Recently huge crowds have been stopping by the NY-Engineers.Com website looking for Architectural Engineering in Chicago. That is due primarily due to the following we have built in this kind of work. Nevertheless, many general contractors from Lake Zurich to Prospect Heights, don’t know that NY Engineers is also a top contender for anyone looking for HVAC Firm in Chicago.

The quest for energy efficient buildings involves cost effective 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 will come primarily from 5 different sources including lighting (cooling), your building envelope (cooling and heating), ventilation (cooling and heating), equipment for program use (cooling) and occupancy (cooling).
The ventilation load will be a function of either the mechanisms required to be able to introduce it right into a space and control contaminant concentration or the quantity of persons that can use the area. In virtually all climates inside the southwestern and eastern areas of the usa, to reduce outter air movement will save energy whenever the outer air is either humid and warm or very cold.
Managing the ventilation rate will probably be based on occupancy which is called a kind of demand control ventilation. This can be a everyday sort of energy conservation strategy which is used for spaces with irregular or heavy occupancy. Having cooling and heating loads reduced as low as possible can be carried out through the use of a high performance building envelope, occupancy sensors, and high performance lighting that exploits daylight response of lighting controls.

Chicago HVAC Engineers vs HVAC Techs

If you have ever thought about the distinction between a HVAC Engineers vs HVAC Technicians, then read on:

HVAC engineers will be the folks that oversee setting up of air-con systems for residential and commercial buildings. They spend plenty of their time in offices doing more impressive range management and arranging of installations however they do also see job sites every now and then.

On the other hand, HVAC technicians in Chicago usually do a lot of the hands-on work with repair and maintenance. A HVAC tech may deal with an engineer to complete several of the installation work, specifically for smaller jobs. On the whole HVAC technicians do a lot more travel and may even spend considerable time identifying leaks, changing filters, doing recharges or decommissioning old and outdated systems which use old refrigerants.

HVAC engineers could possibly have the chance to make more decisions about systems that are being used, and they also are definitely the folks that would offer assistance with by far the most sensible refrigerants and which systems would be perfect for a greater building. In the trade, there may be some competition between ‘the suits’ and ‘the ones that get their hands dirty’, but the two jobs do require a great knowledge of how air-con really works. In recent times huge crowds have been browsing our website searching for HVAC Conference 2019 Chicago. With that said, the focus of our company is to be the number one choice for anyone looking for a HVAC Chicago and or any of our other services including Construction Engineering Engineering services.

Heating and Cooling Upgrades: Where to Start? Architectural Engineers Have This Advice

Top Engineering Firms

Space heating represents the highest energy use in many buildings. In addition, domestic hot water and space cooling systems use less energy than space heating, but they are also among the top five building systems that use the most energy. According to architectural engineers, a building can reduce its energy consumption dramatically by replacing its existing heating and cooling systems with modern and high-efficiency equipment.

However, before proceeding with a large-scale building upgrade it is necessary to define a starting point. Building upgrades are investments after all, where the property owner spends capital with the goal of achieving a permanent reduction in building ownership cost. In other words, building system upgrades only make sense from the financial standpoint if the long-term benefit outweighs the associated upfront expenses.

Is There an Upcoming Major Renovation?

Heating and cooling upgrades provide long-term benefits but can be disrupting for building operation. If a major renovation is planned in the short term, it represents an excellent chance to also improve HVAC performance.

A major renovation also provides an excellent chance to improve the building envelope, architectural engineers advise. Poor insulation and air leaks can be detected and fixed, reducing the required heating and cooling capacity after the renovation. This way, the new heating and cooling systems can be specified not only with a higher efficiency, but also with a lower capacity.

  • For example, if you replace a 100-ton air-cooled chiller consuming 1.2 kW/ton with a more efficient water-cooled unit that only uses 0.6 kW/ton, you achieve 50% energy savings.
  • However, if the new unit has a required capacity of only 80 tons thanks to building envelope improvements, energy savings are increased to 60%.

A building envelope improvement can be complemented with a lighting system upgrade. Solid-state LED lighting emits significantly less heat than incandescent, halogen or old fluorescent lighting. All this heat is subtracted from space cooling loads, providing additional energy savings beyond those achieved directly with the lighting upgrade.

Consider that a 60-watt incandescent bulb can generally be replaced with a 10-watt LED bulb, and a 4-lamp T12 fluorescent fixture (4x 34W) can generally be replaced with an integral LED fixture consuming 40-45W. The lighting heat reduction is not significant for a single fixture, but can save several tons of cooling capacity in a building with hundreds of inefficient fixtures.

Building Upgrades: Cost and Benefit

When upgrading a building it can be tempting to prioritize space heating systems, since they consume the most energy. However, it is also important to consider the energy source used by each appliance.

For a given amount of energy delivered, electricity is far more expensive than gas in major cities. Natural gas from Con Edison has a price of around 1.05 USD per therm for residential users, which translates to approximately 3.6 cents per kWh of heat, before considering appliance efficiency. On the other hand, electricity prices typically exceed 20 cents per kWh. Even if most combustion appliances are less efficient than electric appliances, the price of electricity is too high compared with that of gas. This effect is evident in electric resistance heaters, which are around four times more expensive to operate than gas heaters.

Property owners can achieve the best results by getting a professional energy audit before deciding which building upgrades to carry out. With an energy audit, property owners can get a detailed breakdown of energy efficiency measures, along with the expected cost of each. More importantly, an energy audit helps determine the return on investment for each energy efficiency measure – how many dollars will it return over its service life for each dollar spent upfront? Given the price gap between electricity and gas, upgrades that target electric system generally offer a shorter payback period and a higher ROI.

Before proceeding with any building upgrade, checking the Con Edison incentive program is highly advised. Many energy efficiency measures are eligible for attractive cash rebates, which further improves their financial performance. Consider that some rebate programs only apply during certain times of the year or have limited funding, so building upgrades should be planned accordingly.

Importance of Building Type to Architectural Engineers

Not all buildings consume energy the same way. For example, mechanical ventilation typically represents around 13% of energy use in office buildings, but only 1% in multifamily residential settings. This is a consequence of the requirements established by construction codes for each property type – natural ventilation design is mandatory in residential constructions, but designers can choose between natural and mechanical ventilation for office buildings. Domestic hot water systems experience the opposite effect as ventilation systems, representing only 2% of energy use in office buildings but 19% in multi-family residential buildings.

Differences like this are present for many building systems. For example, office occupancy is normally higher than residential occupancy during the day, which extends lighting and space cooling schedules for office buildings, and the corresponding energy expense. However, this does not mean lighting and cooling upgrades should be discarded in the residential sector: these systems represent a reduced percentage of energy consumption but are typically older than those found in office buildings, which can result in an attractive financial return.

Final Recommendations

When deciding which cooling and heating upgrades to prioritize, it is very important to select an adequate time frame for the project, and getting an energy audit to determine the cost and benefit of each measure. Ideally, deep retrofits should be scheduled along with major renovations to minimize disruption and cost. It is also important to find synergy between upgrades, for example when both lighting and space cooling are upgraded. Of course, the financial return is also a very important consideration: as a property owner you will want to prioritize measures that maximize the return on each dollar invested.

In general, energy efficiency measures that target electric systems will have a better financial performance than those targeting gas-fired systems. Nevertheless, there are exceptions to this; an energy audit of the building is the best way to tell, agree experienced architectural engineers.
