Lecture 09 - Intelligent Buildings
2Contents
- Building Intelligence
- Intelligent and Green
- IB at Work
- IB at Home
3Building 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
4Building 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
5Building 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
6Building 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
7Goals - 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
8Intelligent 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
9Intelligent 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)
10?
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
11Making cars like we build houses?
12IB_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)
13IB_at_Work
- Typical features
- building control energy management
- lighting management
- addressable fire alarm
- structured cabling
- voice/data/image communication
- office automation

16Integration controls network from different
buildings
17IB_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
18Future office space (intelligent? green?)
19IB_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
20IB_at_Home
- Future home
- home networking
- Internet appliances
- webcam, web phones
- e-books, video walls
- home office
- virtual clinic/hospital
