At Sloan-Kettering, LED lighting manufacturer Seesmart Technologies replaced about 700 fixtures, switching out fluorescent T8s and T12s in the facility’s parking garage with Seesmart T8s. This will reduce the hospital’s energy cost by almost 57 percent, or $2,500 per month, according to the lighting company.
Memorial Sloan-Kettering also slashed its energy consumption by 160,000 kWh annually, earning it a $22,000 rebate from energy company ConEdison. The hospital anticipates a full return on investment within two years.
Following the project with Memorial Sloan-Kettering, two neighboring organizations – one residential center and one medical center – commissioned Seesmart to help them transition from low-efficiency fluorescents to LED tube lights.
On the other coast, Daintree Networks installed an integrated intelligent lighting system consisting of Cree’s energy-saving LED fixtures and Daintree’s ControlScope wireless lighting controls solution at the Sacramento facility of United Stationers, a wholesale distributor of business products. The retrofit, in the company’s office and break room area, is expected to cut lighting costs by 91 percent, according to the lighting companies.
With the assistance of Collins Electrical Company, United Stationers replaced hundreds of fluorescent fixtures across the office with Cree CR Series LED Troffers, reducing the number of fixtures and lowering maximum wattage.
The retrofit also uses integrated intelligent controls from Daintree Networks to save energy. Daintree’s Wireless Area Controller communicates with the fixtures through an integrated adapter, and the facility has added occupancy and photocell sensors. Lighting settings, including occupancy, daylighting, scheduling and task tuning, are all managed over the web through the ControlScope Manager software interface. Each occupant has also received a remote wireless dimmer, allowing them to set their light level according to personal preference.
Earlier in April, nuclear measurements company Canberra completed a lighting retrofit at its in Meriden, Conn., facility using Noribachi Illumination LED products, expected to save 63,000 kWh and $15,000 a year.
