Tool to calculate costs of lighting improvement

Support provided by Zero Waste Scotland

What does this involve?

An energy-efficient lighting upgrade could save you cash while helping the environment. Discover how much you could save based on your number of light fittings and estimated running hours per year.

Our lighting improvements calculator will walk you through 3 alternative lighting projects, looking at:

  • initial layout costs
  • potential savings
  • payback period

For those who don’t require a complete refit, the calculator offers a more detailed analysis, taking into account existing fitting types, wattage, and previously installed control systems.

The data provided by this user-friendly tool includes:

  • annual savings in kilowatt hours (kWh), money and carbon dioxide
  • whole-life costing, to account for periodic replacement costs

The tool is in the form of an Excel spreadsheet (221 KB) that you can download and use to plan your project.

What does this cost?

This is a free service.

Who is this for?

Any business seeking ways to cut energy consumption, costs and carbon emissions.

How long does this take?

The time needed to use this tool will vary depending on what data you already have prepared.
