Energy Modeling and Computations within the construction Envelope

instills a deeper realizing of the power interactions among constructions and the surroundings, in accordance with the research of move procedures working within the construction envelope elements on the microscopic point. The author:

  • Proposes a generalized physics version that describes those interactions on the microscopic point through the macroscopic features of the construction envelope
  • Presents mathematical types that make the most of classical analytical instruments and will be used to accomplish quantitative predictions of the results of the power interactions
  • Reveals easy-to-apply engineering equipment in regards to the layout and inspection of the construction envelope, bearing in mind the results of power at the envelope

Energy Modeling and Computations within the construction Envelope offers accomplished insurance of this environmentally and economically very important subject, from the physics of strength move to its numerical estimation. The booklet is principally worthwhile to these trying to bring up development power potency, reduce the intake of basic strength companies, and lift the ecological sustainability of development products.

Pursuant to that model, if an atomic structure is isolated, the internal forces (Coulomb force RC and the centrifugal force RZ ) acting on the electrons counterbalance each other (their resultant is zero R0 = RC + RZ = 0), while the electrons run around the nucleus along particular discrete orbits and with constant kinematic characteristics. The values of the electron orbit radii rn(n = 1,2,3…) are discrete depending on the nucleus mass determining the “Z” number, that is, the sum of protons and neutrons compounding the nucleus.

A. Compton (Nobel Prize winner in physics 1927) discovered experimentally in 1923 the effect of interaction between the atomic structures and a photon flux (gamma flux). Scatter of the photon flux occurs as a result, and photon energy intensity changes together with photon wavelength (energy orbital). Reynolds (1965) registered atom transformation in 1965, proving that atoms in an excited state, even at low temperature, always pass to a more stable state by emitting one or more photons with frequency ν and energy E ph = h · ν (so-called quantum jump down).

Thus, a unified mechanism of isotropic (in all directions) distribution of photons in solids comes into being. However, the atomic structures of solids do not provide identical conditions of operation of that mechanism. 8).
