| 78 Waterloo Road is located in the heart of the rapid growth centre of Macquarie Park. The project is designed to achieve a 5 Star NABERS Energy (ABGR) and 5 Star Green Star rating with a strong focus on minimizing emissions, energy and water consumption and creating an office environment that maximizes occupant comfort and encourages alternative, energy efficient means of transport.
Energy efficiency is achieved through a 5 Star + 20% improvement NABERS Energy rating, metering on all major energy users using an intelligent web based system, tenant sub-metering, lighting control in 100 sq metre zones and an impressive lighting power density of 1.5W/sq metre/100 lux. In addition carpark, public areas, amenities and fire stair lighting is preset to off and activated by movement sensors.
Lighting to office floors is time controlled by the BMCS to eliminate energy waste through inadvertent out of hours use. Perimeter lighting zones are linked to daylight sensors that switch off lights when adequate natural light is available during normal office hours.
Fire stairs are provided in excess of the Building Code of Australia’s requirements and are designed to be external to the building with natural light and ventilation provided by full height glass louvre facades. The fire stairs are purposely designed to encourage pedestrian movement between floors thereby reducing the dependency on and use of the lift system to further reduce energy use.
Water efficient fixtures, waterless urinals, 4/3 flush toilet cisterns, the reuse of fire system test water, drain down facilities and stormwater reuse for irrigation minimize the building reliance on town water supply.
The project design is unique in its use of extensive balconies combined with operable external solar screens and louvres as external shading for the facade. The shading devices enable the use of single clear glazed facades that maximize natural light penetration and views while reducing heat load on the building interior. The balconies provide break out spaces for staff. High performance low E double glazing is used on the narrower, less exposed facades.
A central, naturally illuminated and ventilated atrium combines with the slender aspect ratio for the floor plate of the building pods to enhance the penetration of natural light and maximise external views.
Low VOC carpets, paints, adhesives and sealants with minimization of formaldehyde in composite wood products, high frequency ballasts, CO2 monitors to maximize the use of outside air in mechanical ventilation systems and high quality air change effectiveness complete the occupant comfort and indoor air quality of the building.
To ensure that the project realizes its design objectives, Lipman engaged the Green Building Council to conduct a project Green Star accreditation course for the construction team. The course was attended by all members of the team from project manager to construction worker as well as critical subcontractors. That dedicated group is currently developing a comprehensive commissioning strategy and programme to ensure that the building is finely tuned and functioning to optimum performance levels at completion.
