Abstract:
Dampness, which is frequently caused by water ingress from heavy rainfall, building usage, maintenance practice, condensation, or insufficient ventilation, can manifest in a variety of ways, ranging from visible damp patches on walls to less visible but equally insidious effects below the surface. Understanding the factors contributing to dampness is critical for architects, builders, and maintenance professionals looking to protect structures from damaging effects. This paper reports on a finding of unwanted dampness in university facility buildings. The primary goal is to highlight significant issues and propose potential solutions, as well as to raise building owners' awareness of building condition surveys and their relationship to building maintenance management. The condition assessment will bring a wide range of non-destructive equipment to four facility buildings of university. This paper contributed to a better understanding of dampness factors in building structures. It also looks at ways to improve the building's maintenance strategies.

Abstract:
Dampness is a continuing cause of distress to building occupants. The effects of dampness have become a major problem when it invades into building. It is also a possible source of or a contributor to illness and it encourages deterioration in the fabric of the building. With an emphasis on existing buildings and some coverage of the design of new buildings, the objectives of this research are to investigate the causes of dampness during and after the construction of buildings, identify the effects of dampness on the building and its occupants and offer recommendations on the above mention issues. The level of dampness causes and effects differ across geographic areas, climates, and building types. A descriptive survey technique was used to gather information about rising damp in the municipality which includes questionnaires, interviews, and personal observations. According to the findings, the condition resulting in rising dampness to the base of walls was the lack of incorporation of damp-proof courses during construction. Also, the problem of rising dampness reoccurs shortly after treatment because of the application of the wrong treatment method as well as the absence of damp treatment specialists. The effects of rising dampness led to damage to plaster work, crumbling of masonry, peeling of paintwork, efflorescence on wall surfaces, uncomfortable, unattractive rooms, and the cost of painting a room or building yearly. From the findings, it is recommended that damp proof courses (DPCs) should be placed through the full thickness of the base of walls below floor level to form an impervious layer that keeps rising damp out of the buildings.

Abstract:
Studies have established that comfort level, emotional balance, wellbeing and productivity are linked to the functionality of buildings. Functional buildings, however, require less energy for sustainability purposes. To achieve these advantages, there is a need to seek improvement in the existing stock of buildings or procure newer ones. Seeking improvement connotes reducing building defects/failures and improving occupant-comfort. Dampness plagues both new and old buildings and contributes more than 50% of building envelopes’ defects, discomfort, or failure. This study, therefore, examined dampness in halls of residence in selected tertiary institutions in Lagos metropolis, using the University of Lagos as a case study. The objectives were to evaluate the incidence and causes of dampness in the halls of residence in the institution. As a preliminary assessment of dampness evaluation in halls of residence, the institution used is the University of Lagos, as a case study. This is selected based on its location and proximity. The study population consists of undergraduate and postgraduate halls of residence while the sample frame is undergraduate male hostels. The four undergraduate male hostels are taken as the sample size, using the census as the sampling technique. From the four male halls of residence; eighty rooms and two maintenance staff per block were selected using a purposive sampling technique. Analyses were done using mean, percentage, and relative importance index. The results revealed the presence of the four types of dampness, with dampness from leaking pipes as the most prevalent. The dampness originated from a combination of a host of factors, with those emanating from the negligence of maintenance culture and lack of materials/workmanship consideration as the top two causes. The study concluded that symptoms of the four dampness types are in existence in the four sampled halls of residence and the factors causing dampness are many and allen compassing, but if the issue of maintenance and materials/workmanship are professionally handled, dampness will reduce, hence better comfort and building longevity can be guaranteed. The symptoms of buildings deterioration and defects can be minimised with ease of maintenance and through the use of professionals that are apt in the knowledge of materials and components inter-relationship. The study emphasised the significance of a healthy building and recommended that such should be procured with all hands-on deck and handled by the professionals in the built environment.

