Computational fluid dynamics (CFD) is a critical simulation tool for sustainability. By integrating CFD into the broader energy-simulation workflow, we can make more informed decisions and illustrate these issues for our clients. The key is to understand how CFD results translate into real-world metrics in terms of thermal comfort and energy. And, ultimately how the value of each strategy compares to other high-performance investment opportunities. This case-study class focuses on one simple example: using CFD to compare finned-tube perimeter heat to radiant ceiling panels in a typical private office. Our class outlines not only the specific steps of the CFD modeling process, but also how this process fits into the overall energy-performance optimization trajectory for the project.

As Director of Sustainable Design at BR+A, Jacob Knowles heads the building simulation and sustainability consulting team. His work focuses on the integration of strategies that reduce environmental-footprint, while supporting occupant wellbeing and maximizing return on investment. Over the past decade, he has championed the sustainability agenda for major research, healthcare and other commercial and institutional projects. Project highlights include achieving LEED Platinum, meeting the 2030 Challenge, and receiving a MA DOER High Performance Buildings Grant. Jacob has presented these success stories and other topics at speaking engagements such as Labs21, NESEA BuildingEnergy, Healthcare Design, Build Boston (ABX), and Tradeline.
Michael Gilroy is an HVAC engineer at BR+A with three years of experience in the design of Heating, Ventilating, and Air Conditioning (HVAC) systems, energy modeling and analysis, systems life cycle cost analysis, feasibility studies, and Building Information Modeling (BIM). Michael's project experience has included healthcare, research, and academic projects for clients nationwide. Michael used his collegiate background in the study of HVAC engineering and CFD to assist in the development of BR+A's in-house CFD modeling services. Michael plans to continue to optimize synergies between HVAC engineering, BIM, and CFD modeling.
Revit MEP software can be a very powerful modeling tool that enables you to explore the building design for a mechanical system. Once the energy calculations are done (either natively in Revit or externally), an optimum design for the building air systems needs to be developed. Traditionally, this has been done using a rule-of-thumb approach or by using simple modeling techniques in Revit. With the seamless translation of models between Revit MEP and Autodesk Simulation CFD software, you can quickly explore design alternatives for diffuser layouts in your models. You can compare design scenarios in Autodesk Simulation CFD using various performance metrics and thus determine the most efficient and best possible layout for your building design.
