More Renewable
More Renewable
Generation: NREL’s new
Research Support Facility
Innovation for Our Energy Future
6. The building will
achieve LEED
Platinum rating
but will use 50% less
energy th if it were
than
built to current
commercial codes
Innovation for Our Energy Future
7. The RSF will increase
NREL’s campus
square footage by
60% but increase
campus energy use
by only 6%
Innovation for Our Energy Future
8. The RSF’s highly
efficient green data
center will serve
the
entire laboratory
campus and be a
model for others
Innovation for Our Energy Future
9. Is a living laboratory
where researchers use
real-time
building
performance
data to study building
energy use.

10. The RSF is a prototype for the future of
p yp
large-scale, ultra-efficient buildings
It will change the way the commercial
building industry views energy efficient,
high performance office buildings…
The reality of ultra-high
efficiency buildings:
Doable, affordable.
Not a concept, but here
