Many buildings are located in developments, or on sites with underground electrical and tele/data/cable utilities. While the underground services eliminate unattractive overhead pole lines, cabling and transformers, the installation of utility company transformers presents challenges of a different sort. Utility company transformers are large, generally green in color, and can range from a small box […]
Sometimes, it can be difficult to understand changes on your electric bill and even harder to determine what you can do to bring monthly costs down. TES Engineering recently attended a seminar that discussed First Energy rate structures and the company’s planned impending rate increases. In this blog post, we hope to break down the […]
Many spaces on the same HVAC system experience comfort issues: Either it is too hot, too cold, or sometimes a mixture of the two. If a client asks you about this type of problem, airflows are likely to be the cause—but calling a contractor to perform an air balance isn’t the first step of the […]
In a central plant system, there are two types of water piping loops: closed and open. An open loop is from the chiller to the cooling tower. As the water flows through the tower, it is open to the atmosphere. Because of evaporation at the cooling tower, city water is introduced to replace the evaporated […]
Basic electrical calculations involve three parameters, volts, amps and watts. Volts Here in the United States, we design according to specific voltages provided by our utility companies. In residential construction, we often have 120/240V, single phase, 3-wire, while in commercial construction we typically have 120/208V, 3 phase, 4-wire or 277/480V, 3 phase, 4-wire (although older […]
