The Solutions
As a school district located in the mountains of rural West Virginia, “traditional” means that funding for renovations are limited. CMTA was thrilled to partner with Grant County Schools to implement a guaranteed energy savings contract to upgrade all four of their schools. For a successful project at Grant County, CMTA took a meticulous project approach. Real project savings, rather than stipulated, were critical to help the district’s constricted budget. CMTA’s drive to reach national energy goals pushed the team to reach Zero Energy at Petersburg Elementary. The building was not Zero Energy ready prior to this project. The elementary facility had a unique opportunity to have a large solar array installed that would be fully funded by energy savings. A thoroughly commissioned HVAC control system and LED lighting upgrades were key factors in driving the energy usage of the building down and achieve the goal of Zero Energy.
CMTA implemented the largest net-metered solar array in the state of West Virginia at Grant County Schools’ Petersburg Elementary. This elementary school has a utility rate structure that dramatically impacts the payback period of a solar installation. For this reason, Grant County had the perfect opportunity to install a sizable solar array to generate energy savings and fund the district project. Excess savings generated by the shortened solar array payback period was allocated towards upgrading the district’s HVAC control system.
A new district HVAC digital control system was designed to wring out wasted energy being consumed when schools were unoccupied. The new web-based HVAC control systems were connected to create better building monitoring and diagnostics. CMTA also improved existing lighting fixtures, upgrading the entire district to LED technology. Other improvements included installing an HVAC system at the main high school gymnasium. Plumbing fixtures were upgraded to minimize water consumption costs. CMTA also identified over $30,000 in utility overcharges through a complete utility bill audit before the project kicked off. Grant County will now save $30,000 on an annual basis due to the billing error being caught. Grant County Schools received over $115,000 in utility credits for overcharges over the past three years.
