Increases in productivity can now be quantified according to a 2013 World Green Building Council report. The report took into account a multitude of case studies and concluded that better lighting, like human-centric lighting, increases productivity by a staggering 23 percent. Extrapolating on an algorithm created by real estate investment management company JLL, a modest 2% increase in productivity leads to a savings of over $2 per square foot annually for a company with a total annual cost of occupancy of $10 million. So better lighting leads to more productive employees which in turn can lead to immense savings and revenue boosts for business and building owners.
