The scope of the services for the lighting retrofits started with a comprehensive energy analysis of each facility’s lighting
system, existing light fixtures, existing lighting controls (if any), historical energy usage, current energy costs and
operational lighting requirements. From this analysis, Bluestone Construction provided a design for the retrofit and
control of the light fixtures in the facility, estimated construction costs for fixture replacement and calculated the
anticipated energy cost savings. The primary component of the retrofit involved replacing HID and HPS fixtures with
energy efficient T-12 fluorescent fixtures controlled by a motion sensor on each fixture. The energy cost savings included
both the direct costs for operation of the light fixtures themselves as well as the indirect costs for reduction in cooling loads
for the facility. Bluestone also investigated government and utility company incentives for each location.
A return on investment (ROI) was developed for each facility using the projected capital improvement investment for the
lighting retrofit and the projected energy cost savings. The ROI ranged from 17% to 111%, with an overall average of
Once each project was approved, Bluestone managed the purchase of the lighting fixtures and their replacement within the
facility. Bluestone coordinated the work with operations management at the facility so that the continued production
operations was not impacted.
