The City of St. Paul has a Sustainable Initiative and the Council Matters video program recently covered what St. Paul is doing to become more efficient.

They interview Dave Nelson, the city of St. Paul's real estate manager, about a new building that will use 45% less energy than one built only to code. The building uses special asphalt that allows water to drain through it to the earth rather than channeling it to a drain.

They have also arranged the building so the offices and conference rooms are in the south of the building to use as much natural light as possible. Other areas have solar tubes bringing light from the roof into the building. Sensors controlling the lights automatically keep light levels even depending on the amount of ambient light.

They are also retrofitting old buildings to use less energy and achieving paybacks of between a 2-5 years from what I remember. The Council Matters program seems like a good source of local news to St. Paul.
