Bronwyn Barry (she/her/they/them/it/thingumie) @passivehousebb.bsky.social · 06/06/2026A simple note of thanks received today… Wow. 020
Bronwyn Barry (she/her/they/them/it/thingumie) @passivehousebb.bsky.social · 05/06/2026So that’s a wrap of probably my fave PH conference ever. Hotel Marcel is a dream. I’ve had a BLAST meeting the rock stars of implementation, not waiting around for code to move, but just blasting forward to get shit done. Go team PHN. #PHN2026. 050
Bronwyn Barry (she/her/they/them/it/thingumie) @passivehousebb.bsky.social · 05/06/2026Tim challenged the theme: ‘Profit by experience,’ asking who profits and what’s the experience? Reminding us to keep focused on human outcomes beyond spreadsheets and that electrification needs Passivhaus to remove its massive emissions footprint from so many heat pumps…. (Mic drop.) #PHN2026 043
Bronwyn Barry (she/her/they/them/it/thingumie) @passivehousebb.bsky.social · 05/06/2026Closing plenary by Timothy Lock from Opal drove home the playful punk anarchy ethos embedded in PHPP. (Yes, who knew?!) Loads of flexibility in how to achieve a caring outcome, full of ‘what if’ possibilites. I’m buying ;) #PHN2026 100
Bronwyn Barry (she/her/they/them/it/thingumie) @passivehousebb.bsky.social · 05/06/2026And in California Frontier Energy study confirmed both SFH’s and multifamily bldg’s meet T-24 2025 code compliance in all climates, with opportunities to update CBECC for more granular calibration. #PHN2026. 000
Bronwyn Barry (she/her/they/them/it/thingumie) @passivehousebb.bsky.social · 05/06/2026Had to moderate the most anticipated session of #PHN2026 today so my reportage is delayed, but here’s the more slide: PH multifamily buildings now undisputed perform well above IECC and ASHRAE 90.1 baseline codes in all climate zones. So add alternate compliance pathways already, dammit!!! 094
Bronwyn Barry (she/her/they/them/it/thingumie) @passivehousebb.bsky.social · 05/06/2026The fabulous Paul Ormond breaking down grid benefits of PH with measured data PROVING massive grid benefits of PH+Allelectric. Duh. #PHN2026. 041
Bronwyn Barry (she/her/they/them/it/thingumie) @passivehousebb.bsky.social · 05/06/2026Alexander G-Murray introduces the new essential acronym: DRIPE (demand response something something energy) in his analysis of grid benefits for building to Passive House in MA. “PH incentives are making energy more affordable for ALL ratepayers!” 000
Bronwyn Barry (she/her/they/them/it/thingumie) @passivehousebb.bsky.social · 05/06/2026And the friction between T-24 not being able to recognize so much of PH’s high performance superpowers is being delt and felt in Altadena. Ugh. #PHN2026. 000
Bronwyn Barry (she/her/they/them/it/thingumie) @passivehousebb.bsky.social · 05/06/2026Fantastic survey data from Altadena on Passivhaus design choices and approaches. #PHN2026 010

Fort Collins launching a pre-approved plan program to deliver affordable PH at scale. Altadena collective advocating for PH rebuilds. 010

Bronwyn Barry (she/her/they/them/it/thingumie) @passivehousebb.bsky.social · 04/06/2026The ROI math on #Passivhaus hotels: adds $6 MILLION dollars in asset value to Hotel Marcel. 1194
Bronwyn Barry (she/her/they/them/it/thingumie) @passivehousebb.bsky.social · 04/06/2026Very simple building decarb toolkit for Hotel Marcel, enhanced by #Passivhaus modeling, shared by Bruce Becker. Sizable solar array with battery storage and micro grid. Passivhaus envelope, low load appliances and all electric kitchen makes this viable. 041

Most mandate complex forms which turn roofs into a cluster of complexity, making PV a PITA to install. Such a sad own goal… 130
Bronwyn Barry (she/her/they/them/it/thingumie) @passivehousebb.bsky.social · 17/05/2026I voted today for @katyporter.bsky.social because: - she has political chops AND experience - California needs to (finally) elect a woman Governor - because governance by billionaires is an oligarchy, not a democracy. Go Katy! 000
Bronwyn Barry (she/her/they/them/it/thingumie) @passivehousebb.bsky.social · 14/05/2026Anyone else seeing Californian cities remove design from their 'Design Guidelines' and replace it with arithmetic exercises?

Bronwyn Barry (she/her/they/them/it/thingumie) @passivehousebb.bsky.social · 02/05/2026Singing my song!!! Junked up forms are NEVER ‘better design’ and ALWAYS add cost, complexity, lower structural outcomes, higher energy use and lower durability. It’s 2026 people. Just say NO to planning departments who still want this shite. 061
