This project is a design-build lighting retrofit for California State University, Sacramento’s campus library. Mark III’s scope included lighting removal and retrofit of all five (5) floors within the campus library. The electrical team removed 50% of the lighting and retrofitted the remaining fixtures. This will achieve a reduction in lighting power by approximately 70% to ensure the facility is in compliance with state mandated energy efficiency standards while maintaining the previous lighting levels. Mark III’s virtual construction team created layout drawings and respective lighting kits organized by floor and delivered to site for installation.
