Charette City which is part of Urban Utopia is located in a Sub-Tropical Climate, in the Southern Hemisphere. As Brisbane is also a Sub-Tropical climate located in the Southern Hemisphere I have based by analysis on Brisbane data.
Figure 1.This Site Plan of Urban Utopia shows the topographical layout of the area, in particular the site location, Smart Stream.
Figure 2.This zoomed in Site Plan shows in greater detail the topography of the land. It also shows the location of the 3 Exemplar Houses and the proposed Cabin Location.
Figure 3.This enlarged Site Plan shows the access points to the exemplar houses as well as the proposed cabin. The forest has been coloured in a darker green and is located at south of Smart Stream. Above Smart Stream is an almost flat plan where Lambert House and Balaam House are located.

Figure 4.The diagram on the left shows the sun over a property in Brisbane throughout the year. Sun angles and shadows can then be determined. The diagrams on the right show wind directions. The top diagram is in July and shows strong South Westerly winds. The bottom diagram is the Summer months and shows strong North Easterly winds. I have then designed my building with these factors in mind.
Figure 5.This site plan shows summer wind directions that have been calculated from Brisbane wind directions.
