In April 2008, Governor David Paterson decided to renovate the existing Javits building with a severely revised budget of $465 million. The renovation, started in 2010, was led by design team FXFOWLE Epstein, whose redesign of the Javits Center's interior focused on upgrading organization and efficiency, as well as occupant comfort. The more transparent curtain wall, less opaque skylight systems, and light gray paint on the space frame have dramatically transformed the voluminous public spaces. New mechanical systems have improved the indoor air quality, reduced ambient noise, and significantly saved on energy consumption. The diamond-patterned Tuscan red terrazzo of the original floor has been replaced with soft tones of gray terrazzo. A new high-performance curtain wall has simplified and lightened the aesthetics of the original façade by changing the façade's module from to . This allowed for the introduction of more transparent glass with minimal structurally glazed mullions. Solid stainless steel panels replaced the opaque portions of glass to better express the building's functionality. The roof of the new expansion was also made "green" by the presence of a garden in the new wing's roof. The renovation was completed in November 2013. The expansion was meant to retain old tenants coming back annually, such as the New York Boat Show.
