The dataset comprises gas and electricity consumption, indoor air temperature, and indoor relative humidity measured in 15 different dwellings, local weather data, a dwelling survey, and an occupant survey recorded during Phase 2 of the TEST Project. Refer to the README for data file structure. Heat transfer coefficients (HTC) measured by co-heating test, and fan pressurisation results have been omitted from this dataset to allow for blind prediction of HTC.This dataset was created for the Technical Evaluation of SMETER Technologies (TEST) Project (Phase 2). It was funded by the Department for Business Energy and Industrial Strategy via the Smart Meter Enabled Thermal Efficiency Ratings (SMETER) Innovation Competition: Phase 2.

All data were collected as part of the Technical Evaluation of SMETER Technologies (TEST) Project (Phase 2). It was funded by the Department for Business Energy and Industrial Strategy via the Smart Meter Enabled Thermal Efficiency Ratings (SMETER) Innovation Competition: Phase 2. This dataset comprises a subsample of 15 dwellings, selected for release from the entire sample of 30 dwellings. Each dwelling had a prior co-heating test and fan pressurisation test. These data have been withheld to allow for blind prediction of heat transfer coefficient. The following data have been made available to aid calculation of heat transfer coefficient: - Gas and electricity consumption. - Indoor temperature and relative humidity. - Local weather conditions. - Additional information on the dwelling and the occupants such as boiler type, wall construction, and number of occupants. Gas and electricity consumption were measured via secondary meters at 30 minute intervals in all 15 dwellings. There is an accompanying quality assurance (QA) file for each week of energy data, highlighting any issues. Indoor temperature data were measured at 30-minute intervals in every room in each home using a narrowband IoT sensor (uncertainty: temperature +/- 0.2 deg C; relative humidity +/- 2%). Local weather data were measured at a central site within approximately 6 km of all homes in the sample. Data include dry bulb temperature, relative humidity, wind speed, wind direction, precipitation, barometric pressure, and total vertical solar irradiance (facing south). Information from the dwelling was collected via visual inspection. One occupant in each dwelling was asked: "how many people permanently live here".
