Chesser House Sustainability Project Sustainability Project - PowerPoint PPT Presentation

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 ). Images sourced from private collection

Methodology 1 Completing the study involved 4 key stages: • Data collection and site familiarisation phase � Drawings � Technical data � Metering data • Detailed research phase � Focusing on ‘innovative’ concepts � Focusing on ‘innovative’ concepts • Modeling and calculation phase • Reporting phase � Comparative results included

Methodology 2 Each concept was allocated into 1 of 3 categories: Business As Usual: Sustainable Practice: Stretch Objectives:
