“This (pandemic) is an opportunity to make buildings more adaptable. You want to use the right technology so you can keep on harnessing change. Whether it's epidemic mode now, or a better energy savings sequences later on.”

—Deepinder Singh

Pro members get these weekly deep dives, access to the Nexus Vendor Landscape, and can participate in exclusive events with a community of smart buildings nerds.

Episode 13 is a conversation with Deepinder Singh, CEO of 75F.

Summary

  • I walked away from this conversation even more excited about 75F than I already was. As I've said before, 75F and PassiveLogic are the only two companies I know of doing the “blank sheet of paper” approach to modernizing and improving the performance of building control systems.

  • We unpacked 75F's founding story, what makes them unique, and why they decided to create the whole stack rather than just an overlay.

  • We talked about their over-the-air sequence upgrades, how they're similar to Tesla’s, and how they enable the new epidemic mode for minimizing the energy penalty that comes along with the increased ventilation recommended by the CDC and ASHRAE to prevent the spread of COVID-19.

  • Finally, we talked about their software platform, what makes it unique, and their hardware layer, and what makes it unique.

Here’s this week’s Deep deep dive outline:

  • My reaction

  • My highlights

    • Why they decided to build the entire BAS stack and why interoperability isn't always needed at every level of it

    • How 75F's approach to control sequences differentiates them from traditional BAS and works similar to a Tesla

    • Why today's BAS control sequence "best practices" (ASHRAE Guideline 36) are reactive and are really the minimally acceptable option

    • How epidemic mode implements the intent of the CDC guidelines while minimizing energy use.

    • Why their software is Haystack-native and built to be modular and scalable

    • How their network operating center (NOC) and managed services make them look a lot like an analytics company

    • How they're partnering with OEMs of HVAC equipment (that don't do controls) to make 75F plug and play in smaller buildings

    • How their modular approach applies to the hardware level as well and how it saves costs
