Modeling

\label{modeling}
Based on the features initially selected, the linear and nonlinear models were built to predict weather normalized EUI for multifamily and office buildings for 4 years using the same features. The model for office buildings in year 2015 is presented below as an example of these results.

Linear Model

\label{linear-model}
After the linear model is applied, the in-sample r-squared for office buildings in 2015 is 0.275, with an out- of- sample r-squared of 0.213 with 33% data as test data. This model includes 11 features which can be seen in Table 8.
