Hi Marcus,
I am working on a project in KSA of about 404330ft2.
According to that area and with reference to ASHREA appendix G, a water cooled chiller should be considered in baseline of the model.
The HVAC represents 56% of the total energy consumption of the building.
The building is totally under the ground and complying with ASHREA requirement for envelope, heating, lighting,...etc.
The availability of water and approval of municipality to provide water for the HVAC system is almost impossible and if so contractor shall extend the grey water line for about 60km to reach the site.
The other option is to transport water by vehicles and this can severely affect the operation of the building.
Is there any possible solution? or can be any relax to this prerequisite to respect the environmental conditions of this project?

You are not required to install a water cooled chiller for your project. You are only required to model a water cooled chiller in the Baseline model.
