Abstract

Natural ventilation performance of family building in cold climate during windless time

Highlights

  • The economic realities in Poland and building construction common practices over the years favor the cheapest ventilation systems which are natural ventilation

  • The measurements were carried out in a test apartment of a family detached house located in a cold climate

  • The measurement campaign was performed under transient climate conditions: 1. The experimental results confirmed the assumption about discharge coefficient

Summary

INTRODUCTION

The economic realities in Poland and building construction common practices over the years favor the cheapest ventilation systems which are natural ventilation. The Authors investigated stack ventilation effect for residential house with multi-chimneys configuration and a tilted window They compared in detail mass balance and took into account changes of density. Ventilation performance indicators are to provide the information concerning indoor air parameters in a room or a building It is important proper information about realistic climate data of local climate conditions, but usually is not. The major contribution of the paper is the experimental determination of the natural (stack) ventilation in residential apartment with chimney configuration and a window with inlet gap on the air exchange rate. These results can be used to help design control strategies for simple natural ventilation schemes
