The opening of Stage 1 of Echuca Regional Health’s redevelopment was a major milestone in the hospital’s 130-year history of delivering
  care to communities along the Murray River, bordering NSW & Victoria. 
  The public hospital has been providing health services to the Murray
  region since 1882 when the first patient was admitted; however in
  recent years the facilities had become dated and inadequate for the
  current needs. In 2010 1,600 people rallied in the hospital grounds
  to highlight the desperate need for a new public hospital. This led
  to State and Federal Government funding of $65.6 million to redevelop
and expand the hospital.

  Project Manager Mark Hooper said
  the redevelopment involved rebuilding
  the acute care services and emergency
  department as well as the front entrance,
  pharmacy and health information services.
  “The project allowed us to improve patient comfort, increase
  the building’s energy efficiencies and lift the hospital’s capacity
by 66%, with bed numbers rising from 68 to 113,” he said.
Construction for Stage 1 began in 2013 and was completed in June
  2014. Patient rooms now include an en-suite, computer and electronic
  call system for improved communication within the hospital.
  Mark said the HVAC system had been designed to create greater patient
  comfort by allowing them to control the environment in their room.
Brett Seeney, an Associate with WSP Consultants, Melbourne, worked
  closely with Mark to design the HVAC system. The innovative design
  earned WSP the AIRAH Award for ‘Excellence in Innovation’, 2014.
 “We wanted to create a 100% fresh air system with maximum energy
  efficiency. To help achieve this Brett’s HVAC system design started
  with Rickard electronic Variable Air Volume (VAV) diffusers. The air
  conditioning system and energy recovery units were then built around
  them. The VAV diffusers help create a well ventilated indoor environment
  that maintains a consistent and comfortable temperature,” Mark said.
 “Stage 1 of the project has 280 Rickard VAV diffusers connected
  to variable speed AHUs supplying air via insulated solid ducting.
  There is no flexible duct and the system uses static regain duct-work
  which ensures a constant amount of pressure to each diffuser.
  The diffuser aperture opens and closes depending on the volume
  of hot or cold air required in the room and the resulting change in
  pressure in the ductwork signals the air conditioning system to speed
  up or slow down as required.”  
Each room has a VAV diffuser supply and return, with two supplies fitted
  in the larger rooms. “We were mindful that patients need to rest while in hospital and as a result the system pressure was reduced from
  50Pa to 35Pa to remove all noise from the diffusers,” he said.
Mark said further energy efficiencies were gained by having triple
  glazed windows in the bedrooms and a rooftop solar field to provide
  energy for the chilled water system. The overall result is designed
  to achieve one of the lowest energy footprints per square metre
  of any hospital in Victoria.  
The focus is now on Stage 2 which will include an expanded
  emergency department, a six-bed short medical assessment
  and procedure unit and upgrades to maternity services.
  It will also see construction of the pharmacy, a spiritual space,
  and an aesthetic landscaping design. The project is due to be
  complete in September 2015.
