Planning‍‍‍ a new residential premises with KNX Home Automation?
Sarlux Electronics offers expert guidance on how to go about choosing KNX technology for your new home.
If you are going to build your home from scratch, it is an ideal time to think ahead about the smart home automation system. Besides having a gorgeous décor, the new generation of homeowners wants features like smart lighting, climate control, energy efficiency, better security, ease of use. KNX provides an integrated smart home solution which can combine all these facilities on the same platform through a single controller panel.
To design your home/ house/villa/luxury residence/ apartment with KNX based smart solutions here in India is a great way for the home owner to get a connected living environment. This can be achieved by a smart control system based on KNX technology, which will allow devices such as a lighting, curtain control, central heating unit (HVAC system) etc. from a variety of manufacturers (which are compatible with KNX protocol) to be operated through an automation control system which would function as both the control panel and the database.
Sarlux Electronics helps home owners, architects, interior designers, and electricians in India by offering professional consultancy on smart lighting and control systems solutions for new and already existing houses/ houses/ flats. It is wise to have a basic understanding of KNX technology before the actual physical construction work starts. The more knowledgeable you are, the more informed would be your decisions regarding electric wiring and automation features.
Long-Term‍‍‍ Maintainability
Documentation is key to making an installed KNX system maintainable and expandable. In fact, it will help the service to come when you get a new installer to see which devices and programming will suit you best after some change to your needs.
Future growth is dependent and to some degree limited by the original electrical installations, actuator capacities, system design, device compatibility, and space availability.
Centralised Control
KNX can bring all lighting, blinds, and climate functions together without needing unrelated controls.
Local wall controls remain a very nice option even after the installation through touch panels or compatible interfaces which allow the use to the operation via multiple places of the building.
Potential Energy Savings
A KNX system that integrates occupancy sensors, daylight-adaptable lighting, schedules, and climate control strategies that are best for the home can lead to savings on energy bills for a house that makes the best use of these.
Savings are highly determined by the way that people use and set up their systems. Automated systems do not lower the electrical bill per se they save money only when the settings, equipment, or the household use are not a waste of ‍‍‍resources.
KNX Home Automation: A Definition
KNX is, indeed, the global standard for smart home technology. The system connects multiple appliances made by various companies through a single platform to let you manipulate the entire building’s operations, including lighting, shading, heating and cooling, and of course some security functions, just to name a few.
A typical situation is where you would want your wall-mounted switches, your mobile apps, your touch panels, your sensors as well as your automatically activated scenes to all be linked together and used via a single KNX system.
In the case of a front door, for instance, a single button could be the controller for your chosen lights, the opening of blinds, and the adjustment of your air conditioning system’s settings to a minimum amount of energy used, etc. These steps of execution of commands can be altered according to how the person lives in his house so that his daily chores can be handled with the help of the system.
With this kind of system you can be at ease with the knowledge that you have an intelligent house yet without the need of having to keep your mobile phone as the only method of control of all the lighting, air conditioning and other systems in the house.
KNX Technology: The Secret of a Smart ‍‍‍House
KNX‍‍‍ turns your flat into a smart home by linking up sensors, switches, actuators and controllers. Once connected they can respond to user commands and follow programmed conditions.
Below is a list of how exactly this technology helps in daily living scenarios.
1. Intelligent Lighting Control
Lighting is among the prime benefits of home automation via KNX. Instead of flipping the light switch individually for each light, one can create groups of lights by room, floor or even activity!
For instance, the TV area may be different from the one when people come over or when it’s time to have a drink and read a bit. All with the press of a button, the right scene will set the lighting level and switch lights on and off at the same time.
An intelligent illumination system through KNX is able to offer such possibilities:
Light switching of single lamps or grouped ones.
Dimming for suitable light systems.
Corridors or specific areas where lighting is activated via motion detection.
Daylight responsive lighting at locations with sensors and controls.
Selected rooms to have scheduled lighting.
Ceiling lights control with different scenes.

If you are building from scratch then it must be done at the same time as the power and building layout plan for interior works and lighting.
2. Remote Control of Window Curtains and Blinds
If you use motorised blinds and curtains then you might decide to add KNX to the set-up. It makes window coverings remotely可控 using, e.g., wall-mounted switches, touch panels or automation interfaces (depending on the supported features).
A scene can be programmed: it opens the windows in morning, closes the blinds when the sun is too bright or lowers the windows for a movie night.
Blinds with sensor input and logic can even support solar heat control. How efficient the energy saving feature really is depends on the type of glazing, house orientation, local climate and general design features.
For houses, villas, and large apartments that have several rooms, synchronized curtain automation is a big convenience factor.
3. Smart Air Conditioning and Climate Control
Komfortable room temperatures and a good indoor climate can be maintained via KNX that integrates suitable hvac equipment and room ‍‍‍controllers.
Imagine‍‍‍ that you can have separate temperature controls for each room that are adjusted to the occupancy of that room and the preference of family members. This is not only a system with a temperature setting, but it can also adjust the desired climate conditions that your home is in to match the different scenes of your house, e.g. when you are at home, when you are leaving, in bed, etc.
Benefits can, for example, be a room-to-room temperature adjustment that is possible in certain setups. Heating or cooling of your home can be scheduled through automatic switches.

