Objectives Use one single IP-network for all data communication in buildings Identify services Compose specifications of infrastructure Commercial buildings Residential buildings

Benefits Integration and rationalization of building management Adoption of IP-based services Vendor independence Create standard building automation platform Less canalization space

Considered Services Computer communication Telephony Television Access control and security Fire detection and alarm Heating, ventilation and air conditioning Lighting control Individual measurement of electricity and water Bulletin system

Computer communication Telephony Television Access control and security Fire detection and alarm Heating, ventilation and air conditioning Lighting control Individual measurement of electricity and water Bulletin system Communication over IP

Specifications Services organized into subsystems All subsystems must interface to IP backbone IP distribution networks on each floor Subsystem communication within floors: Solely IP IP to intermediate level Open building automation protocol Proprietary building automation protocol

General Model

Solely IP Internet Firewall/router IP backbone IP distribution network

IP to Intermediate Level Internet Firewall/router IP backbone IP distribution network Other distribution network, open or proprietary protocol Gateway

Open Building Automation Protocol Internet Firewall/router IP backbone IP distribution network Other distribution network, open protocol Gateway

Proprietary Building Automation Protocol Internet Firewall/router IP backbone IP distribution network Other distribution network, proprietary protocol Gateway

Challenges Lack of IP-based field devices High cost of TCP/IP stack Industry skepticism towards open standards Solution: Wait or demand improvement Data representation Solution: XML Security Solution: VLAN

Conclusions and Recommendations Integrated services possible to certain extent Industry differentiation regarding openness to new standards Hampered market communication Solution: Central competence aggregation function
