“Sick Building Syndrome” (SBS) is a term that has gained prominence in the realm of indoor environmental quality, particularly in the context of the UK. This refers to a range of symptoms experienced by occupants of a building, often associated with poor indoor air quality. This post begins to lock into the intricacies of Sick Building Syndrome and emphasises the pivotal role that effective ventilation plays in its prevention and mitigation.

Defining Sick Building Syndrome in the UK:
Symptoms and Prevalence:
Sick Building Syndrome encompasses a spectrum of non-specific health issues, including headaches, fatigue, respiratory irritation, and other symptoms, which individuals experience while spending time in a particular building. The prevalence of SBS has been noted in various indoor environments, ranging from offices and schools to domestic dwellings. Symptoms can include (Consult a medical professional for further support):
Headache
Runny nose
Dry, itchy skin
Dry, sore eyes or throat
Coughing or wheezing
Skin rashes
Tiredness or difficulty concentrating
Contributing Factors:
Multiple factors contribute to the manifestation of SBS, such as inadequate ventilation, poor air quality, and the presence of indoor pollutants. The challenge lies in identifying and addressing these factors to create healthier indoor spaces.

Ventilation as a Key Mitigating Factor:
Diluting Indoor Pollutants:
One of the primary causes of Sick Building Syndrome is the accumulation of indoor pollutants. Effective ventilation ensures a continuous supply of fresh outdoor air, diluting and expelling harmful pollutants, including volatile organic compounds (VOCs), particulate matter, and other potential irritants.
Controlling Humidity:
In the UK, where dampness and high humidity levels are common, ventilation plays a crucial role in preventing the conditions conducive to mould growth. Mould spores are known contributors to respiratory issues, and proper ventilation helps maintain optimal humidity levels, mitigating the risk of mould-related problems.
3, Energy-Efficient Building Practices and SBS:
The Paradox of Airtight Buildings:
The push for energy efficiency in modern construction has led to the creation of more airtight structures. While this significantly reduces energy consumption, it also raises concerns about indoor air quality. Effective ventilation strategies become paramount in balancing the energy efficiency of buildings with the need for a healthy indoor environment.
Striking a Balance:
Recognising the tension between airtightness and ventilation, it is imperative to adopt ventilation systems that ensure optimal air exchange without compromising the energy-efficient design principles of a building. Striking this balance is essential for preventing the onset of Sick Building Syndrome. VENTI is seeing a rise in clients requesting MVHR systems in their homes when building or retrofitting a property. There is also a considerable rise in the installation of decentralised ventilation systems.

Regulatory Framework and Guidelines:
Building Regulations and Indoor Air Quality:
The UK’s Building Regulations acknowledge the importance of indoor air quality. Ventilation standards are outlined in regulations such as Part F (See our blog on Part F here), which sets criteria for air supply and extraction to maintain a healthy indoor environment. Compliance with these regulations is integral to preventing and alleviating Sick Building Syndrome.
Occupational Health and Safety:
Occupational health guidelines in the UK underscore the importance of ensuring a safe and healthy working environment. Proper ventilation is a key component of these guidelines, emphasising the duty of employers to provide conditions that safeguard the well-being of occupants. A well heating and ventilated work environment has been scientifically proven to increase performance.
Sick Building Syndrome in the UK underscores the intricate relationship between indoor air quality and occupant health. As the built environment continues to evolve, with a growing emphasis on energy efficiency, the role of effective ventilation becomes paramount. Recognising the symptoms and contributing factors of SBS, and implementing robust ventilation strategies in accordance with regulatory frameworks, is imperative for creating indoor spaces that promote not only energy efficiency but also the health and well-being of those who inhabit them. In essence, ventilation stands as a crucial pillar in the foundation of healthier and more sustainable buildings in the United Kingdom.
