SBS stands for Sick Building Syndrome. It covers a mixture of symptoms thought to be generated when a pupil at school spends clip in a peculiar edifice. The symptoms range from antsy eyes, tegument roseolas, and nasal allergy symptoms, to more complicated symptoms such as weariness, strivings, and sensitiveness to odours. On the other manus, it may be lead to more serious diseases like malignant neoplastic disease and pneumonia.

SBS was foremost identified in the 1970s, and its designation at this clip because of the increasing figure of electronic equipment and other factors. The term SBS is used when a big figure of people busying a peculiar edifice develop symptoms associated with their presence in that edifice. Later on, the symptoms disappear. In most instances sick edifice syndrome occurs in office edifices, schools and flat edifices.

A SBS is suspected when the undermentioned fortunes are present:

Symptoms are impermanent and associated with clip spent in a peculiar edifice or topographic point.

Symptoms disappear when the person is non in the edifice.

Symptoms reappear seasonally ( heating, chilling ) .

Symptoms and their badness are different from individual to person.A

The marks and symptoms of a diagnosable unwellness are easy to place and can be directed to specific airborne edifice contaminations. On the other manus, the cause ( s ) of symptoms in instances of SBS are frequently hard to trap down and in many instances different factors may take to the state of affairs. When a ill edifice is identified an probe should be done. Once the causes are identified, disciplinary steps must be taken to guarantee that any inauspicious reaction exhibited and cause ( s ) are isolated to do the country safe for the pupils and school forces.

The prevalence of ill edifice syndrome is a job, but statistics are limited. A World Health Organization ( WHO ) study from 1984 suggested that up to 30 % of new and renovated edifices worldwide may bring forth inordinate ailments related to indoor air quality ( 1 ) . This high rate may be associated with modern mass produced building stuffs that tend to murder burden gas annoying volatile organic chemicals ( VOCs ) . In a U.S. study on office workers questioned at random, 24 % reported air quality jobs in their work topographic point, and 20 % believed this harmed their ability to make their occupation efficaciously ( 2 ) ( hypertext transfer protocol: // ) .

Symptoms of SBS

Peoples enduring from SBS present different symptoms, like other conditions such as:


Eye infections and annoyances

Ocular damage shudders

Damage to the cardinal nervous system

Runing olfactory organs and pharynx annoyances

Dry coughs

Dry, antsy tegument and roseolas

Dizziness and sickness

Trouble in concentrating

Fatigue and fatigue

Breathing troubles

Pneumonia and chest infections

Causes of SBS

The mechanism by which a edifice or anything within the edifice causes employees to go ill is unknown. Problem countries can be easy identified and healing action taken after an probe.

Causes are listed below:

Building design, care

Failure of airing system

Interior design factors

Degrees of specific pollutants, humidness and temperature

Multiple chemicals moving in combination to do illness

Age of edifice

Type of stuffs used in edifice

SBS is associated with the presence of certain mechanisms and pollutants. Most of the symptoms appear because of known toxic effects of high degrees of certain chemicals. Some symptoms are chiefly allergic annoyances which could ensue from assorted allergens in a edifice. Other symptoms are implicative of those truly experienced by sick persons of chemical sensitiveness and many of the indoor pollutants.

Occurs in constructing with airing jobs and may happen along with upper respiratory piece of land infection, Or with direct contact with chemicals, dust and gases.

Itchiness, tenderness, inflammation, oculus ciliums bead and inordinate tear production.


Tension, drawn-out exposure to different irritant substances and long working hours.

Pain across the brow, begins in the dorsum of the caput and upper cervix as a band-like stringency or force per unit area and may stop with emesis.


Caused by take a breathing H2O droplets from humidifiers or from an air filter “ airing system ” . Or exposure to chemicals that irritate the lungs and cause infection in the lung.

Productive cough, hurting limbs, concern, fatigue, lassitude and abdominal hurting.

Skin jobs

Occurs in open countries because of the direct exposure to chemical and different irritant substances like painting stuffs and merchandises.

Rashes, batches, itchy, dry tegument and may stop with chronic tegument redness.


