Program Summary
Energy conservation program designed for the healthcare industry
Provides services to participants based on eligibility and customer preferences
Services may include benchmarking, energy assessments, incentive processing, etc.
Cash incentives paid directly to customers Incentive rates are based on type of
measure and services rendered
233
Potential Customers
Medium Healthcare– Small Hospitals (<=300 beds)– Medical office buildings– Large clinics– Assisted living/ nursing homes
Small Healthcare– Small clinics– Doctor’s offices– Physical therapy
244
Program Benefits – Customer
No financial obligation to participate in the program
No deposit required Provides identification of energy conservation
measures (ECMs) Provides cash incentives for ECM
implementation Annual energy and cost savings Minimal time required out of your busy schedule

Services – Healthcare
Facility benchmarking Tier 1: Direct deemed Tier 2: Concise energy assessment
(e.g., small clinics, doctor’s offices, etc.)
Tier 3: Walk-thru energy assessment (e.g., large clinics, medical office buildings, etc.)
Tier 4: Comprehensive energy assessment (e.g., hospitals, assisted living, medical research facilities, etc.)
Tier 5: Measurement & Verification (e.g., hospitals, medical research facilities, etc.)
277
Customized Services
Tier 1: Direct deemed– Customer has already identified ECMs, but needs incentives to proceed– Savings are calculated for standard replacement ECMs using deemed method
Tier 2: Concise energy assessment– Smaller facilities w/lower savings potential– Performed off-site using application and phone interview– Includes standard deemed savings measures only
Tier 3: Walk-thru energy assessment– Small – medium facilities w/reasonable savings potential– Basic study, performed using staff interviews, site visit and collected data– Includes deemed and custom capital expenditure measures
Tier 4: Comprehensive energy assessment – Larger facilities, higher than average EUI, high savings potential– Detailed study, performed using staff interviews, site visit and collected data– Includes capital expenditure and low cost/low payback operational measures
Tier 5: Measurement & Verification (M&V)– Custom capital expenditure measures with significant savings potential– Customer may request assistance in performing M&V

Success Stories
Case 1: Hospital A – ~200 beds; 235,000 ft2; Tier 4 Major ECMs identified – Capital Expenditures
– Replace high pressure sodium parking lot lights with LED lights– Replace T-12 fluorescent lights with high efficiency T-8 lights– Replace older R-11 chiller with new, energy efficient chiller– Replace electric steam generator with natural gas steam generator– Add VFDs to cooling tower fans and heating hot water pumps
Major ECMs identified – Operational – Optimize chiller plant (chilled water temperature reset, chilled water dP reset, reduce
minimum condenser water temperature)– Reset leaving air temperature on all air handling units (AHUs) based on outside air
temperature (OAT) & static pressure (SP)
Potential Savings & Incentives – All Identified ECMs– 30% electricity savings; >$150,000/year energy cost savings; $27,000 in incentives
Potential Savings & Incentives – Only Low Payback ECMs– 7% electricity savings; >$50,000 energy cost savings per year; $8,000 in incentives; <5
month simple payback

Success Stories
Case 2: Assisted Living Facility A – ~300 beds; 240,000 ft2; Tier 4 Major ECMs Identified – Capital Expenditures
– Replace T-12 fluorescent lights with high efficiency T-8 lights– Add lighting occupancy sensors– Upgrade roofing (reflective coating, additional insulation)– Add demand control ventilation (DCV)– Add VFDs and controls to kitchen hoods
Major ECMs Identified – Operational – Optimize chiller plant (chilled water temperature reset, chilled water & heating hot water dP
reset, chiller sequencing)– Optimize other controls (repair sensors, eliminate simultaneous heating & cooling, correct
humidity control, optimize space temperature setpoints, etc.)
