Dataset of energy consumption and indoor thermal comfort measurements in 20 multi-family dwellings in Madrid, Spain.

This dataset contains measurements of indoor environmental comfort conditions, including temperature and relative humidity, as well as energy consumption data (electricity and gas) from a total of 20 multi-family dwellings (D) located in the city of Madrid (Spain). Of the monitored dwellings, 10 are located within the Urban Heat Island (UHI) area, while the remaining 10 are situated in the Urban Periphery (UP), as shown in Figure 1. The dataset has been fully anonymized to ensure privacy protection and does not include any geographical information that could allow the identification of individual dwellings. This version includes data collected between May 16, 2019, and November 12, 2020, covering approximately 17 months of continuous monitoring. Measurements were recorded at a temporal resolution of 15 minutes, using monitoring equipment provided by Cliensol Energy, whose technical specifications are described in Table 1. The CSV files are organized by dwelling, following the classification based on urban location: Madrid UHI: D01, D02, D03, D04, D06, D09, D11, D13, D15, D16 Madrid UP: D05, D07, D08, D10, D12, D14, D17, D18, D19, D20 For each dwelling, six separate files are provided, containing: Indoor temperature measurements (2 files), Relative humidity measurements (2 files), Electricity consumption data (1 file), Gas consumption data (1 file). This dataset enables the analysis of indoor thermal comfort conditions, the evaluation of energy consumption patterns in residential buildings, and comparisons between dwellings located in urban and peripheral areas. It also supports studies on the Urban Heat Island (UHI) effect, the development of predictive models (e.g., machine learning), and research on building energy efficiency and sustainability.
