This document discusses liquid cooling considerations for data centers. It introduces The Green Grid, an organization that advocates for optimizing data center efficiency. The Green Grid has developed several metrics and tools to measure efficiency, including an updated liquid cooling total cost of ownership calculator. The calculator allows users to simulate liquid cooling costs based on location, accounting for climate data, potential data center designs, energy usage, and total cost of ownership over time. Examples are provided comparing potential data center designs and costs for locations in Seattle and Taiwan.