Other Potential AdvantagesConnecting with compatible thermostats and HVAC interfaces.Preventing unnecessary operation through good logic automation.Control between climate, occupancy, and other functions.
Compatibility is important. It is not guaranteed that all air conditioning units can be connected directly to KNX system, therefore, you should check whether a gateway, interface, or controller is necessary in your case.
A.4 Smart Security And Entry Control
To a certain extent, KNX and sensors and systems that are connected can make a more secure and comfortable home by using security functions as well as entry control. In addition to that, they can also control lighting as per your liking.
Depending on the system design, KNX might allow linking with a burglar alarm or monitoring through an appropriate interface.
Nevertheless, KNX integration should not automatically mean that a dedicated security system is being replaced or supplemented. For intruder alarms, CCTV cameras, fire detectors, and emergency systems, the equipment needed and their configuration are quite specific. They generally are not suitable for DIY installation, but require professional services.
A. Why Should You Consider KNX for a New Home?
It can be easier to plan a KNX installation during the construction phase of the house. It is more complicated to retrofit a finished property that is fully built and equipped.
A.1 Better Electrical Planning
Your architect, electrical engineer, and automaker can decide on where your lights are going, switches, where you’ll control the home with panels and how the house’s systems communicate.
That way, you save on time and money for any changes later on.

A.2 Flexible System Design
KNX allows the manufacturers to use their products, even from different suppliers that still conform withKNX requirements which in turn offers you greater choice in switches, sensors, actuators and control interfaces. On this subject, of course, the compatibility between products, the functionality of the features still needs to be assessed for the given installation, ‍‍‍etc.

What‍‍‍ Is the Cost of aKNX Home Automation System in India?
A KNX smart home system price can never be a universal figure, as your final budget entirely rests upon various factors. You can’t just take away the price of KNX because the factors influencing your final price may vary significantly from one person to another. If you have an open-space design then you definitely need the right number of controllers to handle a great number of electrical circuits. For example if you want your HVAC system to automatically turn on or off depending on the room temperature you will need different KNX products to communicate with each other. Similarly curtain motors, keypads with various styles, sensors of all types, touch panels, etc. will all be considered while calculating the overall price. Installation complexity will play a huge role too.
Largely, the project cost hinges on;
Property size: A bigger house might require several KNX components and additional circuits.
Level of lighting control: Simply turning lights on/off might be an inexpensive option compared to having a room where lights can be set to different levels or scenes through a remote control.
Controlling windows: Every motorizedis a new component that also requires its integration which adds to the overall hardware and installation expense.

In order to get a precise estimate of the cost your KNX contractor should produce a schedule, per room, where the main elements of the system are identified and their costs broken down including that of hardware, labour, programming, commissioning, and optional accessories.
It is a bad idea to compare quotes based on the total price only.
Check which functions are included, make models, the guarantee (warranty?), the supporting document and what after-sales service is ‍‍‍provided.
How‍‍‍ To Plan KNX Automation Before You Build Your House
In order to have a perfect installation you’ll first think about the things you do daily rather than compiling a long list of devices you want.
Step 1: List your needs
It’s a good idea to plan automation so that the rooms in the house that you will be having the most time at will be equipped with automated systems for lights, motorised blinds, thermostats etc. This could be the bedroom where you sleep most of the time or the living room where you hang out after a long day at work. It’s also a good idea to plan for the integration with the whole security system. Scenes could be another nice feature if you want to control all lighting in one click for example.
Of course, you can choose to have all these features in all the rooms but if you’re on a budget then you may decide to have them only in certain rooms.
Step 2: Coordinate electric installation with the design team
It’s important that you show them your home automation ideas when you are working with the architect, interior designer, electricians, and other experts before you decide on the type of light fittings and the ceiling layout. Because your design choices will influence how your wires run.
Step 3: Choose KNX equipments that will be compatible
Ask if they need a specific type of switchboard, motor control, movement sensors, or any other devices. Make sure that they can use them with light fixtures and HVAC (heating, ventilation, and air conditioning) units.
Step 4: Run through a test, check it out and get a documentation
A professional will be the one who should carry out the testing of each programmed scene and control function to make sure that you’re not going to be stuck at some point without knowing exactly why something stops working as it should. You should make sure that there is everything needed for your reference such as updated drawings, device lists, program description, and handover instructions.
This method of going about it helps to steer clear of one major mistake the decision of buying pretty-looking smart switches first and later realising that the electrical installation or equipment connected cannot support the features you wanted.
What KNX Capabilities are Available in Residential Applications like an Apartment?, a Villa?, or even a Luxury Home?
KNX could very well match the type of home you are planning provided the system is tailored to meet your particular project needs.
Apart from an apartment, for example, it only takes a few light scenes, curtain and climate control functions without the whole automation of electricity functions.
An independent house can make full use of automated lighting, thermostats and motorised blinds on various flooring, and room arrangements with coordinated control.
A large villa with a lot of outdoor lighting, HVAC units with different zones, landscape and motorised blinds covering almost all windows may require a very complex system design.
KNX may still be considered for an old property, although the contractor’s report will include a technical audit of the existing installations and whether a wireless option is feasible.
If it’s a new construction, the most vital thing is to get advice from an automation expert right from the start to get a full picture of what the system needs and how it will be set up to co-ordinate with the building ‍‍‍itself.