Physical alterations: deficiency of slumber and new environment.

Headaches, digestive upsets, weariness and lassitude, kiping upsets, tegument upsets and isolation from community.

Lung job

Exposure to dust, airing jobs and chemicals.

Cough, shortness of breath, may stop with lung malignant neoplastic disease.

Throat Problems

Dry mucose membranes, airing jobs and chemicals.

Hoarseness, dry pharynx hurting, recurrent pharynx infections and chronic Asthma.

School Environment

Students spend most of their twenty-four hours in the school ; it ‘s their 2nd house. From that facet, the school environment should be physically and emotionally safe, good disciplined, and contributing to larning. Safety is an of import issue, which may impact the pupils ‘ physically and psychologically from this facet, and there are of import points that should be considered:

Structure of the school:

School edifice constructions consist of columns, structural walls, beams, floors, and roof constructions, which provide their stableness. School edifices develop unseeable clefts in concrete columns, structural walls, beams and floors. At the beginning, they are non an of import issue. With clip, the school edifice moves, making emphasiss at articulations in stuffs which ends in little clefts looking. However, this is the normal procedure of a construction subsiding in its foundation. But, with the presence of other factors it makes the issue more serious. The thought is to be able to distinguish. In the event of a major structural job in a school edifice, it should be evaluated by a structural applied scientist, and disciplinary steps should be made consequently.

Particular attending should be made to these facets:

Bending in columns, beams, and roof construction

Decomposing in wood structural constituents and floor construction

Corroding of metal structural constituents particularly in high humidness conditions


The roof protects the school edifice from rain, Sun, air current, and keeps H2O from acquiring into the school edifice. The waterproofing system should be kept in a proper manner. To forestall jobs from go oning, the roof should be kept in good form and yearly maintained.

Building Outside

Using different edifice stuffs in school edifices is common presents ; for illustration, utilizing manner blocks in the walls and holding outsides as care free as possible to take down costs. But new school edifices may have concrete blocks or brick walls even though manner blocks in some walls are kept. The school edifices ‘ outsides will still necessitate one-year care programs to protect the stuffs. The program will see the type and quality of stuffs used and their current status. Some school edifices are old, and the outside may non be rather suited for a care free program. The biggest menaces to school edifices ‘ outsides are H2O, Sun, air current, and being in countries near the seashore.


The design of the interior of a edifice is an of import issue. Paint care should be paid particular attending, because it plays a major axial rotation in forestalling the impairment of the edifice, and normally clefts are unseeable when they start to look. Besides, the pigment should be good quality to avoid any annoyance reaction.


The country around the school is made of concrete, but a tract may be concrete, brick, rock, asphalt, or even wood. Such stuffs need good care and must be watched for conditions that may do major jeopardies such as faux pass and falls. Any major jeopardies should be eliminated through fix, raging or uncluttering. Annual medical examinations and fixs must be done if the status of the stuff deteriorates.


Healthy schoolrooms are 1s that have equal airing, illuming, an equal figure of pupils per category, and proper schoolroom temperature. All old points which were discussed should be applied decently.


Proper Ventilation is of import to the indoor air quality. Air-conditioning, the type of stuff used and care besides affect indoor air quality in order to optimize public presentation and prevent pupils going sick.

Many factors may impact indoor air quality and contribute to many wellness jobs, the comfort, and the public presentation of pupils.


There are many causes of ill constructing syndrome like uncontrolled temperature ( high or low ) . If there is a broad fluctuation in temperature, it will impact other factors such as the increasing possibility of exposure to fever and throat infections. Therefore, keeping equal temperature inside schoolrooms will let the pupils to execute butter. One must do certain that unsafe or violative exhausts are prevented from get awaying into the schoolroom through the warming or chilling system.


Humidity can take to different jobs. It could change from a simple one to a complicated one. For illustration, bacteriums, Fungis, and parasites live in topographic points where humidness is above the normal degrees, and they enter the organic structure chiefly through the respiratory system, ensuing in some sort of respiratory infection. In schoolrooms, the scope of controlled humidness is 40 % to 70 % in order to increase pupils ‘ effectivity. The scope of comparative humidness in warm schoolrooms should be less than 40 % . Therefore, there should be one-year checking of controls on a regular footing, and besides, look intoing should cover the cleanliness of equipment for humidifying.

