As of late huge crowds have been visiting the NY-Engineers.Com website in search of HVAC Engineering in the Chicago area. This is due primarily due to the reputation we have develop in this kind of work. With that said, many general contractors from Green Oaks to Bloomington, IL, are not aware that New York Engineers is also a top contender for anyone looking for HVAC Company near Chicago, Illinois.

The search for energy-efficient buildings involves energy-efficient HVAC system design. This can include systems for architectural enclosure, domestic water heating, lighting, HVAC, and vertical transportation. The loads for your HVAC systems can come primarily from five different bases including lighting (cooling), your building envelope (cooling and heating), ventilation (cooling and heating), equipment for program use (cooling) and occupancy (cooling).
The ventilation load is a function of either the machines needed in order to introduce it right into a space and control contaminant concentration or the number of persons which will use the place. In the vast majority of climates from the southwestern and eastern regions of the usa, to reduce outter ventilation helps you to save energy whenever the surface air is either warm and humid or very cold.
Manipulating the ventilation rate will be dependant upon occupancy which is referred to as a type of demand control ventilation. This can be a common type of energy conservation approach which is used for homes with irregular or dense occupancy. Having heating and cooling loads reduced as low as possible can be accomplished by making use of a high performance building envelope, occupancy sensors, and high performance lighting that employs daylight response of lighting controls.

Chicago HVAC Engineering services versus HVAC Techs

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

HVAC engineers are definitely the individuals who oversee setting up of air cooling systems for both residential and commercial buildings. They spend a lot of their day in offices doing higher level supervision and planning of installations nonetheless they do also go to job sites every once in awhile.

In comparison, HVAC technicians in Chicago tend to do more of the hands-on work  that deals with repair and maintenance. A HVAC tech may work with or for an engineer to complete some of the installation task, particularly for smaller jobs. On the whole HVAC techs do far more travel and may even spend lots of time identifying leaks, changing filters, doing recharges or getting rid of old and outdated systems that utilize old refrigerants.

HVAC engineers might have the ability to make more decisions about systems that are employed, and so they would be the individuals who would offer assistance with one of the most sensible refrigerants and which systems would work best with a much bigger building. In the trade, there exists some conflict between ‘the suits’ and ‘the ones which get their hands dirty’, but the two jobs do require a great knowledge of how air conditioner works. Lately huge crowds have been browsing the NY Engineers website searching for things like HVAC Supply House Chicago. With that said, the focus 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 Value Engineering Engineering services.

How MEP Engineers Explain Radiant Floor Heating and Its Benefits

MEP Firm Definition

Radiant floor heating consists of delivering heat through the existing floor surface, as opposed to using air ducts or baseboard heaters. The upfront cost of radiant floor heating is generally higher than that of other systems, since it is necessary for MEP engineers to install hot water piping or electrical wiring under the floor. However, this is compensated by improved comfort and energy efficiency.

According to the US Department of Energy, space heating is the highest energy expense in American households and represents around 45% of energy bills on average. Therefore, any improvements to heating performance and efficiency can yield an attractive return on investment.

How MEP Engineers Classify Radiant Floor Heating Systems

Most radiant floor heating systems are either hydronic, which rely on hot water piping; or electric, which use wiring or conductive mats under the floor. Air-heated installations also exist, but they suffer from a very low efficiency without offering any significant advantages. Radiant floor heating systems can also be classified based on their construction:

  • In wet installations, hydronic piping or electrical wiring is embedded directly in a concrete floor, or any other solid mass than can hold and emit large amounts of heat. It is important to note that “wet installation” is not a literal term: the hot water stays inside hydronic piping, releasing only its heat.
  • In dry installations, on the other hand, piping and cables are installed in an empty space between floor layers or below the floor, but are not embedded.

Deciding which heat source and system construction to use is a matter of cost and benefit that should be analyzed by MEP engineers.

For example, an electric radiant heating system of dry construction will generally be the cheapest but least efficient option. On the other hand, an embedded hydronic system is likely to have the highest upfront cost but also the lowest operating cost.

