Here’s a story to brighten your day! ;) On May 29th, we completed a retrofit of the Zappos South Garage’s lighting by replacing the old, yellow high-pressure sodium (HPS) fixtures with bright white, energy-efficient induction lighting fixtures. The Zappos garage is quite large and offers parking for more than 600 cars.
Garage lighting retrofit projects are the ultimate low-hanging fruit in the sustainability world. In addition to providing superior illumination, the Zappos retrofit is projected to reduce the annual energy consumption of the garage by two thirds! That’s 323,000 kWh/year; the equivalent of roughly 25 homes and a reduction of 223 metric tons of CO2e emissions.
Induction lighting is really cool and dates back more than a century to when Nikola Tesla advanced the technology in the 1890s. Induction is unique because the power required to generate light is transferred from outside the lamp envelope to the gas inside via an electric or magnetic field. Benefits of induction include long life spans, low heat output and excellent color. The Zappos induction lamps are even more advanced. The lamps have two brightness levels, dimming controls, daylight sensors and occupancy sensors – reducing the “ON” hours and saving even more energy!
