This is a house that uses absolutely no active heating systems to heat the house, but provides an even and comfortable temperature all year round even when the weather outside is cold.
I’m not familiar with the idea, until I read a couple of articles on the topic:
No furnaces but heat aplenty in the New York Times and Is this the greenest city in the world? in the Guardian.
Of course, the big question: how would you keep a house cool in Taiwan in the hot summers?