Energy Sources for Radiant Floor Heating

The heat sources available depend on the type of heating system. Hydronic radiant heating is the most versatile option because any energy source capable of heating water is viable; the system can run with electricity, natural gas, oil, propane, biomass or solar radiation. Electric radiant heating systems are much more limited, since their design only allows resistance-based heating.

Hydronic Radiant Floor Heating

As previously stated, the main advantages of this configuration are versatility and energy efficiency. Homeowners with hydronic radiant heating can choose from a wide variety of energy sources:

  • Boilers: These can be fired by natural gas, propane, oil or biomass, allowing their owners to choose the cheapest option at their location. Electric resistance boilers can also be used, but their high operating cost negates the efficiency benefit of radiant heating.
  • Heat Pumps: They are a cost-effective alternative to electric resistance boilers. Although they also run with electricity, but can match the output of an equivalent resistance heater with just a fraction of the energy input. In many cases, heat pumps can compete with gas boilers due to their superior efficiency.
  • Solar Collectors: Water heated by a solar collector can be used directly in a hydronic radiant heating system. If the available solar radiation is not enough to meet the heating load completely, the system can be complemented with a boiler or heat pump. Solar collectors can achieve excellent results when hydronic piping is embedded in a concrete slab, since it essentially allows energy from the sun to be stored thermally for nighttime heating.

An engineering consultant or design firm can help you determine the best option for your home, depending on your needs and site conditions. For instance, solar collectors are not viable if your rooftop has shading issues, and gas boilers can be very expensive to install if your property lacks a chimney or service entrance of enough capacity.

Another advantage of hydronic heating systems is that a central heating unit can be used for both water and space heating, consolidating two building systems and reducing their total cost.

Electric Radiant Floor Heating

This system configuration is characterized by a simple and cheap installation, but also a very high operating cost. No central boiler or heating unit is required: electric current is carried by wiring, and heat is generated locally. This type of system can be cost-effective when electricity rates are low and heating is used for only a few months each year, but this is not always the case.

Some electric radiant heating systems use conductive mats instead of wiring. The basic operating principle is the same, but heat distribution is improved.

Comfort and Health Advantages of Radiant Floor Heating

Radiant floor heating systems offer comfort and health benefits that apply regardless of the energy source and system construction.

Improved Comfort

Radiant heating systems operate without blowers and ducts, creating a uniform heat distribution throughout indoor spaces. Heat is radiated from the floor, and then distributed by natural air convection. This eliminates some issues that are common in forced-air systems and cause discomfort:

  • Uneven heat distribution
  • Noisy ducts
  • Draftiness

Health and Air Quality Benefits

Another advantage of radiant floor heating systems is that they can’t distribute allergens, volatile organic compounds (VOCs) or airborne germs because there is no forced air circulation. In addition, the ventilation system becomes independent from heating and can be designed specifically for indoor air quality.

Disadvantages of Radiant Floor Heating

As in all engineering decisions, radiant floor heating is not free from limitations: it generally comes with a higher price tag, and responds more slowly than other types of heating systems.

The cost of radiant floor heating can be very high in existing buildings, since it is necessary to embed a new system within the existing floor. The installation is even more expensive if an embedded system will be used, since it is necessary to pour a new concrete slab. Radiant floor heating is much more affordable in new construction, where floor installation costs are already part of the project baseline and it is only necessary to add one extra element.

Another disadvantage of radiant floor heating systems is that they take longer to heat an indoor space, compared with forced-air systems. However, this can be easily compensated with automation: smart thermostat can be configured to preheat rooms when the lowest hourly electricity rates are being applied, saving energy in the process!

General Recommendations for Radiant Floor Heating Systems

The choice of construction materials is very important when dealing with radiant floor heating. The Department of Energy recommends the use of ceramic tiles instead of wood, since ceramic can hold and emit heat more effectively. On the other hand, wood is essentially a form of insulation and it reduces system efficiency. Another disadvantage of wood floors is that they can crack in response to temperature changes.

Another recommendation offered by MEP engineers, which applies not only for radiant floor heating but for any HVAC upgrade, is to improve the building envelope before sizing the new equipment. This way, heating and cooling loads are reduced and the new equipment can be sized smaller, increasing the energy-saving potential.
