The Century Project involved an exciting and innovative renovation to the Space Needle, Seattle’s premier tourist attraction. The renovation took place over 500 feet above ground level and included over 170 tons of glass. The Century Project included seismic upgrades, mechanical upgrades, and a new viewing deck called The Loupe, in addition to renovations. EEI provided LEED Cx for the mechanical and electrical systems involved in the renovation. 

The Loupe is the world’s first and only revolving glass floor, and it weighs over 37 tons with ten layers of glass. Replacement of the top layer of glass is intentionally easy to allow for future repairs and replacements. During the project, the construction team created a temporary work platform so that the upper viewing deck remained open for the 1.3 million tourists who visit the Space Needle annually. 

Cx uncovered several concerns with the MEP equipment, which EEI brought to the design and construction teams’ attention. Together we resolved each of these issues, including scope gaps, new-to-existing system integration problems, and pressure differentials between restaurant and kitchen. Overall, our efforts increased occupant comfort, equipment and controls operation, and energy savings.
