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

•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 (and possibly other) distribution

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

• Integrated services possible to certain extent

• Industry differentiation regarding openness to new standards

• Compose realizable specifications
