2. • Intelligent buildings are buildings that through their physical
design and IT installations are responsive, flexible and adaptive to
changing needs from its users and the organizations that inhabit
the building during it's life time.
• The building will supply services for its inhabitants, its
administration and operation & maintenance.
Definition
The building will supply services for its inhabitants, its
administration and operation & maintenance.
• The intelligent building will accomplish transparent 'intelligent'
behaviour , have state memory, support human and installation
systems communication, and be equipped with sensors and
actuators.
3. What is an intelligent
building?
A building…
• who’s systems are self reliant
• with sensors relaying data
• with sensors relaying data
• that uses the latest technology
• that is the future of buildings
4. Objectives of intelligent building
• Energy management
• Indoor Comfort
1.Thermal comfort
1.Thermal comfort
2.Visual Comfort
3.Indoor air quality
5. • 85% of the energy used in buildings is for low temperature
applications such as space and water heating
• Building designs involving clean and efficient technologies
help to reduce energy consumption as well as to provide a
better quality of life for citizens.
Energy management
better quality of life for citizens.
• Energy consumption in building is required for the following
uses:
1. Heating 2. Cooling 3. Ventilation 4. Lighting
6. Equipment and machinery 7. Domestic hot water
6. Indoor comfort
•Comfort is defined as the sensation of complete physical and mental
well being.
•Thermal neutrality, where an individual desires neither a warmer
nor a colder environment, is a necessary condition for thermal
comfort.
comfort.
The factors affecting comfort are divided into personal variables:
1. Activity Clothing
2. Air temperature,
3. Mean radiant temperature air velocity
4. Air humidity
7. Present
technology
–Phones and intercoms
–Home automation
–Audio distribution (e.g. hi-fi speaker)
Audio distribution (e.g. hi-fi speaker)
–Video distribution (e.g. TV)
–Video surveillance (e.g. security)
–Structured wiring
–Home theater, game station
8. • Building Energy Management Systems aim to optimise the
use of energy in buildings by maintaining at the same time
the indoor environment under comfort conditions.
• Practically, a BEMS is a computerised system that attempts
to “control” all or some of the energy consuming operations
Building Management Systems
to “control” all or some of the energy consuming operations
in a building:
– HVAC systems (Heating Ventilating and Air Conditioning)
– Lighting systems (natural and artificial)
– Indoor climate

12. 3 Main goals
• Building management:
–Building automation and the physical environment
• Space management:
–Building’s internal space & operating costs
–Building’s internal space & operating costs
–Capabilities & flexibility of the building to
accommodate changes, personal moves &
connectivity
• Business management
–Management of the organization’s core business
13. Components of an IB
• Integration of various building systems
– Energy management system
– Lighting management system
– Security systems & fire safety
– Security systems & fire safety
– Telecommunications & office automation
– Local area networks (LANs)
– Cabling management
– Intelligent maintenance mgt. system (IMMS)
– Computer aided facility management (CAFM)
14. Components of an IB
• Four main aspects:
– Facility management
• Takecare & maintain various functions for occupant
comfort & operation
– Information management
– Information management
• Office automation (OA), LAN, wiring
– Communication
• Tel/Fax, e-mail, video telecommunication
– Control
• DDC, building automation system
15. Components of an IB
• Critical performance qualities
– Functional or spatial quality
– Thermal quality
– Thermal quality
– Air quality
– Aural quality
– Visual quality
– Building integrity
19. Components of an IB
Early warning systems
like smoke detection
systems,
detects the fire at a very
early
early
stage and pinpoint to the
caretaker where it is occurring,
so that the fire is extinguished
locally through manual fire
extinguishers
20. Components of an IB
Tosense different areas &
locations in order to gauge
& monitorthese gases
& monitorthese gases
This activates the ventilation
& make the environment
safe and poisonless
Required in places like
kitchen ,car parking, IT
companies
21. Components of an IB
VENTILATIO
N
HEATING
H & AC CONTROL:
It helps BAS to allow the
building owners to have more
control over the heating &
AIR
CONDITIONING
control over the heating &
cooling units.
Owner can manage the
system in one single touch
using remote control by
pneumatic controls.
22. Components of an IB
VENTILATIO
N
HEATING
UNAUTHORIZED MOVEMENT
OF ANY PERSON:
It helps in identifying the
AIR
CONDITIONNG
It helps in identifying the
problems with security policies
& theft when a person trying
to intrude Unauthorized access
