VALASSKA BYSTRICE, CZECH REPUBLIC
The object of this design is a family house in Valasska Bystrice. The project deals with the revitalization of the lighting system in the first floor of the house, which should be implemented at the same time as the overall reconstruction of the house. The proposal aims to create a healthy biodynamic lighting system that emphasizes:
1. imitation of daylight,
2. use of luminaires designed for “health and well-being”,
3. sufficient lighting intensity for individual operations,
4. use of a suitable light color (chromaticity temperature) at a suitable time,
5. energy performance of the building.

The lighting system is a full-fledged element of the smart home. It can be controlled from a smartphone, PC, or the control panel on the wall. Two types of sensors are part of a healthy biodynamic lighting system in this family house, see below. The sensors send up-to-date daylight information to the smart home control system. Based on the data from the sensors, it adjusts the intensity of the interior lighting, resp. lighting to mimic daylight and save energy:

A. Internal daylight intensity sensor – the intensity of artificial lighting is automatically adjusted according to the amount of daylight currently entering the room. When the room is very sunny, the light intensity automatically decreases, thus saving a lot of electricity.
B. Internal motion sensor – based on the data of this sensor, the lighting system switches itself on and off.
