Self -Aware Systems
• Should have good understanding of its current “State”
• Ability to measure all important parameters across sub-systems
• Sense where it makes sense
• Should be able to perform as per expectations
• Pro-actively and not just reactively
• All stake holders including itself
• Should be able to anticipate issues and get help
• Get things Fixed things before it breaks
• Get timely outside help
• All sub-systems should work with each other in co-ordination
• Not just a top level integration
• Leverage from each other
• Adaptable and Flexible
• Should respond and adapt to immediate and long term changes
2. The Best Self Aware System is ?
Can modern buildings become Self-Aware Systems ???
3. All the recent advances in Technology should make it possible
but
Technology has to be applied for the right problem in right context

Technology Landscape
Fundamentally new technologies
Or
Old wine in New Bottle ?
But we know these technologies existed for years
5. Current Buildings Systems
• Buildings are large Heterogeneous systems
• With very diverse sub-systems
• Each system is automated as an independent sub-system but
• Integrated at the top level
• Very little cross-leveraging between sub-systems
• One System does fully understand the other system
• Sensing and Control need more flexibility
• Wired and Electro-Mechanical Control System
Sensing Challenges
• Typical sensing is a single point sensing
• E.g. Thermostat in work-station area of a commercial buildings
• Needed: Distributed Sensing
• Technology/Cost limits placement of sensors at right places
• E.g. Lux sensor in the ceiling or Temperature sensor in a corner of a room
• Needed : Sense where it makes sense, Lux sensor on the table
• Typical sensing is single Parameter sensing
• E.g. Temperature for HVAC
• Needed : Temperature, Occupancy, CO2, PM2.5
• Local v/s Aggregated sensing
• Air Quality is both local and aggregate phenomenon
• Needed: Both local and Aggregated Sensing
6. Control Challenges
• Hard-wired controls with some flexibility
• Most of the control system are PID based: e.g. VAV Controllers
• Needed: Adaptive control with complete flexibility
• Linear, Single parameter
• General purpose linear PIDs which work on single parameter; e.g. CFM
• Needed : Multi-parameter; Non-linear control systems
• Demand-Response Time
• Electro-Mechanical Systems have significant lag in Demand-Response
• Needed : Instant response to dynamically changing requirements
7. System Perspective
Some Practical Aspects
• Cost of Technology
• Typical Questions : Why should I pay for this ?
• Ideally Technology should pay for itself
• Who is benefitting and Who should pay ?
• Builder / Promoter / Occupant
• Who is your ultimate customer ?
• Installation & Retro-Fit
• Installation & Infrastructure impact should be minimum
• Specially important for Retrofit buildings
• Easily upgradable as technology advances

9. The Opportunity
• Rising energy prices
• 60% of energy utilized for lighting & HVAC
• Typical occupancy at work place is 60-65%
• Modern buildings have a lot of day-light available
• Sporadic usage of space post regular hours
• Temperature monitoring & Control Sub-Optimal
• Green Buildings & Carbon foot print reduction
