Termites could hold the key to self-sufficient buildings

I could give them a big hint - rather than studying termites, they could ask some master builders from the last century. They did pretty much the same thing these bugs allegedly accomplish.

Our house was built in 1912 - and it's far more energy efficient than "modern" homes of the same size.

It's sited correctly - on a small rise, to take advantage of both the natural drainage, and the higher wind speeds. Those breezes act to cool the house in summer. The north and west are heavily shaded/recessed, while the south face is open. Today we call that "passive solar", back then they called it common sense.

Mounds built by highly-evolved African termites could inspire new types of building that are self-sufficient, environmentally friendly and cheap to run. The mounds provide a self-regulating living environment that responds to changing internal and external conditions. A multidisciplinary team of engineers and entomologists is looking at whether similar principles could be used to design buildings that need few or no mechanical services (e.g. heating and ventilation) and so use less energy and other resources than conventional structures.

Notes: If you put a <mailto:> link in the URL field your address will not be mangled: this could be a bad idea as your email address could be easily harvested by bots designed for SPAM. The comments field should now format correctly for line feeds and carriage returns: when you hit the 'Enter' or 'Return' keys in your comment it should break to a new line. The text should wrap cleanly. Please let me know if it doesn't. No HTML tags will pass through - entering links seems to be the main cause of comment SPAM. Also, please be sure that Javascript is enabled in your browser before attempting to post a writeback. Sorry for any inconvenience, but this really helps cut down on the amount of comment SPAM I have to deal with.
