Illinois has a new energy code, which means key changes are coming to those working in the lighting and electrical industry in the state. Effective March 1, 2019, the 2018 International Energy Conservation Code (IECC) becomes state law across Illinois.
Another change with the adoption is that state funded buildings now follow the 2018 IECC with ASHRAE/IESNA 90.1 as an alternative compliance path for a building owner and design team. Any building plans submitted on or after the effective date are expected to follow the new energy code requirements.
The updated code will increase energy efficiency and lower energy operating costs for commercial buildings. Harold Jepsen, Vice President of Standards and Industry, Building Control Systems at Legrand, has outlined important lighting control changes in the upcoming code as well as recommended solutions that meet these requirements.
Lighting Control Provisions Changes
Additional Code Changes
Illinois made one amendment to the 2018 IECC in the Electrical Power and Lighting Systems section (C405.1). The amendment establishes light efficacy requirements for dwelling units that do not follow the residential code. In these cases, no less than 90 percent of the light in these dwelling units shall have lamps with efficacy of 65 lumens/Watt or more or light fixtures with efficacy of 55 lumens/Watt or more.
