1) A study used computational fluid dynamics (CFD) modeling to compare worker heat stress in a traditional raised floor data center layout versus a modern enclosed hot aisle layout.
2) The CFD analysis found that average hot aisle temperatures were about 8°F higher in the enclosed hot aisle layout, but calculated wet bulb globe temperatures (WBGT) remained below Occupational Safety and Health Administration (OSHA) and International Organization for Standardization (ISO) exposure limits in both layouts.
3) While the enclosed hot aisle layout increased heat stress slightly by about 1°F WBGT, heat stress levels in both layouts were determined to pose minimal health concerns according to OSHA and ISO guidelines.
The Use of Ceiling Ducted Air Containment in Data CentersSchneider Electric
Ducting hot IT-equipment exhaust to a drop ceiling can be an effective air management strategy, improving the reliability and energy efficiency of a data center. Typical approaches include ducting either individual racks or entire hot aisles and may be passive (ducting only) or active (include fans). This paper examines available ducting options and explains how such systems should be deployed and operated. Practical cooling limits are established and best-practice recommendations are provided.
Row-based data center cooling is normally regarded as
a “cold air supply” architecture that uses row-based
coolers. However, row-based cooling is actually a “hot
air capture” architecture that neutralizes hot air from IT
equipment before it has a chance to mix with the
surrounding air in the room. This paper discusses
common misconceptions aboutrow-based cooling,
explains how row-based cooling removes hot air, and
describes key design attributes that maximize the
effectiveness of this approach.
The segmentation of data centers into alternating hot and cold aisles is an established best practice. A number of manufacturers are taking this premise of airflow separation a step further by marketing "containment" solutions. By containing the hot or cold aisle, the air paths have little chance to mix, presenting data center operators with both reliability and efficiency gains.

High Efficiency Indirect Air Economizer Based Cooling for Data CentersSchneider Electric
Of the various economizer (free cooling) modes for data centers, using fresh air is often viewed as the most energy efficient approach. However, this paper shows how indirect air economizer-based cooling produces similar or better energy savings while eliminating risks posed when outside fresh air is allowed directly into the IT space.
Implementing Hot and Cold Air Containment in Existing Data CentersSchneider Electric
Containment solutions can eliminate hot spots and provide energy savings over traditional uncontained data center designs. The best containment solution for an existing facility will depend on the constraints of the facility. While ducted hot aisle containment is preferred for highest efficiency, cold aisle containment tends to be easier and more cost effective for facilities with existing raised floor air distribution. This presentation investigates the constraints, reviews all available containment methods, and provides recommendations for determining the best containment approach.

Retrofitting EC plug fans - An energy efficiency drive that can cost more tha...Robert Schmidt
Energy efficiency is a key driver for many upgrades in legacy Data Centers. Improvements in fan technology have meant that upgrading the fans in an old Data Center air conditioner can yield massive savings, many times that of the cost of the work. However, what is often forgotten is that, because fans are the devices that actually distribute cooling throughout the Data Center, changing their behavior will change the behavior of the Data Center itself. Changes to cooling distribution throughout the Data Center will have a knock-on effect on deployment and capacity planning. The new cooling distribution provided by the new, energy efficient fans, must therefore be evaluated before the decision to proceed is made. The only way to do this is through simulation.

Practical Options for Deploying IT Equipment in Small Server Rooms and Branch...Schneider Electric
Small server rooms and branch offices are typically unorganized, unsecure, hot, unmonitored, and space constrained. These conditions can lead to system downtime or, at the very least, lead to “close calls” that get management’s attention. Practical experience with these problems reveals a short list of effective methods to improve the availability of IT operations within small server rooms and branch offices. This paper discusses making realistic improvements to power, cooling, racks, physical security, monitoring, and lighting. The focus of this paper is on small server rooms and branch offices with up to 10kW of IT load.
Virtualization and Cloud Computing: Optimized Power, Cooling, and Management ...Schneider Electric
IT virtualization, the engine behind cloud computing, can have significant consequences on the data center physical infrastructure (DCPI). Higher power densities that often result can challenge the cooling capabilities of an existing system. Reduced overall energy consumption that typically results from physical server consolidation may actually worsen the data center’s power usage effectiveness (PUE). Dynamic loads that vary in time and location may heighten the risk of downtime if rack-level power and cooling health are not understood and considered. Finally, the fault-tolerant nature of a highly virtualized environment could raise questions about the level of redundancy required in the physical infrastructure. These particular effects of virtualization are discussed and possible solutions or methods for dealing with them are offered.
The green data center has moved from theoretical to the realistic, with IT leaders being challenged to construct new data centers (or retrofits the existing one) with energy saving features, sustainable materials and other environmental efficiencies in mind.
This project deals with the effects that are caused by the data center. How severe these effects are and how to overcome these. The measures that has been provided are not only in constructional point of view but also focusing on other dimensions.
Proactively Managing Your Data Center Infrastructurekimotte
Attached is the presentation from our Proactively Manage Data Center Infrastructure Webinar - to view the webinar with audio, go here:http://blog.eecnet.com/proactive-manage-data-center/
One of the most critical aspects of traditional data center infrastructure is cooling system optimization and planning. When a subset of the system is physically relocated closer to the end user, as described in the Edge Data Center (EDC) concept, a solution to provide a data center-like environment for high-power equipment in public places such as office buildings, shopping centers, school campuses, event arenas, and wireless cell sites will be required.
Eliminating Data Center Hot Spots: An Approach for Identifying and Correcting Lost Air
Data center cooling is a hot topic. But, when you consider the challenges associated with cooling the latest generation servers, the growing cost of infrastructure equipment, and the risks associated with data center hot spots brought on by high-density clusters and premature hardware failure, it's easy to understand the focus.

CPD Presentation Evaporative cooling in data centresColt UK
Data centres that use evaporative cooling can cut their energy bills by up to 80% compared to conventional cooling methods!
The specifications for the environmental operating conditions of IT equipment used in data centres have recently been revised, opening the way to evaporative cooling in such buildings. Evaporative cooling can provide a highly effective solution, with low installation and running costs, minimal maintenance requirements and quiet operation.
This seminar covers:
• Revisions to the specifications for the environmental operating conditions of IT equipment in data centres
• Options for cooling in a data centre
• Implementing evaporative cooling in a data centre.
