Design Guidance for Cybersecuring Facility-Related Control Systems
In September 2016, the Department of Defense (DoD) published Unified Facility Criteria (UFC) 4-010-06, Cybersecurity of Facility-Related Control Systems. Although the UFC was written for architects, engineers, systems integrators, and operators who plan, construct, and operate DoD control systems, it can be used for the design of virtually any control system.

Cooling

Low-Temperature Chilled-Water Plants
In 1998, ASHRAE Journal published an article explaining how operating supply chilled-water-temperature setpoint influences the annual energy use of a chilled-water plant. The article concluded one is better off maximizing chiller efficiency by using a higher chilled-water temperature. This article revisits that conclusion using modern chiller-plant design and other revised assumptions using computer energy modeling.

Hybrid Cooling Modes in Chillers
How hybrid cooling modes in chillers maximize efficiency year-round, automatically.

Data Centers

Data-Center Reliability and Efficiency: Do You Have All of Your Bases Covered?
As information technology has flourished, data centers have become a crucial, even mission-critical, part of plant operations. As such, they are much larger, with significant electrical loads that produce more parasitic heat and the need for more cooling. Energy usage and efficiency have grown to be major concerns. This article provides practical advice for reliable and efficient data-center operations.

Engineering Green Buildings

Improve Energy Efficiency, Thermal Comfort, and Performance of HVAC Systems With CFD in the Cloud
Factors limiting the use of computational fluid dynamics (CFD) in the design of HVAC systems include lengthy modeling and setup time, expensive software licenses, and extensive training requirements. These challenges are being addressed by a new generation of cloud-based software that enables engineers to access leading-edge CFD capabilities from the cloud on an as-needed basis in a fraction of the time and cost involved in using conventional CFD tools. This article will explore how cloud-based CFD software can be used to optimize several different types of HVAC systems.

Managing Your Facilities

Fan-Coil Renovations: Repair, Replace, or Refurbish?

It is inevitable that over time your facility’s HVAC will break down or require an upgrade. If you have an aging facility combined with a limited budget, like many building owners, you must make the decision whether to replace, repair, or refurbish your HVAC system. In the case of fan-coil systems, each option includes pros and cons. This article will examine each.
