Continued… Primary structures:

Rafter- supports the weight of the roof Secondary structures:

Bricks- supports load of the fascia and provide enclosure Tertiary structures:

Metal deck under metal box gutter- required to support the weight of storm water as metal tray will not be able to withstand the weight

Sustainability and environmental analysis Bricks are considered to be relatively sustainable as they are:

reusable durable locally produced bricks have little embodied energy no toxic emissions produced during manufacture

However, there have been concerns about the guarantee of quality bricks (Greenspec 2013). Earthwool products are also environmentally friendly because:

it uses a technology which reduces its embodied energy made using recycled glass bottles other materials used are renewable (Knauf Insulation)

Where and why things go wrong Many failures in buildings are usually caused by air leakage or water-related elements around the enclosure of a building which leads to condensation and eventually growth of molds. This is why the use of insulation is extremely essential in buildings as it prevents air leakages which causes condensation. Weep holes are also important as they allow moisture to escape to prevent condensation inside bricks.
