As of late huge crowds have been stopping by the New York Engineers website in search of Architectural Engineering in or near Chicago. This is due primarily due to the reputation we have develop in this kind of work. However, many building owners from Lake Barrington to Normal, Illinois, do not know that New York Engineers is also a top contender for anyone in search of HVAC Chicago, Illinois

The pursuit of power efficient buildings involves energy efficient HVAC system design. This may include systems for HVAC, lighting, architectural enclosure, domestic water heating, and vertical transportation. The loads for the HVAC systems should come primarily from five different sources including lighting (cooling), the property envelope (cooling and heating), ventilation (cooling and heating), equipment for program use (cooling) and occupancy (cooling).
The ventilation load will be a purpose of either the machines required so as to introduce it right into a space and control contaminant concentration or the quantity of individuals that will be in the space. In the vast majority of climates within the southwestern and eastern parts of the US, to lessen outside air-flow will save energy whenever the outer air is either warm and humid or very cold.
Governing the ventilation rate will probably be dependant upon occupancy which is referred to as a kind of demand control ventilation. This is a common type of energy conservation policy which is used for buildings with occasional or crowded occupancy. Having cooling and heating loads dropped as low as possible can be achieved by making use of a high performance building envelope, occupancy sensors, and performance lighting that uses daylight response of lighting controls.

Chicago HVAC Engineers vs HVAC Technicians

If you’ve ever considered the distinction between a HVAC Technician vs HVAC Technicians, then please read on:

Chicago HVAC engineers would be the people who supervise setting up of air-con systems for both commercial and residential buildings. They spend lots of their day in offices doing higher level organization and planning of installations but they do also stop by job sites every once in awhile.

In comparison, HVAC technicians have a tendency to do a lot of hands-on work  that deals with repair and maintenance. A HVAC technician may deal with an engineer to perform a number of the installation work, specifically on smaller jobs. Generally speaking HVAC technicians do far more travel and may spend time and effort changing filters, identifying leaks, doing recharges or getting rid of old and outdated systems which use old refrigerants.

HVAC engineers could possibly have the ability to make more decisions about systems that are being used, and they are the people who would offer assistance with the most sensible refrigerants and which systems would best suit a bigger building. In the industry, there is some rivalry between ‘the suits’ and ‘the ones which get their hands dirty’, but the two jobs do require an excellent knowledge of how air-con really works. Nowadays huge crowds have been reading our sites searching for things like HVAC Chicago Repair. With that said, the goal of our organization is to become the number one choice for anyone looking for a HVAC Firm near Chicago and or any of our other services including Sprinkler Design Engineering services. We ask that those looking for more info about our Heating & Air Conditioning (HVAC) Engineering Firm in Chicago Illinois stops by at our Utility Filings blog!

Consulting with an MEP Engineering Professional: The First Step Towards Energy Efficiency

Value Engineering Process Steps

Energy efficiency is always beneficial for buildings since it translates into a direct reduction of operating expenses. This is especially true for electricity bills in large cities. However, consider that energy efficiency is an investment: capital is used upfront to achieve a greater long-term benefit. Just like investors seek advice to find the best way to allocate their capital, property owners should determine the best approach to implement energy efficiency before proceeding with the actual project. The services of a qualified energy consultant or MEP engineering company can be of great help.

Equipment manufacturers often offer energy efficiency advice along with their product offerings, and while it is technically accurate, it tends to focus on their products in isolation from other building systems. For example, an air conditioning supplier is unlikely to suggest building envelope, space heating and lighting improvements to improve overall performance. On the other hand, a consulting firm will take a whole-building approach without focusing on a specific system only, allowing them to suggest the best solution.

Consulting Offers Technical Accuracy

Equipment vendors often follow a “recipe” approach when dealing with energy efficiency, offering you a product and indicating percentage savings achieved with to conventional systems. As a result, the offered savings are based on what is commonly found in buildings and may not always match your site conditions. In other words, the approach followed by suppliers starts at the solution and how it fits a specific building.

Also consider that equipment providers have sales targets to reach, so they are unlikely to suggest measures that will reduce the monetary value of their offering. For example, if your current cooling load is 200 tons of refrigeration, a chiller vendor will probably suggest a 200-ton unit with high efficiency right away, instead of helping you reduce the required capacity.

Energy consultants follow a different approach. Following with the example of the 200-ton chiller, they will first assess factors that affect your cooling load, such as:

  • Lighting: LED products emit much less heat than their incandescent, halogen, fluorescent and HID counterparts. Replacing one lamp does not make a great difference, but the effect is significant for a large building with thousands of them. Replace 1,000 fluorescent fixtures consuming 120W each with 50W LED fixtures, and you have effectively reduced lighting heat by 70 kW (19.9 tons of cooling).
  • Building Envelope: Poor insulation and air leaks increase unwanted heat transfer into and out of the building, driving up both heating and cooling loads. Energy consultants evaluate these aspects before suggesting an equipment upgrade.
  • Automatic Controls: One aspect of energy efficiency is upgrading to equipment that meets building needs while consuming less energy, but using it optimally is equally important. Automatic controls ensure that no equipment operates for more time than necessary, and can also optimize output if the equipment allows it (dimmable lighting, variable-speed chillers, air handlers with variable-frequency drives, etc.)

In this case, perhaps you will only need a 160-ton chiller after improving lighting systems and the building envelope. Assume the existing 200-ton chiller has an efficiency of 0.8 kW/ton, with a power consumption of 160 kW, while the upgrade operates at 0.55 kW/ton. The respective power drawn by new 200-ton and 160-ton units would be:

  • New 200-ton chiller power = 200 ton x 0.55 kW/ton = 110 kW (31% savings)
  • New 160-ton chiller power = 160 ton x 0.55 kW/ton = 88 kW (45% savings)

Assuming 2,400 hours of use per year and an electricity price of 16 cents/kWh, the first chiller consumes 52,800 kWh more per year, equivalent to $8,448 in power bills.

MEP Engineering Consulting Allows an Accurate Financial Analysis

After professional MEP engineering consultants carry out a detailed energy audit for a building, it is possible to know the upgrade cost and resulting savings with a high degree of accuracy, and this information can then be used for a financial analysis. Key decision-makers often have a professional background in business, and would likely prefer to see metrics such as net present value and return on investment, while kilowatt-hour and percentage savings are of more interest for technical personnel.

The annual savings projected after an energy audit are also useful when property owners seek loans for their building upgrades. With detailed information on how upgrades will perform, they can determine if the project can fully cover debt service with energy savings. The consulting service itself can also be considered an investment: Professional savings are paid upfront, before proceeding with a project, to ensure that the best possible performance is achieved.

Legal Requirements and Code Compliance

If you are considering a renewable energy system, consider energy efficiency first. When a building optimizes energy use, a given renewable generation capacity can meet a larger portion of energy needs. For facilities where the plan is to use 100% on-site generation, the required capacity is reduced if energy efficiency is addressed first. From the initial consultation to the finished result, you should have an MEP engineering professional to guide you through this process.
