Detailed energy efficient lighting designs hold the key to cost-effective compliance with non-residential Building Regulations.
Lighting energy consumption in an office can account for 50% of the regulated energy use, and in a retail unit this figure is typically around 75%.
The tables below demonstrate the improvements which can be achieved by specifying an efficient lighting design, incorporating daylight sensing controls in areas with external glazing, and occupancy sensors in areas with intermittent occupancy. This is as opposed to simply entering the type of fitting used (e.g. T5s or LEDs), and using the default performance figures for that fitting without additional sensors or controls.
With the addition of detailed energy-efficient lighting design to the units below, they have gone from failing Building Regulations by more than 30% to comfortably passing them. The EPC ratings have also seen a large improvement.
