Daylight Hour

Daylight Hour is an annual social media campaign organized by the Building Energy Exchange to raise awareness about using natural daylight in lieu of electric lighting in offices. Launched in 2014, this simple and engaging campaign asks offices to turn off non-critical lights in day-lit spaces from noon until 1 pm on the Friday nearest the summer solstice.
