The new Chancellor's Office building is, like the parliamentary buildings, supplied with energy produced according to the highest environmental standards. Heat and power come from a decentralised heating and power co-generation plant which uses rape seed oil as fuel. Surplus heat from the Chancellor's Office is fed into the heat storage system of the Bundestag and can be fed back into the building. The glazed atria also function as collectors of heating energy. A proportion of the electricity used in the building will come from the solar energy panels on the roof of the office tracts.
	Photovoltaics  on the roofs  of the office  buildings			Water resources will also be husbanded in the new Chancellor's Office building: rainwater will be collected in the ceremonial courtyard and the chancellery garden and used for irrigation of the gardens.
