If you shudder when you think about ice building up on the roof and gutter of a commercial building, you are not alone. Here in the Carolinas, ice can be a tricky foe in the winter months.
Pumps are serious business in the world of commercial building. Engineers spend vast numbers of hours reviewing usage requirements so that the correct pumps are specified, purchased and installed for building and system needs. However, you may hear months, or even years, later that the building owner is experiencing problems with that same pump you painstakingly selected.
We are huge advocates of utilizing VFDs to control AC motors in most instances. It isn't often that we need to run a pump motor at full speed, so we can reduce our energy consumption (lower costs) while being a little kinder to our motors by installing VFDs in our systems. Rarely in life do we encounter anything that is flawless, however, and VFDs are no exception. They do lower our operating costs and can increase system performance, but they also create shaft voltage.
Halloween is here, the scariest night of the year! We all know that HVAC and plumbing engineers are brave, strong, and essentially fearless. After all, they design systems out of thin air, easily troubleshoot annoying problems that haunt other mortals, and relentlessly stick to their guns when specifications are called into question. Engineers are basically the John Wayne of the professional world. They just don't scare easily.
Let’s face it, we live in a world of instantaneous gratification. We want it now. We want it now and we don’t want to wait. We want it now and we don’t want to go any further than our finger tips to get it. In today’s IoT world, everything is immediate.
Continuing education is a critical component of our jobs these days. Technology is changing so rapidly, it's virtually (no pun intended) impossible to keep up with revised best practices, new equipment, and updated regulations.
energy (n): Power derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines.
Our obsession with energy, how to harness it and how to use it efficiently is not a new thing. After humans first warmed themselves with the sun, they eventually discovered fire. Early humans used wood fires to cook food and keep warm. Modern humans still do it in home fireplaces, wood-burning stoves and during camping adventures.
Innovation doesn't come easy these days. We're all so busy just getting things done day after day that it's tough to spend the extra time and thought energy into creating better technology, business practices and equipment. Innovation, however, is a critical piece in offering solutions that improve the customer experience.
Hospital HVAC systems work overtime. Every day of the year, around the clock, they must be working properly for patient comfort, maintaining air quality and keeping airborne disease transmission at bay. And, since HAIs (Hospital-acquired Infections) are a hot topic among hospital administrators and the news media, system designers and facilities managers are increasingly pressured to ensure that systems are chosen, installed and maintained with care.
