Who pays the chiller / cooling charges - me or the landlord?
It depends on the system. In 'chiller-free' buildings the landlord pays cooling, while with district cooling (Empower, Emicool) tenants usually pay the consumption charge and the fixed capacity charge falls on either party depending on your contract addendum. Electricity and water (DEWA) are always the tenant's, and if the contract is silent disputes go to the RDSC.
