As of late A lot of individuals have been taking a look at the NY Engineers website in search of Construction Engineering in the Chicago area. That is due because of the following we have built in this kind of work. However, many building owners from Deerfield to Oak Lawn, Illinois, don’t know that NY Engineers is also a top contender for anyone looking for HVAC Chicago, IL.

The search for power efficient 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 that HVAC systems should come primarily from five different sources 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 function of either the machines required so as to introduce it into a space and control contaminant concentration or the quantity of persons that can occupy the room. In nearly all climates within the eastern and southwestern regions of america, to lessen outter air-flow helps save energy whenever the exterior air is either warm and humid or very cold.
Manipulating the ventilation rate will likely be dependant on occupancy which is known as a type of demand control ventilation. This can be a common type of energy conservation tatic that is used for buildings with intermittent or dense occupancy. Having heating and cooling loads reduced as low as possible can be carried out through the use of a higher performance building envelope, occupancy sensors, and high performance lighting that utilize daylight response of lighting controls.

Chicago HVAC Engineers vs HVAC Technicians

When you have ever wondered about the distinction between a HVAC Technician versus HVAC Engineers, then read on:

Chicago HVAC engineers are the folks that run installing of air cooling systems both for residential and commercial buildings. They spend a great deal of their day in offices doing advanced level management and planning of installations nevertheless they do also visit job sites from time to time.

In comparison, HVAC technicians in Chicago tend to do a lot of hands-on work with maintenance and repair. A HVAC tech may assist an engineer to complete some of the installation work, specifically on smaller jobs. In general HVAC technicians do considerably more travel and could spend time and effort identifying leaks, changing filters, doing recharges or getting rid of old and outdated systems that utilize old refrigerants.

HVAC engineers could possibly have the chance to make more decisions about systems that are employed, and they are the people that would offer assistance with probably the most sensible refrigerants and which systems would best suit a much bigger building. In the industry, there is some conflict between ‘the suits’ and ‘the ones that get their hands dirty’, but the two jobs do require a good knowledge of how air cooling is proven to work. Lately huge crowds have been getting to our website searching for HVAC Supply Chicago Il. Nevertheless, the goal of our firm is to become the number one choice for anyone looking for a HVAC Chicago and or any of our other services including Mechanical Engineering Engineering services. We ask that anybody searching for more information about our Heating and Air Conditioning (HVAC) Engineering Firm in Chicago Illinois checks out at our blog.

Financial Analysis: Your Next Mechanical Engineering Project

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.
