Minimizing refrigerant leaks has always been an important goal for owners/operators, system designers, manufacturers, and service technicians of commercial refrigeration equipment. 

This article explores how to refine and enhance the efficiency of pumping to match precisely to load, balancing the interests of pump experts — favoring primary-secondary piping — with those on the “boiler side” who prefer a variable speed/variable flow approach.  

The O’Connor Building was designed by SOM with a deliberate focus on fostering collaboration in four key research areas: advanced materials, quantum science and computing, urban research and innovation, and the energy transition.

Electrification of existing buildings may or may not require an upgrade of the electrical service size.
 

2024 can be a great year for professionals if they embrace the new opportunities that are available to them and “look back to look forward.”

Master planning today will help you avoid future failure.

There is also something called “Monday Syndrome,” which refers to fatigue, dizziness, chest tightness, abdominal distension, loss of appetite, body ache, inattention, and other symptoms often experienced on a Monday. Although it's often attributed to psychological factors, the reality is that poor IAQ can actually cause most of those symptoms.

Chiller performance and size no longer need to be at odds. The same advancements driving energy efficiency are also enabling reduced chiller footprints in both air- and water-cooled equipment.

Raising awareness about DCV, IAQ monitoring, and AI optimization can enhance indoor air quality and sustainability in nearly any type of building.
