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 systems. Results from Greenway's customers show that Cool-n-Save evaporative pre-cooling systems may produce energy cost savings as high as 30 percent, with an average savings of about 26 percent from air conditioning use during peak heat seasons. The company has been developing pre-cool misting technology 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 consumption 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."

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 ambient 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.
Based in Huntington Beach, CA, Greenway Design Group, Inc. has been an innovator of commercial and residential solutions for HVAC systems that conserve energy and equipment since 2005. They sell do-it-yourself residential kits and, in 2008, began marketing commercial systems.
Two Certificate of Merit awards were also presented to finalists in the HMC Green Engineering category: Amonix, Inc., the leading designer and manufacturer of concentrated photovoltaic (CPV) solar power systems, and Fisker Automotive, an American premium electric vehicle manufacturer with a mission to redefine the luxury automobile.
The Harvey Mudd College Green Engineering Award Committee was led by Professor of Engineering, Harris, and included two other professors, two students, one trustee and external industrial members including the prior year’s award winner, M2 Renewables.
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.
