DYNAMIC SIMULATION OF THE EFFECT OF VENTILATION ON THE THERMAL MICROCLIMATE IN A WOODEN BUILDING

Abstract

The design of a suitable ventilation method for buildings aims primarily to improve the quality of the indoor environment of buildings and thus to influence individual parameters of the indoor environment such asCO2concentration, air purity, the required amount of fresh air according to the proposed operation of the building, temperature and humidity. Proper design and installation of a forced ventilation system with heat recovery can significantly reduce the energy required for heating or cooling. The paper focuses on the ventilation of a building in summer and its effect on the indoor air temperature, which is an important parameter in the assessment of thermal stability. The building under consideration is a building designed using lightweight building structures that meet the standard requirements for the thermal technical properties of a building in the passive standard. The computer program DesignBuilder will be used for the calculation, which allows the assessment of alternative ventilation solutions under identical climatic conditions by means of dynamic simulation on a 3D model of the building. A critical room where the highest daily temperatures are reached will be used for the evaluation.
