Yesterday we went to Ulm and visisted a Eco suburb with many passive houses and other other sustainable features.
The interesting point is how integrated and unobtrosive the features are, also how comfortable, clean and high the quality is.
The Entry road states that only low emission cars are allowed, polluting cars are banned! This sets the bar and states the values and ambitions clearly at the gate!! There is also a bus stop at the entry
The Entry corner building is a nice block of units, modern swish design and looks to be of high quality.
These Buildings were built for the 2000 Hannover Expo
This development of 17 row houses are passive houses requiring virtually no aditional heating, and have hot water and space heating provided by a central solar / wood pellet system which is run by the local thermal utillity company.
The Wood Pellet boiler is automated and has 20 tonnes of wood pellet storage nearby, refilled yearly by a truck.
The combined hot water/ space heating water tanks are massive and well insulated and are heated by flat plate solar collectors on the roofs, by the wood pellet boiler and by an emergency electric element.
