Overdesigned mechanical or electrical systems is a problem that frequently occurs in the design process. While it's easy to assume that extra capacity is a good thing, the reality is that oversized systems are just as much of a problem as undersized systems . This common mistake results in higher upfront costs for the building owner and can lead to performance issues down the road.
However, avoiding over-engineering in your designs can be difficult. This is because it is difficult to recognize signs of oversized systems in the design process. To design building systems that are energy efficient, low cost and high performing, it is vital to recognize signs of components that are under or over capacity.
To help you better understand this issue, read on for information about the pitfalls of over-engineering and how to prevent this issue from occurring on your next project.
Stop paying more for over-engineered systems.
Discover the five main components you need to watch out for.
What is over engineering?
Simply put, Over-engineering is when a system is designed to be more complicated than necessary for its purpose.
Excessive complexity almost always adds no benefit to the system's functionality, decreases the productivity of the design team, and significantly increases construction proposals.
How does this affect my building?
Many people assume that more robust systems perform better, but this is not the case. Over-engineering leads to a higher price, higher operating costs, and lower performance.
This is because over-engineered systems increase initial labor, material, and installation costs, and are more expensive to maintain overtime due to poor energy efficiency.
Not only are these systems more expensive, they also cause performance issues. Over-engineered components are often less efficient, require more repairs, and have a shorter life cycle than systems accurately sized for the building.
What can I do?
Although it can be difficult to detect the signals, there are systems that are more commonly over-engineered than others.
For example, air conditioners are often oversized in an effort to reduce the temperature in less time. While this may seem like a good idea in the design process, the reality is that this extra capacity wears out electrical and mechanical components over time, resulting in reduced lifespan and poorer humidity control.
There are many other examples like this that are important to know before engineers start designing . Keeping an eye on these components during the design process increases your chances of catching these errors before they make it to installation.
