When constructing glass houses, we need to pay attention not only to excellent results from energy indicators, but, in particular, to the client, who is building his home. The sustainability principle, which is fully summarized in the design and implementation of houses, is one of the most important factors. The house should be seen throughout its durability cycle, taking into account the longevity of embedded components, the needs of residents in different life periods, the living costs and, of course, the psychological function of the building. Contact with nature Vita Nova is inextricably linked with nature, because its basic and primary structure is made of wood. The wood that is built into Vita Nova is of the highest quality. Contact with nature is not only provided by natural materials that surround us, but also by transparent glass surfaces, that allow us to experience the surroundings every hour of the day, at any season and in any weather. Through the large glass surfaces we can see the first sun rays of the day and from the shelter of the living room we can observe last ones of a cold autumn evening. With a book in our hands, looking in the distance, we can listen to the raindrops, which forecast the far-away storm. Sitting beside a fire from a fireplace we can watch the arrival of the winter days, announced by the first snowflakes. Life in Vita Nova does not only represent a superior living comfort, rather it is a first-hand experience of our environment. Natural light is one of the essential factors that affect it. In the morning, light is different than at noon or in the evening. In New York it is different than in Barcelona or Paris. All of this affects our physiological processes in the body and our soul. If you enter a dark room, you can get in a bad mood. However, if you come to a bright place, you can improve your well-being.
