Winning MultiStack project showcases a successful approach to improving energy efficiency in existing buildings
Danfoss, a manufacturer of high-efficiency electronic and mechanical components and controls for air-conditioning, heating, refrigeration and motion systems, recognized MultiStack LLC of Sparta, Wis., as the winner of the second annual “EnVisioneer of the Year” award competition for its success in implementing energy-efficient practices.
The award was presented on Oct. 5 in Washington, D.C., following the annual Alliance to Save Energy’s Stars of Energy Efficiency gala.
MultiStack, a manufacturer of high-efficiency modular chillers for commercial, industrial and government applications, installed two MultiStack chillers at Valley High School in Las Vegas. The installation included eight Danfoss Turbocor compressors, four Danfoss VLT variable frequency drives and the MultiStack FlexSys controller, which incorporates Danfoss Turbocor software.
By switching to the magnetic levitation-powered chillers and a central plant control system, school administrators hoped to reduce energy use at the 45-year-old building by 50%. In fact, the school exceeded its goal by 20%.
“We are excited to recognize MultiStack’s winning approach to energy efficiency,” said Danfoss North America President John Galyen. “This application is particularly interesting because it demonstrates the impressive savings that can be achieved in existing buildings by investing in and applying energy-efficient technology available on the market today. It’s proof that upgrades that can be made right now will have a big impact on the future of the building and the environment.”
The award competition was launched in 2010 by Danfoss to recognize end users, building owners and original equipment manufacturers that exemplify the Danfoss EnVisioneering core values and have used Danfoss products to realize significant energy and/or environment savings.
In recognition of the energy-efficiency achievements of MultiStack, Danfoss made a financial contribution in the winner’s honor to Rebuilding Together.
