1. Sustainable Trends for Data
Center Facilities
• Increasing energy efficiencies and reducing other
resource use and impact on the environment,
• Increased operating temperatures to equipment
with goal of eliminating compressor based cooling
• Use and increased use of various software and
controls for monitoring, control and simulation of
Data Centers, including DCIM, BIM ,Virtual
Memory Managers and CFD.
2. Increasing Energy and
Resource Efficiencies
• Use of Variable speed equipment to match load
changes including ECM fan motors.
• Consolidate and concentrate heat sources for increasing
efficiencies of heat rejection equipment, including hot
and cold isle containment, and high Delta T fluid and
pumped refrigerant based systems.
• Higher voltages in equipment, eliminating one or more
transformers.
• Increasing computations per watt at the server.
• RoHAS complient IT Equipment.
3. Increasing Energy and
Resource Efficiencies
• Use of harvested water such as Rain and Condensate to
reduce energy required from infrastructure, reduce water
treatment costs and increase efficiency of air cooled
equipment.
• Use of Photo V and Thermal V for reducing energy
required from regional power plants
• Use of evaporative media and spray systems for non-
electric humidification and compressor less cooling
• Larger more efficient pieces of mechanical equip.
• Extensive use of natural cooling sources.
4. Increasing Operating
Temperatures for
Air cooled equipment
• ASHRAE TC9.9 new classes for recommended and
allowable air temperatures for DataCom equipment
• Increased temperatures create greater heat transfer
rates and more efficient heat rejection equipment.
• Increased temperatures create greater use and
opportunity for free cooling form air and water side
economizers
5. Increasing Operating
Temperatures for
Water cooled equipment
• ASHRAE TC9.9 new classes for water cooled DataCom
equipment
• Tremendous power and energy reduction for water vs.
air cooled equipment.
• Increased temperatures create greater use and
opportunity for free cooling from water side economizers
and heat recovery up to over 115 deg F.
• Water cooled equipment expected to replace air
cooled equipment
6. Data Center/Building
Information Management and VMM
• Measuring and Benchmarking of resources allows for
determining efficiency increasing equipment
utilization, planning and refresh upgrades for most
efficient deployment.
• Virtual memory managers and similar software
optimizes server utilization including shutting down
idle servers. and equipment.
7. Computational Fluid Dynamics
Modeling
•Determine proper airflow and
reduce short circuiting of
rejected heat, even in contained
systems.
•Predict data center cool and hot
spots based on design
specifications and temperatures
entering equipment.
•Predict failure modes
