Technical explanation on energy saving diagnosis

This diagnosis is provided by Hinode and Hitachi Eco Life Institute (Hinodeya Institute for Ecolife co.). It is a review of the calculation logic of 'Eko diagnosis' that is currently being advanced by the Ministry of the Environment from the basics, and it is designed to be compatible with flexible systems such as multilingual.

Effective measures will vary depending on the energy use situation of home and office. By answering within the range to understand, it is possible to analyze and suggest countermeasures with more families situation. However, you do not need to forcibly answer items you do not know. Through logic that guesses the usage situation, appropriate measures are being proposed without having to forcibly answer.

We propose a motion model, and we are calculating approximate numerical values ​​according to input for the proposed contents, but there is no guarantee of accuracy or operation. If inappropriate suggestions or numbers are output, we would be pleased if you could contact us. We will respond to development separately for systems that have reviewed the diagnostic logic.
