CAVITY

CAVITY is a program for calculating flow velocity, temperature and humidity conditions in the ventilated air cavities. The results can be compared with the requirements set in Czech standard ČSN 73 0540-2.

Using the program, you can create:

  • Assessment of ventilated air cavities according to ČSN 73 0540-2
  • Determination of temperature in the ventilated air layer
  • Determination of relative humidity in the ventilated air layer
  • Assessment of the temperature factor of the outer shell of the double-skinned structure

Calculations are based on 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 the building - Part 4: Calculation methods
    ČSN 73 0549: 1977 - Thermal performance of building structures and buildings - Calculation methods
    EN 1991-1-4: 2011 - Eurocode 1: Structural loads - Part 1-4: General loads - Wind load
