Energy efficiency at dome-house
This article refers to the technical efficiency of a dome home, and about how to build energy-efficient housing 21 and that this is necessary.
The main factor affecting the efficient use of materials and energy efficiency design - a form. The sphere has the smallest ratio of the area of ​​external walls to the internal volume of the building all the pieces of the same capacity. The smaller the total area of ​​the walls and roof, the higher the efficiency of energy consumption for climate control in the room. Dome houses the most attractive and cost-effective, in combination with modern materials and the correct design costs for heating (and cooling), they are less by 70-90%. This geometry is in the service of the dome.

The surface of the ball about a quarter less than the surface area of ​​a cube of the same volume, and hence the materials for the construction of the dome will need a quarter less. In addition, the dome, 60-70% fewer parts in the frame design, saving an additional 5-10% of energy in the absence of "cold bridges" because of the homogeneity of the material of guards and still save 40% of the time to build. This technology in the service of the dome.

The positive ratio of area to volume gives an amazing thermal characteristic domes. The surface area exposed to the environment has far more influence on the energy efficiency of the house, than the quality of putty in the seams, and the thickness of its walls, and the heat loss does not depend on the basement floor area, and the length of the perimeter. These are the laws of physics in the service of the dome.

Heat loss of the building is in direct proportion to its drag. Wind glides over and around the dome, creating insufficient twists and funnel to disrupt the boundary layer of air, which is attached to the surface of any object intermolecular microgravity. Thanks to the aerodynamic effect of the wind goes around the dome design with lower resistance.
The curved surface of the inside of the dome facilitates natural air circulation and effective air exchange in the room. Natural "annular" flow of air to prevent stratification and the temperature remains the same throughout the volume of the dome, from the floor to the apex. Aerodynamic effect design saves a lot of money on heating and air-conditioning.

The rectangular building is very high windage. Wind hits right in the vertical wall, breaks a heat insulating layer of air creates a high pressure area. A leeward side of the building at the time under the influence of turbulent flows and the partial vacuum.

Twist cool the building, and the vacuum sucks the hot air out of the room, not only through the cracks around doors and windows, but any tiny imperfections in the design of the building. Warm air is sucked out of the room, replaced by a cold, downwind, through these cracks, microcracks and micropores. Even in modern homes total area of ​​cracks and pores are the equivalent of an open window. Expanding in a dense area, the cold air is further cooled by the effect Bernouli and turns into a draft, drawn by suction. The design of the dome lacks such drafts.

The positive ratio of area to volume - not the only reason for the amazing thermal performance domes smaller percentage enclosed air in contact with the shell, where there is loss of thermal energy, or unwanted heating. Doubling the size of the dome leads to doubling his thermal efficiency. These are laws of aerodynamics and thermodynamics in the service of the dome.
