„Building management systems today may provide the most positive added value in the areas of ventilation and cooling”

Not only can a smart home simplify its residents’ everyday lives through automation, but certain solutions may even reduce the impact of the property on the environment, and can provide many security and safety features. In our series, you will learn about the world of smart homes. Our goal is to provide the appropriate knowledge for decision-making and for starting to design a house.

In a smart home, there are many things that can be automated and digitally designed around us that make our lives easier on a daily basis, whether it be lighting, shading or temperature control, or access control. These building management systems are designed to best suit today’s modern household needs also in terms of engineering, building maintenance, ventilation, cooling and heating. “When looking at smart homes from the perspective of windows and doors, the average person first thinks that doors, windows and shades may be somehow operated by motor. However, compared to this, the spectrum is a lot wider and individual versions can be mixed,” says Károly Lovász, Managing Director of KAV. Then he outlines in detail what variants might exist. “If the operation of windows and doors is integrated into a building management system, it offers many unique solutions. Some only test the condition of the product. The burglar sensor, opening feature, that is, for example, if a manually operated window is open, it knows that the ventilation needs to be turned off in the room. But there are many motorizing and automation options that may be adapted to the everyday life and habits of residents. The windows could be tilted at an angle if I walk in front of them, or if I use the restroom, switching on the light lets it know that the window must be opened and then closed back with a delay of five to ten minutes. Starting with these functions, you can reach as far as logging and examining fingerprint access at front doors, then customizing lighting arrangements according to the taste of the family member who’s arrived, turning on a music player, or activating other voice-controlled gadgets in your room that were switched off until then. If the residents are not at home, the system can mimic the family members’ habits based on the data stored; turn on the lights, release the blinds and open the windows as they do in their daily lives. This ensures that the use is visible from the outside so that burglars avoid the property. ”

However, building management systems can provide the most positive added value in the areas of ventilation and cooling. They combine the movement of windows and shutters with a variety of mechanical tools to minimize the use of and investment in energy. For example, in the spring, when it senses that the outside is slightly cooler than the indoor temperature, the system will open the windows slightly and calibrate a fine draft according to the wind direction. As it ventilates the house, it also takes care of shading, because it knows that when it is sunny, it will result in a serious heat build-up behind the large glass surface. But there are also systems that monitor cooling and heating. Let’s say the system may be programmed to receive permission to pull up blinds and let in sunlight in communal areas – living-dining room, kitchen, conservatory – in cooler times, constantly increasing the temperature in these spaces. When, for example, temperatures rises above 26 degrees in a given space (or it sees a prediction in the weather forecast), it suddenly sucks this hot air out of that space, and the multi-channel mechanical ventilation system delivers it to other interior or shaded areas. This way, through heat control, it sets the optimum temperature everywhere in an environmentally friendly way. In warmer periods, this process can also be programmed in reverse: if the system senses too much heat, it shuts the doors, lowers the shading, adjusts the amount of directed light entering the interior to achieve 100% effective shading and, if necessary, turns on the air conditioning. Not only do these solutions make life easier for residents, but they also minimize the impact of the property on the environment.

Aluminium doors and windows with custom solutions
The founding of KAV Hungária was also triggered by an innovative idea: why not introduce aluminium doors and windows to the family home market? Since then, our own developments, individual solutions, needs assessment and construction work organisation have become the defining elements of the company. Károly Lovász, the managing director of KAV, Gábor Csóti, the founder of the Gamechangers community and Kálmán Szabó, the host of the podcast by the Association for Excellence Public Benefit Association, spoke about innovation, the underlying managerial thinking and organisational structure.

Why is it worth choosing an aluminium front door?
When building or renovating a house, developers and architects may be wondering when it is worth deciding on an aluminium front door. In addition to durability, the main argument may be that aluminium can deliver dimensions and solutions that neither wood nor plastics allow.

We build for the future rather than for today
Clear shapes, large glass surfaces, spacious interior spaces and creative use of materials – these are the main features of the most predominant architectural style of our era, minimalistic design, in which interest is outstanding in Hungary. However, the number of really well designed and built minimalistic family homes is relatively low. The property our engineers consider as one of the best designed ones our company has met in recent years was built in Budapest. During the project we paid increased attention to the design of large, liberally designed glass surfaces, essential for creating open spaces. We had a conversation with the developer of the house about what was needed to create this property.

The evolution of closing systems in Hungary
If one spends many years in a specialised technical segment, sometimes answering questions from a professional interviewer will inadvertently recall the period from the beginning to the present. Studying the evolution of window and door products used in residential buildings is also instructive, because fashion always changes along with demand and financial opportunities. Everyone sees the past differently - we, Hungarians are special in this - but sales figures outweigh perceptions.

Ethical operations raise even SMEs to the top
Following the large enterprise sector, operating ethically is becoming increasingly important for small and medium-sized enterprises, too. These companies not only take into account the interests of their clients and suppliers but also those of their environment and employees. They set an example by their activity and attitude and strengthen trust. This attitude may constitute a basis for long-term operation and economic stability, and what is more, employees of the Y and Z generations are more eager to opt for an ethically operating workplace.

A refined aesthetic for doors and windows
The popularity of the minimalist style in architecture is one of the reasons that aluminium doors and windows entered the family house sector. Applying the principle of “less is more” to architecture led architects and designers to use unique solutions and austere or transparent surfaces. In a minimalist home, simple shapes and forms help create an atmosphere of harmony, where space itself serves humanity.
