New feature: Include BAU CapEx for ExistingBoiler (heating) and ExistingChiller (cooling)

We are excited to announce a new feature in REopt.jl that gives users more flexibility when modeling existing energy systems! You can now specify optional costs for existing boiler and chiller. This update allows for a more detailed and customizable economic evaluation of your projects, accounting for scenarios where your site’s existing equipment may still incur costs—such as maintenance, upgrades, or partial replacements.

What’s New?

• Optional Cost Parameters:
  You can assign costs to existing boilers and chillers, even if they are not new installations. This is particularly useful for modeling:

  • Anticipated maintenance or refurbishment costs
  • Upgrade or retrofit expenses
  • Partial replacement scenarios

• Enhanced Economic Modeling:
  Incorporating these optional costs provides a more accurate reflection of the true economics of keeping, upgrading, or replacing existing equipment within your REopt analysis, especially when evaluating alternative HVAC technologies like ASHP, GHP, and CHP.

Why This Matters

Many sites have legacy equipment that still impacts their bottom line. By allowing you to specify optional costs, REopt.jl can now help you make more informed decisions about whether to retain, upgrade, or retire these assets as part of your broader energy strategy.

If you have questions or feedback about this new feature, please let us know in the GitHub Discussions or open an issue.
