Customized Solutions
Does your building have the right amount of lighting? Are the lights located properly and are the correct lighting controls in place? What about the color of the lights? All of these factors affect not only your energy prices, but also the productivity of your workers and, if you are in retail, the success of your business.
Every Customer is Unique
For example An American Society of Interior Designers (ASID) study found that 68 percent of employees complain about the light in their offices. Furthermore, Metal Industries, a company in Elizabeth, PA, experienced an over 5% increase in productivity, which was valued at $1.5 million annually to the company. In addition, accidents became essentially non-existent, saving the company over $6,000/year on workman’s compensation claims and reduced insurance rates, and subsequent absenteeism dropped, saving the company an additional $225,000 annually*.
Our Lighting Audit involves measuring the illuminance, the color temperature, and the color rendering index, which measures how well the light source brings out colors.
Using the industry standard, the IESNA Handbook (Illuminating Engineers Society of North America), we can determine the best level of lighting output for your specific application. (See table below for general recommended illuminance values)
