We do perform building physical calculations for heat, moisture, sound and fire insulation of structural components or complete building projects. All the analysis are in according with the current European (and German) standards and the latest informations about the products of the building material industry.

• calculation of transmission heat losses using Fx-values, integration of thermal bridges, losses to the ground (including stationary or harmonious conductance), front buildings of glass
• explicite calculation of thermal bridges
• energy losses of integrated heating surfaces
• internal heat gains
• solar heat gains of windows, winter gardens, opaque structural units transparent heat insulation, radiation intensities and shading factors
• determination of the effective heat storage capacity
• calculation of heat and warm water requirements
• calculation of primary energy requirements and transmission energy losses, limiting values according to German EnEV 2001 / 2002
• graphical preparation: monthly or periodical balances, energy profiles
• comparison of two building and calculation varieties

• room acoustics, calculation of reverberation times
• protection against airborne and footfall sound transmission from other´s living and working areas, DIN 4109, solid construction, wood and other skeleton building methods
• consideration for influence of flanking construction elements
• protection against external noise, resulting sound reduction indices
• goesele procedure for timber beam floors
• sound control stages according to VDI recommendation 4100
• calculation of noise level ranges according to DIN 18005, road and train services, parking lots, navigation, line and area sound sources, partial sound sources
• determination of building sound reduction indices according to EN ISO 717-1
• wall development with absorption coefficients for the determination of the reverberation time • footfall sound protection according to DIN EN 12354-2
