Two examples include air-facet economizer cooling and ventilative pre-cooling. In other instances, ventilation for indoor air high quality contributes to the necessity for – and Power use by – mechanical heating and cooling equipment. In incredibly hot and humid climates, dehumidification of ventilation air could be a very Electrical power-intensive procedure.
Techniques and architectural capabilities used to ventilate properties and structures Obviously contain, but will not be restricted to:
The research implies that inadequate ventilation could be endemic in new Create dwellings throughout Scotland.
