Industrial Buildings Can Save On Energy Costs With Lighting Retrofit

the May 2010 issue of Buildings magazine had an excellent article on unique energy saving opportunities for industrial buildings. For full coverage please visit www.buildings.com

Energy and operational efficiency are incredibly important, especially as everyone is trying to be cost conscious and making sure that a facility is competitive in terms of occupancy," says Joel Pizzuti, president and COO of The Pizzuti Companies. "Trying to determine ways to cut energy costs and looking at different ways to become LEED certified or operate as a sustainable building are important, too."

Tenants are looking not only at lease rates, but also at operating expenses, he explains. "It’s important for owners and property managers to make sure the operating expenses are as controlled as possible. People are scouring their budgets to look at ways to save money; in doing that, it’s important to make sure we still maintain a really high level of service for tenants."

While it may be an extra upfront expense for you, one way to cut operating expenses is to employ alternative energy solutions. The Pizzuti Companies did this by installing prismatic skylights when it built a new facility in Chicago ."We put in a series of prismatic skylights that act as a way to light the building using natural light and not as many high-bay lighting fixtures," says Pizzuti. "This is resulting in a 20-cent decrease per square foot to run the building over the span of a year. On a clear day, we can get 45 to 50 footcandles of natural light inside the warehouse."

Adding skylights are an upfront cost, "but we felt like, long term, it would add a lot of value to the building, cut down on the expenses for our tenants, and make us more competitive when we’re trying to lease the facility," says Pizzuti. Happy tenants and easier leasing down the line make a nominal upfront cost more than worth it.

If natural lighting isn’t an option, the use of energy-efficient lighting is another way to cut operating costs. Think about installing a T5 or T8 system with occupancy sensors. "If somebody is moving within an aisle of racking, that aisle will light up. As they leave, the warehouse lights won’t stay on in areas where nobody is working," says Lance Ryan, vice president of marketing and leasing for Watson Land Company. "Over time, there’s a huge savings in terms of utilities, and [we’re seeing] up to a 50-percent reduction in utility costs with energy-efficient lighting. In addition, you’re also lowering ongoing maintenance because you’re not using warehouse lights as frequently, so your energy-efficient lighting doesn’t require a change-out as frequently."
