This assignment isrelevant to the following Learning Outcomes:

1. Identify implications of site limitations including evaluation of existing buildings.

2. Describe the environmental impact on construction and services.

3. Evaluate examples of sustainable design and construction practice.

Answer all five (5) questions. Marks allocated are indicated for each question

You have been asked to carry out a site assessment to determine the site implication and environmental impact for a proposed new residential development in Mount Roskill, Auckland. The proposed new building is to replace an existing timber framed building. The client has arranged that the existing building will be moved to Kaikohe. Once this building is moved, the new construction can begin. The existing building is a three-bedroom timber framed building (single floor).

• 2 storey building

The area is fully developed and all adjacent buildings are single storey buildings. The area is a Residential - Mixed Housing Urban Zone as indicated in the Auckland Unitary plan.

6. Homestar is one of the green building rating tools designed specifically for use on residential buildings. Homestar was developed from successful international rating tools which has been adapted for New Zealand’s specific conditions. Homestar as a rating tool is supported by the New Zealand Green Building Council NZGBC. NZGBC website highlights a few success stories of buildings that have been rated using Homestar to showcase some healthy, efficient and sustainable buildings. You are required to visit the NZGBC website, to select an example of a building which has not less than an 8 star rating. Evaluate five (5) sustainable design features (minimum of 50 words each) in your selected success story (10 marks).
