Providing lighting controllability to 90% of individual-occupant spaces can add some upfront cost to your project if this is not standard practice. However, better lighting controllability can reduce lighting and cooling loads and increase productivity. A

Providing lighting controllability to 90% of individual-occupant spaces can add some upfront cost to your project if this is not standard practice. However, better lighting controllability can reduce lighting and cooling loads and increase productivity. Additionally, since ambient lighting generally is more energy-intensive and generates more heat than task lighting, emphasis on task-specific lighting can reduce energy costs by reducing the level of ambient lighting needed.
