One of the lessons of the Covid pandemic was the importance of good building ventilation. As buildings have become increasingly airtight in response to the need to reduce carbon dioxide emissions, the level of pollutants indoors increased. There are multiple internal sources of toxic emissions in buildings, most of which are poorly regulated. These include the emission of volatile organic compounds (VOCs) from building materials, furnishings, paints, solvents, cleaning materials and personal care products. For most of these products there are no standards limiting their VOC content.
People spend most of their time indoors (80-90%) and are exposed to a range of air pollutants in different environments. The World Health Organization (WHO) and the UK Health Security Agency (UKHSA) publish health based guidelines on many of the common indoor pollutants, but there are no legal requirements to meet them. There are weak requirements in the building regulations for new buildings and worker exposure limits under health and safety legislation, but these are not protective for the general public.
Many developers now signup to voluntary building standards to ensure that there are good indoor environments as a key selling point for their developments. Research shows that the benefits of improving the health and wellbeing of building occupant can be significant, for example by increasing productivity.
