The COVID-19 pandemic has impacted people’s lifestyle, the global economy and the environment on an unprecedented level. People are now spending 80-90% of their time in confined indoor spaces, staying indoors for longer period of time and working more from home.
As a result, the measurement and management of indoor air quality is in the spotlight now widely considered to be among the most important health & safety concern for building operations.
An adequate ventilation rate is necessary for reducing the infection risk in confined spaces such as offices, residential areas, public buildings like malls, restaurants, museums, and public transportation.
Dilution of the contaminants inside confined spaces should be the prime consideration to reduce exposure risk and maintain a healthy environment as it is common knowledge of how quickly and dramatically indoor air quality can change over the course of hours and minutes.
In fact, a recent study suggested that enhancing indoor air quality (IAQ) could be as effective in reducing aerosol transmission of viruses as vaccinating 50-60% of the population. As tenants tentatively emerge back into their places of work, landlords are challenged with optimising the operational performance of buildings to the greatest extent possible, in conjunction with the enactment of behavioural change, to minimise risk and give their tenants peace of mind.
Buildings are running blind
However, most buildings are running blind, unable to tell occupants how often indoor air is actually being changed or how clean it is. Without any sort of data, buildings are being ventilated as much as possible, often exposing occupants to temperature, humidity and outdoor pollutant levels that compromise the immune system, all the while increasing greenhouse gas emissions. Responses are based on best guess estimates and hopeful checklists.
One solution is to use EC fan and integrating it with IoT. Leveraging on this technology will enable organizations to optimize their operations at all levels, improve decision making, and achieve several benefits.
