St Andrews Hospital

Energy Usage Energy Usage
With the development of the site services masterplan by System Solutions Engineering, the capacity and age of the existing medical breathing air system was assessed as inadequate. The need for an upgrade to meet future capacity and quality requirements while maintaining a reliable and energy-efficient medical breathing air supply was quickly recognised as a site priority.

The original equipment consisted of two individual air compressor systems, one serving the theatre wing and the other serving the central wing. Both plants were identified as beyond their economic life cycle and both had limited parts availability. In addition, the energy consumption of both plants was deemed extreme. Seeing the new Clinical Wing was in the design stages, the ability to serve this new load was considered within the overall concept developed by SSE. Now the hospital has a main ring serving the site including the new Clinical Wing with a total of four scroll compressor packages each containing three compressors.

New air filtration, air flow and air quality monitoring has been built in for each set of compressors and all compressors are controlled by an hours’ equalisation algorithm built into the compressor packages. The site currently operates with only one compressor package online at any time and uses a fraction of the power to produce the current air demand. The entire network and all air compressors are monitored by the BMS, with any warnings being transmitted to maintenance via the BMS. The new system is ready to serve the new clinical building and the existing hospital with clean reliable medical air well into the future.

Marquee Project/

CSIRO Glasshouse

The aim of this project was to provide a glasshouse for CSIRO’s agricultural research on the interactions of plant pathogens and more specifically grapevine pathology. The structure was designed for and achieved PC2 and QC2 certification. One key building design feature is the flexibility to cordon off areas within the glasshouse for particular classifications of work without disrupting or cross contaminating adjacent areas.

General Information:

  • 216sqm floor area with capability to be divided into 4 separate quadrants with an ante room at either end.

Relevant Standards:

  • AS/NZS 2243.3:2010, Section 7.3 Requirements for Plant PC2 Facilities
  • DAFF QAP Criteria 6.1 Closed Quarantine Facilities for Medium Risk Nursery Stock
  • Temperature controlled and monitored environment.

While the glasshouse itself and project was delivered through a design and construct model, the engineering services required a more detailed approach and so a typical design-bid-build strategy was integrated into the design and construction framework. This approach ensured the detail and quality of finish required for PC2 and QC2 certification was successfully achieved. Engineering containment facilities for pathogen control is not new to SSE. Earlier in 2015, we completed the only PC3 compliant laboratory in South Australia, designed with standards fit for the World Health Organisation.

Sunfresh Salads

The chilled water temperature is monitored to 0.01 degree accuracy to give ultimate temperature control and system reaction. 0.01 degree accuracy
System Solutions Engineering were called to Sunfresh Salads to resolve issues associated with repetitive failures of their pasta chiller heat exchanger and refrigeration failures. Following an assessment of the issues, previous experience indicated that the current method of chilling water for product cooling could never be reliable in the long term, because at the time, temperature control needed to be achieved through the refrigeration system’s pressure control.

In addition to this, the client advised that they planned to purchase a new 1400kg pasta cooker and any resolution to the existing problems would have to take into account the additional capacity.

In response to this challenge, SSE proposed that the client use existing refrigeration infrastructure to build an integrated package of refrigeration, controls and pumping. Together, this would create a circulating glycol system which would be utilised to provide cooling for a submerged coiltype chilled water heat exchanger. This resolution provided a new degree of reliability with increased cooling capacity and production potential. The new glycol system is expandable with the opportunity of serving a number of product chilling applications throughout the factory.

  • Dramatic decrease in energy consumption
  • Base building electricity down by 45%
  • Gas is now down by 35% from its peak
  • Comfort levels greatly improved
  • Building now capable of coping with Adelaide’s most extreme conditions
  • Staggering improvement in the NABERS rating with a rise from 2.96 to 4.72 stars in 2.5 years

System Solutions Engineering designed and project-managed the refurbishment of the mechanical and thermal plant including a BMS upgrade between July 2011 and January 2012.

The building’s initial NABERS rating was below 3.0 (approximately 2.96) prior to the upgrade works taking place. As soon as the new plant was commissioned, the reduction in electrical energy was apparent. As the building’s data was collected and analysed by System Solutions Engineering, tuning strategies were introduced, continually analysed and refined over a period of two years, until the building comfort levels were optimised and the consumption of electricity and gas was honed to its optimal levels.

