Project Case Studies <br />Poway Unified School District <br />3776 Annual Energy Savings <br />PROJECT DESCRIPTION <br />This project was installed for the Poway Unified School District in Poway, California from 2014 - 2016. ERC worked <br />as a subcontractor for Bamham Construction and together the companies won a bid RFP that was valued at $1.5M. <br />The project featured funding from California Prop 39, as well as significant rebates from SDG&E. <br />SCOPE OF WORK <br />Project Images <br />✓ Designed and installed new LED lighting for two elementary and two high schools in the PUSD. <br />✓ The retrofit solution included the replacement of all HID and Fluorescent technology with LED. <br />✓ CREE LED troffer fixtures, CREE Bi -Level wall packs, LED Can retrofit kits, LED Type.A Tubes with new <br />ballasts, and CREE Area Lights. <br />✓ Installation of low voltage 0-10V dimming controls in all classrooms and offices. <br />✓ Overall reduction of 37% in energy use. <br />✓ Overall project cost= $1.6M. <br />PROJECT CHALLENGES & SOLUTIONS <br />✓ The District stated it was important that the new dimming controls technology be easy to use by the school <br />room teachers and the school staff. <br />✓ Our Team designed a Lighting Controls Solution that included occupancy sensors, controls, and dimming <br />technology that were easy to use by the staff. ERC offered a commissioning process which featured both <br />training for the staff as well as system setup in each room. <br />✓ Low Voltage 0-10V dimming controls were designed to ensure that dimming circuit #1 controlled the two <br />fixtures directly in front of the classroom projector screen, whereas the balance of the fixtures in the <br />classroom were controlled by dimming circuit #2. <br />E@dERGY REfROFFT Ca <br />11 <br />
