Appendix

In REHO, most of the model parameters can be given through additional files. However, there are default values already implemented in the model. This appendix attempts to report them.

Units

To define the units’ costs, the price per unit installed and the unit lifetime are considered. They are reported in Tables Building units default specifications and District units default specifications.
