Zespół chorego budynku
Etiologia i przyczyny

Zespół chorego budynku (SBS) to zespół niespecyficznych objawów, takich jak podrażnienie oczu, nosa, gardła, zmęczenie psychiczne, bóle głowy, nudności i podrażnienie skóry, które pojawiają się podczas przebywania w określonym budynku i ustępują po jego opuszczeniu. Główną przyczyną jest niewystarczająca wentylacja – standardy wentylacji spadły w latach 70. z 15 cfm do 5 cfm na osobę, co jest niewystarczające; obecnie ASHRAE zaleca minimum 15 cfm, a w przestrzeniach biurowych 20 cfm powietrza zewnętrznego na osobę. Inne czynniki to zanieczyszczenia chemiczne (VOC, formaldehyd, ozon, dym tytoniowy), biologiczne (pleśnie, bakterie, wirusy) oraz fizyczne (temperatura, wilgotność, oświetlenie, hałas). Czynniki psychospołeczne, takie jak stres zawodowy i niskie morale, również istotnie wpływają na nasilenie objawów. SBS jest szczególnie częsty w budynkach z klimatyzacją i w sektorze publicznym, a kobiety oraz osoby z historią alergii są bardziej podatne na rozwój zespołu.

Zespół chorego budynku – etiologia, przyczyny, czynniki wywołujące

Zespół chorego budynku (ang. Sick Building Syndrome, SBS) to stan, w którym osoby przebywające w danym budynku doświadczają różnorodnych niespecyficznych objawów zdrowotnych, które wydają się być bezpośrednio związane z czasem spędzonym w tym budynku, jednak bez możliwości zidentyfikowania konkretnej choroby lub jednoznacznej przyczyny. Objawy te zwykle ustępują po opuszczeniu budynku, chociaż w niektórych przypadkach efekty neurotoksyczne mogą utrzymywać się dłużej.12

SBS staje się coraz poważniejszym problemem zawodowym, który zmniejsza wydajność pracy i zwiększa absencję. Zgłaszane dolegliwości mogą być zlokalizowane w konkretnym pomieszczeniu lub strefie budynku albo mogą występować w całym obiekcie. Według Światowej Organizacji Zdrowia (WHO), która zdefiniowała to zjawisko w 1983 roku, SBS obejmuje „zbiór niespecyficznych objawów, w tym podrażnienie oczu, nosa i gardła, zmęczenie psychiczne, bóle głowy, nudności, zawroty głowy i podrażnienie skóry, które wydają się być związane z przebywaniem w określonych miejscach pracy”.13

Niespecyficzna etiologia zespołu chorego budynku

Zespół chorego budynku jest szczególny, ponieważ mimo wyraźnych objawów, nie można zidentyfikować konkretnej choroby ani jednoznacznej przyczyny. Jest to złożony problem, który prawdopodobnie wynika z kombinacji wielu czynników związanych z jakością środowiska wewnętrznego. SBS należy odróżnić od chorób związanych z budynkiem (ang. Building-Related Illness, BRI), które mają określoną przyczynę i mogą być zdiagnozowane medycznie.24

Badania nad przyczynami SBS trwają od lat 70. XX wieku, jednak nadal nie udało się wskazać jednego czynnika odpowiedzialnego za wszystkie przypadki. Tacy badacze jak Goldman zauważyli, że pojawienie się objawów SBS korelowało z rozwojem powojennych, energooszczędnych, szczelnych budynków, kiedy głównym zadaniem architektów było utrzymanie niskich kosztów.5

Warto zauważyć, że choć SBS nie powoduje poważnych uszkodzeń zdrowia, to prowadzi do potencjalnie problematycznych konsekwencji, takich jak zmniejszenie produktywności, absencja pracowników oraz koszty związane z badaniem i naprawą budynków.67

Czynniki fizyczne i środowiskowe przyczyniające się do SBS

Nieadekwatna wentylacja

Niewystarczająca wentylacja jest jednym z najczęściej wymienianych czynników przyczyniających się do zespołu chorego budynku. W około 52% przypadków SBS badanych przez Narodowy Instytut Bezpieczeństwa i Zdrowia w Pracy (NIOSH) stwierdzono, że problemy z wentylacją były główną przyczyną.89

