We must develop the “magic” to take our automation interfaces to the next level in an elegant convergence model.

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.

slide21

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. 

slide22

From a worker performance perspective it is extremely wasteful that we arenot aggressively pursuing suchindividual comfortcontrol connections. 

why a web based interface
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.
slide25

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.

if we do not change changes will come from outside our industry
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
Avoiding Network Clutter
  • Standardized protocols
  • Use managed network hardware
  • Know the domain of use
  • Derived vs collected data
the osi model
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
