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 June 2016, was released in September this year. The latest report, which covers the results for the period ending September 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) nearly unchanged quarter-on-quarter. The energy cost (solid line) decreased below the level before the earthquake in 2011, reflecting the sharp decrease in the price per unit.