Podczas kryzysu energetycznego w latach 70. standardy wentylacji zostały zredukowane z 15 cfm (stóp sześciennych na minutę) na osobę do zaledwie 5 cfm, co okazało się niewystarczające do utrzymania zdrowia i komfortu osób przebywających w budynkach. Obecnie Amerykańskie Stowarzyszenie Inżynierów Ogrzewnictwa, Chłodnictwa i Klimatyzacji (ASHRAE) zaleca minimum 15 cfm powietrza zewnętrznego na osobę, a 20 cfm w przestrzeniach biurowych.1011

Problemy z wentylacją mogą wynikać z:

  • Niespełniania obowiązujących norm i standardów, takich jak te publikowane przez ASHRAE12
  • Problemów z instalacją lub konserwacją systemów HVAC12
  • Nieuwzględnienia wymagań wentylacyjnych podczas remontów lub zmian w sposobie użytkowania przestrzeni12
  • Niewłaściwej dystrybucji powietrza do osób w budynku13

Badania wykazały, że budynki z klimatyzacją mają wyższy wskaźnik objawów SBS niż budynki wentylowane naturalnie, a objawy częściej występują w budynkach sektora publicznego niż w budynkach sektora prywatnego.1415

Zanieczyszczenia chemiczne

Zanieczyszczenia chemiczne są istotnym czynnikiem przyczyniającym się do SBS i można je podzielić na te pochodzące ze źródeł wewnętrznych i zewnętrznych.10

Zanieczyszczenia ze źródeł wewnętrznych:

  • Lotne związki organiczne (VOC) emitowane przez kleje, tapicerkę, wykładziny, kopiarki, wyroby z drewna, pestycydy, środki czyszczące108
  • Formaldehyd emitowany przez meble i podłogi drewniane16
  • Ozon z kopiarek i drukarek laserowych1718
  • Dym tytoniowy zawierający różnorodne toksyczne zanieczyszczenia powietrza8
  • Środki czyszczące uwalniające związki takie jak toluen i benzen818
  • Emisje z materiałów budowlanych, mebli i wykończenia wnętrz719

Badania wykazały, że reaktywne lotne związki organiczne, takie jak aldehydy i węglowodory halogenowane, są związane z rosnącym poziomem objawów SBS.20

Zanieczyszczenia ze źródeł zewnętrznych:

  • Spaliny z pojazdów silnikowych1021
  • Zanieczyszczenia z otworów wentylacyjnych instalacji hydraulicznych10
  • Wyrzuty z budynków (łazienki i kuchnie)10
  • Zanieczyszczenia z pobliskich zakładów przemysłowych2

Te zanieczyszczenia mogą przedostawać się do budynku przez niewłaściwie zlokalizowane otwory wentylacyjne, okna oraz inne otwory.1312

Zanieczyszczenia biologiczne

Zanieczyszczenia biologiczne mogą powodować szereg objawów związanych z SBS i obejmują:1013

  • Pyłki roślin10
  • Bakterie10
  • Wirusy10
  • Grzyby i pleśnie1022
  • Odchody owadów i zwierząt17

Zanieczyszczenia biologiczne rozwijają się głównie w miejscach o nadmiernej wilgoci lub wysokiej wilgotności, takich jak stojąca woda w kanałach, nawilżaczach, tacach odpływowych lub miejscach, gdzie woda zgromadziła się na płytkach sufitowych i izolacji.2324

Badania wykazały, że niektóre pleśnie, takie jak Fusarium oraz Penicillium i Stachybotrys, produkują toksyny, które mogą być szkodliwe dla zdrowia i są ściśle związane z SBS. Mykotoksyny te mogą wnikać głęboko do płuc i dróg oddechowych, powodując poważne dolegliwości i osłabiając układ odpornościowy.252627

Z badań przeprowadzonych przez Fiska i Mudarriego wynika, że 21% przypadków astmy w Stanach Zjednoczonych było spowodowanych wilgotnymi środowiskami z pleśnią występującymi we wszystkich środowiskach wewnętrznych, takich jak szkoły, budynki biurowe, domy i mieszkania.28

Inne czynniki fizyczne budynku

Oprócz głównych czynników związanych z jakością powietrza wewnętrznego, do SBS przyczyniają się również inne fizyczne aspekty budynku:719

