California is on a path to decarbonize our grid and in order to support our energy policy, our buildings must shift from reliance on fossil fool gas, to utilize renewably generated electricity. This presentation was shared in SLO as part of their 'Decarbonize our Buildings' events on August 22nd. It dives into the details of a home in a similar climate zone to California's Central Coast, that I designed in 2014 and built using all-electric equipment and appliances. My presentation includes both predicted and monitored energy, and shows that by going BEYOND CODE MINIMUM, I was able to radically reduce energy use, optimize comfort and deliver a very cost-effective building.

Beyond the All Electric Rainbow (Building Decarbonization is more than electrification)
- 1. Beyond The All Electric Rainbow Bronwyn Barry, RA CPHD SLO Electrification Forum Aug. 2019
- 2. Normal people are doing this!
- 3. Induction cooking is clean! (Directly vented to the outside) ▪ Super easy to wipe down ▪ Super fast response time ▪ Super easy to control temperatures
- 5. Heat pump heating & cooling… Heating load: 4.2 kBTU Cooling load: 2.7 kBTU ▪ 1-ton ducted mini-split ▪ Variable speed fan coil ▪ ECM motor ▪ Chlorine-free non-ozone depleting refrigerant ▪ installed in fully insulated attic ▪ (~$5K)
- 6. Condenser outside… ▪ Fujitsu compressor ▪ Very quiet…!
- 8. Heat recovery ventilator… Zehnder ComfoAir 350 ▪ Filtered, FRESH air ▪ Supplied 24/7 ▪ Quiet as a mouse…! ($2,950)
- 9. Make ‘nozzles’ beautiful! Seiho directional diffusers ▪ Never hear your furnace wheeze again! ▪ Direct your air to where you want it
- 10. And old windows useful… Bring them inside & out of the cold! ▪ Dimmable all LED lighting
- 11. Heat pump water heater Stiebel Eltron Accelera 300 80gallon HPWH ▪ Programmable ▪ Fits in the garage ▪ (Needs room to ‘breathe’)
- 12. Barely visible roof ’bling’… ▪ 7.7 kW Sunpower PV array
- 13. Inverter and converter… ▪ Solar inverter for the PV Array ▪ Siemens EV Charger
- 14. My Title-24 Report… 2015 Code cycle: ▪ 57% Space Heating ▪ 23.9% Space Cooling ▪ 0.0% IAQ Ventilation ▪ 0.0% Water Heating OVERALL: 24.9% better (THAN WHAT?)….. I have no idea either! My Passive House Planning Package (PHPP)Outputs: Absolute outputs, clear metrics and measurable targets!
- 15. PHPP PREDICTED MEASURED AV. HOME IN SAME ZIP 4.3x TOTALS: Av. Home in Same Zip: 15,788 kWh Passive House: 6,125 kWh = 38% of standard DIFFERENTIAL AT WINTER PEAK: Av. Home in Same Zip: 2,516 kWh Passive House: 597 kWh = 23% of standard Proof is in the pudding…
- 16. Generation > House use 510 kWh monthly av. used 797 kWh monthly av. produced
- 17. Add the Electric Vehicle… 797 kWh monthly av. produced 726 kWh monthly av. used
- 18. Translate that into $... +$195 +$75 -$230 This means that PG&E owes my clients $50 to operate their house and drive their car! (In theory) +$270 -$230 = $50
- 19. What’s the secret sauce?
- 20. It’s in this (passive) Box… < NO ICE LEFT UNIHABITABLE ½ ICE LEFT STILL COOL>
- 21. Can I do this too? REGISTER FOR 2019 (or 2020): Emeryville: Oct. 10th – Nov.1st https://naphnetwork.org/designer-training/ YES! www.passivehousecal.org
