NSW Land and Housing Corporation project learnings
115 social housing LED lighting upgrade project results
8250 Chamaeleon light fittings (75% emergency) installed by enLighten Australia across seven rounds of successful open tender wins from 2011-14.
1) Good tender design is crucial to understand the full project costs & benefits
Key evaluation criteria -
- energy savings,
- payback periods,
- supply & installation costs,
- warranty periods,
- ongoing maintenance requirements,
- ability to replace components
- replacement costs,
- company experience,
- capacity and personnel
2) LED emergency lights are approximately half the cost of the former vandal proof T8 fluorescent emergency lights to install with a rated life of over 4 times longer (50,000 hrs v 12,000 hrs)
3) The internal motion sensor of the Chamaeleon light within the vandal proof fitting was more robust & offered a technology advantage over other lighting systems with an external motion sensor. In 3 years of installations there have been no reports of vandalism of the Chamaeleon light.
4) Advantages of using a specialist lighting contractor over a maintenance or electrical contractor include:
- Experience and ability to implement custom solutions to meet Australian Standards compliance, as most projects involve addition or deletion of lights
- Can include make good for all surfaces from scope of works
- Can obtain information for Energy Savings Certificate (ESC) generation documentation requirements - photos, light level measurements, recycling certificates, pre & post lighting plan
5) Motion sensor timings can be suited to the area of use.Common settings for residential properties:
- Fire stairs - 15 seconds
- Corridors - 60 seconds
- Car park - 90 seconds
6) Energy savings results from lighting upgrades ranged from 37% to 61% of TOTAL site energy use.
