Today's climate change challenges require architects to focus on creating a regenerative architecture that creates a habitat with natural materials that have a positive effect on the conservation of the natural environment. Designing a small object like this could not cover all the guiding principles in creating such an architecture but could show the application of one of them. It is desirable to seek the creation of a regionally specific architecture, in such cases that uses local natural resources as building material. Regenerative architecture is distinct from the traditional one in that it recreates much of the natural resource used. This is especially true of the different tree species that adsorb carbon dioxide during their growth and subsequently become a future building material. We must try to minimize the use of existing resources and strive to close the cycle between what we use and what we create.
The proposed design solution is from building materials for which no energy is consumed from non-renewable energy resource and insulation, which is from waste wood sawdust. This type of insulation is used in Alpine shelter at altitudes above 3000 m. The thickness of the insulation is 20 cm and in the application it is more than 3000 m from 25 cm. The outer cover of the shelter is wooden, 25 mm thick, and burned with a gas lamp up to 3 mm from the thickness of the surface layer. This is in old Japanese method to prevent the tree from rotting. For the foundations of the building, the rest of the stone blocks from the destroyed shelter and other suitable from the site will be used. The wooden farms of the roof structure will be prepared in industrial conditions with the possibility of transporting them in dismantled form to the construction site. The thermal insulation "Pavaterm" (made of wooden fillings) will be placed in plywood panels with a light weight of about 15 kg. And with the possibility of delivery on site and by hand. A multilayer layer of birch bark will be laid on the roof panels, with a 15 cm soil layer for the construction of the green roof. This type of roofing is traditional for the Scandinavian countries. If it is properly laid, its durability is 80 years. The interior of the shelter will be covered with plywood, painted with one hand water-based paint. The furniture is made of two tables and two benches, offering 8-10 places for dining, 6 places for overnight stay with 6 unfolding pines. With two extra seats on both tables. The windows are made of three-layer joinery / Ideal Combi Futura / The glazing will be protected with wooden shutters. The stone wall in front of the front door is to prevent snow accumulation in the storm. The cantilever extension above the stone walls is to create niches for overnight stays that extend with folding pomegranates. During the day, pomegranates reduce the heated volume of the building and serve as cabinets for the storage of blankets and mattresses. From the outside, under the deep eaves, wood can be stored in the back, and in the front there are outdoor resting areas. A fireplace with wood will be used for heating. El. The power supply is a combined system consisting of a small wind turbine and a solar photovoltaic panel, providing power for lighting and using electronic devices. The shelter equipment also includes a signal amplifier from mobile operators. To this project we propose to plant 1,000 birch trees that will provide new material resources for future eco initiatives in 35 years. During this period the trees will adsorb 1250 tons of carbon dioxide. For the construction of the shelter will be used 140 m / to make the farms, 60 m2 insulation, 80 m2 birch plywood and 22 m2 boards. To these basic materials and electric energy equipment, electronic equipment, fireplace, windows and doors total BGN 14,000. Additional unrecorded costs, including labor, amount to BGN 11,000. Total value of BGN 25,000
