![]() Therefore choosing whether to use IECC or ASHRAE needs to be thought of from both an Electrical and Mechanical perspective. Electrical and Mechanical systems that remain largely unchanged do not need to adhere to new guidelines. As I understand it, you can use either code in either situation, it's just that IECC has more expensive mechanical requirements while ASHRAE has more expensive electrical requirements. Typically, in remodel situations, office buildings tend to follow the ASHRAE 90.1 because changes to the mechanical systems can be too intrusive and expensive. The IECC tends to steer towards new construction and has more stringent standards for mechanical systems while ASHRAE 90.1 steers more towards remodels but focuses more on lighting controls. The Engineer of record is allowed to choose the code that best suits them. There are currently two different standards for the MN Energy Code, IECC 2012 and ASHRAE 90.1. ![]() Motor rated high cycle relay with zero cross triggering. ![]() Easy Regulatory Compliance with Avi-on Plug Load Control Switched AC Power Output 20A Switched AC output for full circuit plug load controls. ![]() The MN Energy Code is a new set of codes that focus on lighting and plug load control. Complies with Title 24, ASHRAE 90.1, Washington State, and New York State requirements for plug load controllers. ![]()
