At the recent ASPE Convention and Expo, I visited friends at the Leonard booth. I was invited to see their new electronic thermostatic mixing valves. Simply stated, it was cool. The adjustment of the hot water temperature setting was quick and easy on the basic model. The other models can connect to the building management system, or even your cell phone.
There is no doubt that issues with natural resources and conservation of energy will continue to make daily news headlines. The concerns around exploiting our depletable resources and sensitivity on the battered environment have led society to find alternative and better ways to use and manage the energy that is available to us, principally in the use of renewable resources such as absorbing and storing solar energy.
All too many times a bid is turned in only to be told, “We need to look at VE options.” There are plenty of mechanical units that can be downgraded, architectural features that can be sacrificed, or peel back every division to see what can possibly be optimized for that extra dollar.
Previously only common in high-performance computing (HPC), a growing number of data centers are adopting liquid cooling. The driver — an increasing number of high-density racks being deployed to support artificial intelligence and other latency-sensitive and processing-intensive business applications.
Gary Hayden is a man of many talents. A licensed Professional Engineer in Virginia and eight other states, the 63-year-old’s career has taken him from product development to design and finally, the implementation of radiant and hydronic systems.
One of the best things about hydronic heating systems is that it’s easy to integrate some method of domestic water heating. This combination has been used for decades in systems where a boiler was the sole heat source. It’s also possible when a heat pump serves as the heat source.
I am often asked, “How do you remove the stranglehold that the union has on the Uniform Plumbing Code and Uniform Mechanical Code?” My answer is always the same — you outvote them at the Annual Conference at the end of the code change cycle.
Whether driven by rigorous state and local regulatory mandates, or simply the desire to live more sustainably, the demand for a smaller carbon footprint and greater energy efficiency is growing in both the residential and commercial building and renovation markets.