  • Temperatura i wilgotność – zbyt wysoka temperatura, niska wilgotność lub częste zmiany temperatury w ciągu dnia mogą powodować dyskomfort i nasilać objawy SBS297
  • Oświetlenie – słabe oświetlenie, migotanie świateł, brak dostępu do światła naturalnego297
  • Hałas – zarówno niski, jak i wysoki poziom hałasu, stały lub przerywany30
  • Promieniowanie elektromagnetyczne z urządzeń elektronicznych, takich jak komputery, mikrofale i telewizory, które jonizują powietrze31
  • Pył, kurz i włókna unoszące się w powietrzu29
  • Obecność monitorów komputerowych z niską jakością obrazu, powodujących nadmierne obciążenie oczu17

Badanie przeprowadzone w 2015 roku dotyczące związku SBS z zanieczyszczeniami powietrza wewnętrznego w budynkach biurowych w Iranie wykazało, że wraz ze wzrostem stężenia dwutlenku węgla w budynku, zwiększały się objawy takie jak nudności, bóle głowy, podrażnienie nosa, duszność i suchość gardła.2832

Czynniki psychospołeczne i organizacyjne

Badania wskazują, że czynniki psychospołeczne i organizacyjne odgrywają istotną rolę w rozwoju i nasileniu objawów SBS. Aspekty te są często pomijane, ponieważ skupiamy się głównie na fizycznych właściwościach budynku.1415

Do głównych czynników psychospołecznych należą:

  • Stres zawodowy – nadmierny stres w pracy lub niezadowolenie z pracy14
  • Złe relacje interpersonalne w miejscu pracy14
  • Słaba komunikacja między pracownikami i kierownictwem14
  • Niska satysfakcja z pracy i niskie morale w miejscu pracy33
  • Brak kontroli nad własną pracą33
  • Specyficzne czynniki stresowe związane z pracą, które są istotnie związane z konkretnymi objawami SBS. Obciążenie pracą i konflikty w pracy są znacząco powiązane z ogólnymi objawami (ból głowy, nietypowe zmęczenie, uczucie zimna lub nudności)34

Istnieje wyraźna korelacja między rodzajem wykonywanej pracy a częstością występowania objawów SBS. Objawy są częściej obserwowane u osób wykonujących prace biurowe niż u osób zajmujących stanowiska kierownicze, co prawdopodobnie wynika z lepszych warunków pracy dla kadry kierowniczej. Częstość występowania objawów jest najwyższa wśród pracowników biurowych wykonujących rutynowe zadania.1415

Badania sugerują, że stres związany z pracą i niezadowolenie są prawdopodobnie ważniejszymi przyczynami objawów niż czynniki fizyczne i chemiczne w środowisku wewnętrznym. Jednak późniejsze badania wykazały, że chociaż SBS był związany z niskim wsparciem ze strony przełożonych i postrzeganiem złych fizycznych warunków pracy, istniał również związek ze złą jakością powietrza, nawet po uwzględnieniu środowiska psychospołecznego.1533

Czynniki demograficzne i indywidualne

Istnieją pewne czynniki demograficzne i indywidualne, które mogą wpływać na podatność na zespół chorego budynku:14

  • Płeć – objawy SBS są częstsze u kobiet niż u mężczyzn, prawdopodobnie dlatego, że więcej kobiet pracuje na stanowiskach sekretarskich, są bardziej świadome swojego zdrowia lub mniejsza dawka zanieczyszczeń jest wymagana do wystąpienia efektów1435
  • Historia chorób alergicznych – objawy SBS u dorosłych były związane z historią alergicznego nieżytu nosa, egzemy i astmy28
  • Czas spędzony przy monitorach komputerowych – niektóre badania wykazują niewielki związek między czasem spędzonym przed jednostkami wyświetlania wizualnego (VDU) a zespołem chorego budynku36

Według niektórych badań, kobiety cisgender mogą być trzy razy bardziej narażone na doświadczenie SBS niż mężczyźni cisgender.25

Czynniki związane z domem mieszkalnym

Zespół chorego budynku może występować również w środowisku domowym. Czynniki związane z domem, które mogą przyczyniać się do SBS, obejmują:34

  • Rodzaj podłogi – podłogi laminowane mogą powodować większe narażenie na chemikalia i więcej objawów SBS w porównaniu z podłogami kamiennymi, płytkami i betonowymi34
  • Niedawne remonty i nowe meble (w ciągu ostatniego roku) również powiązano ze zwiększonymi objawami34
  • Wilgotność i powiązane czynniki34
  • Posiadanie zwierząt domowych34
  • Obecność karaluchów34

