The idea of building an experimental house for ventilation research arose in connection with the involvement of the Department of Thermomechanics and Environmental Engineering, Faculty of Mechanical Engineering, Brno University of Technology in the project of the 5th EU Framework Program called RESHYVENT (RESidential HYbrid VENTilation). The experimental house was originally intended only to study hybrid ventilation in the conditions of the Czech Republic. However, the idea of building a simple building that would be more of a laboratory than a residential house was soon abandoned. Subsequently, a new plan was formulated, namely to build a demonstration building the size of a family house, which with its thermal technical properties would significantly exceed the requirements of applicable standards and be equipped with a modern hybrid ventilation system and other energy saving systems for heating and ventilation. The main idea of the new plan was for the experimental house to serve the general professional and lay public as a demonstration project for the implementation of controlled ventilation in the conditions of the Czech Republic.
The hybrid ventilation system for the temperate climate zone, developed within the RESHYVENT project by a consortium of Dutch companies in cooperation with the TNO Institute of Applied Research, was used as the basis of the ventilation system. For the conditions of the Czech Republic, this ventilation system was supplemented by a heat pump for heat recovery from the ventilation air and a solar chimney for passive cooling in the summer. Due to the limited time available for the construction of the house, a wooden building with good thermal insulation was chosen.
The experimental house for ventilation research will serve both for educational and demonstration purposes, as well as for the study of controlled ventilation in the conditions of the Czech Republic. An extensive measuring system is installed in the house, which monitors a number of parameters needed to evaluate the benefits of controlled ventilation both in terms of air quality and energy savings.
In 1. floor there is a presentation room (living room), which will be gradually equipped with the necessary technology to acquaint interested professionals and the general public with the installed ventilation system and other HVAC systems, as well as with the results of ongoing measurements and experiments.
