Symptoms Of Sick Building Syndrome Construction Essay

Symptoms Of Sick Building Syndrome Construction EssaySBS stands for Sick Building Syndrome. It covers a mixture of symptoms thought to be gene set upd when a savant at school spends time in a particular mental synthesis. The symptoms ladder from itchy eyes, skin rashes, and nasal allergy symptoms, to more complicated symptoms such as fatigue, pains, and sensitivity to odours. On the other(a) hand, it whitethorn be curb to more serious diseases like freightercer and pneumonia.SBS was first identified in the 1970s, and its identification at this time beca wasting disease of the increasing number of electronic equipment and other factors. The term SBS is used when a large number of people occupying a particular create break symptoms associated with their presence in that building. Later on, the symptoms disappear. In most cases sick building syndrome occurs in office buildings, schools and apartment buildings.SBS is suspected when the following circumstances be correspondSym ptoms ar temporary and associated with time spent in a particular building or place.Symptoms disappear when the individual is not in the building.Symptoms reappear seasonally (heating, cooling).Symptoms and their severity are different from person to person.The signs and symptoms of a diagnosable illness are easy to identify and can be directed to specific mobile building contaminants. On the other hand, the cause(s) of symptoms in cases of SBS are often difficult to pin down and in many cases different factors may lead to the situation. When a sick building is identified an investigation should be done. Once the causes are identified, corrective measures must be taken to ensure that any adverse reception exhibited and cause(s) are isolated to chafe the realm safe for the students and school personnel.The prevalence of sick building syndrome is a problem, entirely statistics are limited. A World wellness Organization (WHO) overlay from 1984 suggested that up to 30% of brisk and renovated buildings worldwide may generate excessive complaints related to indoor air quality (1). This high rate may be associated with modern mass produced construction materials that tend to off load gas irritating volatile organic chemicals (VOCs). In a U.S. report on office workers questioned at random, 24% reported air quality problems in their work place, and 20% believed this harmed their ability to do their job effectively (2) (http//www.houseofplants.co.uk).Symptoms of SBS mess suffering from SBS present different symptoms, like other creators such asHeadachesEye infections and irritationsVisual impairment tremorsDamage to the central nervous system campaign noses and throat irritationsDry coughsDry, itchy skin and rashesDizziness and nauseaDifficulty in concent valuationFatigue and tirednessBreathing difficultiesPneumonia and chest infectionsCauses of SBSThe mechanism by which a building or anything within the building causes employees to become sick is unknown. Pro blem areas can be tardily identified and curative action taken afterward an investigation.Causes are listed on a lower floorBuilding design, maintenanceFailure of ventilating system systemInterior design factorsLevels of specific pollutants, humidity and temperatureMultiple chemicals acting in conclave to cause sicknessAge of buildingType of materials used in buildingSBS is associated with the presence of certain mechanisms and pollutants. Most of the symptoms appear because of known toxic do of high levels of certain chemicals. rough symptoms are chiefly allergic irritations which could result from various allergens in a building. Other symptoms are suggestive of those really see by sufferers of chemical sensitivity and many of the indoor pollutants.Occurs in building with ventilation problems and may occur along with upper respiratory tract infection, Or with direct contact with chemicals, dust and gases.Itchiness, soreness, redness, eye lashes drop and excessive tear prod uction.HeadacheTension, prolonged exposure to different irritant substances and long working hours. hassle across the forehead, begins in the back of the head and upper neck as a band-like tightness or pressure and may end with vomiting.FeverCaused by breathing water supply droplets from humidifiers or from an air filter ventilation system. Or exposure to chemicals that irritate the lungs and cause infection in the lung.Productive cough, aching limbs, headache, tiredness, lethargy and abdominal pain.Skin problemsOccurs in exposed areas because of the direct exposure to chemical and different irritant substances like painting materials and products.Rashes, batches, itchy, dry skin and may end with chronic skin inflammation.StressPhysical changes lack of sleep and new environment.Headaches, digestive dis hostels, fatigue and lethargy, sleeping disorders, skin disorders and isolation from community.Lung problemExposure to dust, ventilation problems and chemicals.Cough, breathlessnes s, may end with lung cancer.Throat ProblemsDry mucous membranes, ventilation problems and chemicals.Hoarseness, dry throat pain, recurrent throat infections and chronic Asthma.School EnvironmentStudents spend most of their twenty-four hours in the school its their second house. From that aspect, the school environment should be physically and emotionally safe, well disciplined, and conducive to learning. Safety is an important issue, which may affect the students physically