IP Integration for building services
• Lifecycle, consultancy led– Strategy and business case support– Concept and detailed design– Procurement and implementation
• Key areas– Revenue generation / cost reduction– Audio visual and collaborative technology– IP data networks (wired/wireless/mobile)
• Main projects (large IT / audio visual influence)– Offices and data centres– Schools, colleges, universities– Hotels, sports venues

This is not IP integration
This is not IP integration - converged
• Systems communicating with each other via IP to automate– Sharing of information between applications and
database(s)– Not sharing of status (such as on/off - often achieved via
other means – relay/similar) • Real world requirements
– Location (alarm and CCTV, asset tracking)– Multi-function cards (access, lifts, printing, vending)– Occupancy / energy? (better by other means?)
• Common system management interface– Nice to have but difficult to achieve– Who do you call when something goes wrong?
What is IP integration then?
Case study
• Talking different languages– LONworks over IP– BACnet over IP
• Just because a protocol works over IP doesn’t mean it will talk with other protocols over IP
• Avoid ‘closed, proprietary’ protocols
Protocol language
• Real benefit of IP integration– Remote management (Opex)
• System aggregation• Information not in silo’s – can analyse / improve• Centralised control bridge
– IP is platform for ‘cloud’ based sensors• Benefits come with scale
– Scale does not exclusively mean big buildings• Lots of small buildings (campus / estates)
• Balance of benefit lies with occupier– Landlord has few incentives, except undermining the
ability for an occupier to manage• System architecture decisions taken at Cat-A impact Cat-B
Benefits of IP integration
• Landlord / Occupier– Who owns and maintains– Single tenant / multi-tenant building
• Thinking like a contractor not like an occupier– IP more expensive? (really…)– Occupier/operator attitude is most likely to be ‘why not
IP?’
• Applications and data network design
• Contractual responsibility
Design and delivery pitfalls
Application Demands Considerations
Telephony Minimal delay Quality of Service
CCTV View and record at same Multi‐casting (particularly across sub‐nets), frame rate

Applications and IP data network design
Many applications were not originally designed for IP networks but adapted.

Contractual responsibility
Who is responsible for making it work?
Management contractor is only a ‘management’ contractor
Case study
Case study
• What was the issue?– Lighting control application
• Lighting system worked by a lighting controller talking to all other lighting controllers (uni-cast mode)
• Large amount of lighting control traffic initiated by PIR’s• Uni-cast mode can lead to large ‘broadcast’ traffic which can
overwhelm lighting controllers due to the ‘buffer’ in lighting controllers being low capacity and this makes them fail

Traffic
Broadcast traffic rising
Light controller failure
• What initiates broadcast traffic in this instance?– Controller not installed– Data network switch mis-configured– Damaged IT cabling / incorrect patch– Hardware failure of a lighting controller– Power isolation resulting in a lighting controller turning off
• Blame game between contractors
Case study
• Solution (in this case)– Lighting control system ‘segmented’ such that only
lighting controllers that needed to talk to each other did • Lesson
– Consider applications– Have one party responsible
