Bilevel Stairwell Lighting Promises Up to 70-80% Energy Savings

Stairwells are trafficked an average of 3-5% of the average day, but many building codes require constant illumination. Manufacturers have responded with automatic bilevel control solutions that save energy by alternating between low (energy-saving mode) and high (occupied mode) light levels based on occupancy. As this approach is required in ASHRAE/IES 90.1-2010, which will become the minimum standard for all commercial building energy codes starting October 18, 2013, it will soon become standard practice.
