Sensor-enhanced housing survey data for urban heat investigation

During the summer months from July 2023 to September 2023 (including a mini heatwave in early September 2023), 40 Smart Citizen sensors have recorded data in homes in Southwark, London, with recording duration from 24 days to 53 days.

This dataset comprises sensor data collected from Smart Citizen Kits (SCK) sensors, along with survey data conducted by the Bureau of Investigative Journalism (TBIJ). The unique ID is utilized as a linking mechanism between the SCK sensor data and the TBIJ survey data.

The SCK (Smart Citizen Kits) sensors captured a range of environmental parameters in homes, including air temperature, relative humidity, air quality, noise condition and light condition. SCK was calibrated in the lab-based environment by the sensor manufacturer first and further corrected based on its operational mode. Further validation procedures were implemented to ensure the accuracy and quality of the air temperature data and relative humidity data by comparing records between survey sensors and commercial sensors (HOBO MX1101 Wireless Temperature and Humidity Data Logger - Optional Remote Monitoring).

Regarding the TBIJ survey data, only housing tenure, housing types, and self-reported housing conditions from the survey data are included in this dataset.

Index of Multiple Deprivation (IMD) quintiles and existing Energy Performance Certificate (EPC) data are also included in this dataset, based on the participants’ home addresses and Unique ID, providing deprivation level of neighbourhoods and energy conditions of homes. IMD data was obtained from UK government and the IMD quintile was calculated based on the IMD decile. The EPC data was collected from Energy Performance of Buildings Search Results

There is a further data collection which contains additional details on survey households’ building conditions, including building insulations and building age, linked and processed from the open EPC dataset. That is available under licence

If you want to link the indoor sensor measurement with the outdoor climate conditions, the nearest local weather station is LIMBO from the UK Met Office

Some initial analysis from this dataset can be found in our GitHub repository
