Improving electrical energy performance is an important consideration in the design, construction and operation of any data center. This paper proposes a holistic methodology in achieving energy performance and capital expenditure (Cap X) savings. While achieving these savings, the challenge is to maintain or increase reliability, in other words, decreasing risk. Most data center energy projects usually focus on a single goal, not considering the holistic effect of increased risk or decreased reliability. When these non-tangible omissions become apparent, the energy performance aspect frequently becomes marginalized or canceled.

Integrated Waterside Economizer Operation for Data Center Central Chiller Plants
This white paper explores the effectiveness of using an Integrated Water Side Economizer (IWSE), which differs from the traditional water side economizer, as it pipes a Heat Exchanger (HX) in series with the chillers. Energy savings can be recognized in a water cooled chiller plant by using this low- cost solution, which involves the addition of a few automated valves and piping alterations that enable the plant to capture a substantial amount of “partial cooling” hours during the shoulder seasons (Fall/Spring). Consequently, the KW input requirements of the chiller are reduced.

An Electrical Win-Win Solution and Best Practice
In Critical Facilities, the electrical load on the critical (UPS output) bus is a continuous load that rarely changes (except to increase!). A 100%-rated circuit breaker will carry 100% of its rating continuously, but an 80%-rated circuit breaker will carry only 80% of its rating. Why are 80%-rated circuit breakers specified for continuous loads? By specifying 100%-rated circuit breakers we can reduce first cost (CAPEX) and increase availability.
