Energy consumption in buildings is responsible for 26% of Australia’s greenhouse gas emissions (CSIRO, 2010). Furthermore the energy consumption associated with
cooling and heating plant in buildings typically accounts for over 50% of the total building energy use (CSIRO, 2010). As a result this project assesses the greenhouse
gas emissions associated with possible air conditioning upgrade alternatives for a multi-storied building 295 Ann Street, Brisbane.

295 Ann Street, Brisbane was constructed in 1973 making the mechanical services plant approximately 38 years old. Due to the age and condition of the air conditioning plant the system is due for replacement.

The aims of the project are to analyse, compare and contrast various air conditioning upgrade alternatives to determine which will provide the greatest greenhouse gas
emissions savings. A BCA2010 reference building will be modeled for each alternative to determine if the existing system or proposed upgrades are compliant
with the Building Code of Australia.

Using the TRACE 700 Load and Energy Analysis Software the upgrade alternatives and reference buildings were modeled. It was identified that significant greenhouse gas emissions savings can be achieved by upgrading the buildings mechanical services. A trigeneration system combined with chilled beams proved to be the most energy efficient.
