The document discusses smart cities and how smart home technologies like KNX can help address energy challenges in cities. It begins by noting the rapid growth of cities and challenges they face regarding transportation, pollution, infrastructure, and more. It then discusses energy challenges around reducing emissions and fossil fuel dependence. KNX is presented as an open standard for smart home automation that can integrate lighting, HVAC, security and other systems to improve energy efficiency. Buildings using KNX have seen energy reductions of up to 80%. The document promotes KNX as a way to help cities become more sustainable through smart home technologies.

•KNX Advantage
•Q&A
OVERVIEW

3. SMART CITIES
The statistics tell a grim story. By year 2050,7 out of 10 people
on the surface of the earth will live in a city. Mega cities of
population exceeding 10 million dwellers is a new but growing
phenomenon and can be found predominantly in developing
economies.
Lagos is the third fastest growing city in the world.

4. SMART CITIES

5. SMART CITIES
Challenges of running most Cities are similar however
these are further accentuated by the large scale Mega
cities present. These include:
•Transportation
•Pollution
•Infrastructure
•Water supply
•Waste disposal
•Healthcare
•Security
In todays lecture we look at the challenge of Energy
Infrastructure and the emerging technologies being used to
address the energy deficit.

6. SMART CITIES
“Smart cities use information and communication
technologies (ICT) to be more intelligent and efficient in
the use of resources, resulting in cost and energy savings,
improved service delivery and quality of life, and reduced
environmental footprint–all supporting innovation and the
low-carbon economy.” Boyd Cohen

7. THE ENERGY
CHALLENGE
The most pressing energy challenge facing modern society
are the twin threats of Global warming and the imminent
depletion of fossil fuel stocks (oil, coal, gas).

8. THE ENERGY
CHALLENGE
•EU activities to reduce CO2 emission until 2020 (-20%)
•European standard EN 15232 Energy Performance of Buildings, Impact of
Building Automation and Controls
•Global Green Building Initiatives
•Public awareness to save energy and to protect our environment
•National Center for Energy Efficiency and Conservation, Nigeria

9. THE ENERGY
CHALLENGE
WHAT DOES ENERGY
EFFICIENCY MEAN ?
WHAT DOES ENERGY
EFFICIENCY MEAN ?
•using less energy to achieve the
same result.
• using the same amount of energy
to produce a better result.

10. THE ENERGY
CHALLENGE
% ENERGY = ENERGY USED/ENERGY
EFFICIENCY SUPPLIED

11. THE ENERGY
CHALLENGE
•Renewable energy technologies
•Low energy bulbs
•Variable refrigerant flow A/C
•Smart grid
•Smart home
Mega Cities require a different approach to meeting the
Energy needs since demand will always outstrip supply.
Building bigger power plants and wider roads is
unsustainable.
GAME CHANGERS

12. THE ENERGY
CHALLENGE
RENEWABLE ENERGY TECHNOLOGIES
•Solar Energy
•Wind Energy
•Biodeisel/ Biogas
•Small Hydro
•Wave Energy

13. THE ENERGY
CHALLENGE
ENERGY SAVING BULBS USE 33% OF THE ENERGY USED BY INCANDESCENT
BULBS IN PRODUCING THE SAME AMOUNT OF LIGHT

14. THE ENERGY
CHALLENGE
VARIABLE REFRIGERANT FLOW
AIRCONDITIONING (VRF)
innovative VRF technology that enables
improved energy efficiency by allowing
occupants to choose whether to air condition or
heat only the zones in use.

15. THE ENERGY
CHALLENGE
The smart grid is a digital network that unites electrical providers, power-delivery systems and
customers, and allows two-way communication between the utility and its customers. Smart
grids have the potential to improve the efficiency of energy distribution and usage, both
through the grids’ design and through consumer participation

16. THE ENERGY
CHALLENGE
According to a ZVEI (Association of the German
Electrical Industry) study;
energy consumption for building lighting can be
reduced by up to 80 % using intelligent building
systems (KNX).
Results of this magnitude can also be achieved in
functional, as well as larger commercial buildings.

17. THE ENERGY
CHALLENGE

18. THE ENERGY
CHALLENGE
The KNX uniting all building services on a smart bus.

19. WHAT IS KNX?
KNX is the first globally standardized
system for the automation of residential
and non-residential buildings in accordance
with the following international standards :
•(ISO/IEC 14543-3),
•European standard (CENELEC EN 50090,
•CEN EN 13321-1 and 13321-2),
•Chinese standard (GB/Z 20965) and
•US standard (ANSI/ASHRAE 135).

20. WHAT IS KNX?
All components communicate via one common
language: in short, a system such as the
manufacturer and application domains
independent KNX Bus.

21. WHAT IS KNX?
This standard is based upon more than 20
years of experience in the market, amongst
others with predecessor systems to KNX: EIB,
EHS and BatiBUS

22. WHAT IS KNX?
KNX is therefore the world´s only open
Standard for the control of services in both
commercial and residential buildings.

23. WHAT IS KNX?
More than 170 internationally certified
manufacturers are members of the KNX
association.
More than 22,000 qualified KNX partners plan,
install and integrate KNX systems worldwide.

24. WHAT IS KNX?
Thousands of buildings, ranging from private
houses to airport complexes around the world,
are equipped with more than 10 million KNX
products.

25. WHAT IS KNX?
WHAT BUS TECHNOLOGIES HAVE YOU HEARD OF?

26. WHAT DOES KNX
DO?
KNX is the logical development for implementing traditional and new
requirements in electrical building installations. It thus replaces
conventional installation techniques.
Traditional installation

27. WHAT DOES KNX
DO?
The intelligent installation bus system efficiently performs the
conventional functions and offers an additional broad range
of expanded features, which could not be realized without a
bus system.
KNX Installation

28. WHAT DOES KNX
DO?
KNX interconnects all the components
in the electrical installation to form a
networked system and thus guarantees
the transparency and utilization of
information across the installation.
In this system, all users “communicate”
via a single bus cable. Thus it is possible
to integrate all the different functional
subsystems within the building into a
seamless solution.
