The possibility of a building burnt down due to fire is actually a sight that no one wants to enjoy. That is why fire protection engineers are hired before a building or apartment is built. When you are wondering who needs fire protection engineer, then this first name that you ought to know may be the architect of the building. Much like an architect is vital to ensure that the design of the property is perfect and protected from all ends; a fire protection engineer ensures that the property remains safe and secure from possible odds of fire.

Getting fast response from the firefighting professionals is alright but wouldn’t it be great if a fire never happened? You need to imagine “what if” as an alternative to going through the horrendous experience of the building being on fire. Fire protection engineers glance at the model of the construction first and then ma the escape routes to be used in a fire. Additionally, they are responsible for connecting many fire protection items inside and outside the structure. Water hoses and pipes linked to the main water supply, and checking the fitness of the fire extinguishers are a few of the duties which the fire protection engineer carries out if they are hired.

Difference Between Ashburn Chicago Fire Sprinkler Tech versus Protection Engineers

The Society of Fire Protection Engineers includes a precise concept of Fire Technology versus Protection Engineers. The two positions demand a solid education in fire technology and experience as a firefighter typically.

The engineers use principles to utilize systems and methods setups in several buildings that help protect people and things from harm during fires. Engineers analyze possibilities of where biggest fire hazards lie and where to implement protection such as sprinklers. They make certain that the utilization of structures as well as any materials in them are designed to keep dangers to a minimum.

Engineers will likely oversee the connection and repair of alarm systems, smoke detectors, and definately will carry out investigations of fires after one occurs. This assists them avert such incidences from occurring in the foreseeable future.

This sort of title employs scientific principles to help you enhance the safety of individuals in homes and offices. A fire technician works to do the testing and maintenance of the systems which were arranged and outlined with the engineers.

These folks should also hold the best education and firefighting training to function within the field. They may work to aid install sprinklers and fire alarm systems nonetheless they tend not to make the layout of the systems just like the engineers do. Even with all of this information you would like additional information about fire protection engineering services in Ashburn Chicago by New York Engineers you should stop by at our blog.

Architectural Engineers Detail Ventilation System Configurations

Value Engineering Examples In Construction

Human activity generates a broad range of compounds that become dangerous in high-enough concentrations, and pollutants from outdoor sources can also degrade indoor air quality. Architectural engineers are often charged with the job of preventing this from occurring as much as possible.

Ventilation systems keep these substances at low levels by constantly renewing indoor air, and they also contribute to keeping moisture within the range of 30 to 60 percent as recommended by ASHRAE. Without ventilation, it would not be possible to keep indoor environments comfortable and healthy.

Natural ventilation relies on wind currents, outdoor temperature and other weather conditions to supply fresh air. The advantage of natural ventilation is that it comes for free, and in new buildings it is possible to optimize architectural design to maximize its effects. However, natural ventilation is uncontrollable, and generally insufficient to fully meet the requirements of modern buildings.

Normally, to meet ASHRAE standards and local building codes, mechanical ventilation must be deployed. Depending on their configuration, whole-house ventilation systems can be classified into three main types:

  • Exhaust ventilation systems, which only use extractor fans.
  • Supply ventilation systems, which only use injector fans.
  • Balanced ventilation systems, which use both injector and extractor fans.

Balanced systems can be enhanced with energy-recovery ventilation, a technology that exchanges energy between the supply and exhaust airflows to maximize performance and minimize the overall running cost of the system.

Exhaust Ventilation Systems

As implied by their name, exhaust ventilation systems only deploy extractor fans. When the system starts to run, it creates a negative pressurization effect in occupied spaces, drawing in fresh outdoor air to renew that which is exhausted. It is important to note, however, that exhaust ventilation is not possible in air-tight buildings, since outdoor air must be allowed to leak in. If the building envelope has been tightened with caulking and weather stripping, exhaust ventilation must be complemented with intake vents.

Exhaust ventilation systems have a single set of fans and ducts, which makes them affordable while reducing their installation time and cost. Energy expenses are relatively low because there is only one set of fans in operation, and maintenance is simplified as well. The system layout can be designed to target specific areas where pollutants are generated, ensuring they are removed before they spread indoors.

Exhaust ventilation generally achieves the best results in cold and dry climates, where outdoor air does not require dehumidification. It is not recommended for tropical and mixed climates, because warm and humid outdoor air is drawn in without control, driving up cooling and dehumidification expenses. Also, keep in mind that depressurization draws air from all surrounding spaces, with little control over pollutant content. In general, architectural engineers recommend exhaust ventilation for cold weather, and when outdoor air pollution is low.

