In this episode of the Building HVAC Science Podcast, Eric Kaiser is joined by Marco Radocaj from Balance HVAC, who shares insights into his HVAC journey. Marco starts by discussing his background, from an unexpected entry into the HVAC field through his father-in-law's air conditioning company to learning on the job as a new technician with no prior experience. His humorous story of hosing off a generator during his first day illustrates his initial lack of HVAC knowledge and the steep learning curve he faced. Marco explains the philosophy behind Balance HVAC, emphasizing their commitment to improving how homes are balanced regarding enclosure, occupants, and mechanical systems. He highlights the importance of addressing more than just the cooling function, aiming for a holistic approach to home comfort, where systems are measured and fine-tuned to optimize airflow and insulation. He shares his experiences transitioning from working in his family’s HVAC business to starting Balance HVAC, a new company focusing on thoughtful HVAC installation and attic restoration. Throughout the episode, Marco dives into attic restoration processes and how his team uses tools like thermal imaging and pressure balancing to ensure the homes they work on are more comfortable and efficient. He discusses the importance of communication with customers, sharing how Balance HVAC involves clients in the process by educating them on the science behind the solutions. The episode ends with Marco reflecting on his passion for elevating industry standards and his excitement about contributing to meaningful improvements in HVAC services. Marco’s Business: https://www.balance-hvac.com/ Marco was interviewed by R and R magazine in June 2024: https://www.randrmagonline.com/articles/90866-mold-and-the-need-for-attic-restoration More on Balance’s approach: We prioritize the thoughtful alignment of a home's enclosure and mechanical systems. Balance recognizes that homes built two decades ago were designed to "breathe," allowing for natural airflow to regulate temperature and moisture levels. However, modern construction methods and materials have shifted towards creating tighter homes that are not meant to breathe in the same way. This shift presents challenges, as features like energy-efficient windows, cooler attic environments due to improved roofing materials, and encapsulated attics can inadvertently lead to increased moisture, humidity, and environments conducive to mold growth. These issues can arise when homes are not properly aligned with modern building practices, potentially resulting in discomfort, poor indoor air quality, and health hazards. Marco's deep understanding of how homes are designed to perform allows Balance to address these challenges effectively. By identifying homes that are underperforming or straddling building codes, Balance can implement attic restorations that ensure optimal environmental control. This means creating spaces that are not only comfortable but also dry and healthy for occupants. Through a combination of optimal insulation techniques, strategic ventilation solutions, and moisture management strategies, Balance helps achieve the perfect balance between energy efficiency and indoor environmental quality. Their approach is tailored to each home's unique needs and budget, ensuring lasting improvements that enhance both comfort and peace of mind for homeowners.

Lastly, the conversation touches on the broader implications of their work, discussing how placing humans at the center of design and construction leads to more meaningful and sustainable outcomes. They critique the tendency in the construction industry to prioritize efficiency over human experience, drawing parallels to broader societal issues like the overemphasis on caloric efficiency in American food production. Austin and Lucas stress the importance of materials and building methods that respect both people and the planet, suggesting that a focus on human-first design inherently leads to better and more sustainable buildings. https://www.greenbuildingadvisor.com/article/five-factors-of-good-building   https://www.valihomes.com/     This episode was recorded in November 2023.

In this episode of the podcast hosts Eric Kaiser and Bill Spohn welcomed Amit Gupta from AeroSeal, a company specializing in duct sealing technology. Amit shared the backstory of AeroSeal, which was originally founded based on technology invented by Dr. Mark Modera at Lawrence Berkeley National Laboratory. The technology struggled to gain traction under its initial ownership by Carrier, leading Amit, who was working at Carrier post-MBA, to see the potential for significant energy efficiency improvements in homes through duct sealing. Amit's passion for the technology led to the acquisition and reboot of AeroSeal as an independent company in 2010, focusing on sealing ducts, building envelopes, and potentially underground gas pipelines to improve energy efficiency and reduce waste. AeroSeal's technology addresses the inefficiency and energy loss in buildings by sealing air ducts and envelopes with a patented process that injects micron-sized particles to seal leaks from the inside. This approach is likened to a "fix-a-flat" for buildings, aiming to significantly reduce energy waste and contribute to the net-zero energy building goal. Amit highlighted the vast potential impact of their technology, noting that buildings contribute to a significant portion of CO2 emissions and energy consumption, primarily through heating and cooling. By improving the sealing of ducts and envelopes, AeroSeal aims to address this inefficiency systematically, offering a solution for both new construction and existing buildings. The conversation also touched on the challenges and opportunities in promoting AeroSeal's technology. Amit discussed the common acceptance of inefficient HVAC systems by homeowners and the industry's gradual shift towards recognizing the importance of energy efficiency and indoor air quality. The technology's application ranges from residential homes to iconic commercial buildings, demonstrating its scalability and effectiveness. Amit emphasized the importance of action and awareness in adopting such technologies to make a tangible impact on energy efficiency and environmental sustainability.

Eric and I had a great time learning about Classset, a platform that connects skilled trades workers with potential employers. Here's a 3-paragraph summary: Classset was founded by Cooper Newby and his co-founder Nick Jones, who were inspired by their previous experience recruiting blue-collar workers and their belief in the potential of the skilled trades. They saw a need for a platform that would help people learn about and access skilled trades careers, and Classset was born. Classset offers a variety of resources for both job seekers and employers. Job seekers can find information about different trades, compare salaries and training requirements, and even build profiles showcasing their skills and experience. Employers can post job openings, screen candidates, and connect with qualified workers. Classset also has a focus on mentorship and apprenticeship programs, recognizing the importance of hands-on learning in the skilled trades. Classset is still a relatively new platform, but it is growing rapidly. The company has developed a number of innovative features, such as the "Periodic Table of Skilled Trades" and a free applicant tracking system, to help connect job seekers and employers. With its focus on making skilled trades careers more accessible and attractive, Classset has the potential to make a real difference in the lives of many people. AI prescreening and recruiter screening for candidates weeds out the 40% of candidates who are unresponsive so you only interview people who fit your 'must have criteria'. Companies simply funnel the marketing spend that they would put into other job boards and we manage all the ads and screening for companies. At the end of the day, trades companies and candidates are only getting busier so we want to make it as easy for people to connect and advance their careers.
