The façades respond intimately to their surroundings and make the most of the expansive views of the harbour , mountains and surrounding buildings .
High performance double glazing reduces solar gain in to the building and ensures excellent acoustics , removing the majority of noise produced by a busy working harbour environment . Solar and thermal performance requirements were set at a high level to meet the stringent energy requirements from within the building .
The tile chosen to clad the façade gives the impression of oxidised steel , supporting the industrial architectural aesthetic .
Important Elements Include :
• Central seawater cooling plant : Used successfully in No . 1 Silo , it was decided to use the same system throughout the district . As the central plant is seawater cooled it is very energy efficient . At certain times the seawater by-passes the chiller units and provides cooling at sea temperature straight
Sustainability The No . 5 Silo professional team are proud to have been awarded a 6 Star Green Star Office v1 Design Rating and Arup ’ s sustainability consultants are in the process of compiling the as built submission , also targeting 6 stars . This is the second building in the Silo precinct to achieve the highest rating awarded by the GBCSA , after No . 1 Silo .
Originally aiming for a 4 star Design rating on No . 5 Silo , it had become evident upon completing the energy modelling that the results were bringing in the building just short of a 6 Star Design rating . Upon discussion with the client , certain elements were re-evaluated in an attempt to obtain the additional points required . The building scored 75 points on the rating scale – 5 of which are innovation points .
