You do not need solar panels to make electricity when the first step is to reduce your waste and SAVE money.
Why not let natural light through certain doorways to enhance interior rooms and save money? Transoms and translucent glass doors add interest and reduce your need to power light fixtures.
Why flip a switch to light an interior bathroom or closet, when the sun can shine down and into the space? Sun tubes are great when a skylight will not work due to an attic or obstructions, and the light fills the room, naturally.
Why keep the sun out when new technology reduces summer heat gain and lighting is one of the major costs of operating an office. ENERGY STAR® qualified 'Low-E' skylights help reduce your energy bill up to 15%, so they save money for as long as you lease or own your office.
