The eco guide to a happier, greener workplace

Natural lighting or at least LEDs will improve your mood, and there are other positive steps to take to make the office a more world-friendly environment

If you're dreading the start of the working week tomorrow can I just check it's not the lighting? A 1990s study showed plentiful natural light to be a top determinant of job satisfaction.

If you can't get near a window at least press for LEDs (they have a life of up to 60,000 hours in comparison to 6,000 hours for a fluorescent tube). They also improve your mood, productivity and energy efficiency.
