A proven HVAC technology wordwide, Variable Refrigerant Flow (VRF) zoning systems are poised for dramatic growth in all areas of commercial construction because they provide precise zones control that can contribute toward the achievement of LEED certifications.
The future of pervasive device communication is envisioned to be so powerful that everyday devices will be able to identify each other's presence and role, and interact in a manner that benefits our way of life. Such communication-rich environments will lead to embedded computation abilities, where information can be collected by devices and sensors, and processed to generate an intelligent response and coordinated actions. This white paper focuses on the benefits of integrating devices with enterprise and business processes and the importance of having holistic visibility over operational data.
IP telephony and power over Ethernet (PoE) are driving the requirement for increasing uptime levels, power capacity, and the need for dedicated precision air conditioning across the network. High-availability environments, such as data centers and computer rooms, may have the power and cooling infrastructure in place to handle these changes, but in many cases, equipment rooms and wiring closets do not. This white paper provides specific guidance on ensuring proper power and cooling support for the Cisco routers and switches operating in network closets and equipment rooms.
This paper describes a new CFD-based modeling
capability and design methodology that overcomes the limitations of
conventional guidelines and traditional CFD-based approaches and is
effective at addressing equipment related cooling and efficiency
problems in the data center.
As computer manufacturers pack more and more processing power into smaller packages, the challenge of data center cooling becomes more complex - and more critical. New servers and communication switches generate as much as ten times the heat per square foot as systems manufactured just ten years ago.. This white paper describes the new strategies and technologies that must be implemented to provide the cooling high-density systems require for reliable operation.
This white paper describes a new approach to power distribution for high density server installations that saves floor space, simplifies power cabling, saves capital costs, reduces weight, and increases electrical efficiency.
While new technology advancements are helping
communities execute services faster and more efficiently, many local
governments are having trouble finding the funds to implement them.
According to Gartner Research, virtually all IT project investments
within local governments will undergo a value-for-money reassessment
beginning this year. Many will take advantage of the new economic
stimulus funds from the American Recovery & Reinvestment act. But
will the stimulus offer enough help?
This white paper addresses
how technology is now able to deliver meaningful ROI data and why a
well-planned implementation of technology initiatives will deliver the
strongest public value impact. The strategy is showcased in success
stories from two local governments who were able to serve their
constituents by making their communities more efficient, even when
financing looked impossible.
Water is used in a wide range of commercial
applications. Every day, businesses and facilities heat water to serve
the needs of their customers and patrons. While restaurants,
laundromats, hotels, and car washes all require very large amounts of
hot water to stay in business, nearly all companies rely on hot water
in one way or another. Each year, a significant portion of their
overhead is allotted to the fuel required to heat water, and everyday
that allotment becomes slightly larger. However, many do not realize
what they lose each year due to the negative by-products of heating
water such as lime scale buildup, which cause efficiency losses,
malfunctions, total equipment failure.
