'H ' The 137,000 square foot NREL RSF expansion will complement the original building, a commercial prototype for high performance large-scale office buildings. The expansion project will seek LEED certification at the Platinum level and a net zero energy design. Improving on the success of the RSF the new wing will be delivered for $13 less per square foot, and is expected to achieve a 13% savings in overall energy performance, compared to the original building. The expansion is scheduled for completion in October 2011 and will offer space for 500 additional NREL and DOE staff.
