I work in an IoT startup that is upgrading commercial HVAC to support smarter energy management. It's shockingly easy to save 10-20, sometimes up to 50% energy just by scheduling and occupancy-based control. All these huge, empty, cold rooms in the malls and office buildings are wasting a lot. Commercial buildings are contributing up to 40% of all greenhouse emissions, so if we reduce that by 20%, that's already a 8% global win. It is software + hardware though.
