Lately huge crowds have been taking a look at the NY Engineers site looking for MEP Engineering in Chicago. That is due because of the reputation we have built in this kind of work. With that said, a lot of general contractors from Lake Bluff to Schaumburg, IL, are not aware that NY Engineers is also a top contender for anyone looking for HVAC Chicago

The search for power efficient buildings involves energy-efficient HVAC system design. This will likely include systems for HVAC, lighting, architectural enclosure, domestic water heating, and vertical transportation. The loads for your HVAC systems should 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 purpose of either the instruments necessary so as to introduce it in to a space and control contaminant concentration or the quantity of persons who will occupy the place. In the vast majority of climates inside the southwestern and eastern regions of the US, to minimize outter air-flow can save energy whenever the surface air is either humid and warm or very cold.
Manipulating the ventilation rate will probably be dependant on occupancy which is referred to as a variety of demand control ventilation. This really is a common type of energy conservation tatic that is utilized for spaces with occasional or heavy occupancy. Having cooling and heating loads dropped to a minimum can be carried out by utilizing a higher performance building envelope, occupancy sensors, and high performance lighting that exploits daylight response of lighting controls.

Chicago HVAC Engineers vs HVAC Technicians

If you have ever considered the difference between a HVAC Technician versus HVAC Technicians, then please read on:

HVAC engineers are definitely the people who supervise installing of air conditioning systems both for residential and commercial buildings. They spend lots of their work in offices doing advanced level organization and planning of installations nonetheless they do also see job sites from time to time.

But, HVAC technicians in Chicago usually do more of the hands-on work with maintenance and repair. A HVAC tech may work together with an engineer to accomplish some of the installation task, especially on smaller jobs. Generally speaking HVAC techs do a lot more travel and may spend time and effort changing filters, identifying leaks, doing recharges or decommissioning old and outdated systems that utilize old refrigerants.

HVAC engineers may have the opportunity to make more decisions about systems that are being used, and they are definitely the people that would offer advice about by far the most sensible refrigerants and which systems would work best with a much bigger building. In the trade, there is certainly some competition between ‘the suits’ and ‘the ones which get their hands dirty’, but both jobs require a good understanding of how air conditioning works. As of late many people have been checking out the NY-Engineers.Com website searching for HVAC West Chicago. Nevertheless, the goal of our organization is to become the number one choice for anyone looking for a HVAC Chicago and or any of our other services including Architectural Engineering Engineering services. We ask that everybody looking for more details about our Heating Cooling Air Conditioning Furnace (HVAC) Engineering Firm in Chicago Illinois takes a look at our blog…

A Construction Engineers Guide to Selecting the Right Type of Electrical Raceway: Metallic Conduit Options

Fire Protection Engineering UMD

Electrical conductors are subject to stringent installation requirements, established in the NFPA National Electrical Code and the NYC Electrical Code, to which construction engineers must abide. There are many logical reasons for this.

A conductor in the open is vulnerable to physical damage, and at the same time it represents a high risk of electric shock or fire. Therefore, conductors must have both electrical insulation and physical protection; unless a conductor is armored or sheathed, physical protection is typically provided by electrical conduit.

The different types of electrical conduit in the market differ in terms of material used and flexibility: conduit can be either metallic or non-metallic, as well as rigid or flexible. Although each type is intended for different applications, there is some overlap between approved uses. Therefore, design engineers must often choose between many valid options for a given application. Sizing is very important: undersized conductors cannot accomplish their function, but oversized conductors represent a waste of capital.

This article will provide an overview of the main types of metallic electrical conduit and their applications. Keep in mind this is a general guide, not a replacement for NFPA and NYC codes. The technical requirements explained here are very general – make sure you check the applicable codes before specifying conduit in any project. There are five main types of metallic conduit, which are summarized in the following table:

AbbreviationFull Name
EMT
RMC
IMC
FMC
LFMC
Electrical Metallic Tubing
Rigid Metal Conduit
Intermediate Metal Conduit
Flexible Metal Conduit
Liquidtight Flexible Metal Conduit

Electrical Metallic Tubing (EMT)

EMT is a lightweight but rigid metallic raceway option. If offers less mechanical protection compared with IMC and RMC, but it has the advantage of being easy to bend, which is beneficial when construction engineers must build the electrical raceway around obstacles or corners. The most commonly used EMT materials are galvanized steel and aluminium.

Since EMT is not normally threaded at its ends, fittings use perpendicular screws or threaded compression unions. Set-screw fittings are cheaper, but compression fittings offer a tighter connection.

Electrical codes do not allow EMT in applications where electrical raceway is exposed to significant physical damage or corrosion, or in occupancies classified as hazardous locations.

Rigid Metal Conduit (RMC)

RMC is the heavy-duty option, with the thickest walls among all metallic conduit options. This type of conduit is the standard choice for demanding environments, offering both mechanical and chemical resistance. RMC is normally made from galvanized steel, stainless steel, red brass or aluminium. All types are suitable for corrosive environments, but additional protection may be required in the case of aluminium RMC.

RMC offers far greater mechanical resistance than EMT, but this comes with a much higher price tag. Working with RMC also involves more technical complexity, requiring specialized equipment for cutting and threading.

Intermediate Metal Conduit (IMC)

As implied by its name, IMC is the intermediate option, thicker than EMT but thinner than RMC. However, IMC uses a high-strength steel alloy to offer physical protection comparable to that of RMC, in spite of the reduced wall thickness. IMC can be used in the same applications where RMC is allowed, and it only has one limitation: while RMC trade sizes range from ½” to 6”, IMC only goes from ½” to 4”. Therefore, you must use RMC in heavy-duty applications where the specified conduit size exceeds 4”.

It is important to note that, although IMC is thinner than RMC, the external diameter is the same for both types of conduit. As a result, IMC has slightly more internal space to handle conductors.

Flexible Metal Conduit (FMC) and Liquidtight Flexible Metal Conduit (LFMC)

In the electrical trade, FMC is normally called “greenfield” or “flex”. The body of FMC uses an interlocked steel spiral to offer decent mechanical protection but also flexibility. FMC is typically used when raceway ends require flexibility for connection, or when a connection to vibrating equipment that may cause fatigue failure in a rigid connection. LFMC is basically FMC with a liquid-tight coating, typically made from a thermoplastic material.

Additional Recommendations from Construction Engineers

Keep in mind that conduit diameter is determined by conductor diameter, which in turn is determined by the load on the circuit. Therefore, energy efficiency measures can lead to conductor and conduit savings in new constructions. The savings from using a smaller conductor and conduit diameter may not be noticeable for a single branch circuit, but the savings add up in a large project such as a high-rise building.

MEP design software is also a very powerful tool to reduce conductor and conduit costs. When circuit routes are specified as short as possible, material requirements are reduced, along with the associated man-hours from associated construction engineers and others.
