Week 9 Journal:Last week, we explored the roof which was the project in assignment 2. The 1:1 scalemodel was made by some students and tutors. They showed and analysised details ofroof.

The whole was timber frame structure. We couldsee the load bearing beam and supportingcolumn clearly. Also, It showed the rafters. Thewhole material was timber. Such as thislaminated timber.

It was load bearing beam. It could support therafters.

The supporting column which was made bylaminated timber and it was the core to loadthe force from roof. In addition, the wholestructure used bolted joint to connect eachsection. “This is typically accomplished byusing a threaded hole that sinks through oneobject and into the next. A bolt then screwsdown into the hole and connects the piecestogether. This connection is exceptionallystrong, much more so than other commonforms of connection (McGee, 2013). ”

Then, we began the second activity---the presentation of the part of building. Iintroduced the structure and details of section12 in Ormand college. After that, tutorleaded us to draw the 3D image of case study building detail.

The left one is the part section of Ormand college and the right one is 3D image.

This is a 3D model, it was made by glassand plastic.This section could resist theheat flow through the roof.

Waterproofing: in this section, it uses flashing to prevent passage of water into astructure from an angle or a joint(Ching, 2008). Also, it has a weep hole which is usedin the render and the block work to allow for any potential water andmoisture(Ching,2008).

Economic implication of decision: The building uses glass as its frame, aluminum silland plastic. These materials are not too expensive to get, but these are necessary forthermal insulation.

Sustainability: Using aluminum is not really sustainable, because it can releaserelative high amount of carbon emission. However, it is necessary for windows tohold the weight.

Pros and cons: The pro of the window is that it can collect the light from outside andmake house become much brighter. It can save the electricity and it is an usefulinstallation to achieve sustainability. The cons is that the window is sealed, so it can’tget fresh air.