Abstract:
Building dampness, arising from excessive moisture accumulation within structures, stands as a pervasive concern impacting buildings and their inhabitants globally. This research tried to unravel the root cause of building dampness and understand its far-reaching implications, encompassing structural integrity and health implications. The research collected data from the site and an in-depth analysis was conducted to ascertain the moisture level and structural integrity of buildings in the selected community. The research results and findings indicate that builders mostly do not apply the appropriate building principles nor seek technical supervision in raising structures. The research also sought to contribute to a deeper understanding of this prevalent issue of dampness in building structures and provided effective mitigation strategies to create healthier and sustainable built environments.

Abstract:
PurposeDampness in buildings affects the health of occupants, structural stability and energy efficiency of buildings. Solutions to managing dampness focus on promoting the use of damp-proof construction materials, enhancing methods to avoid the introduction of moisture during construction and creating the awareness on the health effect of dampness. These solutions are incomplete without the identification of behaviours that occupants require to manage dampness. Given that dampness is characterised by the availability of a source, a route for the moisture to travel and driving force for moisture movement, the occupants can be said to play a significant role in contributing to dampness. The paper aims to discuss these issues.Design/methodology/approachAs a result, this study seeks to examine the behaviours of occupants manifested to manage dampness in residential buildings. To achieve the aim, a qualitative research method was employed, under which interviews were carried out. Occupants in households in the northern and southern parts of England were interviewed to identify the actions, attitudes and beliefs in managing dampness.FindingsThe findings revealed actions such as aeration and the use of anti-damp sprays. From the findings, dampness instilled attitudes such as anger, moodiness and unhappiness. In addition, dampness instilled cleaning habits in occupants due to the lack of comfort moulds create and the awareness of its health impact.Research limitations/implicationsThis research also contributes to existing debates on dampness reduction specifically in residential buildings.Originality/valueThe identification of these behaviours creates the awareness for occupants on their roles in managing dampness and how dampness affects their behaviours in addition to the health impact.

Abstract:
This study investigated the association of building characteristics and occupant behaviours with building dampness indicators. Data were from a cross-sectional study in urban Tianjin and rural Cangzhou, China, from 2013 to 2014. We studied two fundamental types of Chinese dwellings: bungalows typical of rural locales and apartments in low- and high-rise buildings typical of urban settings. Occupants of bungalows reported more dampness indicators than apartment dwellers. Risk factors for one or more dampness indicators included natural ventilation without fans, older dwellings and coal stove or Kang heating system (a brick bed installed in the bedroom for heating and sleeping). All these factors were typical of bungalows, which generally used older building technologies including non-insulated external walls, wooden frame windows, electric fans for cooling and no exhaust fan ventilation. Occupant behaviours that decreased the risk for dampness indicators included frequent window opening and daily cleaning, regardless of the type of dwelling. Indoor dampness was highly correlated with mouldy and humid odour, and paradoxically (although not a new finding) with the perception of air dryness.

Abstract:
A subset of adult-onset asthma patients attribute their symptoms to damp and moldy buildings. Symptoms of idiopathic environmental intolerance (IEI) may resemble asthma and these two entities overlap. We aimed to evaluate if a distinct clinical subtype of asthma related to damp and moldy buildings can be identified, to unravel its corresponding pathomechanistic gene signatures, and to investigate potential molecular similarities with IEI. Fifty female adult-onset asthma patients were categorized based on exposure to building dampness and molds during disease initiation. IEI patients (n = 17) and healthy subjects (n = 21) were also included yielding 88 study subjects. IEI was scored with the Quick Environmental Exposure and Sensitivity Inventory (QEESI) questionnaire. Inflammation was evaluated by blood cell type profiling and cytokine measurements. Disease mechanisms were investigated via gene set variation analysis of RNA from nasal biopsies and peripheral blood mononuclear cells. Nasal biopsy gene expression and plasma cytokine profiles suggested airway and systemic inflammation in asthma without exposure to dampness (AND). Similar evidence of inflammation was absent in patients with dampness-and-mold-related asthma (AAD). Gene expression signatures revealed a greater degree of similarity between IEI and dampness-related asthma than between IEI patients and asthma not associated to dampness and mold. Blood cell transcriptome of IEI subjects showed strong suppression of immune cell activation, migration, and movement. QEESI scores correlated to blood cell gene expression of all study subjects. Transcriptomic analysis revealed clear pathomechanisms for AND but not AAD patients. Furthermore, we found a distinct molecular pathological profile in nasal and blood immune cells of IEI subjects, including several differentially expressed genes that were also identified in AAD samples, suggesting IEI-type mechanisms.

