Plumbing & Mechanical Engineer

This month of June, six months into 2023, is a great time to review the activities of Standards Development Organizations, or SDOS. These organizations develop standards through voluntary consensus processes for product performance and safety, services, processes, systems and personnel.

Those who evaluate the performance of HVAC source equipment such as boilers, furnaces and heat pumps have to work with a wide variety of acronyms. Some of them were spawned by government bureaucrats, mostly the U.S. Department of Energy (DOE). Others were created through a consensus process based on input from manufacturers and other industry stakeholders.

My last two columns discussed both chemical and non-chemical additives or technologies that I treat as “must consider” for plumbing engineers in their design practices to reduce the risk of Legionella bacteria developing in the domestic water system. As I mentioned, these topics might not be a code minimum requirement, but as an engineering community, we have a responsibility to uphold the health and safety of the public. Therefore, we should discuss these technologies with our clients for many different building types we come across in our design.

If you follow me on LinkedIn, you know I am passionate about advocating for plumbing engineers and designers. I have regularly written about the need for plumbing engineers, especially in solving our various water crises and improving our medical gas systems. The lesson is clear: plumbing systems are continually increasing in complexity.

Welcome to Spring 2023! Regardless of the temperature, I know spring is close when the male American Goldfinches start their molt from olive green to vibrant yellow. It is a beautiful sight to see and promises warmer days ahead.

Morris had me on the phone. It was 1974 and he was calling from Brooklyn, New York. I had a waxed handlebar mustache that year, and my workmates at the manufacturers’ rep were calling me Rollie Fingers because he was pitching for the Oakland Athletics in the World Series.

Over the years I’ve had opportunities to work with several architects. They’re interesting people who have the ability to meld art with building technology. Sometimes the result is more “art,” and sometimes it’s more “building.” In either case, their designs typically get handed off to engineers with the simple request: Figure out how to heat my creation…

Codes and standards are intended to provide a minimum level of protection for the public’s health, safety and welfare. And, generally, these documents accomplish that intended purpose in the urban/metropolitan areas of the United States. However, that may not be accurate when one gets into the rural or more isolated areas of the country.

April 2023. I don't know where the days and weeks have gone, but here we are again, PM Engineer readers. This time we'll discuss the important changes to the code development process in Canada!

Given the current upward trend and volatility of fossil fuel pricing, there’s renewed interest in heating using wood pellets. Federal incentives that currently cover 26% of some qualified equipment adds enticement toward purchasing pellet-burning stoves.
