Environmental Impacts of Multi-Storey Buildings Using Different ...

- 28 -members, floors are timber / concrete composite and the external cladding is fibrecement.TimberPlus building – as for the Timber building above but with greatly increased use oftimber throughout including timber external cladding and cedar windows andlouvres, solid timber internal walls, timber ceilings and other features whichmaximise the use of timber throughout the building.• The Concrete building design is very similar to that provided by Courtney Architects.• The preliminary Steel building design was provided by Steel Construction NewZealand Limited and modified by structural engineers from Holmes Construction andthe University of Canterbury, with architectural design by Victoria University ofWellington (VUW).• The Timber and TimberPlus designs were produced by engineers at the University ofCanterbury, with architectural design by Victoria University of Wellington (VUW).In each design, the objective was to use as much of the target material as reasonably possible,both in structures and finishes. However, to standardise - and adhere to “good NZ designpractice”- for the Concrete, Steel and Timber designs, many interior and exterior finishes areas commonly found in typical NZ multi-storey buildings and similar in each design. Forexample, windows, curtain walls in the north and south façade, sun louvres in the northfaçade, roof cladding and internal finishes such as most of the linings and ceilings are thesame.The TimberPlus building was designed so that all possible ‘common finishes’ of the Timberbuilding were replaced by timber components.Figure 4.2: Plan of the simplified layout used in the concrete, steel, timber and TimberPlus buildings.