Wpływ zmian klimatycznych i energetycznych na SBS

Zmiany klimatyczne i dążenie do oszczędności energii mają istotny wpływ na występowanie zespołu chorego budynku. Jak stwierdzono w jednym z badań, przyczyną SBS są w dużej mierze zmiany w projektowaniu budynków i wentylacji wywołane kryzysem energetycznym w latach 70.3337

Raport Światowej Organizacji Zdrowia z 1984 roku sugerował, że nawet 30% nowych i zmodernizowanych budynków może mieć problemy z jakością powietrza wewnętrznego wystarczające do wywołania objawów zdrowotnych. Nieodpowiednia wentylacja budynków jest najczęstszą przyczyną; pojawienie się SBS w połowie lat 70. często przypisywano zmniejszonym standardom wentylacji budynków komercyjnych w celu zwiększenia efektywności energetycznej, po arabskim embargu na ropę naftową z 1973 roku.37

Na początku kryzysu energetycznego w latach 70. budowniczowie i właściciele budynków podjęli kroki w celu zmniejszenia zużycia energii w budynkach biurowych, co prowadziło do tworzenia szczelnych budynków z ograniczoną wymianą powietrza z otoczeniem.3839

Według badacza Strausa, związek między SBS a zmianami w projektowaniu budynków jest wyraźny. Nowoczesne, energooszczędne budynki zależne od systemów HVAC zamiast otwartych okien dla cyrkulacji powietrza są bardziej narażone na problemy związane z jakością powietrza wewnętrznego.4041

Jak podkreślono w raporcie z DC8C82BB42, w przyszłości konieczne będzie uwzględnienie wpływu oszczędzania energii i zmian klimatycznych na jakość środowiska wewnętrznego budynków.42

ozone-interakcje”>Złożone interakcje czynników powodujących SBS

Zespół chorego budynku jest wynikiem złożonych interakcji między wieloma czynnikami. Rzadko kiedy pojedynczy czynnik jest odpowiedzialny za wszystkie objawy.4344

Czynniki powodujące SBS mogą działać w kombinacji i narastać do punktu, w którym ludzie w danym obszarze zaczynają odczuwać fizyczne dolegliwości. Główną przyczyną SBS jest prawdopodobnie jakość i efektywność wewnętrznego systemu wentylacji, ale inne czynniki również odgrywają istotną rolę.45

Zanieczyszczenia wewnętrzne mogą wpływać na jakość powietrza samodzielnie lub w połączeniu ze sobą. Ze względu na ogromną liczbę zmiennych, zespół chorego budynku może być niezwykle trudny do zdiagnozowania.46

Jest oczywiste, że istnieje wiele kombinacji źródeł zanieczyszczeń, a ponadto źródła te mogą nie być niezależne. Potencjalny zakres zanieczyszczeń w środowisku biurowym jest ogromny, co dodatkowo utrudnia identyfikację konkretnej przyczyny SBS.15

Wszystkie te czynniki mogą działać w połączeniu i mogą uzupełniać inne problemy, takie jak nieodpowiednia temperatura, wilgotność lub oświetlenie. Jednak nawet po dokładnym zbadaniu budynku konkretne przyczyny dolegliwości mogą pozostać nieznane.47

Jednym z powodów braku dokładnej przyczyny lub lekarstwa na SBS jest to, że większość badań SBS analizuje tylko część problemu. Gdyby problem był czysto fizyczny, znaleziono by rozwiązanie, które wyeliminowałoby problem, dlatego logiczne jest, aby wywnioskować, że SBS nie jest wyłącznie problemem fizycznym.6

Konsekwencje i wnioski

Zespół chorego budynku stanowi poważne wyzwanie dla zdrowia publicznego i środowiska pracy. Objawy SBS mogą prowadzić do znaczącej utraty produktywności, zwiększonej absencji chorobowej i pogorszenia jakości życia osób dotkniętych tym problemem.736

