Repair Versus Replace HVAC Equipment?
Preventive maintenance keeps HVAC systems running, but don’t forget to take the long view to plan for 2018.
Ultraviolet Germicidal Irradiation Improves IAQ
With millions of travelers passing through LAX annually, facility management at the world’s seventh busiest airport chose UVGI, or UV-C, technology.
Concerned With Poor IAQ?
A facility’s indoor air quality affects occupant health as well as energy efficiency. Take steps to mitigate negative impacts.
Reduce Energy Use, And Save Water
An emerging focus on the water energy nexus—the interplay of these resources in building systems—holds promise for conservation.
Derive Savings From Demand Control Ventilation
Among energy conservation measures, DCV provides significant energy reductions for the operation of HVAC systems.
Refrigerants With Low Global Warming Potential
Regulations and overall concern for the environment is driving research to identify effective refrigerant alternatives with low GWP.
Chiller Data: Connected Or Not?
For proactive chiller maintenance and operation, connectivity provides facility staff with quick access to equipment conditions.
The HVAC Factor: Sound Attenuation For Exposed Ductwork
Minimizing unwanted noise throughout a facility calls for examining HVAC ductwork system components, and their operation.
The HVAC Factor: New Life For An Aging Chiller Plant
Completed in December 2014, this renovation project serves as an example of how a historic utility plant can be improved to address significant elements and concerns.
The HVAC Factor: Executive View of Preventive Maintenance
A summary report of HVAC service provides insight that is useful to repair and replace plans.
The HVAC Factor: Insulation For Chilled Water Piping
With hot, humid climates as the focus, several types of chilled water pipe insulation were field tested.
HVAC Factor: Data Center Operations
Power Usage Effectiveness (PUE) is a metric for tracking systems efficiency. But, there’s more to measure in the data center.
The HVAC Factor: Systems Get A Break
At the University of Baltimore, a new facility features passive heating and cooling, and natural ventilation.
The HVAC Factor: Hybrid Operating Rooms
As with traditional operating rooms, HVAC systems are crucial to the success of these emerging healthcare spaces.
The HVAC Factor: Double Duty
HVAC systems may be the key to providing occupants with mobile connectivity in a facility.
The HVAC Factor: Keeping Cool, Safely
For facilities that handle hazardous items, indoor air quality and comfort are challenges.
The HVAC Factor: Standard Maintenance
The recently updated ACR standard from NADCA advises facility managers, and their contractors, on best practices.
The HVAC Factor: Keeping Steady With Geothermal
Temperature control was crucial for a research facility in North Carolina. From the October 2013 issue.
The HVAC Factor: Spiral Round Ductwork
As an alternative to rectangular ducting, this approach is a more efficient delivery system when conditions are suitable. From the August 2013 issue.
The HVAC Factor: Wireless Thermostat Conversion
In Oakland, CA, an office building reduced energy use (and occupant complaints) with a retrofit to its pneumatic equipment. From the June 2013 issue.
