EP180 Home Monitoring Madness: Tracking Energy, Air, and More with Bill and ELK (July 2024)
Aug 23, 2024Tap to summarizeIn this episode of the Building HVAC Science Podcast, hosts Bill Spohn and Eric Kaiser engage in a lively "duo cast" discussing the various measurements they take in their homes and the reasons behind them. They start the conversation by reflecting on their recent episode with Gary Klein, which inspired Eric to set up a data logging system to monitor hot water temperatures in his home. This leads to a broader discussion about the different tools and devices they use to track energy consumption and efficiency, such as the Emporia Vue energy monitor, which helped Bill identify a faulty installation in his heat pump system. The hosts delve into their personal experiences with various smart home devices, including air quality monitors from Airthings, radon monitors, and even an innovative weather station called Tempest. They share insights on how these devices have provided valuable data, helping them make informed decisions about their home's energy use and indoor air quality. Bill highlights his use of an ERV system that runs based on CO2 levels. At the same time, Eric discusses his plans to upgrade his home's ventilation and dehumidification systems using the Haven air quality monitor. Toward the end of the episode, Bill and Eric discuss their use of fitness trackers, discussing the metrics they monitor for personal health. Bill also mentions his latest acquisition, a Bluetooth meat probe, which he plans to use to perfect his grilling techniques. The episode wraps up with the hosts emphasizing the importance of integrating monitoring tools into everyday life to enhance comfort, efficiency, and well-being and inviting listeners to reach out for more information on the products discussed.

EP137 Growing businesses need structure, EOS can provide it with Derek Pittak (September 2023)
Oct 13, 2023Tap to summarizeI’m not exactly sure when I got introduced to the concepts of EOS, the Entrepreneurial Operating System. It was likely during my 12 week “crash course” in business with Goldman Sachs 10,000 Small Business program or 10kSB (https://www.goldmansachs.com/citizenship/10000-small-businesses/US/ ) – probably one of the 145 people in my National Cohort #6 mentioned it. I read the book Traction by Geno Wickman in 2017 and slowly started integrating the ideas into the way we run TruTech Tools. In the spring of 2022, I re-read it and presented to our leadership team. We decided to go full bore and started the process of adopting EOS company wide in the summer of 2022. On today’s podcast I chat with our EOS implementer, Derek Pittak. Derek shares the key components of EOS with us including dissecting issues, following processes and traction, the execution piece. EOS has a lot of quick tidbits you can pick up. However, if this interest you, I suggest you get the book Traction and read it cover to cover or reach out to someone like Derek.
