PH Water Technologies are now able to supply & install remote “Indoor Air Quality Monitoring” sensors.
The quality of “breathed air” within a room is continually analysed and accessible to the user in real time via a slick dashboard on their mobile phone or PC and by using a clever algorithm even provides a “Virus Infection Risk Score”.
IAQ measures the health and comfort of a building’s interior air, focusing on the presence of contaminants such as particulate matter (on which viruses such as SARS-CoV-2 are sometimes found), carbon monoxide and volatile organic compounds (VOCs). Particulate matter is a combination of solid particles and liquid droplets that may include dust, pollen and smoke. VOCs are ubiquitous (and often odorous), arising from cleaning agents, air fresheners and new carpets. HVAC strategies can have a significant impact on reducing these contaminants in the built environment.
Building wellness and IAQ is being increasingly embedded into corporate wellbeing strategies to deliver a healthier and happier work environment. This results in significant returns on investment for companies, including fewer absences, higher employee retention rates and more engaged and productive workers
Common sources of poor indoor air quality include insufficiently maintained HVAC systems, wood and coal stoves, non-vented gas heaters, environmental tobacco smoke, and vehicle exhaust emissions. When designing or managing a building, it’s important to note things like materials used in construction, carpeting, furniture, and choice of solvents or cleaning supplies. Inadequate ventilation is particularly crucial, as poorly ventilated spaces (along with environmental factors such as temperature and humidity) can amplify the pollutant concentration.
Gas and respirable particulates in the air are the primary sources contributing to poor indoor air quality. Accurate indoor air quality monitoring alerts residents and building owners to the level and nature of pollution, enabling corrective action.
The latest government guidelines is that all Classrooms in England are to be fitted with CO2 monitors when state schools and colleges reopen after the summer holidays, in an effort to improve ventilation and combat the spread of Covid. www.theguardian.com
The HSE have also issued updated guidance on the importance of ventilation during the COVID 19 pandemic and identifying poorly ventilated areas using monitors. www.hse.gov.uk/coronavirus
Another article identifies that airborne viruses recycled through a low-grade ventilation system likely created Germany’s first super-spreader event of the Covid-19 pandemic. www.theguardian.com