Szacuje się, że objawy związane z zespołem chorego budynku kosztują brytyjską gospodarkę około 24,6 miliona funtów rocznie w postaci utraconych dni pracy. W Stanach Zjednoczonych ponad połowa Amerykanów spędza czas pracy w biurach lub środowiskach podobnych do biur, a do 60% pracowników biurowych zgłasza co najmniej jeden problem zdrowotny przypisywany ich miejscu pracy.748

Chociaż zespół chorego budynku nadal stanowi wyzwanie diagnostyczne i terapeutyczne, rosnące zrozumienie jego złożonych przyczyn pozwala na opracowanie bardziej efektywnych strategii prewencyjnych i interwencyjnych. Podejście holistyczne, uwzględniające zarówno czynniki fizyczne, jak i psychospołeczne, wydaje się być najbardziej obiecującą metodą radzenia sobie z tym problemem.42

Jak podkreślono w badaniach, koszt zmniejszonej produktywności, zastępowania pracowników i postępowań sądowych sprawia, że ​​zapobieganie jest bezsprzecznie lepsze niż leczenie. Dlatego też priorytetem powinno być projektowanie i utrzymywanie budynków w sposób minimalizujący ryzyko SBS oraz edukacja użytkowników budynków w zakresie czynników ryzyka i strategii prewencyjnych.15

Należy również zwrócić większą uwagę na środowisko wewnętrzne w szkołach, przedszkolach, szpitalach i domach opieki dla osób starszych. Poprawa środowiska domowego może być najbardziej opłacalnym sposobem zmniejszenia obciążenia związanego z ekspozycją wewnętrzną. Nie należy również zaniedbywać związku między zanieczyszczeniem powietrza wewnętrznego i zewnętrznego.42

  • #1 The sick building syndrome
    https://pmc.ncbi.nlm.nih.gov/articles/PMC2796751/
    The sick building syndrome comprises of various nonspecific symptoms that occur in the occupants of a building. This feeling of ill health increases sickness absenteeism and causes a decrease in productivity of the workers. As this syndrome is increasingly becoming a major occupational hazard, the cause, management and prevention of this condition have been discussed in this article. […] The sick building syndrome (SBS) is used to describe a situation in which the occupants of a building experience acute health- or comfort-related effects that seem to be linked directly to the time spent in the building. No specific illness or cause can be identified. The complainants may be localized in a particular room or zone or may be widespread throughout the building. […] The cause of the symptoms is not known. It reduces work efficiency and increases absenteeism. Most of the complainants report relief soon after leaving the building, although lingering effects of neurotoxins can occur.
  • #2 Sick Building Syndrome: Symptoms, Causes, Tests & Prevention
    https://www.emedicinehealth.com/sick_building_syndrome/article_em.htm
    Sick building syndrome is a condition that occurs when a number of a building’s occupants have a constellation of nonspecific symptoms without a specific identifiable cause, including nausea; irritation of the eyes, nose and throat; mental fatigue; headaches; skin irritation; and dizziness. […] Sick building syndrome should not be confused with building-related diseases, which have a specific identifiable cause of the symptoms. […] There are many theories as to what causes sick building syndrome. Commonly cited causes are inadequate ventilation, chemical contaminants from indoor sources, and chemical contaminants from outdoor sources. […] Inadequate ventilation is one the most often cited reasons. […] Common chemical contaminants inside the building are found in paint, adhesives, carpeting, cleaning agents, and upholstered furniture. […] Common chemical contaminants from outside of the building can include exhaust from motor vehicles and other industrial plants in the area.

    A person may experience acute symptoms upon entering a building. However, the symptoms may disappear when the person leaves the building. These short-term symptoms are related to sick building syndrome (SBS). […] Sick building syndrome is used as a term to refer to symptoms of acute health and/or comfort effects for which no specific cause can be found but that can be attributed to time spent in a particular building. […] The concept of SBS was defined by the World Health Organization (WHO) in 1983 as: 'a collection of nonspecific symptoms including eyes, nose and throat irritation, mental fatigue, headaches, nausea, dizziness and skin irritation, that seem to be associated with occupancy of certain workplaces’. […] SBS and BRI are associated with acute or immediate health problems. […] Symptoms and illnesses related or attributed to indoor environments are common. […] Building-related illnesses with known causes are much less common than sick building syndrome, in which there is no identifiable cause for nonspecific symptoms.
  • #4 Sick building syndrome (SBS) | EBSCO Research Starters
    https://www.ebsco.com/research-starters/construction-and-building/sick-building-syndrome-sbs
    SBS is generally distinguished from building-related illnesses that are caused by to specific indoor contaminants that can be definitively diagnosed. […] Public health officials have advised that seemingly minor complaints by office workers should be accepted as serious, and, if SBS is suspected, investigation should begin to determine if the buildings indoor air quality is acceptable and to identify the cause of the suspected outbreak.

