by

Sunlight gives us light at no charge, which we can harness in our buildings to reduce our reliance on electrical lighting, while providing a more enjoyable indoor environment. Leave it to an engineer to tell us how much that sunlight actually costs us. Lumens per watt (lpw) is the measure of lighting efficacy, telling us how much light (lumens) we get out for how much power (watts) we put in.
