Self-consumption and surplus electricity sales, with energy savings achieved through air conditioning control [Control System].
In addition to the self-consumption support function, we are currently developing and proposing a new system that effectively "stores and uses" energy through the collaboration of storage batteries and air conditioning control! A humidifier control system can also be added.
The control system "E&E Solution" reduces electricity consumption through solar self-consumption and air conditioning control. The energy-saving effects of combined air conditioning can reduce the initial payback period for solar power generation. By maintaining comfort while saving energy, electricity costs decrease, leading to cost savings and a reduction in CO2 emissions. As an application for VPP and aggregator businesses, we have established smart meter technology necessary for self-consumption, VPP, and PPA, and we are collaborating with the digital grid. Additionally, we offer a "humidifier control system" as an added feature to the air conditioning control system. Tasks that previously required constant human intervention, such as water replenishment, can now be managed with automated humidification control, providing peace of mind and satisfaction. In continuous operation results within the company, we can maintain a stable humidity environment (45-55%) while saving tap water through intermittent spraying while measuring humidity. In addition to a comfortable space, the energy-saving effects of air conditioning control can recover initial costs. [Example of expansion for the humidifier control system in large facilities] Total investment: 6.5 million yen Air conditioning electricity reduction effect: 2.2 million yen ⇒ Investment can be recovered in 3 years!
