Modeled on man: Breathable skin for buildings

#1
Biologist turned architect, Doris Kim Sung, is working on another energy efficient and passive method of ventilating buildings, taking inspiration from the human body in search of a more sustainable design. She is advocating the fairly simple yet ingenious idea of a breathable skin, like that of the porous human skin, to encase buildings.

"Isn’t air conditioning in temperate climates an unnecessary waste of energy? ... wouldn’t it be more efficient to just open a window instead? " Good luck with that in Florida. Open a window, it gets hotter.

Good luck with that in most of the country.

exactly. the skin doesn't just "breathe", there's energy being spent in order to heat or cool the body down, as a reaction to the enviromental temperature.

buildings spend energy to cool down/warm up because the outside temperature is unfavorable. Can't see how opening the windows would help

Florida is not in a temperate climate.

The article is talking about temperate climates, whereas Florida is humid subtropical in the north and central parts and tropical in the south.

In temperate climates, the temperature outside might be just cold enough, but not too cold, that "opening the windows", or something equivalent, might be a viable strategy.

add to that most buildings are not designed with good air flow in mind. While my house, built in 2006, has a great HVAC system complete with returns in all rooms no real thought was given to how air flows through the home from the outside.

This is evident by some rooms feeling stuff regardless of open windows and others just downright unfriendly to anything loose. Toss in dark shingles (brown or darker) and a lack of large trees and most modern homes are not really habitable in summer without air conditioning. Fortunately I have ceiling fans in all rooms I spend time in but I wish architects for regular housing would spend more time with making a home livable with natural movement of air.

Not in a well designed house, actually. I lived in Cuba, and in all the older houses it was quite cool during the day, if the windows were open.

I have no idea how they did it. This was mostly in coastal areas, so there was much wind. But it even worked in inland areas. The windows did not let in much light. There was usually no air conditioning, and inside was generally much cooler than outside.

In any modern buildings, air conditioning was required. I also expect this system might not have held up in the warmest summer months.
