Buildings With Their Own
Internet Identity and
Address
Where should we locate our
Web-Based Facilities
Operation "WBFO"?
Documenting the Design
Variance
Buildings are seldom operated
as they were originally
designed.
We must develop the
“magic” to take our
automation interfaces to
the next level in an
elegant convergence
model.

It is all about a
better interface with the end-user.

I predict a very strong movement to "occupant
integrated" HVAC controls within the next decade.
My prediction is that by the second decade of this
century, most class "A" office spaces will be required
to offer individual control of thermal and lighting levels.
This integration will most likely be Internet based.
Occupants are connected to
wide area networks, including
the Internet, and yet almost
none of them can connect to
their local comfort system to
request changes in thermal or
lighting levels in the space
they occupy.
From a worker performance
perspective it is extremely
wasteful that we are
not aggressively
pursuing such
individual comfort
control connections.
WHY A WEB-BASED
INTERFACE?
•
•
•

•
Easy access.
Cost of ownership.
Ease of installation and configuration.
Common 'front-end' to dissimilar systems.
Extended life of existing EMS.
Scalable.
We are not talking about
viewing our old systems
through a Web browser; we
are talking about total
product, design, control,
and mechanical/electrical
equipment integration.
Super Operators
"The Birth of the
Super-Operator"
and creating their support
network.
Have you seen the
new CABA
Technology
Roadmap for
Intelligent
Buildings?
If we do not change,
changes will come
from outside our
industry.
The real danger for our industry is if we do not grow
rapidly enough to provide this value added service there
is a host of "ISIT's" (Information Systems and Information
Technology) types who will.

Avoiding Network Clutter
• Standardized protocols
• Use managed network
hardware
• Know the domain of use
• Derived vs collected data
The OSI Model
Layer 7: The application layer...is where communication
partners are identified
Layer 6: The presentation layer...is usually part of an
operating system
Layer 5: The session layer...sets up, coordinates, and
terminates
Layer 4: The transport layer...manages the end-to-end
control
Layer 3: The network layer...routing of the data
Layer 2: The data-link layer...synchronization for the
physical level
Layer 1: The physical layer...conveys the bit stream
