Air Quality & Ventilation
The links between indoor air quality (IAQ), poor ventilation and health outcomes are well established. The air we breathe has a direct impact on our health. If we are to "tighten" up dwellings to reduce draughts, emissions and energy costs, it is vital we understand how to ventilate to maintain a healthy indoor environment.
There are a number of indoor air pollutants found in the home, some more of a problem than others. By removing these at source through adequate ventilation we can help maintain the health of occupants and the dwelling.
Although not technically a pollutant, excess moisture in buildings can cause severe problems if not controlled. Water vapour migrating in to the building envelope can damage the structure and fabric of dwellings, which may not be immediately obvious. Furthermore, excess moisture condensing on cold surfaces can lead to mould and fungal spores, which if exposed to for prolonged periods can have detrimental impacts on health.
We must therefore understand how to ventilate adequately whilst maintaining good thermal comfort levels and achieving affordable warmth. Striking this balance can prove difficult but an understanding of the dwellings current ventilation rate is the starting point. Only then can we implement an appropriate ventilation strategy, designed for the building and the occupants.
