Facts and figures about the cold heat network in Mainz (Alte Brauerei)
Uninsulated plastic pipes are used for the heating network. The network does not only supply the buildings with heat to operate the decentralized heat pumps, but also with cooling energy, e.g. for room air conditioning. If heating and cooling demands occur simultaneously, these can be balanced within the 5GDHC network (see also demand balancing in 5GDHC networks). The primary energy factor of the heat supply is 0.5. The district comprises new construction areas only. Buildings are obliged to connect to the heating network. Detailed data of the 5GDHC network in Mainz (Alte Brauerei) is listed in Table 1.
