International Energy Conservation Code Training – April 2018
A series of free statewide training sessions were offered to government employees, architects, engineers, contractors, and others in the design and construction community. The training sessions covered energy efficient design concepts and code requirements for both residential and commercial buildings. Updated checklists were provided and new requirements were highlighted.
