On the Season 2 debut of Lost Cultures: Living Legacies , we travel to Bermuda, an Atlantic island whose history spans centuries and continents. Once uninhabited, Bermuda became a vital stop in transatlantic trade, a maritime stronghold, and a cultural crossroads shaped by African, European, Caribbean, and Native American influences. Guests Dr. Kristy Warren and Dr. Edward Harris trace its transformation from an uninhabited island to a strategic outpost shaped by shipwrecks, colonization, the transatlantic slave trade, and the rise and fall of empires. Plus, former Director of Tourism Gary Phillips shares the story of the Gombey tradition, a vibrant performance art rooted in resistance, migration, and cultural fusion. Together, they reveal how Bermuda’s layered past continues to shape its people, culture, and identity today. Learn more about your ad choices. Visit podcastchoices.com/adchoices…

In this episode of the Building HVAC Science Podcast, host Bill Spohn is joined by co-host Eric Kaiser and guest Russ King to discuss various aspects of HVAC design, focusing on the complexities and updates to Manual S, a critical document for HVAC equipment selection. Russ King shares his extensive background in building energy modeling and HVAC design, including his journey from traditional HVAC methods to co-founding Coded Energy, a company that developed Kwik Model 3D, a 3D modeling software for load calculations, which has greatly simplified and improved the accuracy of HVAC designs.

The conversation delves into the intricacies of Manual S, highlighting how it has evolved to better address modern challenges in HVAC design, particularly with the rise of variable speed equipment and the need for more precise dehumidification strategies. The guests discuss the importance of proper equipment sizing to ensure comfort and efficiency, and they explore how Manual S provides a structured approach to this process. They also touch on the challenges contractors face in following these guidelines, noting that despite the benefits, a relatively small percentage of designs adhere strictly to Manual S due to a lack of awareness or understanding within the industry.

The episode concludes with insights into practical HVAC design challenges, such as thermostat placement and the importance of air distribution, emphasizing the need for continuous learning and application of best practices. Both Eric and Russ stress the value of using accurate data and following established guidelines to improve the overall quality and performance of HVAC systems, urging listeners to engage with the math behind the designs and to collaborate with others in the industry to refine their skills.
