Almost 85% of SFO's Scope 1 & 2 emissions derive from its natural gas-powered CUP. To reduce this, the airport is considering four alternative CUP options: one being gas-powered and three all-electric heat recovery chiller plant designs with various levels of water use. SFO wants to choose an option that: eliminates natural gas; dramatically reduces water usage; reduces the electrical load impact; and minimizes life cycle costs. This session showcases how SFO monetized the lifetime triple bottom line impacts of each option. It will then highlight how they are able to use these results to justify an all-electric option with a higher upfront cost due to its lifetime savings. Lastly, it will illustrate the contribution of this design toward SFO's carbon reduction and sustainability goals.
