Abstract
In the context of the EU project “Sinfonia”, that aims to reduce Bolzano’s primary energy consumption up to 40%, SEL AG, an Italian energy company is planning to extend the existing district heating and cooling (DHC) network and explore strategies to improve efficiency, environmental, and economic performance. This research aims to assess the potential energy saving of temperature and peak heating load reduction in the Bolzano’s DHC network. Historical performance data from district heating (DH) users were collected
and residential building were classified based on construction year and energy performance. The thermal properties of the identified representative
buildings were used to develop an indoor climate and energy simulation model by means of IDA-ICE software. The simulation model was validated through
real on-site temperature measurements. The potential reduction of temperature supply and peak heat load was evaluated by creating different temperature night
setback scenarios. Results indicate that the temperature supply level could be decreased on the consumers’ side up to 60 °C, without significantly affecting people comfort. Moreover night setback strategies produced a reasonable reduction of the peak up to 35% from the initial condition, increasing the
energy consumption by 4 %.
