About This Product

■Enepro21Regular development concept
-Energy simulation software that can handle next-generation energy design and evaluation. It is both highly accurate and easy to use, and has the same capabilities and reliability as professional engineers.

-Flexible support for highly efficient system design that matches the load characteristics of buildings, facilities, and regions

-Accurately reproduces the annual operation of existing equipment on a computer, and can use this as a base case to perform accurate energy-saving diagnosis and renewal proposals

-A "general-purpose technical software" that is easy for anyone involved in energy to use

-Enriched built-in Help and published calculation formulas. A software that eliminates black boxes

■Enepro21Regular Ver6 wins the "Environmental Contribution Special Award"
We won the "Excellent Award" and "Environmental Contribution Special Award" in the software category at the 35th "Small and Medium-sized Enterprise Excellent New Technology and New Product Awards." (Sponsored by Resona Small and Medium Enterprise Promotion Foundation, Nikkan Kogyo Shimbun) The system was recognized for its ability to simulate optimal system design and energy operations by integrating power generation equipment (combined heat and power), photovoltaic power generation equipment, battery storage systems, and energy resources that correspond to consumer energy loads to achieve carbon-free society in 2050.

Features of Enepro21 Regular
■Accurately reproduces existing energy equipmentThe annual operating performance of existing equipment can be reproduced with high accuracy, and the annual energy consumption of individual heat source equipment and total energy can be reproduced with an error range of 1 to 2% from the energy consumption of the actual equipment. This is because the balance of power, heat, and flow rate can be accurately reproduced in the operating state.

■OtherThe results of the air conditioning control system (temperature, humidity, outdoor ventilation, etc.) on the secondary side (building side) are all summarized in the power load, heat load, and return temperature difference of cold and hot heat on the energy supply side (heat and power equipment side). Centralized heat and power equipment is simulated based on data on power, chilled water, hot water loads, and the temperature difference between chilled water and hot water return as a result of controlling the secondary (building) air conditioning equipment.
- A system can be easily built by combining system flow devices.
- Pumps, auxiliary cooling towers, and auxiliary heat exchangers attached to the equipment are automatically connected.
- Equipment types and models can be downloaded from the "Enepro21 Database" and easily set up.
