After initially updating the exterior of the facility, Peterbilt wanted to move forward with the interior knowing the benefits based on experience. Rocknoll Energy provided further evidence to move forward based on the audit and analysis with a great ROI. In addition, we provided specific LED suggestions based on types of work areas, heights and function of space. The project resulted in a cleaner look for the lobby and office space but, most importantly, brighter bays for their maintenance and repair employees to perform their job better. Rocknoll Energy filed for the Duke rebate; the result was a check written directly to Peterbilt in the exact amount expected. Win, Win!
