In 2011, IBA and Viridian Energy & Environmental merged their specialized service offerings to form Vidaris. As building envelope designs and mechanical systems were becoming more complex, the two companies recognized that it was an opportunity, more so a necessity, for them to be able to provide a holistic approach to these closely related disciplines for their clients. Deep technical knowledge, a long proven track record, reputation, and a sophisticated analytical approach would allow Vidaris to provide a level of service second to none.
Vidaris evaluated the thermal modeling simulations to select optimized building envelope components as they relate to energy efficiency and code compliance. Vidaris witnessed the curtain wall fabrication and monitored the installation. As sustainability consultants, Vidaris developed the overall green/LEED thrust. This direction was subsequently used for the three other Silverstein towers of the World Trade Center complex. Vidaris has also been analyzing the energy use for the mega-project.
