ENGG941 Sustainability for Engineers, Scientists and Professionals Assignment 2

Analysis of Building Sustainability

Deadline for submitting Assignment 2 due at 4 pm Friday Week 13 (1st June) to EIS Central [Penalty for late submission 5% of total assignment mark per day late]

Australia generates about 1.5% of global greenhouse gas emissions. However, on a per capita basis, Australia is one of the world’s largest polluters. It is reported that 23% of Australia’s total greenhouse gas emissions are a result of energy demand in buildings. Since 2002, parts of Australia have been subject to mandatory water restrictions in response to drought conditions. Therefore, the rapid enhancement of water and energy performance of the building sector can significantly add to the environmental, social and economic benefits across the country, timely reduce global energy use and promote environmental sustainability. Appropriate analysis of building water performance, energy performance, and indoor thermal comfort, are among the key steps towards the sustainability of the built environment.

Assignment task

This is a group assignment and each group should have 4 members. The assignment is designed to use Building Sustainability Index (BASIX) online tool to analyse building water and energy performance and indoor thermal comfort by using different technical options to reduce water and energy consumption and improve indoor thermal performance, and optimise the design of building such as the landscape, water resource system, hot water system, and heating, ventilation, and air- conditioning (HVAC) system. BASIX was developed to facilitate the implementation of minimum sustainability targets for all new houses, home units and renovations across New South Wales. As shown in Figure 1, this assignment will consist of three key subtasks with different levels of technical details, knowledge and skills. In this assignment, your group will need to improve the water performance of the case study building provided to BASIX score of over 40%, 50% and 60% respectively, improve the thermal comfort of the case study building to BASIX score of PASS; and improve the energy performance of the case study building to BASIX score of over 50%, 65% and 80%, respectively.

Figure 1: Specific tasks required in this assignment.

Sub-Task 1: Building water performance. In this sub-task, your group needs to assess the water performance of the case study building provided, analyse the potential solutions to improve the water performance of the case study building by taking into consideration of the economic investment. This will consist of four steps: 1) calculate the BASIX score of waterof the original case study building, and analyse the reasons why the building fails to satisfy the BASIX PASS requirement (i.e. BASIX score of 40%); 2) develop three solutions with combinations of appropriate sustainable technical options to improve the water performance of the case study building to BASIX score of over 40%, 50% and 60% respectively, and explain the reasons why you have chosen these solutions; 3) estimate the likely investment required for your developed three solutions and; 4) compare the three solutions you developed and discuss the advantages and disadvantages of each solution.

Sub-Task 2: Building thermal comfort. In this sub-task, your group needs to evaluate the indoor thermal comfort of the case study building provided, select appropriate technical options to improve the thermal comfort of the case study building to PASS the BASIX thermal comfort requirement and explain why you have chosen these technical options.

Sub-Task 3: Building energy performance. In this sub-task, your group needs to assess the energy performance of the case study building provided, analyse the potential solutions to improve the energy performance of the case study building by taking into consideration of the economic investment. This will consist of four steps: 1) calculate the BASIX score of “energy” of the original case study building, and analyse the reasons why the building fails to satisfy the BASIX PASS requirement (i.e. BASIX score of 50%); 2) develop three solutions with combinations of appropriate sustainable technical options to improve the energy performance of the case study building to BASIX score of over 50%, 65% and 80% respectively, and explain the reasons why you have chosen these solutions; 3) estimate the likely investment required for your developed three solutions and; 4) compare the three solutions you developed and discuss the advantages and disadvantages of each solution.

Format and submission requirement of the group report

Format of the report: Maximum length of your group report is to be 10 pages of A4 including diagrams and tables as well as appendices. Each group only needs to submit a final group report.

A written report from your group is due at 4 pm Friday Week 13, 1st June 2018, to the EIS Central.

Group Peer Assessment Form: Each report must also submit “Group Peer Assessment Form” with signatures from all group members. The form can be available from the Moodle site. Failing to submit the “Group Peer Assessment Form” or failing to have the signatures from all group members will result in a -5% penalty of the total final assignment mark.
