Inpatients Services Building
Floor area: approx. 20,000m2 over 12 levels
Operates 24 x 7
Includes patient wards, operating theatres, isolation rooms, back of house facilities, carpark
Siemens Apogee BMS

Experienced a significant increase in utility cost rates – need to reduce consumption to offset costs
Time poor engineering staff – no way of proactively identifying faults or cost saving opportunities (highly reactive)
Limited transparency of how HVAC systems were performing or where energy was being used

Equipment Fault Detection Module + Software metering deployed on 98 items of HVAC equipment (35 x Air Handling Units, 42 x Fans, 9 x Pumps, 3 x Chillers, 6 x Cooling Tower fans, 3 x Boilers)

Over $60k energy cost savings opportunities identified over the first 8 weeks of operation

Theatre AHU’s and RAF’s operating at full speed 24 x 7 – opportunity for theatre staff turn down when in standby mode using local overrides
Car park fans operating when not required (very low CO levels)
Opportunity to turn down Ward AHU’s during off-peak times
Economy cycle dampers not being fully utilized across Wards & Theatres
Unstable heating and cooling control loops on Theatre AHU’s
Simultaneous heating and cooling in areas that don’t require dehumidification
Heating hot water pump operating for extended periods when associated boiler is off
All condenser water pumps operating for extended periods associated chillers are off

Enabled the Engineering team to gain much greater transparency of energy usage, faults and optimization opportunities
Significant savings already being realised through implementing low-cost BMS fine tuning strategies (no CAPEX)
Opportunity to expand technology to cover 5 additional hospitals in portfolio
