Here is a recap of our last monthly meeting on February, Thursday 29th, which took place in Los Altos Community Center.

The Bay St. Passive House was another fight with the HVAC guys. The challenge of heating a highly efficient house is nobody knows how to do it correctly.

California is going to see a lot more forest fires in the future and if you want to be safe in your home, you need to pay attention to air tightness and air filtration.

When you take a poorly built, rotted and rotten house and with a bit of repair work, sheathing, weather resistive membranes, tapes and caulking and a little bit of elbow grease, you can get a house to a level that protects the homeowners from smoke, exhaust, sound and drafts to make an amazing home.

Jake's Passive House is no normal house and this conversation with the home owner David W. is just one of the reasons.


Many of us have heard of air sealing the inside of the house from the outside, and how it is essential for indoor air quality and energy efficiency and how it can protect your family from smog, pollution, car exhaust, smoke, pollen and sound, but what happens when the inside of your house is also producting some pretty bad chemicals? What happens when we need to separate the living portions of a house from the working/hobby portions of a house? That is air-sealing the house and that is what we are having to do for Jake's house, where we have a garage, a metal shop, a brewery, a paint boot, wood working equipment, upholstery fabrication and a server room, and we want all of the heat, smells, toxins, odor, solvents and sounds completely separated from the living space of the house.
Join us as we get nerdy into air sealing.
