Most people worry about indoor air quality amidst the COVID-19 pandemic
A survey ordered by Vaisala, a world-leading measurement technology company, shows that people would feel safer with more data on indoor air quality. The survey, which included over 4,000 respondents in the USA, France, Germany, and Finland, was conducted in the summer of 2021, studying people’s concerns regarding indoor air during the COVID-19 pandemic. More than one third of the respondents are concerned about the indoor air quality in their place of work, and more than half said that concerns with indoor air quality impacts their motivation to visit public spaces. Around two thirds of respondents also said that these concerns impact their motivation to travel.
“Vaccination rates are high in the surveyed countries, but the survey revealed high levels of concern with air quality in indoor spaces. We believe this is because, intuitively, people understand that infection risk is higher in indoor spaces where people are in close proximity with each other, and where ventilation is insufficient,” saysAnu Kätkäfrom Vaisala’s product management.
“When people spend too long in a poorly ventilated space, their exhaled breath causes carbon dioxide (CO2) levels to rise. Higher levels of CO2 impact people’s well-being, health and performance, but importantly, monitoring CO2 levels can highlight when the risk of COVID-19 transmission is high and better ventilation is required. By monitoring CO2 levels in indoor spaces, organizations can therefore provide the reassurance that the survey respondents need,” Kätkä explains.
受访者需要更多有关工作场所室内空气质量的数据
在所有受访者中，芬兰人最有信心重返工作岗位：71％的芬兰受访者对返回工作场所感到安全。70％的法国受访者对返回感到安全。65％的美国受访者，只有55％的德国受访者。
50% of all respondents said that they would feel safer about returning to work with more information about indoor air quality.
Indoor air qualitycan be monitored with instruments that measure, among other parameters, CO2, humidity, and temperature. These parameters can be used to automatically inform ventilation and building management systems so that indoor air quality can be optimized.
“室内空气不仅会影响接触空气疾病，而且会影响员工的能量水平，因为呼气的呼吸增加了二氧化碳水平，从而增加了嗜睡，”Kätkä继续说道。
Indoor air quality monitoring needed in public spaces
该调查还研究了人们对公共场所室内空气质量的看法，例如购物中心，体育设施和公共交通工具。总体而言，人们比在工作地点更关心公共区域的室内空气质量。所有受访者中有50％希望在工作场所中提供更多信息，而60％的受访者希望更多有关公共空间室内空气质量的信息。
公共场所中室内空气质量的关注转化为不愿旅行，有65％的受访者说，公共场所室内空气质量的担忧会影响他们的旅行动机。
学校，购物中心，餐馆，车站和机场all benefit from indoor air quality monitoring. Viruses travel faster in dry air, but humidity can make people feel unwell. It is therefore important to monitor and maintain optimal conditions, and to share the monitoring data with all stakeholders, including staff and members of the public.
大多数人都希望对室内空气进行更准确的数据
Based on the survey results, indoor air quality is a concern in the mind of at least every third person, and more than half of all the respondents want more information and data on air quality inside those places where they spend time. This means that facility managers face important decisions.
“近年来，许多国家已经实施了有关监测室内空气质量参数（例如CO2）的法规。这些法规旨在确保最佳空气质量，但为了实现这一目标，准确和基于科学的数据至关重要。”Kätkä解释说。
Reliable measurement instrumentsperform a key role in decision making to prevent the spread of diseases and protect people’s health. The prerequisite for healthy indoor air is efficient ventilation and空调that prevents diseases from spreading, keeps the mind clear, and ensures a healthy environment.
