EES employees like to play as hard as we work! A couple of us wanted to experience life in the fast lane, so we took a trip to Dover motor Speedway for a Nascar experience.

Keeping the Creep out of your BMS

Posted by Daniel F Luna, P. E. on Mar 5, 2024 10:57:11 AM

Schedules are at the very heart of most modern Building Management Systems (BMS). They tell when a particular tenant space or common space is to be “on” or “off”.   Clearly, tailoring the “on” time to match as closely as possible the actual occupancy is the way to shave off waste.

Dehumidification Optimizations Using Waste Heat Recovery

Posted by Daniel F Luna, P. E. on Oct 23, 2023 1:53:00 PM

Save on energy resources by utilizing a heat-recovery chiller or DX compressors

Running an air handler in “dehumidification” mode tends to be a resource hog. First, you are using a lot of chilled water to *squeeze* the ever-living-moisture out of the air, then you have to reheat it to make the air temperature comfortable. A double expenditure of energy: cooling and heating.

Optimizing BMS Air-Side Economizers for Colder Weather: Harnessing Nature for Chilled Water Cost Savings

Posted by Daniel F Luna, P. E. on Oct 12, 2023 2:43:44 PM

Utilizing air-side economizers during the cooler seasons can significantly reduce chilled water costs by leveraging outside air for cooling, offering substantial energy savings for businesses in temperate climates.

As we slip into fall, our thoughts turn to pumpkin spice.  Our air-side economizers – a duct and damper arrangement with a control system that enables the heating, ventilation, and air conditioning (HVAC) system – however, think about saving chilled water costs.  If we can lower load for the chiller, we can save money due to less energy being used. If the outside air is cool and dry enough, we can open an economizer and let nature do the job instead of using the chilled water coil.  It also usually has the benefit of changing the air more quickly than during the winter or summer seasons.  

Less chilled water pumping also lowers the energy needed to move the water around. We control the differential pressure of the chilled water by slowing down the chilled water pump via a variable frequency drive (VFD), and less load raises the differential pressure.  The tower also must do less work because there is less heat rejected out to it, so the fans run slower.  This saves tower make-up water as well: less evaporation, less water needed.

Get to Know the Team: Bruce Marson

Different jobs require different types of disciplines.  Not just in the academic sense, but in the practical sense.   Ask any good musician how they got that way and they will tell you practice, patience and tenacity will get you where you want to be.  Similar traits that transfer over to the controls engineering world.  There is a reason that the back of EES' business card reads “experience, something you get right after you need it”.

Twenty-Two Years Ago Today

Posted by Bruce Marson on Sep 11, 2023 6:00:00 AM

On September 11, 2001, EES lost a good client. We had the control system on the central chilled water plant at the World Trade Center. EES was scheduled for service at the site that day, but was postponed due to a hang-up on the purchase order, fortunately our visit was re-scheduled, to never. We knew many of the operators, some of whom stayed at their posts when the building went down.
