Auditoria and Public Halls. The preserved Architectonic Heritage, in the Perspective of Sustainability
AbstractTheatres and auditoria have only rarely been "virtuous" examples for energy use both for their peculiar space requirements and for the discontinuity of their use; such statement is even more true when such spaces are located and hosted within monumental buildings such as former churches or industrial areas; that is a quite frequent case in the Italian urban contest. To re-think critically the entire process - from political-planning decision-making to the managing phase – does represent a key step to prevent the decay and abandonment of works of great value and great architectonic and cultural significance. To that aim, three cases of architectonic and historic quality, located in Torino (Italy), are reviewed
Towards the electrification of buildings heating - Real heat pumps electricity mixes based on high resolution operational profiles
The energy transition driven by the need of a deep decarbonization to limit the world temperature rise
requires coordinated actions across the whole energy sector. Among other measures, the strong development
of renewable energy sources in the power sector is gaining momentum in different parts of the
world. The possibility of producing low-carbon electricity leads to a renovated interest in increasing
electricity penetration in final sectors, especially in transport and buildings heating. However, a large
share of renewable electricity comes from non-dispatchable sources, notably wind and solar PV, and
their daily and seasonal variability needs to be matched with the demand profiles of those sectors. In
particular, the charge of electric vehicles shows a relatively constant demand on a seasonal basis while
attention must be paid on the daily operational logic to fully exploit available power from solar and/or
wind. On the other hand, the operation of heat pumps for building heating shows a strong seasonality
that may be an issue in countries that have a larger renewable production during summer. This research
work is focusing on this specific issue, with the aim of improving the common practice of evaluating
energy consumption and emissions on an annual basis, thanks to a detailed analysis based on hourly
time-step, both for the electricity generation mix and for the heat pumps demand. To increase the
significance of the results, different countries across Europe have been analyzed and compared
