Jaeger 8

Jaeger 8 was designed to achieve a 5-star energy rating. The building is well insulated, has high thermal mass and windows and sun screening is designed to provide maximum daylight while minimising direct penetration of sunlight during summer months to keep out excess heat. The building form, fabric and structure assist with the passive mechanical HVAC system.

The building is located next to the Old Hospital Building, part of the original Canberra Community Hospital. There are a number of highly rated and exceptional trees adjacent to the site. These are predominately Conifer and Eucalypt Species, including a Weston planting from the 1930s. Brickwork from the original building was recovered and reused in the facade of the new building, thereby minimising resource waste and retaining a prominent reminder of the history and heritage values of the site.

Jaeger 8 forms part of the 'Jaeger Precinct' which is a conglomeration of buildings and is home to the Research School of Earth Sciences (RSES).

Building features

Key features include:

  • Signature building
  • EDS initiatives
  • 2276.46m2 gross floor area.

Green features include:

  • Kingspan roof
  • Kingspan walls
  • Double glazed windows
  • Mechanical heating & cooling range 20C - 26C
  • Rainwater tanks for cooling, toilet flushing & landscape watering.

Outcomes

  • The innovative cooling system utilises the stored rain water and the basement rock storage to assist with providing cooled air to the upper levels via thermal stacks.
  • Individual temperature control within each office space.
  • Partially exposed concrete ceilings in office areas to assist with radiant cooling and heating.
  • Provision of ceiling fans in each office space.
  • Natural ventilation through operable windows to all offices. Some windows controlled via actuators to allow night purging of the building.
  • Double glazed windows.
  • Rain Water tank for building cooling and landscape irrigation.

Building design

The new Jaeger 8 Building consists of 3 levels and basement. It is the new main entry and address for all the current buildings and facilities for the RSES. 

Jaeger 8 provides teaching requirements for 2nd and 3rd year students relocated from the Department of Earth Marine Sciences Building (DEMS), D A Brown Building (47) located on Linnaeus Way.

The new building provides office space for executive offices, academic offices, reception, PhD student rooms, honours, masters, specialist storage areas, conference facilities, two teaching spaces and other meeting and amenity spaces.

Jaeger 8 provides the school with an identifiable front entrance, much needed facilities and space allocation allowing the school to work more efficiently with 2nd and 3rd year PhD and Masters students.

Constant indoor temperatures are not to be maintained. Rather, some variation within an expected range will be accepted. The initial expected range is 20°C - 26°C. The building has a central built up air handling unit (AHU) located in the basement.

When the building is cooled for heated by the AHU, return air is drawn from the occupied floors by the AHU and is then cooled or heated and delivered to a basement plenum. Supply air is taken from the plenum, by other fans, and delive4red to ceiling space plenums on each of the three occupied floors, via risers. Each riser delivers air to only one floor. Supply fans operate to maintain a particular pressure in the plenum that they serve.

Heating/cooling air is delivered into rooms from the ceiling plenums though variable volume air outlets. Plenum pressure drives this airflow. Ventilation air is separately delivered to each room (at the supply air register or diffuser). It is a mixture of outdoor air and GPAC treated return air - compliant with AS1668.2:1991. Return air is filtered before entering the GPAC. Air leaving the GPAC and outdoor air is filtered.

Daytime cooling effect is delivered to the ANU cooling coil by water stored in a tank. The tank also serves irrigation and toilet flush. The water is cooled at night by the AHU by having outside air pass though it.

On some occasions, when outdoor night temperature is high, the water in the tank is cooled by a water chiller - with the AHU acting as a dry condensing water cooler. Heating effect is delivered to the AHY heating coil by a condensing boiler located in the basement.
