AN EVEN GREENER SYDNEY TOWER
A
s an integrated firm of expert engineers and project planners, Norman Disney & Young (NDY) has added value to landmark projects nation-wide, such as Sydney’s CBD icon, Centrepoint (now known as Westfield’s Sydney Tower), for which NDY provided consultancy services for Mechanical Services from initial design and construction. NDY’s experience gained as consultants on major shopping centres including Macquarie Shopping Centre, Warringah Mall, Chatswood Chase and Castle Towers, has been put to work on Westfield Sydney Tower’s redevelopment, resulting in Five Green Star.. As part of the upgrade of Centrepoint to incorporate the amalgamation of Imperial Arcade and Skygardens, NDY was engaged by Westfield to provide D&C consultancy works on all building services - Mechanical, Electrical, Vertical Transportation, Fire and Hydraulic Services - for the upgrade of 100 Market Street; the new office tower fronting 85 Castlereagh Street above the retail area; demolition of Imperial Arcade to allow provision of new carparking spaces under and retail areas for amalgamation into Skygardens and Centrepoint; and upgrade and reconfiguration of retail areas in Centrepoint and Skygardens. NDY was involved in implementation of 5 Green Star services including high efficiency chillers, domestic cold water storage and energy efficient air conditioning systems. NDY also undertook the tenancy fit-outs for JP Morgan and ASIC, ESD services for ASIC and was involved in the smoke extraction logic within the retail areas. NDY specialist division, NDYLIGHT undertook lighting design, lighting design advice on local fixtures, BCA Section J assessments, lighting modelling and shadow diagrams for a number of key retail outlets.

and energy efficiency was the key, with LED technology offering a very low maintenance option. NDY’s initiatives included a low temperature VAV air conditioning system within 100 Market Street to suit the existing 3.1m slab to slab height, giving tenants extra ceiling space; provision of active chilled beams on the perimeter of 85 Castlereagh Street and low temperature VAV system within the interior areas; and provision of constant volume and VAV systems within the retail areas. “A significant challenge was ensuring part of the centre remained operational, so design and implementation had to be staged around continued trading. We had to minimise dust and noise and incorporate public safety thinking in design,” said NDY senior retail expert, Graeme Oakley. According to NDY Director, Ashak Nathwani, NDY involvement in all services allowed an integrated approach. “For example our involvement in lighting meant there would be less heat output from lighting, which provides a benefit with the air-conditioning.” “NDYEnvironment (the specialist ESD division) assisted in addressing the practical aspects of some of the ESD ideas put forward by the Westfield team which includes a Tri-generation System and Black Water System. NDY was instrumental in lengthy negotiations with the relevant authorities, since this was the first time such technologies were being considered for implementation in the Central Business District (CBD) area.” NDYEnvironment recently scored the sustainability trifecta of 5 Star for Design, As Built and Interior for their own Melbourne office, and have been responsible for ESD innovations in landmark projects across Australia.
