    Episode 4: 'There’s No Such Thing as a Free Thermodynamic Lunch.'

    Episode 4: 'There’s No Such Thing as a Free Thermodynamic Lunch.'

    The building industry needs to share its failures so future projects can be better, says John Straube, Ph.D., P.Eng., Associate Member ASHRAE. In this episode, John and Joseph Lstiburek, Ph.D., P.Eng., Fellow ASHRAE, discuss why human judgment is critical to a better built environment.
    John and Joe start the episode by talking about how “there’s no such thing as a free thermodynamic lunch” (1:57) and the unintended consequences of striving for increased energy efficiency, sustainability and carbon neutrality (2:12).
    Then, they discuss why it is important for the building industry to openly talk about failures so that professionals may build on the lessons from the past (4:27). John and Joe also talk about the importance of understanding building science to help diagnose problems and prevent future failures, and later, dive into lessons learned from building materials and enclosures as well as challenges from COVID-19 mitigation recommendations, such as ventilation and humidity (17:47).

    Episode 3: Exploring HVAC&R’s New Connected Data Frontier

    Episode 3: Exploring HVAC&R’s New Connected Data Frontier

    In this episode, Sheila Hayter, P.E., Presidential Member/Fellow ASHRAE, and Chuck Gulledge, P.E., HBDP, Presidential Member/Fellow ASHRAE, talk about the future of the HVAC industry and the built environment as they evolve with the help of Industry 4.0 technologies and ASHRAE's Vision 2030.
    They dive into how buildings will be integrated and work as a community (2:58) and how data integration and optimization can help engineers make better decisions to monitor and adapt energy use (10:30). 
    Then, they dig into how digital connections create data-driven practices for operations (7:50), including creating the ability to process and transform data to help engineers make decisions (8:25) and how buildings will be able to better respond to occupants’ needs in the moment (8:45). 
    Sheila and Chuck also talk about Industry 4.0 technologies, such as digital twins (11:00), Lidar (18:03), mixed and virtual realities (18:50), generative design (25:25) and computational fluid dynamics (19:49). 
    The duo also discusses how the new ASHRAE HQ is using Industry 4.0 technologies—including a digital twin (12:47)—while serving as a learning lab for the HVAC&R industry.

    Episode 2: What You Don’t Know Can Kill You

    Episode 2: What You Don’t Know Can Kill You

    In this episode, Greg Nilsson and Mike Gallagher, P.E., Fellow ASHRAE,  discuss their personal histories dealing with smoke events before diving into the new planning framework from ASHRAE Guideline Project Committee 44P, Protecting Building Occupants from Smoke During Wildfire and Prescribed Burn Events (2:05).
    They talk about the importance of the framework as it establishes the significance of planning for these prescribed smoke events or wildfires (8:40) instead of waiting until the event is happening to purchase air filters and other tools.
    Greg and Mike dive into the framework, including air filters, such as MERV 13 (14:30), outside air intake (19:20), lite building pressurization (19:00) and economizers (20:55). They also discuss how to deal with smoke-induced odor (11:50) and the health implications of these smoke events (11:55). Going deeper into the health implications, Greg discusses PM2.5 (12:20).

    Episode 1: 'If You Were Waiting for the Opportune Moment, This Is It.'

    Episode 1: 'If You Were Waiting for the Opportune Moment, This Is It.'

    Epidemic Task Force Chair William Bahnfleth, Ph.D., P.E., Presidential/Fellow ASHRAE, and Jason DeGraw, Ph.D., Member ASHRAE, discuss the task force’s guidance, including its Core Recommendations, and how the COVID-19 pandemic could create long-lasting change in the HVAC&R industry.

    In this episode Bill and Jason discuss the origins of ASHRAE’s Epidemic Task Force’s Core Recommendations (3:18), which were created to help various stakeholders stay on the same page and provide an entry point into the task force’s more than 400 pages of guidance. They skim key points of the Core Recommendations (8:20), including: ventilation (8:22), filtration, air cleaning (9:50), air distribution (11:05) and air mixing (12:30). 
    Then, they dive into the ETF’s HVAC system operation guidance, focusing on maintaining temperature and humidity design set points (16:50), maintain equivalent clean air supply (17:16) and space flushing (18:08).
    Bill and Jason also talk about how the guidance is not a checklist but require engineers to look specifically at their buildings before thinking about how to apply this information (15:18). 
    Looking ahead, Bill and Jason share their thoughts on possible projects that could keep the ETF busy in the future (24:25), such as studying the effectiveness of ventilation and air distribution as well as developing and updating standards that reflect emerging technologies. They also touch on lessons they have learned at this point in the pandemic and their hopes of how the HVAC&R industry will follow through on these advancements and not forget its progress (25:20).
