You will not find a smart building in North America. You might think you can, but after this post, you'll think twice. First things first. "How do you define 'smart'?" you ask. Great question. How about this for starters:
- HVAC and power consumption is regulated according to the number of people in the building
- Clear understanding of how building services are being consumed; tenants are charged accordingly
- Smart infrastructure recognizes each individual as they walk into rooms
- Building services tailored to personal preferences
- Instant access to required IT and communications systems
PS - You can do all this today. Utilizing embedded Internet technologies, deploying inexpensive chip sets, and changing the way we manage electrical and data systems, it is possible to transform the way we interact with built environments.
The Infrastructure
Every building consists of a 4-layer dip:
- Layer 4: Software
- Layer 3: Products
- Layer 2: Technical Infrastructure (digital/mechanical/electrical systems)
- Layer 1: Building framework
Each layer has its own life span. The software, at level "zero" becomes obsolete as it comes out; the products have roughly a 2-year life span; the technical infrastructure 10, and the building structure itself, 50. The importance of the dip is that each layer needs to be embedded in the layer below it. As we will see, this integrated infrastructure will allow building owner to switch from a function-driven, device-oriented platform to a service-oriented platform. This will increase a building's value by reducing capital and labor and streamlining operational efficiencies
The smart-building platform
Compare IT equipment to traditional building devices (e.g. lamps, blinds, elevators, security and access-control systems). IT devices perform better - almost by a factor of 10,000. However, in a typical built environment there will be 10 times as many devices per person that control and manage the building than IT devices per person. Owners must take this into account when assessing what they should be charging for smart-building services.

The answer lies in the IP
There are millions of traditional electrical devices installed in built environments today - this is a huge obstacle to overcome. In order to create a smart building, consistency must be brought to the user interface and data and communication standards must be normalized to the IP.
If you can do this, then adding a new device becomes and issues of plug-and-play. This WILL have an impact on maintenance costs and energy management. Think of the amount of money spent on keeping appliances on standby. If you could manage a simple television set (consumes 20 watts in standby mode) via an Internet-based communications infrastructure you significantly cut energy cost (down to 0.2 watts).
To solve this problem, a high-voltage/low-cost chip can be integrated into any electrical device and networked across the existing electrical wiring. This chip would allow users to control devices via an IP connection so that they can turn devices on and off, switch channels on a TV, open and close window blinds, control individual lights, etc.
Simplify the process
As I've spoken about many times, the current building process is a major challenge today and especially so in implementing IP-based building control and management. Electrical engineering and technology engineering are following two different design, procurement, and construction paths. When utilizing existing electrical wiring, electrical engineering is not impacted - there are no new tools to learn, no programming, no training, no cabling. In new construction, capital and labor costs are reduced.
Clarity Found
Today we think in terms of devices. This mindset needs to shift and we need to focus on the network. Devices today should be classified as "sensors" or "activators". Where sensors pick up images, sound or building operations such as cameras, activators react to these inputs - they include multi-functional displays to show images and light bulbs and activate heaters to provide a healthy and comfortable environment.
Setting up your digital environment in the form of sensors and activators allows you to organize your device free from the constraints of software. A telephone, for example consists of a mic and speaker (which can also be used as an mp3 player), while the "phone" itself is software - think iPhone.
Example: Individuals will be able to turn on the lights open and close windows an access video through just one device.
Make it happen
The key to adopting this concept is the fact that a smart building is built around one generic chip that is mass-produced and therefore, relatively inexpensive. No new skills are required by electricians, common interface makes for a comfortable migration path for users, so there is likely to be little resistance to adoption.
Today's buildings are managed from a functional perspective; we need to move to a services philosophy creating significant energy savings, operational efficiencies, and a far more attractive environment for building occupants.
Just a question before I end - Any smart buildings in North America?
