and unoccupied rooms . It is observed that the first represents 12
percent while the latter shows 6 percent of the samples.

b) In Figure 4, the study was conducted on provincial basis for in-depth
analysis. Thus, one territory in the observation, “Bangkok” is divided
6
into 3 areas as - inner, middle and outer Bangkok . Findings show that
for inner and middle Bangkok and Nonthaburi, from 2016-18, the OR
had continually increased while outer Bangkok and Samut Prakan had
declined in 2017. This can be explained individually in the following.
For outer Bangkok, it was resulted by stagnant demand for residential
units that lasted in 2017 but for Samut Prakan, caused by an increase
in supply in late 2016. In short, tumble in 2 areas can be described as
demand and supply factor respectively. In 2018, however, the
occupancy rate of the latters had remarkably recovered.

c) The study is furthered by classifying aging of residential buildings into
2 clusters:
1) Old Meters – for those meters registered prior to 2012

5 Empty rooms imply for meters with zero electricity consumption while unoccupied rooms
imply for those which consume electricity less than 20 kWh per month.
