72% of electrical consumption, 40% of total consumption, 50% with construction, 42% of GHG footprint Commercial building consumption 2x , 1.5x more by 2025 [NREL] Where the coal is used The prime target of opportunity for renewable supplies Save the world Renewable energy consumption Electricity source Software Controllable!
The sMAP library many different underlying sensors and stacks More then 100 instruments, > 500 ACme plug-load meters channels of high-resolution data It’s easy: simplest service is ~3 lines of Python
Real-Time Occupant Control Live on two floors 137 distinct users Over 50% energy savings (Krioukov et. al., proc. BuildSys ‘12)
