As of late Hundreds of people have been taking a look at the NY-Engineers.Com website searching for HVAC Engineering near Chicago. This is due because of the following we have built in this types of projects. However, many builders from Burnham to Robbins, Illinois, don’t know that New York Engineers is also a top choice for anyone searching for HVAC Company in Chicago, IL!

The quest for cost effective buildings involves power efficient HVAC system design. This will likely include systems for domestic water heating, architectural enclosure, HVAC, lighting, and vertical transportation. The loads for your HVAC systems can come primarily from five different places including lighting (cooling), the construction envelope (cooling and heating), ventilation (cooling and heating), equipment for program use (cooling) and occupancy (cooling).
The ventilation load is a purpose of either the mechanisms required so as to introduce it in to a space and control contaminant concentration or the quantity of persons which will be in the space. In the majority of climates inside the southwestern and eastern regions of the united states, to lower outter air movement can save energy whenever the

outside air is either warm and humid or very cold.
Governing the ventilation rate will be dependant on occupancy which is called a form of demand control ventilation. This can be a common type of energy conservation policy that is utilized for homes with occasional or dense occupancy. Having heating and cooling loads reduced to a minimum can be achieved by utilizing an increased performance building envelope, occupancy sensors, and performance lighting that exploits daylight response of lighting controls.

Chicago HVAC Engineering services versus HVAC Techs

When you’ve ever wondered about the difference between a HVAC Technician vs HVAC Technicians, then continue reading:

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

But, HVAC technicians in Chicago tend to do more of the hands-on work with maintenance and repair. A HVAC tech may work with or for an engineer to complete a few of the installation work, particularly for smaller jobs. On the whole HVAC techs do much more travel and could spend time and effort changing filters, identifying leaks, doing recharges or getting rid of old and outdated systems that use old refrigerants.

HVAC engineers could possibly have the chance to make more decisions about systems that are employed, and they are the folks that would offer advice about by far the most sensible refrigerants and which systems would be perfect for a much bigger building. In the trade, there may be some conflict between ‘the suits’ and ‘the ones that get their hands dirty’, but both jobs do require a good knowledge of how air conditioner works. In recent times a lot of individuals have been crawling the NY Engineers site looking for HVAC Apprenticeship Chicago. However, the focus of our company is to become the top option for anyone seeking a HVAC Chicago and or any of our other services including Architectural Engineering Engineering services. We ask that anyone looking for additional details about our Air Conditioning, Heating & Cooling (HVAC) Engineering Firm in Chicago Illinois takes a look at our Electrical Engineers blog

Financial Analysis: Your Next Mechanical Engineering Project

Value Engineering Ppt

Basics of Financial Analysis for Engineering Projects

Mechanical engineering decisions have a significant impact on the total cost of owning a building: they influence the cost of new constructions and renovations, as well as operation and maintenance expenses in existing facilities. The most challenging decisions are normally those that raise some costs while reducing others; for example, using LED fixtures instead of fluorescent tubes raises the upfront cost of the lighting system, but drastically reduces energy and maintenance expenses in the long run.

If you are involved in engineering design or consulting, financial analysis is one of the most powerful complementary skills you can master. Financial analysis grants engineers and firms some distinctive advantages over competitors who only focus on technical aspects:

  • Ability to “speak the same language” as business executives, bankers and investors.
  • Adding an extra dimension to engineering analysis: After proposing a technical solution, it can be complemented with an analysis of different purchasing options – upfront payment, financing the project with a loan, leasing equipment, etc.

The benefits offered by an engineering project are strongly determined by the performance characteristics of the proposed system, but the way in which the project is financed also plays an important role.

First Step in Mechanical Engineering Projects: Creating a Cash Flow Projection

A cash flow projection is the basis of financial analysis, and it answers the following questions:

  • What is the upfront cost of the project?
  • What are the net yearly savings?
  • Will a loan be used to cover the upfront cost? If so, what are the terms?
  • What is the service life of the project?

The approach is slightly different for new constructions and major renovations, compared with existing buildings.

  • In the case of new constructions and major renovations there is already a baseline cost to assume, which can’t be avoided. Therefore, any proposed project must be assessed compared to how much it raises or reduces the baseline cost.
  • The baseline cost has already been assumed in existing buildings. Therefore, the full project cost is considered in this scenario.

To illustrate this, assume a heat pump with a cost of $1500 is being considered as an alternative to a $900 resistance heater. In a new project the resistance heater represents a baseline cost, so the real upgrade cost is only the price difference of $600. On the other hand, in an existing building the cost of the resistance heater has already been assumed, and the upgrade must be assessed based on the full price of $1500.

In simple terms: you should consider the cost difference for installations that haven’t been built, and the full upgrade cost for existing installations before beginning your mechanical engineering project. This is the reason why energy efficiency and renewable energy measures offer a higher return per dollar spent in new projects.

For yearly savings and expenses, the approach is the same in both scenarios: they are compared with the expected baseline cost in new projects, and with the current operating cost in existing buildings.

Return on Investment (ROI)

The return on investment, or ROI, can also by defined best though a question: What percentage of the initial investment does the project yield each year?

ROI(%)= (Net Yearly Savings (USD/year))/(Initial Investment (USD)) x 100%

Return on Equity (ROE) – Alternate Analysis when Debt Financing is Involved

Assume the HVAC systems in the example above was purchased with $500,000 from the client’s capital and with a $1,000,000 loan at a yearly interest rate of 4%. In this case, there is an interest payment of $40,000 for the first year, reducing net savings to $210,000. The ROE would be:

ROE(%)=(Net Savings After Interest (USD/year))/(Client’s Equity in Project (USD))=($210,000/year)/$500,000 x100%=42%

Internal Rate of Return (IRR)

The internal rate of return (IRR) can best be described as the interest rate the project would yield if it was a stock portfolio or bank account. Therefore, a project with an IRR of 10% would perform better than an investment yielding 8% interest per year, but would be surpassed by another option yielding 12% per year.

Like the NPV, the IRR is not limited by variable cash flows and loan payments, and can be calculated directly with Microsoft Excel with the following formula:

=IRR (Select all yearly cash flows, including the upfront cost)

Concluding Remarks

Financial analysis can add considerable value to engineering design and consulting services, since the client can rest assured that the proposed solutions make sense from both the technical and financial standpoint. For contractors, it can also be a powerful marketing tool – a client is more likely to carry out a mechanical engineering project if the numbers can prove it is a good business decision.
