Resource usage should be minimised where ever possible to reduce any negative impact on the environment.
It is very important to not only reduce the usage but also discover techniques to provide alternative energies.
One site achieved this by implementing solar powered tower crane lighting:
- All cranes on site were previously equipped with aircraft warning red beacons that needed a constant glow of 200 candela, powered by diesel generators;
- Diesel generators were required to remain running throughout the night to keep this single warning beacon illuminated;
- As well as the cost of fuel, this also increased noise levels (during the night) and carbon emissions;
- A fire fly unit was introduced to one of the shorter cranes. The unit harnessed and stored solar energy to keep the light running throughout the night. This had a battery back-up solution to help when the sun did not shine;
- This enabled the current on-site generator to be switched off at the end of each working day;
- The technique achieved an effective and staggering 50% carbon reduction.