and psychologically from this aspect, and there are important points that should be consideredStructure of the schoolSchool building structures consist of columns, structural walls, beams, floors, and roof structures, which provide their stability. School buildings increase invisible cracks in concrete columns, structural walls, beams and floors. At the beginning, they are not an important issue. With time, the school building moves, creating stresses at joints in materials which ends in small cracks appearing . However, this is the rule process of a structure settling in its foundation. But, with the presence of other factors it makes the issue more serious. The idea is to be able to differentiate. In the event of a major structural problem in a school building, it should be evaluated by a structural engineer, and corrective measures should be made accordingly.Special prudence should be made to these aspectsBending in columns, beams, and roof structureRotting in wood structural components and floor structureRusting of metal structural components e additionally in high humidity weatherROOFINGThe roof protects the school building from rain, sun, wind, and keeps water from getting into the school building. The waterproofing system should be kept in a proper way. To prevent problems from happening, the roof should be kept in good shape and annually maintained. structure EXTERIOR utilise different building materials in school buildings is common nowadays for example, using fashion blocks i n the walls and having exteriors as maintenance free as possible to inflict costs. But new school buildings may feature concrete blocks or brick walls even though fashion blocks in some walls are kept. The school buildings exteriors result still need annual maintenance plans to protect the materials. The plan will consider the type and quality of materials used and their current condition. Some school buildings are old, and the exterior may not be quite suitable for a maintenance free plan. The biggest threats to school buildings exteriors are water, sun, wind, and being in areas near the coast.BUILDING INTERIORThe design of the inside of a building is an important issue. Paint maintenance should be paid special attention, because it plays a major roll in preventing the deterioration of the building, and usually cracks are invisible when they superstart to appear. Also, the paint should be good quality to avoid any irritation reaction.GROUNDSThe area just about the school is mad e of concrete, but a pathway may be concrete, brick, stone, asphalt, or even wood. Such materials need good maintenance and must be watched for conditions that may cause major hazards such as slips and falls. Any major hazards should be eliminated through repair, ramping or clearing. Annual checkups and repairs must be done if the condition of the material deteriorates.ClassroomsHealthy classrooms are ones that have adequate ventilation, lighting, an adequate number of students per class, and proper classroom temperature. All previous points which were discussed should be use properly.Ventilation worthy Ventilation is important to the indoor air quality. Air-conditioning, the type of material used and maintenance also affect indoor air quality in order to optimise performance and prevent students becoming sick.Many factors may affect indoor air quality and contribute to many health problems, the comfort, and the performance of students.Temperature on that point are many causes of si ck building syndrome like uncontrolled temperature (high or low). If there is a wide variation in temperature, it will affect other factors such as the increasing possibility of exposure to fever and throat infections. Therefore, maintaining adequate temperature inside classrooms will allow the students to perform butter. One must make sure that dangerous or offensive fumes are prevented from escaping into the classroom through the heating or cooling system.humidnessHumidity can lead to different problems. It could vary from a simple one to a complicated one. For example, bacteria, fungi, and parasites live in places where humidity is preceding(prenominal) the normal levels, and they enter the body mainly through the respiratory system, resulting in some kind of respiratory infection. In classrooms, the range of controlled humidity is 40% to 70% in order to increase students effectiveness. The range of relative humidity in warm classrooms should be less than 40%. Therefore, there s hould be annual checking of controls on a regular basis, and also, checking should cover the cleanliness of equipment for humidifying. fitting lightingEnsure that there is adequate lighting in the classrooms and whole building to avoid a lot of problems.Surveys by the National Institute of Ophthalmology showed that or so 38.8 percent of students at 260 schools in Ho Chi Minh City have refraction problems, short-sightedness, far-sightedness, and astigmatism. The ratio in the northern Hai Phong City was 60 percent, while in Hanoi, Da Nang and the central Ha Tinh Province, it ranged from 25 percent to above 30 percent. Doctors attributed the high incidence of weak eyesight to substandard classrooms in terms of size, area and light, as well excessive time spent working with computers SummaryTo sum up, there are different factors that could affect the school environment, and some of them were discussed above. Some problems can be avoided by early detections and by finding proper