Abstract:
Purpose The paper aims to present an innovative solution for evaluation study of the dampness level of walls and historical buildings. Design/methodology/approach Electrical tomography enables one to obtain a distribution pattern of wall dampness. The application of modern tomographic techniques in conjunction with topological algorithms will allow one to perform very accurate spatial assessment of the dampness levels of buildings. The proposed application uses the total variation, Gauss–Newton and level set method to solve the inverse problem in electrical tomography. Findings Research shows that electrical tomography can provide effective results in damp buildings. This method can provide 2D/3D moisture distribution pattern. Research limitations/implications The impact of this technique will be limited to inspection of the facility after floods or assessment of historical buildings. Practical implications The presented method could eventually lead to a much more effective evaluation of moisture in the walls. Social implications The solution has commercial potential and could result in more cost-effective monitoring of historical buildings, which have an economic impact on society. Originality/value The authors propose a system for imaging spatial moistness of walls and historic buildings based on electrical tomography and consisting of a measuring device, sensors and image reconstruction algorithms.

Abstract:
Indoor dampness and mold are prevalent, and the exposure has been associated with various illnesses such as the exacerbation of existing asthma, asthma development, current asthma, ever-diagnosed asthma, bronchitis, respiratory infection, allergic rhinitis, dyspnea, wheezing, cough, upper respiratory symptoms, and eczema. However, assessing exposures or environments in damp and moldy buildings/rooms, especially by collecting and analyzing environmental samples for microbial agents, is complicated. Nonetheless, observational assessment (visual and olfactory inspection) has been demonstrated as an effective method for evaluating indoor dampness and mold. The National Institute for Occupational Safety and Health developed an observational assessment method called the Dampness and Mold Assessment Tool (DMAT). The DMAT uses a semi-quantitative approach to score the level of dampness and mold-related damage (mold odor, water damage/stains, visible mold, and wetness/dampness) by intensity or size for each of the room components (ceiling, walls, windows, floor, furnishings, ventilation system, pipes, and supplies and materials). Total or average room scores and factor-or component-specific scores can be calculated for data analysis. Because the DMAT uses a semi-quantitative scoring method, it better differentiates the level of damage compared to the binary (presence or absence of damage) approach. Thus, our DMAT provides useful information on identifying dampness and mold, tracking and comparing past and present damage by the scores, and prioritizing remediation to avoid potential adverse health effects in occupants. This protocol-type article describes the DMAT and demonstrates how to apply it to effectively manage indoor dampness and mold-related damage.

Abstract:
Unblanced forced-air heating systems create a situation that may be detrimental to the building envelope. These systems create an air pressure differential, which acts as a moisture transport mechanism, which has the potential to carry moisture, through the smallest of openings in the building envelope. Once this warm air enters the wall cavity it comes into contact with the unheated surfaces of the components making up the building envelope, which are below dew point during the heating months. As this moisture-laden air reaches its dew point, condensation occurs.

