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