Buildings: Big Data Potential

– Energy consumption – System peaks – Automated controls – Occupant comfort – Maintenance requests – Secure access – File storage

Building Data

Granular energy data and dynamic pricing – Reduced supplier costs – Deferred network investment – Cheaper energy bills

Example: Domestic DSR

Significantly more complex systems – Predict demand reductions – Respond to automated network signals – Deliver agreed demand reduction – Monitor building performance – Communicate benefits to engage occupants

Example: Non-domestic DSR
