2. Smart Cities Concept The Energy Challenge KNX and its features 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 footprintall 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 worlds 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. KNX installation at Shanghai Hongqiao Airport 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. 29. WHAT DOES KNX DO? APPLICATION S Lighting HVAC Shutter Control Security Energy management Automation Communication Busch Comfort touch panel 30. KNX SYSTEM INTEGRATION KNX Installation PLANNING AND CONCEPTUALISATION: Working with consultants and client in order to fully understand the concept. ENGINEERING: The system devices required for implementing the KNX network are defined. The project engineering using the ETS on the basis of the functional description also takes place in this phase. COMMISSIONING: During the commissioning phase, the KNX devices are installed and programmed. HANDOVER: The programmed functions are checked for compliance to the requirements in the functional description. DOCUMENTATION: The customer receives the project documentation (schematics, function description and ETS project data) 31. THE KNX ADVANTAGE A single multi-function switch with the following capability. Light ON/OFF Dimming control AC control Shutter control Event display Scenes Distributed Audio control 32. Private houses / flats / apartments e.g. ShiMao SheShan Villa, China Hotels / restaurants e.g. Four Seasons, Egypt Schools / universities e.g. Grammar School Neufahrn, Germany Stadiums e.g. Sazka Stadium, Czech Republic Hospitals / care homes e.g. Triemli Spital, Switzerland Industrial / production buildings e.g. Airbus production, Germany Airports / railway stations e.g. Thessaloniki Airport, Greece THE KNX ADVANTAGE 33. THE KNX ADVANTAGE ABB i-bus KNX automation technology provides energy efficiency, comfort and safety in each of the 499 guest rooms of the innovative Yas Marina hotel in Abu Dhabi. ABB i-bus KNX system increases energy efficiency in the CIRCA on Jellicoe art gallery in Johannesburg, by controlling multiple types of lights and using motion detection sensors. ABB i-bus KNX intelligent control system installed in the Ministry of Higher Education's head office in Riyadh, Saudi Arabia, enabling energy efficiency saving of 35 percent 34. The heart of any building is its electrical installation which enables the building with power for Lighting, cooling , communications and other building services. As Engineers our mandate is to continually find ways to deliver value to our clients while taking into consideration the long term benefits to the society. THE KNX OPPORTUNITY 35.
