Conventional commuter trains are generally limited to a top speed of 60 miles per hour. The train speed is limited by the track condition, curvature, and elevation changes. It takes a lot of energy to move that big, heavy equipment up and down the track. Additionally, the train must overcome rolling resistance between the train wheels and the track to get to higher speeds.
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.
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.
The DOE compliance deadline for pumps is coming up on January 27, 2020. While it may seem like this date is far into the future, think about this: New Year's Day 2019 is only 166 days away. Time does fly, doesn't it?
In the U.S. in the 1970s, neighborhoods and highways looked much different than they do today. It wasn’t unusual to see people in the car in front of you chuck bottles and full bags of road-trip trash out of their windows. Highways were littered with the remnants of lunches and snacks from passengers who didn’t think twice about trying to find an actual trash receptacle.
Design engineers work hard to design comfort systems that serve the goals of the building and, ultimately, achieve that ever-elusive dream of perfect comfort for building occupants. But after all the meetings are over and the bids are submitted, design is sometimes sacrificed for initial equipment costs. Or, a design is scrapped altogether because the building owner is frightened of initial costs. However, according to a recent article written by AEGIS, the lifetime cost breakdown of ownership of something as simple as an electric motor is boiled down to this:
