1. Evolution of the Intelligent Building

Welcome once again -

2. What is an Intelligent Building?
“One which provides a productive and cost-effective environment through optimization of its four basic elements, ie structure, systems, services and management and the interrelationships between them.”
- Intelligent Building Institute of USA
So, what is a intelligent building?
We can define this in many ways but here is a quote from one of the members of the intelligent buildings institute of America which sums it up nicely.
“A smart building is one that achieves significant energy savings, by taking advantage of improved technology and materials in terms of structure, appliances, electrical systems, plumbing, and HVACR.”
This provides us a nice overview of what we have been and will continue to strive for.

Energy costs
Building automation
DDC Controls
Proprietary Protocols
Enabling technologies & developments
What is driving the evolution towards a more connected building?
There are three principal elements driving this:
Underlying or Enabling technologies, these are principally standards for communication and low cost microcontrollers.
Cost of Energy: July 2008 was the absolute peak of oil prices $145 / Barrel, compared to the average price enjoyed in the 90’s of $30-40
Challenges associated with running operations within large facilities.
Likely a line missing which is the technological trends in the consumer market: Iphone, Android, App store – This earliest signs of this gaining momentum were in 2007 with the introduction of the Iphone, the resto of course quickly followed. The introduction of these changed everything and have all had a profound effect on the expectations of the occupant and continue to do so. This is obviously having an effect on the infrastructure we specify and apply simply due to the sheer amount of data.

Energy and technology have a changed the way we create and apply building systems.
In our move toward a more intelligent facility or building, energy is providing us the want and need and technology is assisting us deploy smarter, integrated systems using a more holistic approach.

So there is some history to cover which I will walk you through over the next few minutes in an abbreviated manner:
Yesterday:
Primarily standalone systems focused on their respective domain; Comfort based temperature, access, lighting security etc.
These domains had their own respective trades which delivered these systems, they spoke their own protocols and were serviced by different entities. Integrating these were often expensive and required gateway devices.
Though they were operated by the same occupants and maintained by quite often a single stationary engineer.

Today – Well the story is a little better but not without challenges.
Systems focus has shifted from comfort only to balancing energy comfort and sustainability. They are getting a little more sophisticated in terms of delivering services with exception base service (event driven) thus reducing operational costs.
Some facilities are integrating using gateways / protocol bridges or standardizing on a single control network protocol, but these rarely cross disciplines so silo’s still exist in new construction today.
Open protocols in the HVAC space are pervasive: BACnet / Lontalk / Modbus, all of these are used at one system level or another on field devices, controllers etc.

Tomorrow – Here’s where the story is changing in a more profound way, much of this is of course unwritten but we’ll give it a shot.
Expectations for user interface and experience are changing – mobility, now
Devices are becoming more capable, controlling not only HVAC equipment but lighting and blinds within a single space thus making integration a story of the past.
Fewer, more intelligent devices are being installed, on IP networks.
These devices are using standard web API’s and commands rather than industry or building specific interfaces.
Refining this a little further will lead us to a more concrete conclusion though.

So lets refine the story a little further….

9. automated & integrated at building level
Today
automated & integrated at building level
Operational savings via global logic
Aggregated data
Less technicians
Efficiency becomes a priority
Synergies reduce energy wastage
Energy dashboards
Environmental responsibility gains traction
Share sustainability initiatives
In the context of the modern building, today we are most focused on three major categories:
Energy efficiency
Climate control
& most recently our sustainability efforts, or carbon footprint of the facility.

10. Networked Systems HVAC Lighting Shades/Sunblind Unified at room level
There has been some progress in terms of unifying systems, (CLICK) primarily at the zone or room level. Principally the drive for this has been to increase comfort and energy savings this side effect of this however has improved the user experience in terms of both comfort and convenience.
Mobile applications are becoming available to provide a simplified way for the user to control the single room system.

11. Unified building control strategies can result in demonstrated savings in excess of 30% on HVAC and up to 60% on lighting.
- Hannover University of Applied Sciences and Arts
Unifying systems, or getting the any one system has enormous benefits from and energy perspective. Here’s an example based upon a study done by Hannover universities Applied Sciences department. The result of which determined that simply eliminating silo’s could result in energy savings of up to 30% on HVAC applications and up-to 60% when applied to lighting and HVAC as a single unified system.

12. Tomorrow The Connected System
HVAC
Lighting
Shades/Sunblind
Access Control
So, where do we go from here.
Doing more with less has been the message to date. But to truly achieve this we need to re-tool the entire infrastructure of devices the industry offers currently. We need to do this because the technologies we have offered just a short time ago can just barely deal with the Data exchange necessary to really efficiently manage all of the disciplines within the next generation of facilities. The communication mediums we are using at the moment are changing too. Connectivity options, IT standards as well as security.
HVAC
Lighting
Shades or Sunblinds
Access control
CCTV
All of these disciplines are becoming standard as part of the connected building. With this comes the data, a more complex user story and a place or repository to store and manipulate the data to present to different stakeholders.

13. a single system approach
Connected Systems
a single system approach
Convergence with IT infrastructure
Manage one network
No additional wiring
Minimize impact on the building’s envelope
Use of existing infrastructure
Scalability
Improved responsiveness
Ease of interaction
Prepares for Internet of Things building
Access key information anywhere, any time
With the connected building, we are moving even further towards a single system approach, throughout the facility.
Our clientele is changing, becoming more sophisticated.
No longer are we focused on any one single pillar. We must consider user cases for the system from the end user perspective. Specifications for the building need to reflect this new clientele and what they are expecting from their indoor environment.

14. 96% of the global business leaders surveyed expect their businesses to be using IoT technology in one form or another by 2016.
Support this hypothesis are the results from the Economist which tells us that over 90% of business leaders expect to be using IoT technology in one form or another by next year.

the best way to predict your future is to create it
Cloud computing, mobility , further system consolidation , more applications & interconnectivity are likley what we can expect.
In closing, would like to add that all of this in room are poised to become the experts and have the unique opportunity of defining what our next generation buildings and systems look like.
Thank you.
