CO ² neutral (How to assess?) District is able to self-supply its energy demand (Renewable Energy) Only considering the use phase (e.g. building operation) or the whole life cycle of the district for the CO ² balance (material production, embodied carbon)?

Traditional approach to the building energy retrofitting brings poor results in relation to the urban sustainability, resource efficiency and economic return Use of Synergies and Interactions between buildings is the key for climate neutral urban districts (Renewable Heat Networks, Smart Grids) Isolated retrofitting measures on single buildings may even have negative impacts on the whole district Citizen participation in urban retrofitting projects has to be enhanced

The goal is to store the electricity surplus and to exploit it at the times of high electricity demand in the district Electricity storages are still very expensive The feed-in of the surplus electricty in the electricty grid may lead to a collaps of the electricity system and cause a black-out (overload) The Energy Supply Company will shut down all photovoltaic systems in the district in the noon time in order to avoid the black-out Source: http://whatgreenhome.com; http://channel.nationalgeographic.com
