Energy reduction at the Fort Hood Warrior Way convenience store was accomplished through several innovative strategies including energy audits, the installation of energy conservation measures, and rebate management with a single national vendor contract. Among extensive energy savings, this strategy also substantially reduced project costs, project management, and costly negotiations among multiple vendors. Energy improvements included:
- An extensive building management system
- The Wattstopper lighting control system
- A 24-channel power monitoring system
- A HVAC control thermostat with economizer control
- Walk-in temperature sensors, perimeter, and walk-in door position sensors
- Electronically commutated motors replaced the shaded pole motors for evaporator coils in walk-in coolers and freezers
- Occupancy sensors to control the product lights which illuminated only when customers are in the product area
- LED light bars replaced T12 fluorescent product lights
- Reflectors were upgraded from 50% reflectance to 94% reflectance
- Bulbs were changed and reduced from 4x32 W bulbs to 2x28 W bulbs with an extended 50,000-hour life
- Ballasts were replaced with high efficiency ballasts
- Storage, restrooms, and break area were changed to occupancy sensors.
As a result of the improvements, Fort Hood's Warrior Way energy use was decreased by 44% compared to same month average use from previous years.
