Leaders at the Virginia Department of Motor Vehicles are expecting recent upgrades to the state DMV building in Richmond, VA, to reduce energy consumption by 36% and save $284,000 a year.
While energy efficiency remains at the forefront of trends impacting the HVACR industry, it’s not only efficiency that the industry — and country — needs to be thinking about.
From setting up node addresses to the nuances of lead and lag pump operation, explore the opportunities for tailored, more efficient performance and increased redundancy.
In an effort to improve energy efficiency for commercial buildings, ASHRAE, IES, ANSI, and the DOE have been working diligently to increase the stringency of state energy codes.
Who actually specified that motor? Did they keep the entire system in mind or were they simply specifying one component at a time? And will that spec require over-speeding the motor?
The available LEED credits and most obvious energy-saving possibilities are one thing. The potential for a ripple effect of system-wide savings by deploying VFDs as part of better overall monitoring are another.
Motor problem documentation, grease compatability, fits for bearings … these are just three aspects covered in ANSI/EASA AR100. Whether you maintain your own motors or simply own them and require proper maintenance, understanding the concerns, resources, and recommendations of AR100 will encourage proper repairs and longer service life.
There’s nothing simple about the design, construction, and maintenance of a hospital’s protective environment and airborne infection isolation spaces. However, if you pay careful attention to recommended ventilation and filtration strategies for the rooms and adjacent areas, you can handle the pressure (so to speak) and deliver a healing environment.
