Innovation in Coolness Celebrated HMC GREEN ENGINEERING AWARD GOES TO GREENWAY DESIGN GROUP
For the fourth year, Harvey Mudd College awarded its Green Engineering Award at the Annual Orange County High-Tech Innovation Awards. Energy firm Greenway Design Group, Inc. was recognized for its energy-saving evaporative pre-cool mist- ing technology designed for commercial and residential central air conditioning systems. Greenway Design Group, Inc. is the innovator of “pre-cool” solutions, marketed under the trademark “Cool-n-Save,” that reduce the cost of operating conventional air conditioning sys- tems by as much as 30 percent. Greenway Independent studies, field tests and Greenway’s residential and commercial custom- ers show that Cool-n-Save evaporative pre-cooling systems may produce energy cost savings as much as 30 percent, with an average savings of about 26 percent from air conditioning use during peak heat seasons. Based in Huntington Beach, Calif., Greenway Design Group, Inc. has been an innovator of com- mercial and residential solutions for HVAC systems that con- serve energy and equipment since 2005. “We are grateful to have received this tremendous honor for
our work of the last five years,” says Darius Jakubik, Greenway’s senior vice president. “Cool-n-Save could be the answer to a country in search of a way to significantly reduce energy con- sumption and cut carbon output. We developed Cool-n-Save to be cost-effective and practical. Many of our customers have seen enough savings to make up the cost of their investment in less than 12 months.” “Greenway has led the way in designing technology for energy saving air conditioning systems,” added David Money
TEACHING AND LEARNING BUILDING On the Move
Several moves are occurring this summer to prepare for the up- coming demolition of Thomas-Garrett Hall. Computing Information Services staff moved to the fifth floor of Sprague Center. Spaces in Parsons basement vacated by CIS will be occupied by those in Advancement who had offices in Thomas-Garrett: Communications, Reunion Programming, Phonathon and Annual Fund. Academic Ex- cellence and the Writing Center, which were also located in Thomas- Garrett, have also been temporarily located to Parsons basement offices before their final move to the new teaching and learning building, estimated to be completed by spring 2013.
Harris, professor of engineering, who presented the award on behalf of the College and its engineering department. “I grew up in the Mojave Desert, where evaporative cooling was the most cost-effective way to keep a building comfortable in the dry sum- mers. It is exciting to see the technology applied to improve the efficiency of air conditioning by about 25 percent even in normal climates. As air conditioning is one of the major consumers of energy in the United States, this technology will make a huge impact.”
The Cool-n-Save pre-cool system raises a “pre-cool shield”
of treated water mist into the air around an HVAC unit. Flash evaporation causes the mist to evaporate almost instantly. The result is an adiabatic boundary, a shield that literally insulates the HVAC from excess heat. Ambient air temperature around the unit drops by as much as 30°F. That means that if the am- bient air temperature is 98°F, Cool-n-Save will reduce it to 68°F. The air then acts on the fins and increases heat exchange efficiency. Two Certificate of Merit awards were also presented to final- ists in the HMC Green Engineering category: Amonix, Inc., the leading designer and manufacturer of concentrated photovoltaic (CPV) solar power systems, and Fisker Automotive, an Ameri- can premium electric vehicle manufacturer with a mission to redefine the luxury automobile. The Green Engineering Award, established in 2008, was
sponsored this year by Mavenlink LLC. Their CEO Ray Grainger ’88, is also a trustee of Harvey Mudd College and chairman of the Finance and Budget Committee.
