As companies are looking for newer office that can accomdate their high-tech needs and growing environmental efforts, Larry A. Silverstein, chief executive officer of Silverstein Properties Inc., sees two of his new office buildings at Ground Zero the logical choice.

According to Bloomberg Business Week, “some 235 tenants have moved from midtown to downtown” since 2005. As newer buildings are constructed with high-tech and green accomdations in mind, it seems many more tenants might be moving into the neighborhood.

Conde Nast is one of those potential tenants, looking to lease a sizable amount of office space at 1 World Trade.
