H Effi i L d tHow Efficiency Leads to More RenewableMore Renewable Generation: NREL’s new Research Support Facility


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


The RSF will increase NREL’s campus square footage by 60% but increase campus energy use by only 6%


The RSF’s highly efficient green dataefficient green data center will serve the entire laboratoryentire laboratory campus and be a model for others


Is a living laboratory where researchers usewhere researchers use real-time buildingbuilding performance data to study buildingdata to study building energy use.


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…