solutio ns to avoid any health problems that arise. If a problem is detected earlier it can be solved during the design step or maybe later in order to maintain a safe school environment. SBS affects productivity, increases the rate of absenteeism, inadequate concentration and fatigue. It affects the well-being of the students and all school personnel and their performance. All the measures are directed to avoid and reduce the risk factors that affect student health.Task 2BREEAMBREEAM is a method used internationally to prize a buildings surrounding area. It can be applied to asses both new and old buildings. There are several types of environmental mind systems in use such as BREEAM, ESRSA, and CEEQUAL. Because it is used in two significant areas of the globe, BRE Global introduced two new geographic schemes that are use by BREEEAM International assessors which are BREEAM Europe and BREEAM Gulf. In addition to these two schemes, the BREEAM In Use and BREEAM Communities schemes are also accessible for use on international buildings and developments.Since BREEAM is astray used in Europe and as it used in the gulf, the BREEAM Gulf scheme can be used to assess the environmental impacts of any building located in the Gulf region. This will be explained later on in this paper.BREEAM provides designers, planner and others with key factorsIt ensures the best environmental practice is included in a buildingIt finds solutions that help to minimise the environmental impactIt ensures the use of high standards and regulationsIt reduces the costs and improves working and living environmentsIt reduces the time needed to finish the workSteps of BREEAM assessmentThere are two steps in BREEAM which can be used to evaluate the environmental effect secondary to building development1. Design Stage (DS)2. Post-Construction Stage (PCS)Design StageThis step should be done before construction deeds start. Related information should be available to enable the BREEAM assessor to demonstr ate, in a healthy manner, the buildings performance against the reporting and evidential requirements of the technical guidance. The official assessment of DS will be carried out at the detailed design stages.Post-Construction StageThis step starts after construction work has finished. In this step, an evaluation and the BREMM rating are used before building occupation.The post-construction stage is divided into two approaches1. A post-construction review of a design-stage assessment2. A post-construction assessmentA post-construction estimation aims to detect the BREEAM rating achieved at the design stage in accordance with the reporting and evidential requirements of the technical guidance. Where a formal DS assessment has not been carried out and a BREEAM assessment and rating is required, a full PCS assessment can be conducted.BREEAM GulfBREEAM Gulf has been developed and established in collaborationism with a variety of large organisations based in Qatar, Abu Dhabi and Dubai. The intent of the system is to bring all the new and used building types in the area into use. The available BREEAM system can be used to evaluate, demonstrate and improve the building environment.The system has been developed in the Gulf region to resemble UK BREEAM system categories it provides special assessment points in relation to environmental impacts associated with construction in the Gulf region.The BREEAM Gulf systemThe BREEAM system for the Gulf assessment point areas is as belowMaterialsWasteWaterManagementHealth and WellbeingLand Use and EcologyEnergyTransportPollutionDuring the assessment phase within apiece point from the above table, numbers of credits must be assessed to appraise the performance achieved by the development. This set of points is modified to fit the Gulf regions conditions and climate. They are applied to each point to enable the weighted scores to be added together to produce a single overall score for the building. Then, the score is translated into a 1-5 star rating and the highest level of environmental performance will score 5 stars.Unlike BREEAM in the UK which generally looks at building uses separately, a BREEAM assessment in the Gulf evaluates the performance of a whole building taking into account the different uses that are present (e.g. offices, retail, residential etc.). This approach reflects the construction market in theregion where mixed use buildings are the norm. The assessment, therefore, produces a single score for each assessed building based on an area weighted calculation.Differences with BREEAM in the UKThe purpose of BREEAM Gulf is to evaluate the construction industry in the region to achieve and maintain higher levels of sustainability. It also aims to identify local contexts and issues, and with this consideration, all of the codes and standards which should be maintained are described in the guidance.Figure3 factors affecting indoor environmentwww.yoshino-gypsum.com//sickhouse01.htmAppendixesCas e study 1The EPA (Environmental Protection Agency) has conducted a study about IAQ (indoor(a) Air Quality). William Blackstone wide-eyed School was one of three schools selected to pilot EPA Indoor Air Quality Tools for Schools (IAQ TfS) kit up and Program in 1999. The school is located in Bostons South closing and is one of 120 schools in the Boston Public School System. The school was built in 1975, using the typical design of that time brick walls, mostly mat roofs, Plexiglas windows, and visible