    The symptoms characterising SBS are commonplace in the general population, but it is the pattern of their expression that points to the diagnosis of SBS. […] Goldman (1996) also believes that the symptoms characterising SBS, first noted in the 1950s, appeared to be correlated with the development of post-war, energy efficient, airtight buildings, at a time when the architects’ main brief was to keep costs low. […] It is important to understand that a consideration of the physical environment should also be given attention. […] The general nature of the symptoms means that they will be reported to some degree in all buildings. […] It is found, however, that the level of symptoms varies between buildings, and buildings where symptom rates were high do tend to have a number of common features as mentioned previously (Goldman, 1996).

    https://link.springer.com/article/10.1057/rlp.2008.20
    One reason for the lack of an accurate cause or cure for SBS is that the majority of investigations into SBS only look at part of the problem. […] If the problem were purely physical, a solution would have been found to eradicate the problem, so it is logical to reason that SBS is not purely a physical problem. […] There is evidence that, although SBS does not cause serious damage to health, it does result in potentially problematic consequences.

    Sick Building Syndrome (SBS) symptoms are thought to cost the British economy around 24.6 million annually in lost working days. […] Sick Building Syndrome (SBS) is a condition where the occupants of a building or other enclosed indoor environment begin to experience health or comfort-related symptoms that disappear upon leaving the space. […] While the exact underlying causes of SBS are difficult to identify, research suggests that it’s most likely caused by a combination of factors related to the health of your building. […] Probable causes include: poor ventilation with an insufficient volume of air change, low humidity, high temperatures or constant changes in temperature throughout the day, airborne pollutants, such as dust, carpet fibres or fungal spores, poor standards of cleanliness in the working environment, poor lighting that causes glare or flicker on visual display units. […] These sources could all potentially contribute to poor air quality. If several of these factors are at work at the same time, there’s undoubtedly going to be a negative impact on both the health and productivity of your employees.

    http://publichealth.lacounty.gov/eh/safety/sick-building-syndrome.htm
    Most of the time, however, no specific cause for the symptoms can be found in the building. Some experts speculate that, in many of these cases, poor indoor air quality may play a role. […] A number of factors can contribute to poor indoor air quality in an office setting, inadequate ventilation being among the most important. Poor ventilation clearly compromises the health of a building’s occupants. […] The occupants of buildings and their work activities can also impact indoor air quality. Environmental tobacco smoke contains a variety of toxic air contaminants and cleaning agents emit volatile organic compounds like toluene and benzene. […] Analyzing air samples to determine air quality seems like a logical way to evaluate „sick building” complaints, but it seldom provides useful information.

    The Environmental Protection Agency defines Sick Building Syndrome (SBS) as situations in which building occupants experience acute health and comfort effects that appear to be linked to time spent in a building, but no specific illness or cause can be identified. […] Sick Building Syndrome can stem from a number of various causes, but there are four main groups. Studies done by The National Institute for Occupational Safety and Health (NIOSH) measured how often these sources contribute to poor air quality indoors. […] Inadequate ventilation (52% of cases) This is often an HVAC issue, as the system fails to distribute air properly throughout the building. […] Chemical toxins originating from indoors (16% of cases) Indoor sources are actually to blame for a large majority of the air pollution in a building. Adhesives, manufactured wood, and even emissions from equipment such as copy machines can contain dangerous toxins including formaldehyde.

    https://pmc.ncbi.nlm.nih.gov/articles/PMC2796751/
    The following are some of the factors that might be primarily responsible for SBS: […] Chemical contaminants […] From outdoor sources: Contaminants from outside like pollutants from motor vehicle exhaust, plumbing vents and building exhausts (bathrooms and kitchens) can enter the building through poorly located air intake vents, windows and other openings. […] From indoor sources: The most common contaminant of indoor air includes the volatile organic compounds (VOC). The main sources of VOC are adhesives, upholstery, carpeting, copy machines, manufactured wood products, pesticides, cleaning agents, etc. […] Biological contaminants […] The biological contaminants include pollen, bacteria, viruses, fungus, molds, etc. […] Inadequate ventilation […] The ventilation was reduced to 5 cfm/person. This reduced ventilation rate was found to be inadequate to maintain the health and comfort of building occupants.

