Zero-energy buildings (ZEBs) have enormous potential to transform the way buildings use energy. Large private commercial property owners are interested in developing ZEBs to meet corporate goals. Federal governmetal agencies, along with many state and local entities, are starting to move toward zero-energy targets.
However, there's no established consensus on what constitutes a ZEB. We need a widely accepted definition - and process to measure achievement - so that governments, utilities, and private entitites can actually recognize and incentivize ZEBs.
