US Energy for Lighting
Electric Lights Use Energy
Lighting uses 273 billion kilowatt-hours of energy across the US.
That’s 7% of total US energy consumption.
Daylight Uses Zero Energy.
What Actions Can We Take to Make a Difference?
What to Do
What to Say
Make an effort to notice skylights and windows at the grocery store, at work, at the doctor’s office, even in your own home. If you don’t see enough sunlight, tell someone. Building managers, facility operators, architects, construction companies… they need to know that we care about natural daylight.
They need to hear it from all of us: everyone has a #RightToDaylight.
- NATURAL DAYLIGHT BURNS NO FOSSIL FUELS
Natural interior daylight (NID) saves energy. Daylight uses no electricity and burns no fossil fuel. Despite the market obstacles, buildings that use natural daylight save on energy costs, especially when daylight sensors and controls reduce the electric lighting. It may be one reason that homes with better windows and skylights increase in value faster.
- NATURAL DAYLIGHT IS HEALTHY
People need windows and skylights because exposure to daylight is healthy. Studies demonstrate that the biological benefits of daylight significantly increase human performance outcomes, especially in classrooms, and is the reason that top universities insist on using natural daylight. Workers in offices with daylight have fewer sick days. Natural daylight is commonly used in health care facilities as well.
- NATURAL DAYLIGHT IS THE BEST LIGHT SOURCE
Colors appear more vivid under daylight. Daylight brightens homes and helps people to discern colors. Visual acuity for examining small details is significantly improved. In fact, colors are so much better under natural daylight that auto sales increase in dealerships that use skylights. From office workers to firefighters, people appreciate the benefit of daylight where they work.
