In this episode of Better Buildings for Humans, host Joe Menchefski welcomes back Alejandra Menchaca of AIRLIT Studio for an insightful deep dive into TEDI—Thermal Energy Demand Intensity. As a repeat guest, Alejandra shares her expertise in sustainable and human-centric design, making complex concepts accessible. Together, they unpack the significance of TEDI, distinguishing it from metrics like Energy Use Intensity (EUI) and exploring how it informs passive building design. Alejandra explains why TEDI is a crucial metric in Massachusetts’ stretch energy code, its role in Passive House certification, and its implications for building resilience and grid capacity as electrification accelerates. Listeners will also learn about the challenges of balancing energy efficiency with human-centric design, as Alejandra dispels misconceptions and highlights the metric's potential to harmonize sustainability with occupant well-being. Don’t miss this comprehensive guide to designing better, smarter buildings. Where to Find Ale Menchaca: https://www.linkedin.com/in/alejandramenchaca https://www.design.upenn.edu/people/alejandra-menchaca About Ale Menchaca: Alejandra is a Principal at Airlit Studio, an environmental design consulting practice with a design-minded approach rooted in technical excellence. Alejandra combines expertise in mechanical engineering and building science to give clients a clear understanding of the impact design strategies and innovative solutions have on long-term building performance. Alejandra leverages research and simulations to provide project teams with sustainable design knowledge and energy expertise. With a Ph.D. in natural ventilation, she is experienced in designing passive buildings. In addition to her interest in passive solutions, Alejandra also has extensive experience with energy-intensive buildings such as laboratories and healthcare facilities having worked as an in-house building scientist at Payette for four years. Her experience also includes a focus on the power of early design analytics, gained during her tenure as a consultant at Thornton Tomasetti, where she built their Boston-based sustainability group. Lastly, Alejandra’s expertise also includes thermal comfort, energy modeling, daylighting, and computational fluid dynamics. Ale is passionate about early design building science: assisting design teams with analytics and reports that impact design outcomes. She is a co-founder of Project StaSIO, a community of building performance simulators (consultants, architects, in-house building scientists) that strives to teach others how to ask the right building analytics questions and convey the results in ways that are beautiful and impactful. Highly committed to growing the next generation of sustainability-focused designers and engineers, Ale loves teaching. She has lectured at MIT and the Harvard GSD, where she’s had the good fortune to mentor several brilliant students who have become inspiring disruptors in the building simulation industry.
