8-13-13 Washington State Energy Code:

The 2012 Version of the Washington State Energy Code was adopted by jurisdictions in Washington state on July 1, 2013.  The new code requires 1.5 energy credits for homes in the 1500 to 5000 square feet range.  There are several options for meeting this requirement including the use of high efficiency HVAC and water heating equipment.  The use of a heat pump electric hot water heater with an efficiency rating of 2.0 is an efficient way of meeting the new code requirement and using clean technology.
