1. Swedark Climate Positive Elements

Swedark Climate Positive Elements Outer wall of high-performance concrete and thicker inner wall of wood is a carbon positive solution. One cubic meter of wood reduces carbon dioxide emissions by about 1.1 tons in relation to the concrete and saves 0.9 tons when concrete emits 1100 kg of carbon dioxide per cubic meter and Woods connects 900 kg. Wood insulates eight times better than a concrete that is 6 times heavier.
The Outer and inner wall is solid laminated 7 cm timber with 6cm insulation supporting structure.

Swedark Air Gap method
Resolves dampness
The method easily creates airflow through a building. There are two effects: moisture in the structure is lost, due to airflow and when dry air enters, the structure is lowered; hence the relative humidity through an interconnected array of gaps in the floor and wall columns with an air inlet and discharge. In the vertical column is warmth that causes air movement. This method helps to remedy dampness where moisture has fallen inside the vapor barrier, the plastic cover that is available in the exterior walls and roof of the building structure. (Klintberg, KTH). The heat in our method from the PCM makes the air in the gap lighter, the air rises and creates a flow of air across the gap system. A solution for the moisture robust housing in combination with a wall that is 20 cm as described above.

Swedark Air Gap PCM ventilator
Swedark has developed a new way to combine fresh air with an efficient distribution of energy in buildings. Through an effective circulation of air space surrounded by PCM increased efficiency and may reduce the need for external energy by up to 85 percent; through more resourceful use of local energy sources and more proficient air flow in the building. Distribution is fully air-based and takes place with low temperature differences with direct fresh air from the outside. PCM regulates the fresh air by adding or removing heat from the air, thus reducing the discomfort of cold air in the winter, and fresh cool air in the summer.
Swedark PCM
The National Science Federation of the United States has examined 20,000 different PCM . Melting salt hydrates and organic materials have the best potential. (Lane 1983) The PCM that today’s floor elements (Rubitherm, 2005) and wall elements (BASF, 2005) and Dupont are known. The passive PCM absorbs heat from the room. PCM is used in the cooling block, and used in trains to heat the seats in the 1800s. Based on its front-line knowledge assessment, KTH actively use PCM, which includes patent. The current research frontier is described in Chiu, Martin, Setterwall: Next Generation Cost Effective Phase Change Materials 2009.
