Whilst a lot of effort is put into producing low-carbon new buildings, the elephant in the room is the refurbishment of existing buildings, where there are many more constraints on the design. It is estimated that 66 per cent of the 2050 building stock already exists.
There are still far too many buildings where no thought has been given to the lighting. They are dull, energy-inefficient and do nothing for the users.
Energy regulations such as Part L are often used as an excuse for poor lighting design. But regulations are just another constraint on the lighting design in the same way that budget, client taste, timescale and the architecture are.
Any journal that shows how the lighting can be made better for the vast majority of our ‘unseen’ buildings is to be welcomed.
