How to Reduce Electricity Costs Ahead of Rate Increases
Posted by Sara Lewis on in Engineering, Energy Solutions
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 […]

Comfort Issues: Get the Correct Correction
Posted by Bob Schneider on in Facility Operations
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 […]

Closed Loop Water Treatment
Posted by Bob Schneider on in Engineering
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 […]

What’s a Watt? (And Other Electrical Fundamentals)
Posted by Mike Ruff on in Fundamentals
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 […]

Central Air Adds LEED Points
Posted by Bob Schneider on in Energy Solutions
Developers are showing increasing interest in central air conditioning for many reasons. Ideally suited for multi, multi-use dense, vertical developments, central air conditioning reduces energy use by 30–50%, helps earn LEED points, eliminates rooftop condenser “farms” that preclude green roof options and become maintenance nightmares, and generates revenue. Central air conditioning systems have smaller footprints […]
