092 - The Nest
The Nest combines a minimalistic design with ecological building materials considering a sophisticated energy-efficent logic.
The room arrangement is designed in order to permit a good view on the wood stove from any angle of the object's interior increasing the resident's confort and at the same time illuminates the whole space. A panorama window is the direct interface to nature. During warmer seasons it can be widely opened.
The bed easily offers enough space for a maximum of two adults and is completely accessible from the living room. It is possible to furnish the cabin's interior in a completely personalized way, e.g. setting up a work desk or dining table. The entrance area accommodates a wardrobe with storage space and the technical room.
A simple timber construction generates the base frame for the block-shaped body. This enables us to use less single elements minimizing construction complexity and guarantees reproducibility. The planking is made of weatherproof wooden laths in a vertical arrangement.
All inside walls are made of homogeneous plywood. The flat-roof is closed with a rubber sealing protecting the building from humidity. In order to provide the wood stove with firewood there is a wheeled box for it under the bed. Filling it with firewood can be done by simply pulling it out from the outside of the cabin. For taking firewood from the cabin's inside the box can also slide from beneath the bed into the other direction.
The panorama window mentioned earlier maximizes the natural use of daylight to the best degree. As required, it enables the resident to dim light of the living space using wooden shutters. To permit lighting by night there are energy-efficient LED-lights.
4. Energy Concept
The insulation of the walls is made from hemp which is an extra ecofriendly material due to its good climate balance. Green-roofing made from moss increases insulation on top of that.
A double-door-system prevents uncontrolled air exchange between in the object's inside and outside. The wood stove delivers direct heat and is equipped with a heat
exchanger. If there is a fire burning in stove water is permanently being heated up. A hot water circuit delivers energy to a thermal storage system. A second heat exchanger is connected to a ventilation system in order to preheat fresh air from the outside. This way smooth and adjustable heating is possible. The room stays warm even after the fire goes out. To provide elecricity for lighting, and the fan a photovoltaic system is necessary. Because of the cabins location there might be not enough sunlight during the day to provide enough solar energy. In that case the PV-panel must be placed on top of a tree or outside the forest.
Measures to improve sustainability:
- Wood stove incl. heat exchanger and thermal storage system - Cork carpet
- Hemp insulation
- Green-roofing using local moss species
- Ecofriendly wood treatment
