The paper presents monitoring results from the implementation of energy efficient buildings, renewable energy supply systems and energy management in a sustainable neighborhood in Germany. The whole quarter has low energy standard buildings, which have been monitored for heating and electricity consumption. About 80% of the heating energy demand and 50% of the electricity consumption of the whole area is supplied by a wood fired co-generation plant with 1 MW electrical output and 5.3 MW thermal power output. In summer the heat from the network is used for decentralized absorption cooling in one of the office buildings. The main performance results of this monitored area are presented and the potential for replication are discussed.
