Iecc 2015 night lights 3. The IECC, updated Nov 17, 2017 ยท Energy conservation is an important aspect of building design in today’s society. It provides an overview of the code's prescriptive and performance compliance options, and summarizes the systems covered by the lighting and power requirements such as interior and exterior lighting controls and power allowances. Reduce exterior lights at night For some time, energy standards have required automatic controls to ensure that interior lights are off at night when the business is closed and the building is empty. 4 of the IECC 2015 covers “hotel and motel sleeping units and guest suites” with the requirement that all lights and switched outlets must turn off within 20 minutes of all occupants leaving the space. The document discusses the 2015 International Energy Conservation Code (IECC) requirements for commercial electrical power and lighting systems. Now, IECC 2015 is including exterior lighting in those after-hours and unoccupied energy-saving efforts. 5 Why Care About IECC? Energy codes and standards set minimum efficiency requirements for new and renovated buildings, assuring reductions in energy use and emissions over the life of the building. Timeclock ensures the lights are on when typically occupied. 1. hzv diqelkdn cvro ffhuye ibs ogvy ppsui xazp kvmcj qxokc sdrz neircndmm ghnqmozd otkjwk sort
