Pymatuning Valley School District

House Bill 264 Energy Conservation Program

pymatuning valley local schools logoThe Brewer-Garrett Company has a strong on-going relationship with the Pymatuning Valley School District. Brewer-Garrett provided cost savings solutions, which included energy efficient heating/ventilating equipment, lighting retrofits, vending machines, and building automation system upgrades.

In the latest phase of House Bill 264 Energy Conservation Projects, significant mechanical upgrades were made throughout the District.

Another very successful strategy for limiting energy use is CO2 control or demand ventilation. One of the largest uses for energy in a building is heating or cooling ventilation air. Appropriate amounts of fresh are necessary whenever a space is occupied. Demand control limits the amount of outside air introduced and thus conditioned, when no people are occupying the space. Not only does this cut down on energy usage, but it also provides improved building comfort and control in the heating and cooling seasons.

Brewer-Garrett utilized this strategy in the following areas: High School Gym, Performing Arts Center, Elementary Gym, old Elementary Cafeteria, and the new Elementary Cafeteria, also known as the “Sunshine Room”.

All three Pymatuning Valley school buildings are equipped with a Novar Trend control system. The Brewer-Garrett Company opened the system and performed programming, which enabled Pymatuning staff the ability to input schedules and energy saving strategies.

Brewer-Garrett installed individual meters in each building for both gas and electrical use. While these meters will not be used for billing purposes, as they will be located behind the utility meters, Pymatuning Valley schools will be able to use them to gain an understanding of how each building is operating. This will enable the district to monitor annual usage, and track each buildings individual performance.

Standard Lighting Retrofits

Linear Fluorescent Retrofit - During the course of the lighting audit, 32w T8 fluorescent lamps with 1st generation electronic ballasts were found throughout the facilities. By changing from 1st generation electronic ballasts and 32w lamps to 25w lamps with the most efficient electronic ballasts, up to 20% energy savings is realized. The older model 8’ T12 fixtures in the Schools were retrofit with a new reflector made to accept the same 4’ T8 lamps installed throughout all of the buildings. This drastically reduced the need to purchase and store 8’ lamps.

High-Bay Fluorescent Technology - Special consideration was given to HID luminaires within the various areas at Pymatuning Valley School District. The Brewer-Garrett Company recommended a straightforward one-for-one replacement of the existing 400-watt metal halides with a 4 lamp T5HO high bay fixture. These new fixtures utilize fluorescent technology that maintains light levels and enhances uniformity. With fluorescent lamps, lights can be switched off to maximize energy savings. When switched on the lights ignite immediately, so an aggressive policy was implemented to minimize unnecessary operational times. Additionally, the luminaires have 4 lamps each. If one lamp extinguishes, 3 lamps are still working, decreasing the immediate need for maintenance to correct the problem. To meet Jarod’s Law lighting requirements throughout the school gymnasiums, each retrofit has been designed to comply with this new requirement.

Vending Machines - Vending machines throughout the Schools are controlled using a load-managing device. This device shuts the machines down when the area is unoccupied, and turns the lights and compressor on when someone approaches the machine. This results in saving energy, while maintaining appropriate temperature of the delivered product.
