The temperature is rising, the days are getting longer, and it's the perfect weather to go for a swim. You can cool off and relax in the lake or the pool – but what if you're stuck working in your home office? At the height of summer, the temperatures can cause your concentration to wane. The owner of this property at Lake Constance knew about this problem all too well. His home office is located in a fully-glazed top floor room that heats up very quickly. To ensure that he could keep a cool head, he invested in an intelligent climate system: A smart weather station, heating system, solar panels and climate control system are connected to the rest of the cutting-edge technology fitted in the building. We paid a visit to the house on Lake Constance to find out how a house with large panoramic windows can automatically control its own optimum temperature.
