Software Defined Buildings

DESCRIPTION

Explore the future of architecture through software-defined and reconfigurable buildings. This article discusses building applications, key differences between residential and commercial spaces, and the balance of benefits against potential drawbacks. Learn about APIs that empower occupants to program their environments, consumer-centric mobile apps for enhanced living experiences, and effective integration of HVAC systems with smart technologies. Delve into fault detection, baseline deviations, and the need for standardized models, all aimed at optimizing building efficiency and occupant comfort.

Presentation Transcript

  1. Software Defined Buildings • What are building applications? • Reconfigurable and responsive buildings • How do software-defined and reconfigurable homes differ from commercial buildings? • Do the benefits of reconfigurable physical spaces outweigh the drawbacks? • What is the API for occupants to program the building?

  2. Possible applications • Consumer-centric, mobile applications • Mute tv when the phone rings • Wire HVAC system to the windows • Drive efficiency and reliability • Fault detection – disconnected valves, broken economizers • Baseline deviations • Model-predictive

  3. Isolation and failure as metrics • Failure and sub-optimality are already very prevalent • What would it mean to fail in a meaningful way? • Hard to drive the building into a truly “unsafe” state • Exceptions are life-safety systems: fire, other alarms, doors (in a fire)

  4. Information plane: mobile data • Push from mobile sensors and data • Integrate into models, geosystem, how to find things?

  5. Modeling

  6. additional layer of complexity not in a computer OS Nguyen Thi Hoang Lan, http://cnx.org/content/m29708/1.1/

  7. Mapping Layer? • Computer OS doesn’t deal with differing bus architecture • Proposal for mapping layer: • Derive standardized higher-level features from sensor data • occupancy? • temperature map? • Standardized representations of floors, zones? • Need for reliability, accuracy estimate? • Perform control and arbitration at a higher level of abstraction • Scenarios for building control modes • “emergency,” “night” • Customization of lights, energy, user interface
