Rejuvenating Garage CO Safety Systems

Posted by Daniel F Luna, P. E. on Mar 24, 2023 1:59:49 PM

It has become common practice to build underground or under-building parking lots for facilities. Each structure requires a CO monitoring system that jumps in to action when the level of CO gas becomes too high. Every one of these systems requires periodic (semi-annual) calibration and testing to protect the patrons and the building owners.

Daylight Savings Time – Friend or Foe?

Sunday, March 12th, we'll 'spring forward' an hour on our clocks. Soon, Congress is going to vote to put to rest the yo-yoing of clocks twice a year.  If and when it does become law, we will be staying this way "forever." But is this a good or a bad thing?

Project Profile: What Is Old Is New Again

Blog post by Bruce Marson, President, Engineered Energy Solutions

I guess the old saying “what goes around, comes around” if you wait long enough, is true in the controls industry as well. We had for many years, a large telecommunications client for whom we had installed PLC-based building controls in the late eighties. The client was forward thinking in regards to the energy consumed by their 2.2 million square-foot R&D facility. Having the innovative corporate culture that fueled hundreds of patents per year, they recognized the rewards we were offering with our new (at the time) PLC-based energy control system. Back in the day, no one was applying PLCs to central utility plants and major air handling systems like we were and after a review of the numbers, they took a chance. After completing the installation, we saved them $500,000 per year with a return on investment in under two years.  When the project ultimately lead to the client winning an award from the State of New Jersey for energy management, we had a client for life.
