Some Thoughts to Ponder
•
•
•
•
•
•
Do intelligent buildings exist?
What level of intelligence do they possess?
Is there a market for intelligent buildings?
Do intelligent buildings serve a real need?
Are they cost effective?
Are existing buildings capable of acquiring
intelligence?
• Is intelligent building a fad or a phenomena?

What is an Intelligent Building
PhD?
IB Attributes
•Features
•Processes
•Protocol(s)
•Performance
Paradigm Shift
The test of intelligence lies in ‘Performance’,
not technology including use of the best
materials, concepts and systems to meet the
needs of the owner, occupants and the
community. It is about ‘Process’ as well as
about building and the benefits lie in economy
and flexibility to meet the working and
sustainability needs.
Definition
• An intelligent building achieves and maintains
optimum performance by:
- automatically responding and adapting to the
operational environment and user requirements
- facilitating ready and cost-effective adaptation to
changes in user requirements, e.g. space
configuration and ways of working
Definition (cont.)
• Performance covers:
- health, safety, productivity, energy and environmental
impact, life cycle cost, marketability
• Operational environment covers:
- climate, occupancy, type of use, services
• Users are:
- occupant, owner, developer and agent
What do Customers Want?
• They do not want technology
• They want a building that:
-
works for them and their business
is economical to build and run
responds to their needs
is easy to adapt to new circumstances
is easy to use
• A building that performs optimally

Building Features that Affect IB Performance
• Shell, core and space
layout
• Amenities
• Materials and finishes
• Façade and cladding
• Structure
• Environmental systems
• Mechanical systems
• Electrical systems
• IT and communication
systems
• Fire suppression and life
safety systems
• Security systems
• Sensors and controls
Variable Frequency Drives
Pump, Fan & Compressor Laws
Q2/ Q1 = N2/N1
P2/ P1 = (N2/N1)2
kW2/kW1 = (N2/N1)3 eg kW2 = (1200/1800)3; kW2 = 30% of
kW1 (This translates into a power saving of 70%)
Efficiency Measurement Scale
Leadership in Energy and Environmental
Design (LEED)

Summary
• Considering users and their culture are key
• Innovative technologies must be justified
• Assessment method(s) for IB’s must be clearly
defined and agreed to with the Client
• Intelligence depends on meeting good practices
and not on amassing sophisticated devices
• Flexibility, Scalability, Maintenance and
Commissioning
• Performance, performance, performance
