Cenergistic Approach 2

Efforts to Date Six dedicated Energy Specialists hired in May 2015, including 4 former PCSB employees Energy Specialists have completed thousands of site visits to facilities county wide Daily review of the districts 140+ building automation (BAS) schedules Comprehensive training and analysis of billing history to identify conservation opportunities Over 350 FTE days on site by Cenergistic engineers and consultants Database and billing analysis for 1,305 utility accounts and 1,624 meters 3

A Day in the Life of an Energy Specialist Continual building presence with on-site audits Train one-on-one with Cenergistic staff Visit with Cenergistic engineers and consultants Program energy management system (EMS) and work with maintenance team Match conditioning times to occupied times Work cooperatively with maintenance in field Plan strategically for extended breaks Communicate to teachers and staff Promote an “energy conservation culture ” 4
