Next Wave of Convergence: BAS along with Voice, Video & Data
If the design of the converged network occurs early enough in the building design and construction life-cycle, there are actually capital expense savings.
Sinclair: If we assume that Building Automation and Physical Security systems (such as surveillance and access control) are moving towards convergence with voice, video and data, how are companies like Cisco Systems handling this internally?
Clute / Lavazza: We have had segments of our Building Automation System (BAS) over our Corporate IT Network since 1999. We collaborated with our IT Infrastructure and LAN Operations groups to detail the requirements such as the equipment we would be connecting to the Corporate IT Network, bandwidth impact, security and static IP address requirements. The IT Infrastructure and LAN Operations groups are responsible for approving device connectivity and static IP address assignment.
Sinclair: How does the CIO / IT organization address the concerns of Facility Managers and Building Engineers that they may lose control of their systems to the IT group, as BAS moves to the IT backbone?
Clute / Lavazza: Communications and collaboration between IT Infrastructure and Building Automation System engineers will evolve and grow. The dependencies will drive these relationships to ensure standards and guidelines are followed and new requirements are communicated and understood. Open dialogue between the groups with regard to intent and future direction will ensure that both groups’ objectives and initiatives are maintained.
Sinclair: Realistically, how long will it take for the industry to produce native IP devices (IP-enabled endpoint devices such as VAV controllers, light fixtures, etc.) that will allow full migration to a converged IT network?
Clute / Lavazza: This could take a few years. The amount of information that is collected or passed to these devices is small and the bandwidth requirements are minimum. IP connectivity to these devices is like taking a drink from a fire hose, but as technology advances and price points drop, these device will eventually be IP enabled.
Sinclair: What are the tangible cost benefits associated with BAS convergence over the IT network, in other words, what are the “bottom-line” reasons that might influence an owner of a building to invest in moving their BAS systems to an IP-backbone?
Clute / Lavazza: The cost of implementing a converged BAS system over an IP network does not necessarily mean greater capital investment. If the design of the converged network occurs early enough in the building design and construction life-cycle, there are actually capital expense savings. If the design of the converged network occurs late in the design cycle, then yes, there are additional costs associated with changes to the structured cabling system and building control systems. The tangible cost savings that can be attributed to converged BAS over IP, if adopted early enough in the building life cycle, include the following:
Potentially lower cabling costs for the HVAC control systems by using wireless thermostats and PoE (Power Over Ethernet) control circuits.
Lower energy costs associated with improved optimization, scheduling and coordination
Improved comfort due to individual control of lights and HVAC systems through web-based control devices on their PCs, hand-held PDAs or IP Telephone control consoles – leading to greater employee productivity
Plug and Play integrated Technologies - The key to adapting building automation subsystems and a BMS network to tenants is plug and play integrated technologies. The ideal system offers cost effective turnkey solutions for building owners. This translates into reduced costs for modifying a space as users’ requirements change. Turnkey solutions are defined as workplace and building environmental changes required for accommodating each new user (or existing user with revised operating needs). This allows for a “box or briefcase” move rather than a retrofit or renovation with each new user.
Reduction in technological obsolescence by facilitating the easy and economical introduction of new technologies, or replacement of dated technologies.
