high performance objectives
design, analysis, documentation
Transformation of a 512,400 sf, 18-
story, 1974 office building into a LEED
Platinum cornerstone of GSA’s green
building portfolio.
BUDGET: $141,000,000
Upgrade building systems:Seismic, MEP, telecom, fire protection
EUI target: 34-36 kBtu/yr/sf
Update work environment:Improve daylighting, electric lighting, air quality
Improve accessibility

MECHANICAL SYSTEMS RADIANT ADVANTAGES •Net rentable area increase / more
efficient floor plate
•Ceiling height / fewer beampenetrations
•Expanded comfort range
•Reduced operations and maintenance
•Improved indoor air quality
•Less air / reduced fan power
•Quick to respond to changes
•Future flexibility

Reeds provide avg. 50%
shading
Shading reduces the heat gain on
the building minimizing the energy
needed for cooling.

occupant feedback• OVERALL OCCUPANT SATISFACTION
– good, but averaging masks localized responses
• RESULTS FILTERING - PRIORITIES
– thermal comfort
– daylight and glare
• FILTER PARAMETERS
– solar orientation
– building level, upper levels (10-17) vs. lower (3-9)
• IMPLEMENTING SOLUTIONS
