WEEK 9 ‐ 3D DETAIL ANALYSIS

Details: This detail outlines the glass spandrel panel, window frame and the ceiling/flooring system.

Spandrel Panel: Viridian Glass manufactures the opaque spandrel panel used. The glass is toughened and double‐glazed.

Low E Glass: Viridian Glass manufactures the glass above and below the spandrel panel. ‘Low E’ means Low Emissivity, which involves a coaHng that is fused when the glass is at its molten state. The coaHng is placed along one side and is much more energy efficient having beJer insulaHon and solar control.

Ceiling/Flooring System: The top most layers is a 2mm vinyl sheeHng. There is then 225mm thick steel reinforced concrete slab.

To connect the 13mm fire check plasterboard roof hangers are chemically aJached to the concrete.

Roof Hanger: The spring wire‐He ceiling hanger is connected to a cold rolled channel and below running perpendicular to the cold rolled channel are furring channels. This furring channel is what the plasterboard is screw to.

Building Processes: As for the flooring system, this secHon shows a major walkway so vinyl is used, as it is tough and durable.

Sustainability: The glass panels chosen really exemplify environmentally sustainable elements such as the extra insulaHon and solar control.

The choice of long lasHng materials such as concrete and vinyl also make the whole system much more sustainable.

The embodied water and energy to source, manufacture and build the materials though would be very high. The steel channels used in the ceiling as well as in the window frame use a lot of water and energy to create. As the glass panels have special elements within them, they too would also increase embodied water and energy in manufacturing.

The companies chosen to source the different parts are all Australian, thus slightly reducing the transport of materials.

Recyclability: The metal parts of the roof hanger and frame can be recycled and reused to create other elements. Concrete is not recyclable. Vinyl maybe broken down again to create new vinyl, however due to imbedded chemicals within it, it could potenHally have a large carbon footprint.

Economic: The steel channels used for the ceiling are specific to that type of hanger thus they would not be as easy to come by.

As the elements are much more specific such as the window frames and roof hangers, they would be much more costly. However, due to the size of building, the cost of these elements in bulk could potenHally be decently priced.

Structurally, the reinforced concrete is necessary however; due to its need there would be extra costs for materials such as the 2 types of channels and ceiling hangers unlike if Hmber floor joists were used where plasterboard can directly be nailed.

Things going wrong: The concrete also needs its verHces are shaped into 45 degree to stop any chopping, which could create weaknesses in the concrete.

The roof hangers need to be adjusted appropriately to allow for a level ceiling, as an ceiling that is not level may cause tension in certain areas.

The window frame has its own waterproofing but a waterproofing grout would be used around the edges where glass meets frame in order to stop any leakages.

The joints such as where the flooring meets the window frame would also need to be seal appropriately. The shadowline helps connect the plasterboard ceiling with the frame.
