A thinking home

Buderus heating system supplies heat as part of KNX home automation

BOSCH THERMOTECHNIK GMBH The home of Ute and Matthias Schmidt from Coburg (Germany) is unlike any other. Thanks to modern KNX standard home automation technology, their house “thinks” and acts automatically – the blinds close when they switch on the TV, the letterbox informs them when the post has been delivered and the socket with an iron plugged in switches off when nobody is in the room. This high level of comfort in the “smarthouse213” is increased even further by a Buderus heating system that is integrated into the home automation system and now also meets the design and technology standards of the house thanks to its new heat generator.

Ambient Assisted Living (AAL) with KNX

Augmented reality and voice control as most intuitive methods for HVAC interaction

BLEU COMM AZUR SARL KNX allows the control of lighting, media, shutter and shading devices especially the integration of all types of HVAC functions in the home automation environment. In the early days of KNX, some expensive and complicated software was needed to visualise the heating, cooling and electrical circuits. Today there are more intuitive ways to control the installed HVAC system. One of the most common ways is the use of smart phones and tablets.

Climate control in an aesthetically demanding penthouse

The Vitrum touch panel fulfills the high design requirements of the Milanese architect

VITRUM Functionality and design need not be in contradiction. The Italian manufacturer Vitrum has succeeded in developing HVAC solutions, which fit into aesthetically demanding environments, including all the functions of temperature management: Heating, Ventilation and Air Conditioning in home environments (HVAC).

Energy plus fresh air

Vallox – smart ventilation for optimal air balance integration

Vallox GmbH During the construction of a new residential building in Upper Bavaria, the intelligent networking of regenerative energy systems led to the building producing more energy than consumed for heating the building, heating the drinking water, ventilation technology and household usage. In addition to unconventional solutions such as a thermally active gravel trap under the house as a seasonal thermal store, the controlled ventilation with heat recovery contributes to maximising the energy efficiency and thermal comfort.

Integration of heating systems into the KNX system

The perfect integration of Vaillant heating systems into the KNX system

ISE INDIVIDUELLE SOFTWARE-ENTWICKLUNG GMBH A new building near Dortmund, the house owner has fulfilled his dream of an intelligent house tailored to him and furnishes his home with KNX. To further increase energy efficiency, the heating system was also integrated into the KNX system. Thus, e.g. now also the heating system can switch to "standby mode". As a result, (if desired) the setpoint values for the room temperature are declined in all rooms and the heating capacity is reduced.


Solution 1

KNX as a subsystem for price-sensitive solutions

KNX offers interesting solutions as a dedicated climate control system

ARCUS-EDS GMBH Due to KFW funding according to KFW70, ventilation with heat recovery was necessary in order to meet the KFW70 energy standard. The good thermal insulation and the air-tight outer shell of the building also incurred the risk of damage due to damp. The ventilation should therefore also be controlled by moisture and the room temperature in each room controlled separately. In this case, a conventional installation had no advantages compared to a KNX solution.

New smart buildings on French production site

Integration of SAUTER BACnet / IP-KNX controllers and HAGER KNX devices

FR. SAUTER AG A specialist in electrical installation since 1955, Hager Group nowadays is a worldwide leading supplier of solutions and services for electrical installations in residential, commercial and industrial buildings. Hager Group is present with 28 production sites around the globe, and customers in more than 120 countries. The largest industrial site in the group – situated in Obernai (France) – is constantly on course for expansion. Since last year the new Hager FORUM provides a 6,500 m² open, collaborative space, where visitors can meet and exchange with Hager Group.

Office building with high level of comfort and energy savings

Control signal for fan coils offers efficient control and noiseless fan operation

EKINEX Fan coil units are a very common and successful solution for room heating and cooling in functional buildings. In order to save energy and reduce the noise at workplaces, there is a growing demand for units equipped with brushless electronic motors and inverter boards. These types of devices need to be controlled by actuators which generate a 0 – 10 V control signal in order to allow a continuous air flow. In this project, KNX was chosen for its native interoperability and the availability of a new ekinex® solution for the 0 – 10 V control of fan coil units which made the integration of heating, cooling and ventilation in the building automation’s overall concept much easier.

Only as much as necessary, not as much as possible

DCV solution for demand-based ventilation

BELIMO AUTOMATION AG The DCV technology (Demand Controlled Ventilation) measures the conditions in a room and calculates the amount of air actually required. It is applied to regulate the fans according to the demand. Devices used are sensors and control devices for CO 2 , VOC, temperature and so on. The required air volume is supplied to the room by precise volumetric flow controllers.

Optimal air quality in rooms with lots of people

More energy efficiency through KNX room temperature controller with CO2 sensor

BUSCH-JAEGER ELEKTRO GMBH An ideal KNX room temperature controller not only measures the temperature but also the air humidity, the carbon dioxide concentrations in the air and the air pressure. The CO 2 concentration depends on the air pressure, which in turn is determined by varying weather conditions (low and high pressure), changes in the altitude of the measuring location (meters above sea level), and also air flows. It is therefore important that the air pressure be taken into account when measuring concentrations of carbon dioxide in the air.
