New research published in Science and Technology for the Built Environment (#STBE) introduces a groundbreaking open-source platform for grid-interactive efficient buildings (#GEBs). DOI: https://lnkd.in/exMNGnme #ASHRAE members have free online access here: https://lnkd.in/e9MTX9R4.. While GEBs show promise for building decarbonization and grid support, scalable automation systems for grid-responsive control remain scarce. This research led by Lawrence Berkeley National Laboratory (authored by Lazlo Paul, Flávia Andrade Pereira, Anand Krishnan Prakash, Sang woo Ham, Jingjuan "Dove" Feng, Rich Brown, and Marco Pritoni) introduces the Open Building Operating System (OpenBOS), a novel software platform utilizing ASHRAE Standard 223P for scalable GEB applications. The study presents significant innovations in building control technology: a vendor-independent software stack, a methodology for deploying portable control applications, and a virtual testing environment for pre-deployment evaluation. The platform's effectiveness is demonstrated through two GEB applications, achieving energy cost reductions of 28% and 23%, with demand savings of 45% and 47% during shed events while maintaining occupant comfort. The research uniquely addresses key gaps in existing platforms by incorporating semantic models, supporting #ASHRAE223P, and providing comprehensive testing capabilities. This work provides a crucial foundation for scaling grid-interactive building controls and offers practical solutions for the widespread implementation of energy-flexible building operations.

Watching the markets go crazy when they find out the power of #OpenSource projects keeping up and outperforming closed source projects while costing less. The DeepSeek AI emergence over the weekend is obviously shaking some things up in the world of #ArtificialIntelligence. For most, it may not be something we register outside of the headlines of "US Tech Stocks Plunge on News of Cheaper, Leaner, AI Engines from China", but the focus on open source is what we focus on here. We can build things better, together. Check out OpenHVAC if you are in the building automation, hvac, or building science space. Ideas you have are worth cultivating and building! Why not start today? https://lnkd.in/gK9UzzhG #BetterHVAC #OpenHVAC

Berkeley Lab has launched a "Smarter Small Buildings Campaign" to accelerate adoption of best practice rooftop HVAC operations for small and medium buildings. Optimizing the performance of smaller buildings is a significant challenge--but it is a challenge with a very significant payoff. At ACE IoT, we believe #opensource projects, including #volttron, can provide valuable tools for #smartbuilding solutions providers brave enough to target smaller buildings! Shout out to Srinivas Katipamula for his research related to automated system optimization solutions deployed in buildings without Building Automation Systems. Kudos to Office of Energy Efficiency and Renewable Energy (EERE), U.S. Department of Energy and the lab for convening stakeholders and establishing a structure through which stakeholders can share best practices. ACE IoT Solutions LLC is thrilled to be a partner in this important effort. Visit the Campaign's site to learn more and join the effort! https://lnkd.in/e8FPT_P9 Jessica Granderson Eliot Crowe Nora Hart John House Nathan McKenzie Ashleigh Papakyriakou, P.

We want to inspire new projects for the HVAC industry that create better outcomes for owners/operators, end users, technicians, and building science experts. Have an idea and want to discuss how to make it happen with an energized, wicked smart community? Join our discord! https://lnkd.in/gK9M8nHb #OpenHVAC #BetterHVAC #BuildingScience #HVACService

We love listening to #HVAC and #BuildingScience podcasts in this community. The incomparable Bryan Orr put out a short about Occam's Razor recently and we thought it would be well received by our group. Also appreciated the call out to Jim Bergmann and his sentiment that we must become masters of the obvious to become better at what we do. Doing the simple and obvious things well can make everything smoother and easier. Give this 6 minute podcast a listen and let us know what you get out of it. What can we build to make the industry better? https://lnkd.in/g67V9DaS #OccamsRazor #OpenHVAC #HVACService #BetterHVAC

Our friend Philip Agee just published a new paper on #smartthermostats striving for human-centered problem solving and ease of use. Philip wrote a blog for us a few months back diving into #OpenSource datasets for the #BuildingScience community. Give that a read below, and then head over to read his new paper. https://lnkd.in/dRFwpchu #OpenHVAC #BetterHVAC #HVACScience #BuildingScience

Amazing to get a shoutout on the recent Building HVAC Science Podcast with Bill Spohn, P.E. and Eric Kaiser of TruTech Tools, LTD.!! A great podcast that deserves a follow on the streaming app of choice, Bill and Eric take a deep dive into all things that relate to buildings and people in the built environment. Our members Chris Hamilton and Jason Prince were able to have great conversations with the TruTech team and others at the U.S. Heat Pump Summit in Denver. It's always easy talking about #OpenHVAC and #BetterHVAC principles! https://lnkd.in/gqJJMDTi #buildingscience #hvaclife #hvacmaintenance #hvacservice #heatpump #

The Open Home Foundation is here. It fights for the fundamental principles of privacy, choice, and sustainability for smart homes - and for every person who lives in one. When I started working at Nabu Casa in 2023, Paulus and Pascal told me of their ambitious idea to start a foundation to protect the Home Assistant project. Many months of hard work and serious thinking went into the preparations, coming up with the best way to create the right legal entity to protect the project and give us a vehicle from which to advocate for our users - towards industry and politics. Then, when?the thinking was done, the paperwork was dry, and the legal formalities?were concluded, a whole new phase of the project started. The foundation existed, but now it had to be made tangible... In less than?2?months, our team created the entire Open Home Foundation brand. Wrote the copy that would explain our intent and our principles in the most comprehensible way. Designed how this organization should look and?feel,?and then built the website to match.?Organized?the State of the Open Home event,?last Saturday, where we announced this new foundation to the world.?And?then?launched it all, just like planned. In less than?2?months, we pulled off something that would take a much larger team well over a year at many organizations. And I'm incredibly proud of the result! I want to thank Annaclelia, Missy, Madelena, Paul, Russ, and Gerrit for their hard work. We created something?truly good, and I can't wait to see what the Open Home Foundation will achieve in the future!

Thanks for using an #opensource approach to add value to the residential building industry, Ryan Buckley!

Yesss Jordan Day you’re killing it! Keep it up!
