This is the first part of the threepart Vendor Training Series on the Energize Denver requirements for buildings 5,00024,999 sq. ft. In this video, you will learn the details of the lighting requirements for buildings of this size, which is one of the compliance pathways for building owners. Lighting contractors and electricians will especially benefit from understanding these requirements, since buildings that choose this compliance pathway will need to certify that at least 90% of their lighting load is met with LEDs.