Another risk of exhaust ventilation is backdraft, which occurs when a combustion-based appliance suddenly draws in a lot of air, potentially causing a flashover. Since exhaust ventilation causes negative pressurization and does not control air supply, there is an increased chance of backdraft.

Supply Ventilation Systems

Supply ventilation only uses injector fans, pressurizing rooms and causing indoor air to leak out constantly. The main advantage of supply ventilation is control, since outdoor air can be filtered, humidified or dried as needed. In addition, the pressurization effect prevents the inflow of pollutants from surrounding spaces or from outdoors.

Another benefit of supply ventilation is that it eliminates the risk of backdraft from combustion appliances due to positive pressurization. Installation, operation and maintenance expenses are also reduced thanks to the simple system configuration.

Supply ventilation is better suited for tropical or mixed climate conditions, where dehumidification and filtering are often required. This configuration tends to cause trouble in cold weather, since the pressurization effect can cause condensation of indoor air humidity, leading to moisture accumulation and its common side-effects: furniture damage and the proliferation of mold, bacteria and dust mites.

Balanced Ventilation Systems

A balanced ventilation system is the result of combining exhaust and supply ventilation: both airflows can be controlled, providing the benefits of both system configurations. Of course, this comes at a higher installation and operation cost, since there are now two sets of fans and ducts.

Balanced ventilation is suitable for all weather conditions, and airflows can be adjusted to provide any pressurization effect as required – positive, negative or neutral. The recommended locations for each set of ducts are the following:

  • Supply ducts should focus on areas where occupants spend most of their time, including living rooms and bedrooms. This ensures that these areas always have a supply of fresh and clean air.
  • Exhaust ducts should focus on areas where moisture and humidity are released frequently, such as kitchens, bathrooms, laundries and boiler rooms.

Of course, it is possible to install supply and exhaust rooms for every room, but system costs are increased significantly. With the approach presented above, system costs are optimized without compromising performance.

Energy-Recovery Ventilation: Architectural Engineers Improve the
Efficiency of Balanced Ventilation

Energy-recovery ventilation consists on exchanging energy between the supply and exhaust air, so that overall HVAC costs are minimized. These systems can be classified into two main types:

  • Heat-Recovery Ventilation (HRV)systems only exchange heat between the supply and exhaust airflows.
  • Enthalpy-Recovery Ventilation (ERV)systems exchange both heat and moisture.

Summer Operation

In the summer, outdoor air typically requires cooling and dehumidification. However, when air is exhausted, it is still cooler and drier than the supply air; therefore, a part of the energy used for cooling and dehumidification is lost.

  • The use of a heat exchanger (HRV) can improve energy efficiency: the exhaust air is used to precool the supply air without mixing both airstreams.
  • If an ERV system is used, moisture is also transferred from the supply air to the exhaust air, further improving air-conditioning efficiency because there is less moisture to remove.

Winter Operation

During the winter, HVAC needs are reversed because outdoor air typically requires heating and humidification. The operating principle of HRV and ERV is the same, but the direction in which heat and humidity are transferred is inverted.

  • The exhaust air is warmer, and the heat exchanger captures a part of that thermal energy to preheat the supply air.
  • If ERV is used, moisture is also retrieved from the exhaust air and provided to the supply air.

General Recommendations for HRV and ERV

It is important to note that HRV and ERV systems are significantly more complex than the ventilation systems presented before. They can only be installed and serviced by qualified personnel, which increases their cost of ownership. Compared with a basic balanced ventilation system, HRV and ERV systems have a higher running cost, but overall HVAC expenses are reduced.

HRV and ERV systems increase in effectiveness where temperature  and moisture extremes are reached during the summer or winter, or when heating fuel costs are high. Their benefits are diminished under moderate weather conditions, where the added running cost may be higher than the savings achieved – balanced ventilation is a better alternative in these cases.

Spot Ventilation: A Complement for Whole-House Ventilation

Spot ventilation consists on using exhaust fans to extract pollutants and humidity at the room where they are released, preventing them from being spread throughout other indoor spaces. In residential settings, spot ventilation is most commonly used in bathrooms and kitchens to meet the minimum exhaust air levels established in both the area mechanical codes and ASHRAE standards:

  • Bathrooms require 50 cfm of intermittent ventilation or 20 cfm of continuous ventilation.
  • Kitchens require 100 cfm or intermittent ventilation or 25 cfm of continuous ventilation.

Spot ventilation can be a great complement for supply ventilation systems, removing pollutants from key areas. This combination provides many of the benefits of a balanced ventilation system without having to install a full set of exhaust fans and ducts. According to experienced architectural engineers, the only disadvantage of this combination is that HRV and ERV systems are unfeasible, since there is no point where heat or moisture can be exchanged between airflows.