Abstract:
L’isolation thermique par l’extérieure (ITE) constitue une solution technique intéressante pour améliorer les performances énergétiques du secteur du bâtiment. Cependant, l’ITE peut venir modifier l’équilibre hygrothermique de l’enveloppe et affecter sa durabilité, notamment au regard de l’humidité. Dans ce contexte, un premier travail a consisté à étudier en laboratoire le comportement hygrothermique de trois systèmes d’ITE rapportés sur une paroi en parpaing : un système ETICS (PSE sous enduit mis en œuvre par voie humide) et deux systèmes sous bardage (mis en œuvre par voie sèche), dont un incluant des matériaux biosourcés (laine de bois et ouate de cellulose). Des expériences en enceinte biclimatique, combinées à des simulations numériques des transferts couplés de chaleur et de masse, ont permis d’appréhender le comportement hygrothermique de ces parois rénovées à différents stades : lors de la pose des solutions d’ITE, en usage « normal » et dans des conditions conduisant à des risques de condensation. Les résultats du système ETICS montrent le rôle important de la colle et la difficulté à appréhender numériquement son comportement. Les résultats des systèmes sous bardage soulignent l’intérêt d’utiliser des matériaux biosourcés dans des conditions à risques, mais également la sensibilité des simulations numériques aux propriétés hydriques des matériaux hygroscopiques. Un second travail portant sur l’analyse in situ d’un système d’ITE sous bardage a souligné l’absence de risques majeurs liés à l’humidité durant les deux années étudiées. Par ailleurs, la comparaison simulation/expérience a mis en évidence le rôle important joué par la lame d’air ventilée
External thermal insulation (ETI) is an interesting technical solution for improving the energy performance of the building sector. However, ETI may change the hygrothermal balance of the envelope and affect its durability, especially with regard to moisture. With this in mind, a first work consisted in studying the hygrothermal behavior of three systems of ETI set on a hollow concrete block wall in the laboratory: an ETICS system (wet process) and two systems under cladding (dry process), with one of them composed with bio-based materials (wood wool and cellulose wadding). Experiments in a bi-climatic enclosure, combined with numerical simulations of coupled heat and mass transfers, made it possible to apprehend the hygrothermal behavior of these renovated walls at different stages: during the installation of ETI solutions, in "normal" use and under conditions leading to risks of condensation. The results of the ETICS system show the important role of the glue and the difficulty to understand numerically its behavior. The results of the cladding systems underline the interest of using bio-based materials under hazardous conditions, but also the sensitivity of numerical simulations to the hydric properties of hygroscopic materials. A second study on the in situ analysis of a cladding ETI system highlighted the absence of major risks related to humidity during the two years studied. In addition, the simulation / experiment comparison highlighted the important role played by the ventilated air

Abstract:

The air gap method is a modification of the common way of building indoor walls and floors. The aim of the method is to make a construction, less fragile to water damage, with air gaps where moisture can be removed with a thermally driven air flow, caused by a heating cable. The thesis includes a number of experimental studies of this method.

Temperature and convective air flow in a vertical air gap was studied and it was noted how air flow increased with raised power of the heating cable. The air flow for one meter of wall varied between 50 m3/day (13 air changes per hour) and 140 m3/day (36 air changes per hour). The lower value was caused by a temperature difference in the range 0.2-0.3 oC. Without heating no air flow was found.

In studies of moisture and RH in wet “slab on ground” constructions, it was noted how the slab in the room with the air gap method dried to a much higher extent than the slab in the room built in an ordinary way. It was also noted that moisture was transported from the air gap in the floor and up through the air gap in the wall. In the room with the air gap construction, the RH values beneath the floor was at a lower level (and below 75 % RH) than the RH values beneath the floor of conventional construction. Mould does not grow below 75 % RH.

In the study of a flooded intermediate floor it was noted how the thermally driven convective air flow evidently speeded up drying of the construction. Mould growth was only noted in the case where the heating cables were turned off.


Spaltmetoden är en modifiering av det reguljära sättet av att bygga innerväggar och bjälklag. Syftet med metoden är att skapa en byggnadskonstruktion som är mindre skör med avseende på fuktskador. Detta görs med spalter där fukt kan avlägsnas genom ett termiskt drivet luftflöde som orsakas av en värmekabel. Denna avhandling innehåller ett antal experimentella studier på metoden. Spaltmetoden har studerats med avseende på 1. Samband mellan temperatur och luftflöde, 2. Uttorkning och RF nivåer i golvkonstruktioner samt 3. Översvämning av ett mellanbjälklag

1. Samband mellan temperatur och luftflöde

Temperatur och konvektivt luftflöde har studerats i en vertikal spalt och resultatet visar att luftflödet ökar med ökad effekt hos värmekabeln. Luftflödet i en vägg med en meters bredd varierade mellan 50 kubikmeter/dag (13 luftväxlingar per timme) och 140 kubikmeter/dag (36 luftväxlingar per timme). Det lägre flödet orsakades av en temperaturskillnad på 0,2-0,3 oC mellan luftspalt och rum. När värmekabeln var avstängd så registrerades inget luftflöde.

