 So, sighting, looking for a good space, and here we of course have very different climates. The situation is very different in different parts of a country. Altitude plays a major role. So a house that is higher up into the hills and mountains will have more cold weather, maybe more wind exposure, and so on, and so if you are in a wind shaded area, you may have a lot less energy demand in cold climates, but it may be good to be exposed to wind in a warm climate to have more comfortable temperature in the house. And of course, excess is absolutely important. There is a tendency that eco houses are built in beautiful areas, a little bit far out of the city sometimes somehow. And is that an eco house? If the house is made with eco-friendly materials, everything wonderful, but then the inhabitants, they commute like 100 kilometers each day, and well, that would destroy everything that you make eco in the house, and that's sort of creating a lot of energy demand over a very long time span.
