The Client

Perenco

The Brief

Repair and replacement of faulty lights before Perenco moved into the new premises at Peel Ports Great Yarmouth.

The Result

After speaking to the client during our site visit, I explained that repairing the existing faulty lights would be a more expensive option in the medium /long term as these lights were old, inefficient and would require regular repairs.

Based on our research, we recommended a complete lighting upgrade, providing cheaper running costs and increased energy efficiency.  We made a presentation to Perenco with a full lighting specification design and a breakdown of our installation costs.  

After the work was approved, we carried out the complete lighting upgrade in the new Perenco warehouse and workshop areas.  This involved disconnecting 112 lights fittings and replace with 36 new LED warehouse lights which vastly increased light output, whilst simultaneously significantly reducing running costs.

The Client

DSL

Derrick Services (UK) Ltd. Great Yarmouth

The Brief

Find a solution to save energy and reduce running costs.

The Job

Danny Daniels from DSL contacted AC Electrical to talk to us about ways they can saving energy and reduce the running costs of the lighting in the communal areas of the building such as the corridors, kitchens and toilets. We carried out a site survey of the installation and looked at what was installed and what the LED equivalent would be.  To further increase energy and cost savings we proposed to install occupancy sensors in all areas to allow the lights to operate only if they were occupied and if the natural light levels required it. We were able to fully adjust the occupancy sensors to the natural light levels and time settings for each different area, ensuring lights were on only if required and for the minimum amount of time necessary before dimming down and turning off.

Over the course of four days:

  • Removed 47 light fittings
  • Rewired the lighting circuits to allow all the areas to be sensor controlled
  • Remove redundant light switches and blanked off 
  • Supplied and fitted:
  • 29 x OVIA OV74301CWB LED PANEL 30W
  • 10 X OVIA OVMS001WH MICROWAVE SENSORS
  • 10 x OVIA OV9110010/16W MICROWAVE  LED BULKHEAD 
  • 4 x OVIA OV82150 MICROWAVE  42/48/54/60W 1500MM LED BATTEN 

The Result

  • Over 50% reduction in energy and running cost compared to the original installation.