2. Uttorkning och RF nivåer i golvkonstruktioner ovan betongplatta

Detta experiment visade att fukt har transporterats från spalten i golvet genom spalten i väggen ut i rumsluften. I spaltkonstruktion var RF inuti golvkonstruktionen lägre (och understeg 75 % RF), jämfört med den konventionella konstruktionen, (mögel växer inte under 75 % RF). Det har också registrerats att betongplattan som hörde till spaltmetoden torkade ut snabbare än betongplattan som var inbyggd i ett gängse rum.

3. Översvämning av ett mellanbjälklag

I studien där ett mellanbjälklag blev översvämmat noterades att spaltmetoden förkortade torktiden från 21 dagar till 13 vid den fuktigaste mätpunkten. Mögelväxt noterades endast då värmekabeln hade varit frånslagen.

Abstract:
Several studies have showed that the occupants of damp or mouldy buildings have an increased risk of respiratory symptoms, respiratory infections and exacerbation of asthma. However, information on the school environment in this context is limited and hence more studies are needed. These dampness-related health effects may be associated with different indoor pollutants, but the causal mechanisms and aetiological agents are still largely unknown. Included in the HITEA project, this thesis aims to assess the occurrence of moisture problems in school buildings in three European countries from different climatic regions and to study the respiratory health effects associated with dampness and mould in schoolchildren. A questionnaire survey and school inspection visits were conducted to assess moisture damage, dampness problems and other indoor air quality issues in primary schools in the three countries under study. Following, we carried out an extensive questionnaire survey on respiratory health of pupils aged 6-12 years, in at least eight moisture-damaged and eight non-damaged schools per country. Our results showed that moisture problems were relatively common in schools in all three climatic regions across Europe. Spanish school buildings had the highest prevalence of these problems, followed by The Netherlands and Finland. Moreover dampness and mould in schools were associated with adverse respiratory symptoms in pupils, especially in Finland. In conclusion, Dampness and mould in schools may have respiratory adverse health effects in children. Finnish school children seem to be at higher risk, possibly due to quantitative and/or qualitative differences in exposure, due to variations in climate and building characteristics. Thus, prevention and remediation measures should be considered to reduce dampness and mould problems in school buildings to protect pupils’ health.
Diversos estudios han observado que los ocupantes de edificios con problemas de humedad o moho tienen más riesgo de padecer síntomas respiratorios, infecciones respiratorias y exacerbación asmática. Aún así, la información sobre el entorno escolar en este contexto es limitada y por ello más estudios son necesarios. Los efectos en la salud relacionados con la humedad en los edificios pueden estar asociados con diferentes contaminantes interiores, pero los mecanismos causales y los factores etiológicos siguen siendo desconocidos. Incluida en el proyecto HITEA, esta tesis pretende evaluar cualitativa y cuantitativamente la prevalencia de edificios escolares con problemas de humedad en tres países europeos de tres regiones climáticas distintas y estudiar los efectos en la salud asociados a la humedad y el moho en sus alumnos. Se realizaron cuestionarios e inspecciones en los colegios de los tres países a estudio, para evaluar los posibles daños y problemas relacionados con la humedad y otros factores asociados con la calidad del aire interior. A continuación, se llevó a cabo un amplio cuestionario sobre salud respiratoria en los alumnos de entre 6 y 12 años, en al menos 8 escuelas con problemas de humedad y 8 escuelas sin problemas. Los resultados mostraron que los problemas de humedad en los edificios escolares eran relativamente comunes en las 3 regiones climáticas europeas. Las escuelas españolas presentaron una mayor prevalencia de problemas de humedad, seguidas de Holanda y Finlandia. Además, los problemas de humedad y moho en los edificios escolares se asociaron con síntomas respiratorios adversos en los alumnos, especialmente en Finlandia. En conclusión, los problemas de humedad y moho en los edificios escolares podrían tener efectos adversos en la salud respiratoria de los niños. Los alumnos finlandeses parecen tener más riesgo, posiblemente debido a diferencias cuantitativas y/o cualitativas en la exposición. Esto podría estar relacionado con las diferentes características de los edificios y con la variabilidad climática. Así pues, para proteger la salud de los alumnos se deberían considerar diversas medidas de prevención y reparación de los problemas de humedad y moho en los edificios escolares.

