Good lighting design means the right amount of light in the right places, not over lighting and not having lighting on when not required. Done right it can:

• Optimise lighting levels for accuracy and safety
• Enhance architecture
• Add to the 'look and feel' of a space
• Highlight products in a retail environment.

There are psychological benefits too - good lighting design is is an essential part of people's feelings of comfort and satisfaction, providing productivity benefits in the short run and potential employee retention in the long run.

Most people spend on average 8 hours a day in the workplace

So it is important to ensure they feel comfortable in that space. Here's what you can do:

• Maximise natural daylight levels, while avoiding glare
• Light walls and ceilings with bright room surface finishes, so people can safely move around the space
• Provide the correct colour rendering and colour temperature to improve the feeling of comfort
• Allow for zoning so people can dim lights or switch them off when they are not required, thus saving on electricity.
