d) Galvanised Steel – (GAL) Page: A04:03 Galvanised steel would have been used in the roof structure of this area, as seen in the image below, there was galvanised steel beams that would’ve been bolted to the existing buildings in order for the roof to hold lateral and vertical forces.

6. SUSTAINABILITY AND ENVIRONMENTAL ANALYSIS: a) CARBON FOOTPRINT: There are certain areas of this development where there is evidence that proves that the developers have taken into account the carbon footprint of this development, some of these instances include: •
•
Skylight – The skylight allows for natural light to illuminate this corridor by simply leaving an area in the ceiling which has not been plastered and is inbetween steel framing. Whilst the skylight does not fully light the whole area, it decreases the reliance on electric lighting Insulation – There has been insulation included in the walls and ceilings in order to minimise the dependence on heating that would require gas or electricity, as we can see below in a wall section ‘Insulation Blankets’ have been stuffed in between the exterior walls and the plaster boards in order to maintain temperature at a desired level
•
There are areas in this development where the use of plasterboards have been spared, as you can see from the image below (taken from the site visit), rather than plaster boarding an area of existing bricks, the developers instead have just painted these clay pressed bricks white.
b) EMBODIED ENERGY: Embodied energy is the energy that is required to produce materials. It could be said that this development conserved embodied energy because rather than creating a stand-alone structure, this structure was built upon two existing buildings. The footings of this structure was also a pre-existing concrete slab with existing pier footing supports, this meant that no excavation had to occur and pouring of cement was not needed. However, using a steel frame as the roof structure has more embodied energy than using a timber frame roof structure, so environmental analysis was not favored in this decision. c) RECYCLABILITY: Recyclability of pre-existing materials was obviously a decision that was prevalent in both primary and secondary materials. From a primary structure perspective, the existing concrete slab acts as a foundation for this section of the MLSE, also the load-bearing capacity of the MLSE and MLSU buildings allow for this corridor to stand. Recycled bricks have also been used for aesthetic purposes, rather than plastering and ‘covering up’ areas where secondary materials would normally exist. The developers have chosen to leave existing bricks out in the open.
7. ECONOMICAL IMPLICATIONS OF DECISIONS: There are decisions that have been made in this development which have proved to have beneficial economic implications as well as negative implications in this development. A positive economic implication includes the use of a skylight, by designing this structure with a skylight, money will be saved through the use of natural light rather than having to light the building with electric lighting. Another example could be seen as using recycled materials as well as conserving uses of materials such as plasterboards (e.g. painting existing bricks white) A negative economic implication may relate to the aesthetics of this development. Whilst the glass walls are very appealing to look at, this was a decision that would’ve proven to be incredibly costly where the developers could have used a cheaper material for a wall. Another example includes steel framing for a ceiling structure, whilst it is much sturdier than a timber roof structure. This method is much more expensive.
