Xymax Real Estate Institute has been studying the energy consumption and energy cost of office buildings in the Greater Tokyo area on a continuous basis. The report, which covers the results for the period between January 2010 and December 2015, was released in March this year. The latest report, which covers the results for the period ending March 2016, is available now.
Figure 1 shows the 12-month moving average of the energy consumption, price per unit and cost. The energy price per unit (dotted line) kept falling since March 2015. The energy consumption (dashed line) had a slight decrease quarter-on-quarter. The energy cost (solid line) also continued to decrease reflecting the decrease of the price per unit and consumption volume.
