Join Macauley; Regional Vice-Chair for the Young Engineers in ASHRAE Committee Carrie Anne Monplaisir, Associate Member ASHRAE; and Region X Director and Regional Chair Devin Abellon, P.E., Member ASHRAE, as they discuss how ASHRAE and the engineering industry can be more inclusive.  

The trio define diversity, equity and inclusion (DEI) (1:37), explain what those terms do not mean (3:55) and share their personal experiences related to creating a more inclusive industry (8:55).

Then, Devin and Dunstan—members of the ASHRAE Board of Directors Diversity, Equity and Inclusion Subcommittee—and Carrie Ann dive into how ASHRAE and its committees could be more inclusive (14:00) and discuss how ASHRAE members can help increase the equitable distribution of all resources (8:30), including energy equity (30:45).

Learn more about the ASHRAE Board of Directors Diversity, Equity and Inclusion Subcommittee.

As private companies race to space (22:00 and 25:15), researchers and engineers are working to create built environments in the final frontier (3:12).

To kick off ASHRAE Journal Podcast’s second season, John Constantinide, P.E., Member ASHRAE, and Hamidreza Najafi, Ph.D., Member ASHRAE, discuss how HVAC&R technologies used on Earth can be applied to extraterrestrial indoor environments (3:35) as well as opportunities ASHRAE has to help shape the built environment in space (3:50, 21:30 and 27:25).

The pair also talk about how the International Space Station is an example of a living environment in outer space (4:30) and how the station showcases the importance of HVAC&R technologies and indoor air quality (5:45). Then, they discuss the importance of designing HVAC&R systems that help people exist and survive in the harsh environments of space (5:20), among other topics such as design considerations, non-HVAC elements that affect the built environment and sustainability in space. 

Almost two years ago, Constantinide and Najafi co-authored an ASHRAE Journal article about (2:56) environmental controls in space.

On the latest episode of ASHRAE Journal Podcast, Booth and Dan Dettmers, Member ASHRAE, discuss what controlled environment agriculture demands of HVAC systems (7:55), the patchwork regulations born from increasing legalization of cannabis (26:30) and how cannabis grow facilities are helping the CEA and HVAC&R industries develop equipment as the “grow local” food movement gets louder (40:55). 

Dettmers and Booth start the podcast talking about the three loads CEA facilities demand: lighting, cooling and latent loads (7:55). Then, the duo discusses the high energy use intensity of indoor grow facilities (4:30) and dive into a history lesson of legality and regulations that come along with growing cannabis (4:50 and 22:45).

The trio discuss some of the challenges they came across, such as the task of creating a market-rate net zero energy project (2:13), building envelope issues (3:00 and 20:00) and adhering to a fast-paced construction schedule (3:19). 

Then, Ginger, Greg and Stanton talk about how the design team chose between two options for the building’s HVAC systems (6:13) and how ASHRAE took a more innovative approach by choosing a technology not widely used in the Atlanta area (10:37).

On this episode of ASHRAE Journal Podcast, the co-chairs of ASHRAE’s Task Force for Building Decarbonization, Donald Colliver, Ph.D., P.E., Presidential/Fellow/Life Member ASHRAE, and Thomas Phoenix, P.E., BEMP, Presidential/Fellow/Life Member ASHRAE, define decarbonization (2:45), discuss what the building industry is doing to reduce energy use and emissions (3:50) and share who will be affected by building decarbonization (6:10).

Later, Colliver and Phoenix talk about the plausibility of current carbon goals (10:40) and dispel common myths and misconceptions about decarbonization (16:39).

Then, they wrap up the episode by discussing the task force and its ongoing work (19:54).

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).

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. 

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).

• Dive deeper into the topic with an ASHRAE Journal IEQ Applications column from March 2021 on “Protecting Building Occupants From Smoke During Wildfire and Prescribed Burn Events.”

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).