99 Gawler Place

Electricity Usage Electricity Usage Gas Usage Gas Usage
System Solutions Engineering has been involved at 99 Gawler Place since 2010. During this period, the base-building electrical usage has been reduced by over 54%, from 1,164,958 kWh p.a. to 530,556 kWh p.a. and steady improvements have been made to natural gas usage, resulting in an overall increase of approximately 0.84 NABERS stars, from NABERS 3.5 stars to 4.34 stars (unofficial).

While energy improvements have resulted, the greatest gains have been with internal conditions – which have been significantly improved through modifications to the existing mechanical plant and the installation of new automatic controls, providing more stable conditions within the tenancy spaces. Additional return air pathways have also been added to reduce drafts within the occupied spaces – which was previously an unresolved problem within the building.


  • SSE introduced a total of 12 ESD strategies
  • The building achieved NABERS 4.34 in May 2014
  • Building now targeting NABERS 4.5

System Solutions Engineering has worked with SA Health for over 14 years in the sustainment of existing facilities and in many cases has assisted with the briefing of many of the Major Projects in both Metro and SA Country Health.


  • Reinitiating economy cycle systems
  • Heat recovery from exhaust air paths
  • Major site-wide proliferation and replacement of BMS controls
  • Use of high efficiency chillers and boilers
  • Reduction in the use of High Temperature Heating Hot Water
  • Use of variable speed drive technology for pumping and air handling systems
  • Halving the outside air to theatres combined with heat recovery
  • Use of the Shaw Method of Air Conditioning to control humidity
  • Installation of a solar hot water system for the whole of the site (60% Contribution)
  • Energy efficient lighting systems to all areas of the redevelopment
  • Introduction of 3C coolers (50% water saving over traditional cooling towers)
  • Collection of all rainwater from new south wing for use in toilets
  • Collection of waste water from the reverse osmosis process for use in toilets
  • Generally optimising the efficiency of all energy/water appliances

Prior to the Flinders Medical Centre’s Major Project being conceived, in 2006/7, SSE was asked by SA Health to develop a brief for the overall sustainment of the engineering services across the site, which was expected to be as much as 25% of the overall $160M notional budget.

SSE audited the engineering infrastructure, analysed the operation of the plant, serviceability, compliance, OH&S issues and energy performance and then prepared a brief to consultants tendering for the overall redevelopment. The briefing included a sustainment plan for all engineering disciplines as well as an overall strategy for energy improvements in line with SA Health and SA Government targets.

SSE were subsequently asked by consulting firm Aecom in 2007/8 to collaborate with them for the delivery of the engineering designs within the overall redevelopment. SSE participated in Stage 1, being the main infrastructure upgrading works of some $30M and were directly responsible for:

  • Conversion of the High Temperature Heating Hot Water to Medium Temperature Heating Hot Water;
  • Steam Rationalisation & improved reticulation;
  • Upgrade of eight (8) passenger lifts;
  • Site-wide BMS Upgrade, completely replacing the older I-Net7 BMS and legacy pneumatic systems.

SSE also assisted Aecom with peer reviews of their completed designs prior to tendering to specialist trades. Since completing our initial works, SSE has continued to provide a reviewing and supporting role to the Flinders Medical Centre in the areas of sustainment and energy performance.

The Northern Festival Centre, Port Pirie

The new high-efficiency chiller is fitted with adiabatic cooling pads so that even at high ambient temperatures of over 40 degrees C, the chiller sees an air temperature of no more than 29 degrees. This greatly reduces the maximum power demand and improves the available capacity during hot weather. Energy Usage
Country Arts SA approached System Solutions Engineering to assist them with the development of concepts and budgets for the upgrade of air conditioning plant including improvements to the Northern Festival Centre’s ballroom which was currently air conditioned using evaporative coolers and gas air heating.

SSE developed an approach which allowed the centre to remain fully operational for much of the construction period. The solution enabled the expansion of mechanical plant designed to provide air conditioning to the ballroom, as well as refurbishment of the existing mechanical plant... all within budget.

The features of the plant which provide energy efficiency and performance include adiabatic cooling on the chiller, high efficiency condensing boilers which also provide domestic hot water via a heat exchanger and new pumps, economy cycles and new BMS controls with the latest energy efficiency strategies including time scheduling for functions.
