Chesser House Sustainability Project Sustainability Project

Presenter: Peter Stokoe System Solutions Engineering

Project Overview 1

Aims:

• Provide a report which assesses and compares various

energy and greenhouse gas saving techniques for commercial office buildings.

• Provide recommendations based on comparison for

possible upgrades which would achieve the desired possible upgrades which would achieve the desired NABERS Energy (base building) rating at Chesser House.

• Provide comments on the suitability of each concept

to other commercial office buildings, along with estimated reductions in energy consumption where possible.

Project Overview 2

Chesser House:

• 12 Storey commercial office

building, located in Adelaide’s CBD.

• Constructed in the late 1980s.
• Recently completed several

energy efficiency upgrades, with further upgrades planned.

• Estimated to currently be

achieving a NABERS energy (Base Building) rating of 4 stars. (At time of study, estimate was 3.5 stars).

Key Findings 4

Estimated savings: Whole Building: Total Reduction in Electricity Consumption: 168,110kWhr Total Reduction in Greenhouse Gas Emissions: 125.66t Base Building: Total Reduction in Electricity Consumption: 122,410kWhr Total Reduction in Electricity Consumption: 122,410kWhr Total Reduction in Greenhouse Gas Emissions: 84.01t Percentage Electricity Consumption: 12.5% Percentage Greenhouse Gas Emissions: 8.6%

Increase in NABERS Energy (base building) Rating from 3.5 to 4 stars (at time of study)

Conclusion

Achievements:

• Completion of the project gave Chesser Properties an

insight into potential ways to achieve their desired NABERS energy rating.

• A document has now been produced which can

potentially assist others in the industry who wish to potentially assist others in the industry who wish to increase their NABERS energy rating.
