Lighting, Low-Carbon Means Low-Cost!

Continuing with our theme of energy reduction opportunities, this month we look at low-cost measures that can be easily adopted, quickly implemented and capable of showing quick results.

Lighting – Measure, Monitor, Minimise

Remember the three golden 3M rules, Measure – Monitor – Minimise!

These 4 lighting measures can be used to reduce your carbon footprint and save energy at little or no cost:

  1. Daylighting – maximise daylight usage, after all sunlight is free! Open blinds or window shades, use skylights or other natural light sources effectively and switch off lights if you don’t need them to reduce electricity consumption during daytime hours. This is of course seasonally adjusted but will make a real difference if you implement a 3M approach. You may see between 10-40% reduction in your lighting bill.
  2. Use task lighting where possible (point of use direct lighting for specific tasks) instead of illuminating an entire room.
  3. Of course implementing a regular lighting maintenance plan is critical in ensuring the existing lighting is not only working at optimal performance, but to reduce down time through flickering or faulty light fittings. A good planned preventative maintenance regime will ensure this is done annually.
  4. Remove unnecessary lamps (de-lamp) in overlit areas. Check your light levels against standards from the Illuminating Engineering Society (IES) to see if you have areas that are over- or under-lit, easy to do, quick to resolve and can deliver real savings.

COP26 and Rapid Payback Measures

Next month we will be reviewing the outcomes from COP26 and discussing rapid payback measures that can be easily carried out at relatively low cost.

Energy – If You Can’t Measure it, You Can’t Manage it!

Before you embark on a major project to reduce energy consumption, do you know where you currently use energy? That is the vital starting point, as RFM’s Client Services Director Mark Flanagan explains.
