What the $3-$30-$300 Shift Means for the Lighting Industry

Lighting Industry Shift Controls

Many have heard about the “$3-$30-$300” rule (though in some markets it’s called the “$8-$80-$800” rule), which relates to the magnitude of certain expenses required to conduct business in a commercial space. Though the numbers may vary we can slice the cost of doing business into three segments. 

Picture an inverted triangle: the first layer from the bottom, the “$3” is the total cost of energy per square foot to run the business; the second layer or “$30” is the cost of the commercial space per square foot; and the third layer at the top is “$300” and is the cost per employee. 

This rule has often been applied when talking about energy or sustainability programs and improvements like lighting, and how it affects these three areas (most importantly regarding cost savings and productivity increases). 

While a 5% improvement in energy efficiency equals a savings of $.15 per square foot, the same percentage of improvement in productivity equals savings of $15 per square foot. So, the biggest value and opportunity has always been in the “$300” layer of people and productivity. Though energy savings cannot be directly correlated to increased productivity, in the lighting controls industry we’ve been able to balance energy-efficient lighting and the customer and end-user experience (e.g. comfort, safety, productivity, etc.). And there have been studies that have been done that support increases in productivity with energy efficiency improvements, especially in the area of lighting controls.

There is a new opportunity in the top people and productivity segment and that is human centric lighting — a topic that has received a lot of attention in our industry in the last few years. There are many fields that are interested in colour tunable or tunable white solutions — commercial, education, healthcare, hospitality, retail, and the list goes on — to help improve productivity, well-being, comfort, and more. 

For us, the hope is that we can take the lighting controls that are mandated, which affect cost of energy per square foot ($3), and value in the productivity segment ($300). While human centric lighting is still in the early stages, I believe that there will be telling research about the productivity benefits in the near future. We are seeing more studies, trials and solutions and technologies coming into the market. We need to understand the productivity and cost benefits further and be able to accurately quantify those benefits.

We also want to make the point that, in order to achieve the maximum benefits, a space has to have great lighting. You can’t achieve great lighting by adding controls to a space with adequate lighting.

In addition to human centric lighting, there are still future opportunities to create a good foundation for good lighting and control that help in this new transformative era for our industry.
