The X-Factor: Y Should U Care?

Unprecedented vendor-neutral data has been brought down from the mountain on a digital tablet.

September 1, 2013

Unprecedented vendor-neutral data has been brought down from the mountain on a digital tablet. That’s helpful for data center designers, but applying a little thought and site-specific consideration can reveal the path to wisdom in areas like failure rate, noise, power draw versus temperatures, and more.

This project team left nothing to chance when it came to designing a five-story mixed-space facility for a Chicago gaming company. They also dealt a full hand of space-specific tactics: upgraded DX units, a dedicated variable-speed kitchen exhaust system, underfloor air, and better motors and drives improved the odds for efficiency. Pull the handle on this project story to get to the payoff.

Net Zero Near The River

A 70-structure campus at the top of the Mississippi has been in need of a serious retrofit. We join this major project in progress, studying not only the design selections but the tradeoffs and sacrifices along the way.

Smoke detection in data centers is critical, not only for life safety reasons, but also to reduce fire-related business interruption and property damage.

Plan For A Better BAS

In a campus environment over time, it’s not hard to lose control of the controls. When you tackle the situation for the long-term good, take time to create a master plan. Get a few tips on that here
