As minimum CO2 concentration the value <strong>for</strong> ambient air, ������ � ��� ����� ����� ,<br />
is taken. As maximum a value <strong>of</strong> ������� � ���� ���� �<br />
�����<br />
will give the highest weight<br />
<strong>of</strong> ����. This value is proposed as a maximum <strong>for</strong> hygienically acceptable air quality<br />
[13]. A comparison with the equation given in the Europe<strong>an</strong> Guidelines <strong>for</strong> Ventilation<br />
Requirements in Buildings [14] is seen in Figure 8.7.<br />
