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.
