Lighting | Nexus

Nexus
  • built in 2002/3
  • 11 levels of residential apartments (88 apartments)
  • 3 levels of commercial office/retail suites (14 suites)
  • 4 levels basement car parking
  • meeting room and gymnasium
  • two residential lifts run from the basement levels
  • one commercial lift runs for four levels
  • central solar hot water to individual units
  • water cooled air conditioning tower services apartments

Awareness of minimum lighting standards and availability of new lighting technologies allowed Nexus to make simple, energy saving changes to their lighting in car parks and fire stairs. Changes included removing unnecessary fluoro tubes from fittings and installing new motion sensing LED's in Car Parks and Fire Stairs.

Case Study: Common Area Lighting

Since 2008 Nexus apartments has addressed the lighting requirements for each of its common area spaces. Here they talk about some of those initiatives.

Car Park Lighting (Phase 1)

  • 200 fluorescent tubes (in 100 fittings) illuminated 4 x basement levels, operating 24 hours per day
  • Lighting (LUX) levels were well above the Australian Standard
  • Most fittings were reduced from 2 to 1 fluorescent tubes
  • Cost: $0 as building manager carried out using own free time
  • Payback: Immediate

Carpark Lighting (Phase 2)

  • Fluorescent tubes replaced by multi-function LEDs with built-in microwave occupancy sensors in early 2012
  • Individual lights now only operate when and when they are needed

Fire Stairs Lighting

  • Fluorescent tubes replaced by multi-function LEDs with built-in microwave occupancy sensors in early 2012
  • Individual lights now only operate when and when they are needed

Note: installation of the multi-function LEDs above reduced the building’s total energy consumption by 25%.

Under Awning Lighting

  • Compact fluorescent downlights illuminated the street under awning, operating 24 hours per day
  • Installed a day/night detector to avoid 24 hour illumination
  • Cost: $200
  • Payback: <12 months

Plant and Utility Rooms Lighting

  • Fluorescent tubes illuminated Plant and Utility rooms, operating 24 hours per day
  • Installed motion detectors to avoid 24 hour illumination
  • Cost: $800
  • Payback: <12 months

Common Area Foyer Lighting

  • 240V ballasts were removed and replaced with low voltage ballasts and compact fluorescent lighting
  • Payback: 18 months

These are only some of several initiatives undertaken by Nexus since 2008.
