Do It In The Dark Kent State

kent state logo"Do it in the Dark" is a two week energy conservation competition hosted by Residence Services at Kent State University in Kent, Ohio.

Each fall semester Residence Services hosts the annual “Do it in the Dark” energy reduction competition, putting residence hall vs. residence hall in a battle to reduce electricity over a two week period of time. Students step up their efforts to reduce electricity usage and help their hall win $200 toward Hall Council funds!

Cleveland State University – Science and Science Research Buildings

Fume Hood Renovations

cleveland state university logoUnder the House Bill 7 legislation, the Brewer-Garrett team was selected to renovate and modernize laboratories and laboratory hoods in Cleveland State University's Science and Science Research Buildings to meet anticipated laboratory requirements that included 87 laboratories and 121fume hoods using a "Labs 21" approach [Labs For the 21st Century, or Labs 21, is a voluntary partnership co-sponsored by the U.S. Environmental Protection Agency (EPA), the U.S. Department of Energy (DOE) and the International Institute for Sustainable Laboratories (I2SL)]. Cleveland State University also included VAV fume hood controls, and a facility air monitoring system that would interface with the existing building automation system. CSU was also interested in pursuing other alternatives that included looking at replacing air handling units, exhaust fans, pneumatic controls, and dual duct boxes in order to improve student and faculty safety and comfort.

In order to evaluate approaches to reducing energy consumption in the laboratories and maximize the magnitude of capital improvements for the University, the Brewer-Garrett Team utilized an energy simulation program to model existing building conditions, then modeled two proposed approaches, and then compared these approaches against existing conditions. To calculate proposed savings and cleveland state labsmaximize total impact, two independent and separate analyses were performed that back-checked energy savings to within 3 % of each other. With extensive technical analysis complete, The Brewer-Garrett team developed two distinct approaches to reduce energy in laboratories while upgrading laboratory facilities. Option I included VAV fume hood control, retrofitting existing air handling units, installing dual duct VAV boxes, new DDC controls, variable Option II included low-flow, constant volume fume hoods, heat recover loop, refurbishing existing dual duct boxes, and retrofitting existing air handling units. Both options included new base cabinets and fume hoods, expanded automation to all air-handling units and exhaust fans, retrocommissioning for existing chillers, air handling units, pumps, hot water systems, exhaust fans, water conservation and lighting retrofits. Finally, six alternates for new exhaust fans, VAV boxes and new dual duct air handling systems, were included for program expansion should the University choose.

Ashland University

ashland universityThe Brewer-Garrett Company was selected by the Ashland University to design and install energy efficiency and capital improvement projects that will achieve the significant reductions in energy consumption and operational costs.

Ashland University’s performance contract scope includes interior lighting retrofit, heat pump conversion, replacement of lower level water loop piping, replacement of water loop piping risers and the addition of a supplemental solar array. These energy conservation measures assist the University in achieving energy reduction goals, restore the quality and sustainability of the University’s asset base, and address safety and comfort issues of the University community.

Interior lighting retrofits include replacement of current 32W T8 fluorescent lamps with energy efficient 25W T8 lamps and new ballasts. This solution reduces energy consumption while maintaining the existing light levels and also provides significant operational value by standardizing lamp and ballast type.

The heat pump conversion involves the replacement of water-source cooling units with new “water furnace” heat pumps, including the duct and piping connections. Additionally two 1,500 mBH gas-fired boilers and associated gas and water piping were included in this installation. This conversion also includes installation of new exterior gas lines from the existing campus loop to the boiler system.

In addition this program includes replacing two sets of main distribution risers to distribute water to the heat pumps, and replacing the water distribution piping in the lower level of the facility. This will ensure that the system is able to deliver the necessary water flow to the new heat pumps for many years.

Ashland University had a great opportunity to take advantage of solar energy technology and the Solar Renewable Energy Credit (SREC) that were used to fund the installation of a solar energy system. This program included the installation of a 10KW photovoltaic system, on the south-facing side of the lower roof of the Library. The system capabilities include metering on site, as well as online tracking through Fat Spaniel, a website designed to highlight the performance of green technology. This proactive approach to alternative energy provides A
