Efforts to Reduce Greenhouse Gas Emissions
We have installed a solar power generation system and storage batteries at Tabino Hotel Kashima
June 2024
As part of our efforts to reduce greenhouse gas emissions, we have installed a solar power generation system on the rooftop space of “Tabino Hotel Kashima” (64-36 Hiraizumi Higashi 1-chome, Kamisu City, Ibaraki Prefecture). Additionally, we have introduced storage batteries to aim for peak power demand reduction.
As a result, approximately 15% of the annual electricity consumption of “Tabino Hotel Kashima” can now be covered by renewable energy.

Purpose of Installation
By installing solar power generation, we aim to create renewable energy, reduce carbon emissions, and lower electricity costs. Additionally, with the introduction of storage batteries, we aim to cut peak power demand, reduce basic charges, and ensure the operation of specific loads (such as water pumps) during power outages, thereby creating a disaster-resistant hotel.
Energy-Saving Measures
The installation of these systems is expected to reduce the load on air conditioning. Solar panels installed on the sunlit roof will block direct sunlight from reaching the building, thereby reducing the increase in indoor temperature caused by direct sunlight. As a result, especially during periods when air conditioning is in high demand, such as in summer, the load on air conditioning is expected to decrease. By reducing the load on air conditioning, we can expect not only a reduction in CO2 emissions and energy savings but also a decrease in utility costs.
