INTERROGATION OF OF DETAILING DECISIONS AND PURPOSE
Week 09
Acrylic trowel on render stretcher bond block work allows for even distribu;on of a load across the wall
Cavity between exterior block work wall and insula;on prevents moisture reaching the interior Insula;on secured to the concrete floor slab with a stud
The glazing adaptor fixes the glass sheet to the block work wall
Wall of exis;ng building
WATERPROOFING ELEMENTS
Week 09
Weep holes are mortar free perpends that allow the water than accumulates on the waterproofing membrane in the cavity between the block work wall and insula;on to escape
The sarking consists of an aluminium foil and acts as a waterproofing sheet that prevents water passing from the exterior to the interior across the cavity between the block work wall and insula;on. The moisture collected on the sarking is drained by the Colorbond flashing which guides it back out through near below the weep holes.
ECONOMIC IMPLICATIONS OF DECISIONS
• Copper cladding is a costly material and thus has been sparingly applied across the façade • An in situ concrete floor slab may have been the cheaper alterna;ve, reducing transporta;on costs that are associated with precast concrete however, this may have been overcompensated with addi;onal labour requirements • Colorbond is an expensive material but creates a very modern affect in the design. Furthermore, it is very durable and therefore, well-‐suited to the waterproofing func;ons it plays within the exterior walls • Scoria blend blocks are low cost and hence ideal for non-‐ loadbearing walls • Though more expensive than a ;mber frame, a steel structural frame was required to allow for par;cular design effects such as non-‐load bearing walls of low-‐strength materials.

SUSTAINABILITY AND ENVIRONMENTAL ANALYSIS Material: Aluminium Use: Sarking, mullion and glazing adaptor Proper;es: light weight, corrosion resistance, electrical and thermal conduc;vity and duc;lity Availability: expensive however available from variety of manufactures Carbon footprint: high Recyclability: Aluminium is 100% recyclable and experiences no loss of proper;es or quality during the process which uses only 5% of the energy used to created new aluminium. Embodied energy: Highly energy intensive manufacture
Material: Colorbond Use: Flashing Proper;es: corrosion resistance, colour reten;on, high tensile strength, fire resistance and resistance to abrasion. Availability: expensive however available from variety of manufactures Carbon footprint: moderate Recyclability: steel can be recycled without losing proper;es or reducing performance Embodied energy: moderate
Material: Glass Use: Roof of sunroom Proper;es: transparency and hardness. Availability: expensive however available from variety of manufactures Carbon footprint: low Recyclability: !00% recyclable Embodied energy: low
Week 09
Material: Scoria blend blocks Use: non-‐loadbearing walls Proper;es: low mass and good insulator Availability: expensive however available from variety of manufactures Carbon footprint: low, poten;ally only related to transporta;on Recyclability: can be reused Embodied energy:
Material: In situ concrete Use: floor slab Proper;es: high compressive strength and low thermal expansion Availability: expensive however available from variety of manufactures Carbon footprint: low Recyclability: almost 100% of concrete can be recycled Embodied energy: low
