3 3 most important reasons 1. Seeing is believing Gives the opportunity for Danfoss customers to experience our products in real life. 2. Relocation of Danfoss Solar Inverter business from 3 different locations to one location in Nordborg. Gives the opportunity for Danfoss RD engineers for testing new inverters in large scale plants. 3. Danfoss climate strategy is to reduce CO2 emissions by 25% by 2025 and increase the share of renewable energy by 25%. 3 Real Estate

4 Danfoss climate strategy > CO 2 Climate, environment and natural resources Danfoss aims to reduce CO 2 emissions by 25% by 2025 and increase the share of renewable energy by 25% compared to the group level in Real Estate

5 Energy savings Based on the climate strategy 3x25, Danfoss has decided to implement energy screenings of the 15 largest factories over a 3 year period. The 15 largest factories represent about 75% of Danfoss energy consumption globally. The goal is to achieve 12% savings with a simple payback period of 3 years.
