Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Design and construction of a new building using good environmental thinking is one thing. Here's a building near me that demonstrates a lot of possibilities in new construction.

Retrofitting an existing building is a lot harder. And there are a lot of existing buildings. Somebody asked me the other day about how to retrofit an existing large house with hot water heat. Unfortunately, without existing ducts, it is not very easy. And they had just a few years ago put on a huge addition that could have been done more thoughtfully.
