Indoor environmental datasets in a retrofitted multiapartment building during winter power outages
Two datasets are provided in the form of excel spreadsheets which contain raw data of indoor and outdoor environmental parameters measured during the winter season in a deep retrofitted housing complex, located in Milan. The first dataset, named ”Experimental Data_Flexibility tests_Flat level”, refers to the measurements conducted in one unoccupied flat of the building complex in which the authors have carried out a series of experimental tests under controlled conditions. The experiments consist of measuring the evolution of the indoor air temperature during the charging and discharging of the storage medium, i.e., the building thermal mass, in order to be able to calculate the number of hours the building can remain in a specified comfort range without active energy input. The second dataset, named “Field data_Unplanned energy interruptions_Building level”, reports the measurements of the indoor air temperature in several apartments of the housing block during two real cases of power outage that lasted several days each. For detailed information about the datasets and the methods of data collection and processing, please refer to the corresponding data paper: "Measured indoor environmental data in a retrofitted multiapartment building to assess energy flexibility and thermal safety during winter power outages". The research by Erba and Barbieri, based on the datasets, evaluates experimentally the effect of a deep renovation in increasing the performance of the building thermal mass in acting as an effective thermal energy storage (TES) during winter, able to deliver flexibility of demand, more and more required by the grid or for self-consumption of locally generated renewable energy, and to guarantee thermal safety under extreme conditions, such as a power outage (Erba S, Barbieri A. Retrofitting Buildings into Thermal Batteries for Demand-Side Flexibility and Thermal Safety during Power Outages in Winter. Energies. 2022; 15(12):4405. https://doi.org/10.3390/en15124405).
