Typically, once an agreement has been made, our technical staff will contact you within one business day to set an appointment to perform your predominant use study within a week or two. The amount of time at your facility is minimized since our associates have performed over 21,000 predominant use studies and will be familiar with the power-draw of the common components such as lighting, HVAC, computers, refrigerators, etc... The raw data is compiled at our headquarters to further minimize time at your facility. The study is normally completed and certified by our Professional Engineer within one or two days of the site visit.
