Innovation for Our Energy Future
The building will
LEEDachieve LEED Platinum rating
but will use 50% less energy th if itenergy than if it were built to current commercial codes
Innovation for Our Energy Future
The RSF will increase NREL’s campus square footage by 60% but increase campus energy use by only 6%
Innovation for Our Energy Future
The RSF’s highly efficient green dataefficient green data center will serve the entire laboratoryentire laboratory campus and be a model for others
Innovation for Our Energy Future
Is a living laboratory where researchers usewhere researchers use real-time buildingbuilding performance data to study buildingdata to study building energy use.
Innovation for Our Energy Future
The RSF is a prototype for the future of p yplarge-scale, ultra-efficient buildings
It will change the way the commercialIt will change the way the commercial building industry views energy efficient, high performance office buildings…
The reality of ultra-high efficiency buildings:efficiency buildings: Doable, affordable.Not a concept, but here p ,today