    https://www.setra.com/blog/what-causes-sick-building-syndrome
    After understanding the basis of sick building syndrome, recognizing the root causes for the syndrome is the next step for prevention or treatment. By properly identifying the root causes, suitable countermeasures can be constructed. Causes for sick building syndrome can be classified into three categories: […] Carbon monoxide, carbon dioxide, or other organic compounds can be emitted from heating products such as kerosene, gas space heaters, and stoves […] Insufficient outside air, poor filtration of internal air, and contaminated duct work […] ASHRAE recommends a minimum of 15 ft3/min (CFM) of outdoor air per person, and 20 CFM per person in office spaces […] If an intake air vent is poorly located, supply air could come from restrooms or kitchen exhausts, plumbing vented air, dumpster odors and from nearby parking garages or traffic

    https://en.wikibooks.org/wiki/Lentis/Sick_Building_Syndrome
    Inadequate ventilation rates increases the likelihood of SBS. Inadequate ventilation can be attributed to: lack of compliance with applicable codes and standards, such as those published by ASHRAE; installation or maintenance problems; and not accounting for ventilation during remodeling or space use changes. […] Biological contaminants include pollen, bacteria, viruses, and mold, and can cause fever, chills, cough, chest tightness, muscle aches, and allergic reactions. […] Indoor air pollution can come from sources such as adhesives, carpeting, upholstery, copy machines and cleaning products. These sources emit volatile organic compounds (VOCs) which can produce acute reactions in people even at low or moderate levels. […] Outdoor air pollutants such as vehicle exhaust, combustion byproducts, or tobacco smoke enter buildings through air intake vents, windows or other openings. These pollutants then become a form of indoor air pollution and can exacerbate SBS symptoms.

    The term „sick building syndrome” (SBS) is used to describe situations in which building occupants experience acute health and comfort effects that appear to be linked to time spent in a building, but no specific illness or cause can be identified. […] The following have been cited as causes of or contributing factors to sick building syndrome: […] Inadequate ventilation, which may also occur if heating, ventilating, and air conditioning (HVAC) systems do not effectively distribute air to people in the building, is thought to be an important factor in SBS. […] Most indoor air pollution comes from sources inside the building. […] The outdoor air that enters a building can be a source of indoor air pollution. […] Bacteria, molds, pollen, and viruses are types of biological contaminants.
  • #14 The sick building syndrome
    https://pmc.ncbi.nlm.nih.gov/articles/PMC2796751/
    Psychological factors […] Excessive work stress or dissatisfaction, poor interpersonal relationships and poor communication are often seen to be associated with SBS. […] The symptoms of SBS are commonly seen in people with clerical jobs than in people with managerial jobs because professionals or managers have better working conditions. The symptoms are more common in females than in males probably because more females are in secretarial jobs, they are more aware of their health or a lesser dose of pollutants is required to manifest the effects. The symptoms are more common in air-conditioned buildings than in naturally ventilated buildings and are more common in a public sector building than in a private sector building.

    https://link.springer.com/article/10.1057/rlp.2008.20
    Therefore, it is clear to see that the cost of reduced productivity, replacement staff and litigation make prevention unarguably better than cure. […] Evidence for a correlation between ventilation rate and SBS symptoms is at best patchy. […] Generally, air-conditioned buildings have higher rates of symptoms than naturally ventilated buildings. […] It is clear that there are many combinations of sources of pollutants, and in addition, the sources may not be independent. […] The potential range of pollutants in the office environment is therefore enormous. […] Job stress and dissatisfaction are probably more important causes of symptoms than physical and chemical factors in the indoor environment. […] The prevalence of symptoms appears to be highest among clerical staff, with their more routine work, than among professional staff.

    Sick Build Syndrome (SBS) is a condition in which a person suffers from adverse health effects or becomes infected with chronic disease from the building in which they work or reside. […] However, it should be noted that no specific illness or cause of it can be identified. […] Sick building syndrome has no known cause, however, known causes of illness such as lead poisoning, formaldehyde fumes, and many others have been associated with individual buildings.
