In January 1984, America's united technology company builted the first intelligent building construction,  it was locatedin Hartford ciity, Connecticut sate, which was  intelligently renovated by an old financial building, and realized the computer control of the building air conditioning, power, water supply, security, fire prevention system and so on, improved the efficiency and the security of the building[3].
Japan began to build the intelligent building in 1985, assigned the development plans, from intelligent equipment, intelligent family to intelligent building and city, etc., and also established the "JIBI" and "Professional Committee of Intelligent Buildings for National Construction"[4].

SORPAS is a simulation software used by professional engineers (specialists in welding) in industry (including automobile manufacturing, welded, welding equipment, electronics and other metalworking industries) to determine and evaluate combinations of materials in regarding the weldability and the design and selection of electrodes and general optimization of welding process parameters [1].

At the same time, atmospheric transmittance of infrared radiation is an important parameter which measures the atmospheric transmission attenuation effect of infrared radiation, and it has important impact on the design, performance and evaluation of infrared system, e.g. tracking system, searching system, warning system and thermography system et al. [1] Now, there are two kinds of commonly used methods for calculating atmospheric transmittance [2]: one is the method of exact calculation using the professional atmospheric analysis and calculation softwares, such as Modtran and Lowtran; the other one is approximate calculation using theoretical approaches and empirical formula (algorithm of empirical formula).
Atmospheric attenuation mainly includes [7]: 1) absorption attenuation caused by molecules in the atmosphere (mainly including water vapor and carbon dioxide); 2) scattering attenuation by aerosol particles in the air; 3) particular weather conditions (such as snow, rain and fog et al.).
Therefor the total atmospheric transmittance can be calculated by the following formula: (1) Wherein tH2O(we) and tCO2(Re) are atmospheric transmittance arising from absorption attenuation respectively caused by water vapor and carbon dioxide respectively, tH2O(we) can be obtained by looking up the table (spectral transmittance of water vapor at horizontal path above sea-level) with we converting from precipitable water w; tCO2(Re) can also be obtained by looking up the table(spectral transmittance of carbon dioxide at horizontal path above sea-level) with Re converting from the R which is horizontal distance; And DV is atmospheric visibility, Jrain is rainfall intensity, Jsnow is snowfall intensity, wl is wavelength.
Steps of calculating atmospheric transmittance arising from absorption due to water vapor (H2O): 1) Firstly, in order to obtain w0 (condensable vapors per kilometer in 100% relative humidity), looking up the corresponding table with atmospheric temperature T. 2) Then calculating the precipitable water w which equals to the product of distance R, relative humidity Hr and w0. 3) Performing the correction of precipitable water, i.e. converting w into the equivalent precipitable water we in the surface layer. 4) Finally, looking up the corresponding table for tH2O with the parameters including wavelength wl and precipitable water we.
System functions shown in the GUI mainly include: calculating atmospheric transmittance with the appointed wavelength, plotting atmospheric transmittance of water vapor and carbon dioxide curves, drawing simulated images in the infrared band and calculating atmospheric transmittance of infrared radiation with rainfall or snowfall intensity in particular weather condition.
