What LEED Gold Certification Gets You

I just read an article in the May 2018 ASHRAE JOURNAL about Discover Elementary School in Arlington, Va. designed by VMDO Architects; it is currently the largest zero energy elementary school built in the US. It’s interesting to compare its size, cost, and “sustainable” qualities with Cornell’s LEED gold-certified Milstein Hall, the architecture building designed by OMA and Rem Koolhaas. Both are two-story academic buildings.

  Size (sq. ft.) Cost ($ millions) OFF-SITE Energy USED
Discover 97,000 32.3 None
Milstein 50,000 60+ Lots

So, in a nutshell, Milstein Hall is half the size, twice the cost,* and barely meets minimum ASHRAE energy standards,** while the Arlington school actually returns energy to the grid.

*To be clear, the Arlington school is half the cost and twice the size; in other words, its cost per square foot is approximately 25% that of Milstein Hall.

**Cornell’s stated goal (see my video) since 2008 is for new buildings “to use 30% less energy than current energy standards and strive towards 50% less energy.” Milstein Hall’s energy model projects a whopping 2% energy reduction compared to this minimum standard.
