Building Intelligence

• Intelligent building (IB)
• first coined in USA in early 1980s
• its definition/model is evolving
• automated buildings (1981-85)
• responsive buildings (1986-91)
• effective buildings (1992-)
• development of IB
• closely linked with computers and information
  technology (IT)
• but, IB ? high-tech building

4
Building Intelligence

• Major IB features
• automatic reactions (adjust internal conditions)
• effective communication IT management
• responsiveness to changes
• Integrated pyramid
• single function/dedicated systems
• multifunctional systems
• integrated systems
• computer integrated building

5
Building Intelligence

• IB in Europe study
• IB provides a responsive, effective and
  supportive intelligent environment within which
  the organization can achieve its business
  objectives. -- DEGW (1992)
• 3 main goals
• building management
• space management
• business management

6
Building Intelligence

• An intelligent building is one that doesn't make
  the occupants look stupid.
• maximizes the efficiency of its occupants and
  allows effective management of resource with
  minimum life costs
• more responsive to user needs and has the ability
  to adapt to new technology or changes in the
  organizational structures

7
Goals - minimise environmental impact - use
resource efficiently - be ecologically sound -
ensure healthy environment
Goals - building management - space management -
business management
Green Building (GB)
Intelligent Building (IB)
Information Technology
Environmental Sustainability
- building life cycle - efficient building
systems - effective management use - integration
8
Intelligent and Green

• Key issues for intelligent buildings
• site (access, local amenities, car parking)
• shell (thermal strategy, structure, floor layout)
• skin (services strategy, solar control)
• building services (HVAC, small power, cabling)
• information technology (communication, space
  management, network)
• Criteria business value/benfits, efficiency and
  effectiveness

9
Intelligent and Green

• Common objectives
• responsive (to user needs / to climate)
• efficient (building design systems)
• effective (operation management)
• better integration (with IT within systems)
• Trends
• smart buildings and Internet connectivity
• sustainability in business (quantifying the
  benefits)

Smart Car
Smart Green Building
- light compact - low-drag design - fuel
efficient - low emission - 95 recyclable -
efficient accessories - friendly factory
- energy efficient - use renewable energy - green
building materials - low environmental impact -
responsive to climate/site - responsive to user
needs - healthy environment

IB_at_Work

• Office space and commercial buildings
• speculative offices (USA or European)
• organizational/functional requirements
• impact of IT and business strategy
• Major systems
• building automation system (BAS)
• office automation system (OAS)
• communication automation system (CAS)

13
IB_at_Work

• Typical features
• building control energy management

IB_at_Work

• Current and future development
• new ways of working
• more interaction
• more collaboration (physically or electronically)
• more individual autonomy
• new patterns of space use
• more group spaces
• more shared spaces
• more space for concentration
• more intermittent space use

18
Future office space (intelligent? green?)

IB_at_Home

• Present technology
• phones and intercoms
• home automation
• audio distribution (e.g. hi-fi speaker)
• video distribution (e.g. TV)
• video surveillance (e.g. security)
• structured wiring
• home theater, game station
