BS 40102 – A Two Part Standard on Health, Wellbeing, Thermal Comfort, and Indoor Air Quality

Sotirios Papathanasiou2 Comments

The BS 40102, a fresh standard introduced in 2022 (draft released) by the British Standards Institute, focuses on assessing the health, wellbeing, and indoor environmental quality (IEQ) of buildings. It incorporates an updated best-practice method for addressing thermal comfort, indoor air quality, and overheating in buildings.

Regarding the new exposure limits, they are derived from various sources, including the DEFRA Daily Air Quality Index, WHO Air Quality Guidelines 2021, BREEAM and WELL Guidelines, and British Standard BS EN 16798-1.

Part 1 – Health and Wellbeing in Buildings

  • BS 40102-1 gives recommendations for the measuring, monitoring and reporting of the well-being and IEQ performance of an occupied building and the associated building services.
  • BS 40102-1 provides an evaluation and rating system (IEQ performance score), the aim of which is to enhance IEQ, to create healthier buildings and improve the well-being of building occupants; including but not limited to staff, visitors, tenants and customers.

Interview – Airport Series: #2 Living With Airport Pollution: A Remote Community’s Struggle with Military Operational Area

Sotirios Papathanasiou1 Comment

For privacy reasons the name of the interviewee has been changed.

Jake lives in a remote desert community located in a Military Operational Area (MOA) in the southwestern United States. His town is 90-120 miles away from two major military airports that are the main source of noise and air pollution in our area.

His family moved there in 2021, attracted to the quiet and scenic landscape. However, they soon noticed increased aviation activity, especially overnight flights that interrupt sleep multiple times a night. Although he can’t confirm an increase in flights, the noise pollution seems worse, with persistent droning lasting for hours in the early mornings and evenings. The noise easily penetrates our brick home.

The worst pollution comes from noisy C130s cargo planes, fighter jet passes, and helicopters, often conducting night training and looping for hours across vast distances. He has calculated these planes can be heard indoors from over 20 miles away. The noise affects his sleep, requiring daytime naps which in turn impact his work. He has experienced vestibular symptoms and severe vibration sensitivity both of which were induced by low-flying military helicopters at his old residence where he had around 10 flyovers a day. Each flyover could be multiple helicopters. from the noise exposure. Weekend nights are a respite they look forward to.

Interview – Airport Series: #1 The Growing Concerns of Van Nuys Airport and Its Impact on Local Community

Sotirios PapathanasiouLeave a comment

I recently learn from Sue, a resident of Los Angeles, who is living in the shadow of the Van Nuys Airport (VNY) that the air quality of the area and mental health of the residents have been affected dramatically. She shared with me the growing concerns regarding the environmental and health impacts of the airport’s operations, particularly due to the increasing number of private and charter jets.

According to Sue over the past few years, the VNY has essentially transformed into a commercial airport due to the influx of private and charter jets. This brings with it an incessant noise pollution problem, as there’s no curfew and flights come in all day and night. And, they are under the most congested airspace in the world, with five airports in the LA area, all converging over them.

Although the airport has been around since the 1920s the changes, in recent years are drastic. Sue lives in that area since mid 80’s. They are now literally feet away from dozens of jets that emit toxic fumes into their homes, schools, and lungs. It was not like this up until a few years ago.

The Intricate Relationship Between Plastic Pollution, Air Pollution, and Human Health

Sotirios PapathanasiouLeave a comment

The world is grappling with an abundance of environmental challenges, two of the most critical being plastic pollution and air pollution. Although seemingly disparate, these two issues are more intertwined than we might think, especially when considering their impact on human health. Recent studies have shed light on the presence of microplastics in the human body, a discovery that links plastic pollution and air pollution in a direct and alarming way.

Understanding Plastic and Air Pollution

Plastic pollution refers to the accumulation of plastic objects and particles in the Earth’s environment, including our oceans, lands, and even the air we breathe. This pollution takes many forms such as bags, bottles, microbeads, and tiny particles known as microplastics (less than 5mm in size).

Gender Differences in Exposure and Health Risks of Air Pollutants

Sotirios PapathanasiouLeave a comment

Air pollution, a significant environmental health issue, affects everyone. However, there is growing research evidence showing that the health effects of air pollution may not be the same for men and women. This difference is driven by biological, socio-economic, and occupational factors that can influence exposure levels and health outcomes.

Biological Differences

In terms of biological differences, women have a higher percentage of body lipids than men, which can accumulate fat-soluble pollutants. This can lead to a higher concentration of certain pollutants in women, potentially increasing their risk of health effects. For example, a study published in the journal ‘Environmental Research’ in 2018 showed that women exposed to polycyclic aromatic hydrocarbons (PAHs), a group of chemicals released from burning coal, oil, gasoline, and tobacco, had higher levels of DNA damage than men exposed to the same levels of PAHs.

Air Quality & Life Span

Sotirios PapathanasiouLeave a comment

Most of us have heard of Bryan Johnson, the Silicon Valley tech mogul who sold his startup for a reported $800 million. But what you may not know is that Johnson is taking an unconventional approach to extending his life span. Excellent indoor air quality is one of the regimes that he is paying very close attention to.

The process, which will cost Johnson a reported $2 million a year, is expected to include a variety of lifestyle changes and medical treatments. Of course, Johnson will likely focus on the basics – healthy eating and exercise. But he’ll also be looking at cutting-edge treatments, such as stem cell therapy and gene therapy, to give his body the best chance of staying healthy.

Moreover, it’s not just about the treatments – Johnson also plans to invest heavily in improving his home environment (IAQ). He wants to make sure his home is free from pollutants and that the air he breathes is of the highest quality. He’s already installed a HEPA air filter and plans to invest in monitoring devices that will allow him to track his health and make informed decisions about the treatments and lifestyle changes he’s making. This will give him an unprecedented level of control over his body and allow him to make the most out of his investment.
