The building has a southern-facing aspect with a lot of window surfaces to ensure the environmental atmosphere and the solar yield in winter. The properly constructed building structures ensure the shading during the summer. The ventilation system, completed with ground colletor provides the fresh air.
As the building will be my home, during planning period we have been taking my family’s needs into consideration. We also ignored all aspects, which are essential when building a passive- house.
Most of the people are aware of the importance of environmental protection and that building energy-saving houses (in large numbers) has a primarily importance with respect to our planet. Unfortunately, building such houses nowadays means significant financial investment surplus costs in the hope of subsequently energy (financial) savings. This extra cost is the only obstacle of spreading passive and active houses in large numbers.
