A brighter, greener way to build



Construction sites are typically lit up as brightly as Christmas trees all night, long after workers have gone home.

But just as a greater focus on energy conservation has made high efficiency lighting and occupancy sensors commonplace in finished buildings, why can’t contractors use greener solutions for lighting buildings still under construction than always-on incandescent or metal halide fixtures?

Skanska decided to tackle the issue head on, working with Clear-Vu Lighting of Westbury, N.Y, to develop temporary LED stringers. The LED luminaries not only use less electricity than incandescent bulbs, but they are brighter as well for increased safety. Another safety aspect is that low-voltage wires – rather than those carrying potentially dangerous 110 volts – connect LED fixtures. That the LEDs last much longer than other bulbs reduces maintenance costs. And no more having your jobsite lit at full force all night: Clear-Vu incorporates a time clock that can dim the lights during non-working hours.

Skanska piloted the LED jobsite lighting in 2009, and it was a great success. Today, several Skanska projects are using it; with more to follow. We’ve found that the LED lighting pays for itself in three-to-five months, depending on utility rates. For instance, at one of our higher education projects in the Boston area, purchasing the LEDs cost $100,000. However, the LEDs saved more than $300,000 in energy costs throughout construction. Even better, this product may earn a LEED Innovation in Design point depending on how it’s used.

With this LED lighting solution, we’ve found a way to make construction a bit greener. And that’s a win for everyone.
