great effort, we realize complex home automation systems. Technology is in vogue! We believe in quality of life and ease our conscience towards the environment. The temptation is great, one can hardly resist her: Automation! The systems will, without our intervention, to adapt to our behavior. We are free! But if you look closely, we create another "technical" state of which we depend.
The systems are complex, it requires an increased control effort. Technically, today control almost any wish can be fulfilled. From simple circuits to computer-driven programs with the involvement of several parameters. But which control for whom? Maybe that would have the pleasure of a fully automated computer system - the majority of people that could hardly do something.
following situation we have discussed recently in the office in a small schoolhouse with four class units for mentally disabled young people, are controlled for ventilation and night cooling in summer motorized window sash. In a bigger school you control such a system usually centrally via a networked computer with the system supplier. For a small school building such a system is too expensive and too complex to operate.
For our small school therefore a significant one for economic reasons is already clear. The system must be via electronic switches (bus system) is controlled. To meet the requirements, parameters must be set with priorities be. These parameters arise from the energy requirements (heat loss), weather-related requirements (rain, storm) and the user-specific needs (teachers, students), the latter occupies a special position because it engages in the direct daily life.
in dealings with the user-specific needs, two opposite attitudes. One possibility would be to install in any room Co2 sensors that trigger after a certain amount of CO2 in the air, a shock ventilation. For the indoor air quality that is certainly the best solution, but one which time uncoordinated Open middle of the class has a disturbing, perceptive sensitive especially for young people. Another possibility is the time-coordinated air, triggering the opening of the wings at the end of the lesson. The result is a rhythm, similar to the break ring. The sudden opening of the air wing become such a taken for granted in everyday life.
If we set this requirement as the basic parameters provides our switching system as follows:
basic parameters: coordination, periodic timer to blow air through school hours based.
side parameters I: technical improvements to the energy (heat loss in winter) will prevent airing in unoccupied rooms by Co2 sensor.
side parameters II: night cooling controlled with appropriate outdoor temperature control with outside temperature sensor and timer.
side parameters III: End of the night cooling as it reaches a certain internal temperature using internal temperature sensor or in bad weather and weather station.
I think we were able to achieve the needs of such control, which stops a day to understand the logic.
The control and operation of the home technology requires extremely careful planning. For it is precisely the operation of these things that unconsciously every day strong, usually intervenes in the lives of the residents. Above all, we (future) Architects are required in this topic. Only we know the needs of the client in such an extent that it requires the development of such controls. The conscious use of the control we need to learn.
