How Are RESNET Standards Developed?

Any interested party can submit proposals for new or revised standards provisions. Proposals will be reviewed by the Standards Management Board to determine if a proposed new standard fits within the scope of standards RESNET wants to develop. If the proposal is accepted, a New Work Item (NWI) be will assigned to the Standards Development Committee (SDC) for development.

Proposed standards provisions are posted on the RESNET website for public comment for a minimum of 30 days, where public comments will be reconciled by the appropriate RESNET Standing Committee, with a recommendation to the RESNET Board of Directors.
