3 reasons to apply computational fluid dynamics on your next project

3 reasons to apply computational fluid dynamics on your next project

From right-sizing mechanical systems to understanding the impact of design alternatives, CFD offers a host of benefits for the Building Team.

A misperception about computational fluid dynamics is that it is only effective when designing a jet plane, a formula one car, or an outer space rocket. Today, building designers can apply the same basic principles in fluid dynamics tested on these exotic high-flyers to common building airflows. 

Here are three reasons why you might consider CFD for your next building project. 

1. Best guess approach — Although guided by ASHRAE standards, current HVAC specs are usually “best guesses” based on experience with various equipment and designs. Most engineers oversize HVAC units because they just don’t “know” exactly where thermal differentials including cyclic variations, radiant temperature asymmetries, and drafts will happen in an operating building. Using CFD insight, you can right-size HVAC solutions to eliminate redundant equipment and save costs. 

2. BIM modeling is standard  — The widespread adoption of BIM has led to an unprecedented ability to model new designs. Now, engineers and designers routinely run time and light studies, finite element analyses and energy efficiency studies working with the BIM model. The extension of a building model to CFD analysis is not the leap it may have been ten years ago. Now, airflow designers can run through a number of scenarios for ventilation and heating using different strategies inside the actual building model. 

5 benefits of CFD analysis


1. Assess ventilation effectiveness before construction
2. Eliminate equipment redundancy
3. Weigh equipment costs against performance and environmental requirements
4. Substantiate performance claims
5. Locate supply/return for optimal airflow

3. Seeing is believing — CFD analyses produce easy to understand visuals that show the impact of design alternatives, allowing architects to move walls, alter service conduit pathways and change glazing effects—among other things—to improve energy efficiency and occupant comfort. These visuals are crucial in explaining to owners the impact of design changes, airflow strategies and or equipment purchases. When everyone can easily grasp the results of the sophisticated math behind CFD, you can reach agreement more quickly and with a higher level of confidence. 

 

Typically, designers do not have the time, knowledge or technology to perform a CFD analysis. The alternative is to work with outsourced CFD experts to generate the best airflow strategy for your project. The key here is to find the right fit. Make sure your CFD supplier has a demonstrated range of experience with the kind of building you are designing. 

Your CFD partners should recognize precisely how to properly model an environment to reveal key performance insights—thermal stratification and restricted flows, for example. In addition, your CFD consultant should be collaborative—working with the design team to explore options for improvement. 

No matter what kind of project you are designing—a new manufacturing plant, a new residential building or healthcare institution, or a retrofit of a landmark office complex—a proper CFD analysis will save money in initial capital costs and far more over time in building operating and energy costs. As a designer, you can provide your client with a better, less expensive solution.

Bridging the gap: How early architect involvement can revolutionize a city’s capital improvement plans

Capital Improvement Plans (CIPs) typically span three to five years and outline future city projects and their costs. While they set the stage, the design and construction of these projects often extend beyond the CIP window, leading to a disconnect between the initial budget and evolving project scope. This can result in financial shortfalls, forcing cities to cut back on critical project features.
