66 2021 ESG REPORT Energy Management Energy management is a core element of sustainability at Maxar. In 2021, we identified strategies in our facilities, data centers and information storage for measuring and reducing our energy usage. Also in 2021, we began tracking our energy usage and collected historical data dating back to 2019 to develop a baseline. Our total Scope 1 and 2 energy usage decreased year over year from 2019 to 2021. Our electricity usage and our natural gas usage of 65.8 million kWhs and 1.1 million Therms in 2021 resulted in a 25% and 22% decrease from 2019 baseline values, respectively. The primary drivers for our energy reductions were related to facility consolidations and moving our data and computing to the cloud. The following details actions we take to manage energy within our operations. Facilities Our main facilities employ building monitoring systems to optimize HVAC settings and air balancing to reduce energy usage. Additionally, our real estate team continually assesses office needs: four facility consolidations were completed in 2021 resulting in energy consumption reductions. We have ongoing programs to upgrade less-efficient heating and cooling equipment, power systems and lighting infrastructure. For example, our headquarters facility recently upgraded to a light-harvesting system, which monitors the light shining through the windows and adjusts the outer row of interior lighting accordingly. We also installed free electric vehicle charging stations in our parking lot at our headquarters facility to encourage use of electric vehicles. Energy efficiency initiatives in 2021 were prioritized in response to pandemic regulations and budgets. Projects included: ■ Optimizing one of our data center's electrical load, which resulted in shutting off three computer room air conditioners (CRACs) leading to a Power Utilization Effectiveness close to 1.0 and more than 200 MWh of power savings annually ■ Upgrading or retrofitting motors in three HVAC systems with Variable Frequency Drives (VFDs) ■ Switching from R-22 refrigerants to more energy efficient R-407C in numerous HVAC systems ■ Upgrading one facility's lighting systems to LED lighting ■ Enhancing our headquarters facility's HVAC control systems 2019 2020 2021 KWH 100,000,000 80,000,000 60,000,000 40,000,000 20,000,000 0 annual electricity usage 2019 2020 2021 therms 1,500,000 1,000,000 500,000 0 annual natural gas usage
