Available for free download on the Tate and Upsite Technologies website, the paper discusses the importance of including air-sealing grommets in the design of a new data center. According to the paper, air-sealing grommets rarely are installed at the same time as the raised floor during construction of a new data center. In fact, in many cases the grommets are forgotten even after construction is complete and the facility is up and running. This can be a costly mistake, with the potential to reduce the capacity of the data center and increase cooling costs.
