The pursuit of energy efficient buildings involves power efficient HVAC system design. This may include systems for architectural enclosure, domestic water heating, lighting, HVAC, and vertical transportation. The loads for the HVAC systems will come primarily from five different places including lighting (cooling), your building envelope (cooling and heating), ventilation (cooling and heating), equipment for program use (cooling) and occupancy (cooling).
The ventilation load will certainly be a function of either the mechanisms required so as to introduce it into a space and control contaminant concentration or the amount of individuals that may be in the space. In the vast majority of climates within the southwestern and eastern parts of the united states, to minimize outside air-flow will save energy whenever the outer air is either warm and humid or very cold.
Manipulating the ventilation rate will likely be determined by occupancy which is known as a type of demand control ventilation. This is a common type of energy conservation tatic which is used for buildings with occasional or heavy occupancy. Having heating and cooling loads reduced as low as possible can be accomplished through the use of a higher performance building envelope, occupancy sensors, and performance lighting that uses daylight response of lighting controls.

Chicago HVAC Engineering services versus HVAC Technicians

If you have ever wondered about the difference between a HVAC Engineers vs HVAC Engineers, then please read on:

HVAC engineers are the individuals who watch over installing of air-con systems for both residential and commercial buildings. They spend lots of their work in offices doing higher level organization and planning of installations nonetheless they do also go to job sites from time to time.

On the other hand, HVAC technicians usually do more of the hands-on work with maintenance and repair. A HVAC technician may assist an engineer to do a number of the installation task, especially on smaller jobs. Generally speaking HVAC technicians do far more travel and might spend a lot of time identifying leaks, changing filters, doing recharges or decommissioning old and outdated systems that utilize old refrigerants.

HVAC engineers might have the chance to make more decisions about systems that are used, plus they will be the people that would offer advice about probably the most sensible refrigerants and which systems would best suit a larger building. In the industry, there is some challenge between ‘the suits’ and ‘the ones which get their hands dirty’, but the two jobs require an effective understanding of how air conditioner is proven to work. In recent times huge crowds have been visiting the NY-Engineers.Com website searching for things like HVAC Maintenance Chicago. With that said, the focus of our organization is to become the number one choice for anyone looking for a HVAC Companies in Chicago and or any of our other services including Value Engineering Engineering services. We ask that everyone searching for more info about our Heating & Air Conditioning (HVAC) Engineering Firm in Chicago Illinois visits at our CAD to Revit Modeling blog!

A Look at Cable Bus, Courtesy of Electrical Engineers

Value Engineering Process Steps

Cable installation is one of the activities that demand the most man-hours from electrical engineers in building construction and renovation projects. The use of a reliable wire management system makes the installation simpler and safer, and cable bus is very useful when dealing with medium-voltage conductors. The NFPA 70 National Electrical Code dedicates Chapter 3 to Wiring Methods and Materials, including raceway systems for conductors above 600V.

Cable bus is used with conductors much larger than those delivering power to lighting fixtures, power outlets and HVAC equipment in your home or office. The rated voltage exceeds 600V, while the current range is typically from 1,000A to 8,000A. There are other raceway options for large conductors, such as busway and cable tray, but cable bus offers a middle point that brings advantages of both.

Wireways for Conductors Above 600V

When dealing with conductors and their raceway systems, the NEC establishes additional requirements when rated voltage exceeds 600V in a given application:

  • Conductors above 600V must not share enclosures and wireways with circuits below 600V, unless a specific code article makes an exception.
  • Circuits above 600V must use suitable enclosures to prevent accidental contact or physical damage.
  • The smallest bend radius allowed is 8 times the diameter for unshielded conductors, and 12 times the diameter for shielded conductors. Multi-conductor cables are limited to 12 times the individual conductor diameter or 7 times the total diameter, whichever is less.
  • Metallic raceways must be protected from induction heating.
  • Consider there are differences between the requirements for above-ground and buried conductors.

To compare busway, cable bus and cable tray, first we must define each type of raceway, as they are understood by electrical engineers:

RACEWAY TYPEDESCRIPTION
BuswayGrounded metal enclosure, which comes with factory-installed conductors. These can be bare or insulated; made from aluminum or copper; and shaped as bars, rods or tubes.
Cable busAssembly of insulated conductors that includes fittings and terminations, all enclosed in a ventilated metallic housing for protection. Unlike busway, which is fully factory-assembled, cable bus is partially assembled at the project site. Cable bus is designed to withstand the magnetic forces present during faults, reliably holding conductors in place.
Cable trayA structural assembly with multiple sections and fittings, designed to fasten wiring or smaller raceways.

Ask Electrical Engineers: What Advantages Does Cable Bus Offer?

Cable bus is characterized by its safety, since it is built to withstand the magnetic forces that occur when one of the conductors carries a fault current. Cable bus also offers a middle ground between the fully prefabricated busway and the site-assembled cable tray.

Cable bus also saves on supporting fixtures, by using some prefabricated components while retaining flexibility in conductor layout. In a few words, cable bus offers a rigid construction like busway, while having wiring flexibility and open ventilated construction like cable tray. Some common applications of bus duct include connections between the following equipment:

  • Generatorsand transformers
  • Generators and switchgear
  • Transformers and switchgear
  • Different switchgear units
  • Switchgear to motor control centers (MCC)
  • MCCs and high horsepower motors

Electrical safety is important in any installation, but additional protection measures are required as voltage level increases, since accidents have a greater potential to cause damage. By working with qualified electrical engineers you can ensure your installation meets the NFPA 70 National Electrical Code, in addition to local standards.
