Abstract:
Building automation and control systems (BACSs) have
become increasingly innovative since their introduction
of the open ANSI/ASHRAE Standard 135-1995 BACnet - A
Data Communication Protocol for Building Automation and
Control Networks standard. The integration of BACSs with
enterprise information technology and networking
infrastructure will facilitate new customer services
that increase efficiency and decrease costs. The ASHRAE
Research Project 1011-1999 Utility/Energy Management and
Control System (EMCS) Communication Protocol Requirement
describes nine operational information services
currently considered by various working groups: (1)
revenue meter reading (electricity, gas, water, heating,
and cooling energy); (2) quality of service monitoring;
(3) real-time pricing transmission; (4) load management
services; (5) on-site generation supervisory control;
(6) energy efficiency monitoring; (7) weather reporting
and forecasting services; (8) indoor air quality
monitoring; and (9) dynamic demand bidding into a power
exchange. Each service generates and exchanges
information with varying effective lifetimes, bandwidth,
and security requirements. This research project
sponsored by the National Institutes of Standards and
Technology (NIST) and performed at the Pennsylvania
State University focused on the security aspects of
these proposed operational services. We focused on two
specific aspects of the BACnet standard, namely BACnet
Broadcast Management Devices (BBMDs) and the Network
Security clause (Clause 24) of the ANSI/ASHRAE Standard
135-1999.