Abstract:
Day care centers and schools are important environments for children, but few epidemiological studies exist from these environments. Mould, dampness, fungal DNA and allergens levels in these environments and respiratory health effects in school children were investigated in this thesis. In the day care centers studies, Allergen Avoidance Day care Centers (AADCs) and Ordinary Day care Centers were included. One third of the Swedish day care centers had a history of dampness or mould growth. Total fungal DNA levels were positively associated with risk construction buildings, reported dampness/moulds, rotating heat exchangers, linoleum floors and allergens (cat, dog, horse allergen) levels. The two school studies included secondary schools in Johor Bahru, Malaysia and elementary schools from five European countries (Italy, Denmark, Sweden, Norway, and France) (HESE-study). In Malaysia, 13 % of the pupils reported doctor-diagnosed asthma but only 4 % had asthma medication. The prevalence of wheeze in the last 12 months was 10 % in Malaysia and 13 % in the HESE-study. Cough and rhinitis were common among children in the HESE-study. There were associations between fungal DNA and reported dampness or mould growth. Fungal DNA levels and viable mould (VM) concentration in the classrooms were associated with respiratory symptoms (wheeze, rhinitis, cough, daytime breathlessness) in school children. In the HESE-study, associations were found between total fungal DNA, Aspergillus/Penicillium DNA and respiratory symptoms among children. Moreover, Aspergillus versicolor DNA and Streptomyces DNA were associated with respiratory symptoms in Malaysia and the HESE-study, as well as reduced lung function [forced vitality capacity (FVC) and forced expiratory volume in 1 second (FEV1)] among children in the HESE-study. In conclusion, fungal DNA and pet allergens were common in day care centers and schools and respiratory symptoms in school children were common. The associations between VM concentration and fungal DNA levels in the schools and respiratory health effects in school children indicated a need for improvement of these environments. Moreover, risk constructions should be avoided and buildings should be maintained to avoid dampness and microbial growth. Health relevance of microbial exposure and biodiversity needs to be further studied using molecular methods.

Abstract:
The study aimed to identify deterioration problems, repair and conservation needs of andesites on the walls of the Ankara Castle. Decay forms of walls were documented by visual examination. Samples taken from the surface of the weathered andesites were examined for their basic physical, mechanical compositional and minerological properties. The bulk density and total porosity were determined as basic physical properties. The mechanical properties were expressed as ultrasonic velocity and modulus of elasticity (Emod). Compositional and mineralogical properties were determined by optical microscopy and XRD analyses. Soluble salt content of the andesite samples was determined by spot tests of anions and electrical conductivity measurements. Findings were evaluated in terms of the long-term weathering behaviour of andesites under the effect of the prevailing climate, air pollution problems of Ankara, dampness problems of the structure, previous repairs with incompatible cement mortars. The surfaces of Ankara Castle andesite blocks were heavily weathered. The results were compared with the physical and mechanical properties of fresh andesites from Gö
lbaSi-Ankara quarry. The surface of the andesite blocks at the Ankara Castle, had low bulk density and high porosity, low ultrasonic velocity and low Emod values. Thin section and XRD analyses supported those results by revealing the presence of physical and chemical weathering on feldspars and other main minerals of andesite, as well as the presence of amorphous minerals at the surface.
