Although the sample sizing as well as brief monitoring period provide a snap-shot of your situation in Scottish dwellings to put up-2009 creating laws which make the most of frequent “natural ventilation” possibility with trickle ventilators in window frames and intermittent extract lovers in moist rooms, the final results provide a important insight the place Earlier there was none.

Local exhaust ventilation addresses The difficulty of keeping away from the contamination of indoor air by specific large-emission resources by capturing airborne contaminants right before They may be distribute in the environment.

The above mentioned summarises just a subset of obtainable literature but serves For example that absolute CO2 concentrations and ventilation charges are starting to arise in creating restrictions, and highlights a range of earlier experiments into how occupants connect with ventilation components, And exactly how indoor air quaility was calculated, these factors served to inform the current study.
