Recently Hundreds of individuals have been stopping by our website looking for Construction Engineering in Chicago. That is due primarily due to the following we have develop in this kind of work. Nevertheless, a lot of general contractors from Bolingbrook to Belvidere, IL, are not aware that New York Engineers is also a top contender for anyone in search of HVAC Chicago!

The search for energy efficient buildings involves cost effective HVAC system design. This may 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), the 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 instruments required to be able to introduce it into a space and control contaminant concentration or the number of persons that may occupy the place. In virtually all climates within the southwestern and eastern regions of america, to minimize outter ventilation helps you to save energy whenever the

outside air is either humid and warm or very cold.
Controlling the ventilation rate will be dependant upon occupancy which is called a variety of demand control ventilation. This really is a common type of energy conservation plan that is utilized for rooms with intermittent or heavy occupancy. Having cooling and heating loads dropped to a minimum can be accomplished through the use of a high performance building envelope, occupancy sensors, and high performance lighting that uses daylight response of lighting controls.

Chicago HVAC Engineers versus HVAC Technicians

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

HVAC engineers are definitely the people that supervise setting up of air conditioner systems for residential and commercial buildings. They spend plenty of their time in offices doing advanced level supervision and planning of installations but they do also see job sites from time to time.

But, HVAC technicians in Chicago often do more of the hands-on work  that deals with repair and maintenance. A HVAC technician may work with or for an engineer to do a number of the installation task, especially on smaller jobs. Generally HVAC technicians do much more travel and could spend lots of time changing filters, identifying leaks, doing recharges or decommissioning old and outdated systems which use old refrigerants.

HVAC engineers could possibly have the opportunity to make more decisions about systems that are being used, and they would be the individuals who would offer advice about probably the most sensible refrigerants and which systems would best suit a greater building. In the industry, there exists some competition between ‘the suits’ and ‘the ones that get their hands dirty’, but the two jobs require a great understanding of how air cooling is proven to work. Lately huge crowds have been reading our sites looking for things like Four Seasons HVAC Chicago Reviews. Nevertheless, the focus of our firm is to become the to go to firm for those searching for a HVAC Chicago and or any of our other services including Sprinkler System Engineering services. We ask that those looking for additional details about our Air Conditioning, Heating & Cooling (HVAC) Engineering Firm in Chicago Illinois stops by at our blog…

Understanding Value Engineering in Upgrading LED Lighting Systems: Lamp Replacements, Retrofits and Fixture Replacements

Value Engineering Architecture

LED lighting upgrades can be classified into three broad types based on how much the existing installation is modified: lamp replacements, retrofits and fixture replacements. You can normally achieve higher performance by upgrading more lighting system components, but the project cost is also increased. However, governments and utility companies may introduce rebate programs for energy-efficient lighting, and an expensive project can end up being high value engineering after a good rebate.

Like with any energy efficiency measure, a technical and financial analysis of the project is highly recommended before proceeding. This way, you can prioritize the specific upgrades that yield the highest return on investment. Although many factors determine project performance, the following tend to be the most relevant:

  • Upgrading lighting systems with long operating schedules first is recommended. Keep in mind that energy savings are the product of power saved and hours of use. The most efficient LED bulb in the market will not save much energy if the fixture where you install it is rarely used.
  • Lighting upgrades inside air-conditioned and refrigerated spaces provide two types of savings: a direct reduction in lighting power, and also a reduction of the amount of heat handled by cooling equipment.
  • The project achieves better results when the technology gap between the proposed and the existing lighting system is broader. For example, upgrading from incandescent to LED lighting yields more savings that upgrading from fluorescent, even if the final project consumes the same power in both cases.

This article will provide a brief overview of the main types of lighting upgrades, along with general recommendations for each case.

Value Engineering: Lamp Replacements

The simplest type of lighting upgrade is replacing existing bulbs with equivalent versions having better performance. This type of lighting upgrade can be performed quickly and for a relatively low cost, making it a value engineering option for companies who want to minimize disruption or who have a limited budget for energy efficiency projects.

Replacement lamps must also be selected with suitable lighting properties, depending on each application. They should deliver sufficient illuminance (lumens per square meter) while having the right color temperature (CCT) and the highest possible color rendering index (CRI) that meets the project budget.

  • Low CCT values (warm colors) work better when you want to create a relaxing environment, while high CCT values (cool colors) are recommended when visibility and awareness are important – in sports venues and manufacturing applications, for example.
  • On the other hand, the CRI is not specific for each application; a higher color rendition is always better but generally costs more.

Lighting designers use software such as DIALux to simulate the specified luminaires and fixtures, ensuring they deliver adequate lighting for their intended application.

If you are looking for replacement lamps, make sure you purchase products with the blue ENERGY STAR logo, which ensures high performance and intensive laboratory testing. In commercial and industrial applications you may find the DLC label instead (Design Lights Consortium). Both programs have very strict labeling requirements, so their respective logos indicate high quality and performance. They are mutually exclusive for most product categories, so don’t look for replacement lamps with both labels.

Retrofits

A retrofit is one step above a lamp replacement in complexity: existing lighting fixtures are reused, but with significant changes to their internal configuration.

  • An example of a retrofit would be taking a strip fixture with two 8-foot T12 fluorescent tubes and modifying it to use two parallel sets of 4-foot LED tubes.
  • This process involves bypassing or removing the ballast, changing the lamp bases, and adding additional bases halfway through the fixture body.
  • If the LED tubes specified use an external driver, it must be mounted inside the fixture as well. Drivers are similar to ballasts,but exclusive for LED and with aadditional lightingcontrol

Some retrofits stick to a similar topology as the lamps replaced, like the example above where 8-foot fluorescent tubes are replaced with 4-foot LED tubes. However, some lighting providers change the configuration completely; for example, there are rectangular retrofit kits with light engines that do not resemble tubes at all, intended for existing 2×4 or 2×2 fixtures. Retrofits kits are also commonly used with decorative fixtures, to preserve the fixture body while improving lighting performance.

Basically, a retrofit is intermediate between a lamp replacement and a fixture replacement. The fixture is partially modified and the light source is changed completely, but the fixture body is preserved. Many internal components are replaced or rewired, but not necessarily all of them.

Fixture Replacements

With this type of lighting upgrade the existing fixtures are removed completely, including the housing. A complete fixture replacement is the most expensive lighting upgrade, but it also tends to deliver the highest energy savings: integral LED fixtures are designed with an internal geometry that maximizes lighting delivered to working planes. On the other hand, with relamps and retrofits you are subject to the optical performance of the existing fixture.

Rebate programs tend to offer higher incentives for full fixture replacements, compared with relamps and retrofits.

Conclusion

There are many options available if you plan to upgrade the lighting system in your building. In general, LED lighting is a cost-effective investment due to its superior energy efficiency and long service life, but LED products are characterized by diversity and too many options can cause confusion. Get a professional lighting assessment to find the most promising lighting upgrades.

The incentive per fixture may not seem much, but consider that a large building can have thousands of fixtures. You can start saving electricity and money earlier by acting fast and pursuing the highest value engineering for your desired outcome.
