and the corresponding password on the login screen for the Utilization Data of the Licensed
Software on EIE’s website, subject to consenting to the Terms of Use of the Utilization Dataof the Licensed Software.

1.1

Utilization Data - Equipment Performance Data
Customer can run a rough simulation by using the data regarding the respective modelsof major Japanese equipment manufacturers, as well as the capability and performancedata thereof. Customer can download the data of available Japanese equipment basedon the types and functionalities, and then use such data with the Licensed Software.
- Gas turbine cogeneration- Solar power generation unit
- Low-pressure boiler- Solar genelink- Hot water absorption chiller- Electric turbo chiller- Electric heat pump
- Air-cooled inverter heat pump
- Low-temperature system electric turbo chiller- Heat pump for hot water supply- Gas engine cogeneration- High-pressure boiler- Genelink- Absorption chiller- Water chiller-heater- Inverter turbo chiller- Air-cooled heat pump
- Heat-accumulation integrated model air-cooled heat pump
- Low-temperature system electric heat pump
- Others

Notes: Method for using the equipment performance data: In order to precisely andcorrectly set the performance data of the relevant equipment, Customer should first
download the data of an equipment of a Japanese manufacturer of that is similar to therelevant equipment from among the equipment performance data within the Utilization
Data. Then, Customer should have the Licensed Software read the downloaded dataand run a rough simulation based on such data. Then, Customer should officiallyobtain the equipment performance data of the relevant equipment from the selected
manufacturer, and use such officially obtained equipment performance data to
overwrite the already-read equipment performance data of such similar equipment.
Thereby, Customer can correctly input the performance data of the equipment of theselected manufacturer.

1.2

Customer Support
Customer may view the operation training videos for the Licensed Software to masterthe operation thereof. When Customer uses the Licensed Software for the first time, avideo explains a series of operations from activation of the Licensed Software tooutputting of simulation calculation results. The theme-based videos concretely
explain how to operate the Licensed Software by covering various operation situations.
