Examples of lighting controls cost savings

This case study shows the impact of lighting controls on whole building energy costs.


As an example of the cost savings that lighting controls can generate, we have performed a case study of two 24-hour facilities and the impact the lighting controls time schedule has on the whole building energy costs. The energy costs included in this case study account for the reduced lighting load and the impacts to the cooling load and heating loads for each building when the lighting is controlled by a time schedule. For both projects the cost savings in energy usage results in a simple payback of less than 4 years for the lighting controls equipment, labor, and start-up/commissioning.

The two 24-hour facilities evaluated in the case study are mixed industrial and office spaces of 300,000-650,000 sq ft. The lighting in the industrial work areas is controlled with a time clock used to switch lights keyed to specific zones by shift schedule. The control equipment allows zones to be reconfigured down to a fixture level, and fixtures are switched on/off with the time clock schedule or by a timed override switch for each zone. The analysis considers only the industrial area lighting controls system, labor, start-up, and commissioning.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
