New state construction must exceed the energy conservation provisions of the Oregon State building code by 20% or more. In addition, the 2007 Oregon Legislature passed HB2620, which requires that public entities spend 1.5% of the total contract price of a public improvement contract for new construction or major renovation of a public building on solar energy technology. The SEED guidelines were updated October 1, 2010, to include changes made to the 2010 Oregon Energy Efficiency Specialty Code.
