the ‘smart’ in smart buildings
Building efficiency services & ICT environment

10. ARTIFICIAL INTELLIGENCE (AI) :
BASIC BUILDING BLOCKS
• 1. MACHINE LEARNING
Machine learning is an application of artificial intelligence (AI) that provides systems the
ability to automatically learn and improve from experience without being explicitly
programmed. The primary aim is to allow the computers learn automatically without human
intervention or assistance and adjust actions accordingly.
• 2. DEEP LEARNING
Deep learning is a type of machine learning that trains a computer to perform human-like
tasks, such as recognizing speech, identifying images or making predictions. Instead of
organizing data to run through predefined equations, deep learning sets up basic parameters
about the data and trains the computer to learn on its own by recognizing patterns using
many layers of processing.
• 3. NATURAL LANGUAGE PROCESSING
Natural Language Processing (NLP) is a key building block that will help computers learn,
analyze, and understand human language
• 4. NATURAL LANGUAGE GENERATION
Natural language generation (NLG) is the use of artificial intelligence (AI) programming to
produce written or spoken narrative from a dataset
5. VISUAL RECOGNITION
Image recognition is used to perform a large number of machine-based visual tasks, such as
labeling the content of images with meta-tags, performing image content search and guiding
autonomous robots, self-driving cars and accident avoidance systems.

AFDD is an automatic process by which faulty operation, degraded performance,
and failed components are detected and understood. The primary objective is
early detection of fault and diagnosis of their causes, enabling correction of the
faults before additional damage to the system, loss of service, or excessive energy
use and cost result. This is accomplished by continuously monitoring the
operation of a system, using AFDD processes to detect and diagnose abnormal
conditions and the faults associated with them, then evaluating the significance of
the detected faults and deciding how to respond. For example, the temperature
of the supply air provided by air-handing unit (AHU) might be observed to be
chronically higher than its set point during hot weather. This conclusion might be
drawn by a trained analyst visually inspecting a time series plot of the supply air
temperature .Alternatively , a computer algorithm could process there data
continuously ,reach this same conclusion, and report the condition to operators
or interact directly with a computer-based maintained management
system(CMMS) to automatically schedule maintenance or repair services.

27. Digitalization
• Digitalization now not only stretches across the globe
but also across the broad range of building
disciplines and beyond.
• Today, data can be gathered from safety and security
systems, HVAC equipment and controls, energy
efficiency programs together with lighting and
power.
Building efficiency services & ICT environment

28. The new digital world
• Intelligent sensors, actuators and similar devices supply a
wealth of data which until now has mostly been unused.
• Intelligent evaluation using big data applications can now
be used to combine these massive but unstructured
amounts of data into transparent information which in turn
can be feed into linked performance indicators in real time.
• Smart algorithms can easily evaluate trends and recognize
patterns in user behavior or consumption, thereby enabling
informed decisions, predictive strategies and continuous
optimization.
• This, together with sophisticated self-optimization
functions, gives buildings a central nervous system making
them smart.

29. Transformation process
in the new digital world
• Building digitisation is here and data can be leveraged to
improve efficiency and drive down costs
• The digital transformation will lead to new and changing
business models
• The software becomes a central factor with openness and
transparency being key. Closed and proprietary systems will
be big losers
• Partnerships between traditional industrial enterprises and
large IT players
• Network of partnerships and alliances, companies are
interconnected in ecosystems but at the same time act as
competitors in the market

Progress is now accelerating by pairing technology and
analytics with building experts and service.
