Project Background
Marlington Local Schools are interested in upgrading the lighting, building envelope and adding cooling to (3) elementary schools. The intent of this deliverable is to give the district pricing on different cooling/heating options at each building, to provide pros and cons of each and provide pricing on building upgrades such as LED Lighting, Roof, Windows and Door’s
