2 Introduction

The NZ GREEN Grid household electricity demand study recruited a sample of c 25 households in each of two regions of New Zealand (Stephenson et al. 2017). The first sample was recruited in early 2014 and the second in early 2015. Research data includes:

  • 1 minute electricity power (W) data was collected for each dwelling circuit using GridSpy monitors on each power circuit (and the incoming power). The power values represent mean(W) over the minute preceeding the observation timestamp;
  • Dwelling & appliance surveys;
  • Occupant time-use diaries (focused on energy use).

NB: Version 1 of the data package does not include the time-use diaries.

The purpose of this report is to:

  • create a household attribute file that can be linked to the project power monitoring data;
  • describe the household attribute data.

The resulting cleaned data has no identifying information such as names, addresses, email addresses, telephone numbers and is therefore safe to share across all partners.

The data contains a unique household id (linkID) which can be used to link it to the NZ GREEN Grid time use diaries and dwelling/appliance surveys.

3 Load data

3.1 Household master dataset

Table 3.1 shows the number of households in each area.

## New names:

In total we have 44 households in two sample areas.

3.2 Appliance data

Household appliance ownership was recorded during recruitment using a detailed survey. However this data is not readily available for all households at present. Table 3.2 shows the number of households in each area for whom summary appliance data exists.

Table 3.2: Sample (appliance summary file, NA indicates no data)

The appliances recorded in this summary are shown in Table 3.3. Note that some of this information is also recorded in the household survey data.

3.3 Household survey data

The Energy Cultures 2 survey (Wooliscroft 2015) was used to collect data on household energy and transport attitudes/behaviours and usages. The long form of the survey was used for some households and the short form for others.

Table 3.4 shows the number of households in each region who responded to each survey.

5.6 Notes variable

The notes column may have been set for any number of reasons and means the monitoring data for a given household should be used with caution.

6 Summary

The following table (6.1) shows the key columns of the household attributes file. The data can be linked to the gridSpy data using linkID. linkID is used to flag the two re-used GridSpy units. As an example, unit rf_15 was re-used in a different household. We have therefore created linkID so that the correct household data (rf_15a or rf_15b) can be linked to the GridSpy data (coded rf_15) at the correct date.

Note also that data exists in the GridSpy power demand data for whom no household data exists (e.g. rf_01 & rf_02).
