THERMAL ANALYSIS 1D

THERMAL ANALYSIS 1D is a program for the calculation and assessment of the building components in terms of heat and vapor transfer. The program includes various calculation assistants to take into account the systematic thermal bridges, the influence of the connections on the diffusion resistance factor of the material and others. Catalogues of materials, structures and boundary conditions are available. Using the program, you can create:

  • Complex hygrothermal examination of the structures or windows according to ČSN 73 0540-2 or STN 73 0540-2
  • Complex calculations for NZÚ (Czech grant program)

Using the program, it is possible to calculate the following parameters of the structures:

  • Heat transfer coefficient according to ČSN 73 5040-2 and ČSN EN ISO 6946
  • The heat transfer coefficient of the windows and doors according to ČSN EN ISO 10077-1
  • The lowest indoor surface temperature (internal surface temperature factor) according to ČSN 73 0540-4
  • The lowest indoor surface temperature (internal surface temperature factor) according to ČSN EN ISO 13788
  • Decrease of floor surface temperature according to ČSN 73 0540-4
  • Amount of condensed water vapor inside the structure and annual balance of condensation and evaporation of water vapor inside the structure according to ČSN EN ISO 13788
  • Amount of condensed water vapor inside the structure and annual balance of condensation and evaporation of water vapor inside the structure according to ČSN 73 0540-4
  • Moisture content in the wooden elements in the structure for the examination of the biological risk of built-in wooden elements
  • Temperature and relative air humidity at the connection of layers of the building components for detailed risk assessment of moisture defects (eg condensation or growth of mold above the suspended ceiling or condensation on the lower face of the double-skin roof)
  • Drying of construction according to ČSN EN ISO 13788
  • Dynamic parameters of structures according to ČSN EN ISO 13786

The calculations and assessments are carried out according to the following standards:

  • ČSN 73 0540-1: 2005 - Thermal protection of buildings - Part 1: Terminology
  • ČSN 73 0540-2: 2011 - Thermal protection of buildings - Part 2: Requirements
  • ČSN 73 0540-3: 2005 - Thermal protection of buildings - Part 3: Design values of quantities
  • ČSN 73 0540-4: 2005 - Thermal protection of buildings - Part 4: Calculation methods
  • EN ISO 6946: 2008 - Building components and building elements - Thermal resistance and thermal transmittance - Calculation method
  • EN ISO 10077-1: 2007 - Thermal performance of windows, doors and shutters. Calculation of thermal transmittance. Part 1: General 
  • ISO 13788: 2013 - Hygrothermal performance of building components and building elements - Internal surface temperature to avoid critical surface humidity and interstitial condensation - Calculation methods
  • ISO 13786: 2008 - Thermal performance of building components - Dynamic thermal characteristics - Calculation methods
