## 4 Conclusions
\begin{table}
\begin{tabular}{c c c} \hline \hline
**Variable** & **Symbol** & **Description** \\ \hline
**Number of Household** & \(X^{\prime}_{HO}\) & The number of persons permanently occupying a household. \\
**Occupants** & \(X^{\prime}_{BS}\) & The size of a households’ building in square meters. \\ \hline
**Building Size** & \(X^{\prime}_{BA}\) & The building age is taken into consideration as a categorical variable with four general categories: \\
**Building Age** & \(X^{\prime}_{BA}\) & 27 years or younger \\  & & Between 40 and 28 years \\  & & Between 50 and 41 years \\  & & 51 years or older \\ \hline
**Building Type** & \(X^{\prime}_{BT}\) & The building type a household is residing in, partitioned into five categories. The values of this categorical variable range from one to five. \\  & & Apartment (‘Apparent’) \\  & & Row House (‘Tussenwoning’) \\  & & Detached House (‘Pristiaand’) \\  & & Corner House (‘Hoekwoning’) \\  & & Semi-detached House (‘Twee under een kap’) \\ \hline
**Terrain Type** & \(X^{\prime}_{TT}\) & Terrain Type is a categorical variable that indicates whether a household is located in an ‘Urban’, ‘Suburban’, or ‘Rural’ area. The categorization benchmark was set as follows: \\  & & Rural—less than 1000 inhabitants per km2 at household location \\  & & Suburban—between 1000 and 3000 inhabitants per km2 at household location \\  & & Urban—more than 3000 inhabitants per km2 at household location \\ \hline
**PV Panel Ownership** & \(X^{\prime}_{PV}\) & PV panel ownership is included as a dummy variable, indicating 1 as ownership and 0 as non-ownership. \\ \hline
**Ventilation Type** & \(X^{\prime}_{EH}\) & Attributed for by a categorical variable. Houses in our study either have ‘Natural’ or ‘Mechanical’ Ventilation. \\ \hline
**Road Insulation** & \(X^{\prime}_{RI}\) & Availability of roof insulation is included as a dummy variable, indicating 1 as available and 0 as not available. \\ \hline
**Solar Heating** & \(X^{\prime}_{SH}\) & Availability of solar heating is included as a dummy variable, indicating 1 as available and 0 as not available. \\ \hline
**Solar Influux** & \(X^{\prime}_{SI}\) & Potential PV production amount and sunshine intensity measured as the Solar influx in \(\mathrm{J/cm^{2}}\). Solar influx was measured as hourly data from the Ministry of Climatology of the Netherlands (KNMI). Moreover, solar influx information was taken from 20 different weather stations. Each household received the solar influx information from the weather station closest to the household. \\ \hline
**Time-of-Use Price (TOU)** & \(p_{TOU}\) & The TOU electricity prices are composed of a marginal fee of the electricity provider that reflects the forward price and a risk premium. The TOU electricity price changes between peak- and off-peak times. \\ \hline
**Real-Time Price (RTP)** & \(p_{RTP}\) & The real-time electricity prices are the APX electricity market prices plus any additional \\  & & surcharges that are generally applicable to electricity end-users. \\ \hline
**Price Sensitivity** & \(\theta_{i}\) & Price Sensitivity, calculated as: electricity usage/electricity price. \\ \hline
**Relative Electricity Usage** & \(\overline{U}_{i}\) & Relative Daily Electricity Usage. \\ \hline \hline \end{tabular}
