Electric Power Consumption by Office Tenants
Reduced by 15% in summer and 5% in winter from the pre-quake level
Xymax Real Estate Institute calculated the electric power consumption by office tenants with the data of tenants in office buildings under Xymax Group’s management across Japan, and compared the changes before and after the earthquake in the areas covered by Tokyo Electric Power Company (TEPCO).
As part of corporate social responsibility, many companies today have a strong interest and concern in energy issues ranging from global warming to nuclear power. The shutdown of nuclear power plants after the Great East Japan Earthquake may be a particular concern for businesses in Japan. However, evaluating the current electricity use and taking appropriate measures to solve energy related problems was difficult as there was no available quantitative data of electric power consumption by tenant.
KEY FINDINGS
- ・On an annual average, the electric power consumption by office tenants after the earthquake was 10% lower than the pre-quake level.
- ・In summer (July – September), the electric power consumption was approx. 15% lower in 2011 and 2012 than it was in 2010 (before the earthquake).
- ・Whereas in winter (January – March), the electric power consumption was only approx. 5% lower in 2011 and 2012 than it was in 2010 (before the earthquake).
The electric power consumption by office tenants may be a useful data not only for real estate businesses but also for general occupiers of office buildings when considering energy issues.
Xymax Real Estate Institute will continue to provide data regarding these issues and conduct further analysis on background and factors for the changes as well as further studies on energy consumption per building.
