-CFM Pinnacle DOAS units, 212 Juno-IQHC Active Chilled Beams, and 46 Neuton Pump Modules

Payoff: Indoor air comfort as well as temperature and humidity control were achieved using chilled beams. This project saved the school $147,000 in labor and installation and $33,000 in annual energy costs in comparison to the schools former system. The new system produced superior indoor air quality at a low noise level leading to increased attendance.

George Rogers Clark High School

Winchester, Kentucky

Project: Cutting-edge HVAC technology required to cut school operating expenses and taxpayer costs in the long run and provide a better learning indoor air quality environment for students and teachers

Product: Pinnacle, Juno - IQHC Active Chilled Beams

Payoff: George Rogers Clark High School’s (GRCHS) green design has lowered monthly utility costs while improving indoor air quality and comfort. The 300,000-sq. ft., Winchester, Ky., high school uses a geothermal-based chilled water loop combined with SEMCO chilled beams and Pinnacle dedicated outdoor air systems (DOAS) for its HVAC system. The building is recording 35% less monthly utility costs versus the 30% smaller conventional high school it replaced.

Carnegie Mellon: Stever House Dormitory

Pittsburgh, Pennsylvania

Project: Failed energy recovery wheels and poor indoor air quality required an immediate solution

Product: FläktGroup SEMCO True 3Å Wheel

Payoff: After retrofitting their energy recovery units with SEMCO wheels, Carnegie Melon had a 54% reduction in TVOC contiminants in the indoor air from the original silica gel wheels. The dormintory achieved LEED Silver and used the retrofit opportunity to test the indoor air quality to prove compliance with ASHRAE Standard 62 (Ventilation for Acceptable Indoor Air Quality). To achieve the same IAQ using the silica gel media, significantly more outdoor air would be needed - thus negating any energy savings of having a total energy recovery wheel.

Randolph Community College: Continuing Education and Industrial Center

Asheboro, North Carolina

Project: Recycling an outdated industrial factory into a LEED Gold showcase of the HVAC industry’s most innovative equipment

Product: Pinnacle Series, Chilled Beams, FläktGroup SEMCO True 3Å Wheel

Payoff: The Continuing Education and Industrial Center's (CEIC) comprehensive energy savings result in a six-year payback of the mechanical, electrical, and plumbing specification. The LEED 2.2 project’s HVAC equipment provided 7 of the total 41 credits submitted for LEED Gold certification. The CEIC became the first LEED Gold Certified building in Randolph County in June 2013. The active chilled beams allowed the retrofit to keep its 10-foot ceilings because of the reduced plenum height required for the installation.

Carnegie Mellon: Gates Hillman Center

Pittsburgh, Pennsylvania

Project: Energy efficiency and sustainable design practices were given the highest priority, with a goal of achieving at least a LEED silver. 

Product: Custom Variable Air Volume (VAV) systems with True 3Å total energy recovery wheels

Payoff: Energy savings associated with the recovery wheels were monitored and accumulated over the first year of operation. Savings in excess of $90,000 were documented along with numerous other important operational and environmental benefits. The systems offered valuable "Optimize Energy Performance" LEED points which helped the new center attain LEED Gold certification.

University of Maine: Folsom-Pullen Hall

Presque Isle, Maine

Project: A classroom building built in 1966 gets major upgrades and reduces its carbon footprint by 63%.

Product: FV-5000 ERV, True 3Å wheels

Payoff: The FreshAir Ventilator FV-5000 relies on FläktGroup SEMCO’s True 3Å total energy recovery wheel to recover both sensible and latent energy, not only reducing heating and cooling loads but providing humidification in the winter and dehumidification in the summer. As the wheel rotates between the opposing supply and return air streams, the higher temperature air gives up its sensible energy to the wheel’s aluminum substrate. A molecular sieve desiccant coating captures the water vapor in the air stream and transfers the moisture to where it is needed.

Marywood University: School of Architecture

Scranton, Pennsylvania

Project: Tight humidity control without any active regeneration of desiccant material in a remodeled gymnasium with limited room for ductwork.

Product: Pinnacle, Chilled Beams

Payoff: The design, by engineering firm of Greenman-Pedersen, Inc., called for 42 chilled beams to provide 100% of the cooling for both design studio floors of the renovated building. The design of the entire system was built around the specific inclusion of the SEMCO Pinnacle unit, which offers a wide operating range and can be highly customized for the application. The Pinnacle unit utilizes advanced heat wheel technology to dehumidify and precondition supply ventilation air. The University’s School of Architecture earned LEED Gold certification for the newly-renovated building.

University of Arkansas: Peabody Hall

Fayetteville, Arkansas

Project: Historical Renovation and Efficiency Upgrade with Chilled Beams

Product: Juno - QHC Active Chilled beams and Pinnacle Series

Payoff: Energy efficiency and historic preservation are rarely synonymous.  More often than not, one must be compromised for the sake of the other.  Fortunately, the University of Arkansas found a way around such compromises when it came to the restoration and mechanical renovation of the school’s 100-year-old Peabody Hall. FläktGroup SEMCO’s chilled beams bring 21st century energy efficiency without compromising historic integrity. The dehumidified air from Pinnacle aided in the fight against the building's mold problem, and the non-invasive chilled beams allowed the high tin ceilings to be preserved in all their historic beauty.
