PETER W. RODINO FEDERAL BUILDING, NEWARK, NEW JERSEY, USA
The high-performance building modernisation of the Peter W. Rodino Federal Building in Newark, New Jersey received a 2010 Design Excellence Citation Award in Engineering from the US General Services Administration. WSP Flack + Kurtz’s role included the complete renovation of the building’s nine fl oors, major system upgrades in ventilation, lighting, cooling and heating, and signifi cant sustainability measures, including facade confi gurations. These energy-saving features will reduce utility costs by approximately 32% annually.
The building retrofi t strategy involves wrapping the existing deteriorated precast concrete and single-glazed curtain wall with a new high- performance double-glazed exterior
envelope. The new double envelope has captive air space that can be sealed to retain heat during the winter and ventilated to shed solar heat gain in summer. Other strategies employed to reduce energy include:
• Water cooled oil-free magnetic bearing variable-speed chillers
• Fan coil replacement with variable- speed motor fan coils
• Retrofi t of constant-volume multi- zone air-handling units to variable- volume
• Lighting system retrofi t with occupancy and daylighting controls
• Photovoltaic array and solar domestic water heating
• Rainwater harvesting for cooling tower make-up
The energy conservation measures for the building are projected to reduce energy consumption and carbon footprint by over 50%.
Energy saving features will reduce utility costs by 32% and overall the energy consumption and carbon footprint by more than 50%.

222 EXHIBITION STREET UPGRADING, MELBOURNE, AUSTRALIA
This ambitious project involved the upgrading of an existing 1970s 30-level offi ce building at 222 Exhibition Street in Melbourne. With the aim of achieving both a NABERS rating and a Property Council of Australia A Grade standard, the renovation focused on energy effi ciency and occupant comfort.
WSP Lincolne Scott and its specialist environmental design service, Built Ecology, were involved since inception and provided an integrated service for the project, including environmentally sustainable development (ESD).
The green refurbishment involved the refurbishment of a total of 23 tenanted fl oors and was one of Australia’s most ambitious refurbishment projects. The project was made more complex by the fact that the 23 fl oors to be upgraded had to remain tenanted for the duration of the project.
The upgrading was undertaken in stages, with temporary relocation of tenants to other fl oors in the building until work on their respective fl oors was completed. The ability to refurbish with tenants in place represented a considerable cost saving to the client. The building services design primarily focused on energy savings achieved by intelligently regulating the building’s internal air temperature. This involved the replacement of the building’s existing ineffi cient chillers and the
progressive transformation of the existing “skin” air-conditioning system into an innovative “predominant mode” system, together with a more relaxed internal space temperature control range.
The renovation also included an upgrade of the main lobby, entrance, lower level amenities, levels 7-28 tenant areas and fl oor lift lobbies – a total of 23 fl oors, or 28,025m2 of net lettable area.
Other ESD features included upgrades to tenant and common area general lighting, lifts and the building automation system.
The project was completed in 2010.