duct work. It has a history of IAQ and health-related problems, specifically high rates of asthma among students. William Blackstone Elementary School was one of three schools selected to pilot EPA Indoor Air Quality Tools for Schools (IAQ TfS) Kit and Program in 1999. The school nurse noticed that the asthma rate was higher than the national average of two cases per classroom. staff were also aware of serious problems with water intrusion during heavy rain, stained and collapsed ce iling tiles, peeling paint and stains on the walls, rust on support beams, and water damage to equipment and furniture.Problem recognitionProblems identified by the checklists and walkthrough included the followingAn above-average number of asthma cases and illnesses typically associated with indoor air quality problems (headaches, nausea, etc.).Water damage, such as mold and mildew, missing, stained, and broken ceiling tiles, fungal growth on ceiling tiles, and damaged ceiling and wall plaster.Thermal discomfort, such as widely fluctuating temperatures, too high or too low humidity levels, and cold drafts.Ventilation problems, such as poor air circulation and lack of have fans in some bathrooms.Cleanliness problems, such as dust accumulation around the supply vents and surrounding ceiling tiles, infrequent dusting and vacuuming, and pest problems.So, according to the findings, the IAQ team was organise and they established a meeting to list the causes of the problems and find sol utions.ImprovementsThe IAQ team implemented some actions to improve the indoor air quality at Blackstone Elementary School. The EPAs IAQ TfS Kit gave the team the leverage it needed to persuade the school district to improve the environmental problems in the school. Once the Superintendent was informed of the schools IAQ issues and the teams recommendations, Blackstone Elementary was placed on a high-priority list for roof repairs and other renovations.A number of improvements have been done, including roof repairs. There is a plan for installing new energy-efficient lighting and new ceiling tiles. Additionally, carpets will be replaced with tiles in the classrooms. The school nurse started to assess students health and document any new asthma cases over the next course of instruction to establish a link between the indoor environment and childrens health.SummaryThe surrounding environment plays a role in students performance and affects their health directly. This sum that attent ion must be given at some point during design stage or later to avoid unwanted risky problems that may affect students health. Some problems can be detected easily like eye infections, but others like asthma will be treated but its effects are lifelong. Poor ventilation, lighting, humidity and temperature all can produce health problems therefore, good ventilation, adequate lighting, and proper temperature should be maintained. High performance building features should be incorporated into the design process, and school building systems should be commissioned to ensure that they are operating according to design.Case study 2 crop in schools is getting a lot of attention at local, state and federal levels, the Houston Chronicle reported in 2002. Wide variations in temperatures and humidity levels in South Texas make it difficult to maintain internal atmospheric conditions to minimise the formation of mold or mildew.Pharr-San Juan-Alamo School Districts Memorial High School, three ag e after it was established, faced a toxic mold problem that reached crisis stage. There were complaints from teachers, staff and students that some staff and students were becoming ill, and as a result students go forth the school. As with many schools, the indoor air quality at the school was poor because of high ventilation, the high number of students per classroom, high intermittent ventilation load and carryover from showers in gyms and locker rooms, and long periods where the building was vacant. There was an increase in heat, humidity, moisture, bad ventilation and filtration. The building had reached a saturation point. Leaks from the roof and windows contributed to the problem, and mold growth. Humidity inside the building was as high as 90 percent.Problem recognitionInstability of the weather (uncontrolled hot, humidity, moisture)Bad ventilation and filtrationLeaks from roof and window formulate growthSolutionCut off the source of moisture and mold removedFresh air from outside drawn to the building to regulate ventilationEquipment fixed to supply dry air to the building via temporary desiccant dryersCarpets exchanged for tilesImprovements outcomeAfter three months the desiccant dehumidification system driedthe buildingThe school is kept at 45 percent relative humidity and 75F tempThe mold growth is inhibited.Reduced absenteeism rate among students windupHealthy environments in school settings empower students to learn more and increase their effectiveness. It also helps school personnel to meet their goals in teaching and other work. From the above case study it can be seen that any problem in the school environment affects students health and learning ability. The problem can be easily detected by studying the causes and solving them. Many problems can be avoided byChoosing a good design of heating, ventilation, and air conditioningControlling moisture to prevent mold growth and preventing damage to building materials and systemsMaintenance of t he roof and windows