Adequate lighting

Ensure that there is equal lighting in the schoolrooms and whole edifice to avoid a batch of jobs.

‘Surveys by the National Institute of Ophthalmology showed that around 38.8 per centum of pupils at 260 schools in Ho Chi Minh City have refraction jobs, short-sightedness, far-sightedness, and astigmia. The ratio in the northern Hai Phong City was 60 per centum, while in Hanoi, Da Nang and the cardinal Ha Tinh Province, it ranged from 25 per centum to above 30 per centum. Doctors attributed the high incidence of weak seeing to substandard schoolrooms in footings of size, country and visible radiation, as good inordinate clip spent working with computing machines ‘


To sum up, there are different factors that could impact the school environment, and some of them were discussed above. Some jobs can be avoided by early sensings and by happening proper solutions to avoid any wellness jobs that arise. If a job is detected earlier it can be solved during the design measure or possibly subsequently in order to keep a safe school environment. SBS affects productiveness, increases the rate of absenteeism, hapless concentration and weariness. It affects the wellbeing of the pupils and all school forces and their public presentation. All the steps are directed to avoid and cut down the hazard factors that affect pupil wellness.

Undertaking 2


BREEAM is a method used internationally to measure a edifice ‘s environing country. It can be applied to asses both new and old edifices. ‘There are several types of environmental assessment systems in usage such as BREEAM, ESRSA, and CEEQUAL. Because it is used in two important countries of the Earth, BRE Global introduced two new geographical strategies that are use by BREEEAM International assessors which are BREEAM Europe and BREEAM Gulf. In add-on to these two strategies, the BREEAM In Use and BREEAM Communities strategies are besides available for usage on international edifices and developments ‘ .

Since BREEAM is widely used in Europe and as it used in the gulf, the BREEAM Gulf strategy can be used to measure the environmental impacts of any edifice located in the Gulf part. This will be explained subsequently on in this paper.

BREEAM provides interior decorators, contriver and others with cardinal factors:

It ensures the best environmental pattern is included in a edifice

It finds solutions that help to understate the environmental impact

It ensures the usage of high criterions and ordinances

It reduces the costs and improves working and populating environments

It reduces the clip needed to complete the work

Stairss of BREEAM appraisal

There are two stairss in BREEAM which can be used to measure the environmental consequence secondary to constructing development:

1. Design Phase ( DS )

2. Post-Construction Phase ( PCS )

Design Phase

This measure should be done before building works start. Related information should be available to enable the BREEAM assessor to show, in a healthy mode, the edifice ‘s public presentation against the coverage and evidentiary demands of the proficient counsel. The official appraisal of DS will be carried out at the elaborate design phases.

Post-Construction Phase

This measure starts after building work has finished. In this measure, an rating and the BREMM evaluation are used before constructing business.

The post-construction phase is divided into two attacks:

1. A post-construction reappraisal of a design-stage appraisal

2. A post-construction appraisal

A post-construction assessment aims to observe the BREEAM evaluation achieved at the design phase in conformity with the coverage and evidentiary demands of the proficient counsel. Where a formal DS appraisal has non been carried out and a BREEAM appraisal and evaluation is required, a full PCS appraisal can be conducted.


BREEAM Gulf has been developed and established in coaction with a assortment of big administrations based in Qatar, Abu Dhabi and Dubai.

The intent of the system is to convey all the new and used edifice types in the country into usage. The available BREEAM system can be used to measure, demonstrate and better the edifice environment.

The system has been developed in the Gulf part to resemble UK BREEAM system classs ; it provides particular assessment points in relation to environmental impacts associated with building in the Gulf part.

The BREEAM Gulf system

The BREEAM system for the Gulf appraisal point countries is as below:





Health and Wellbeing

Land Use and Ecology




During the assessment stage within each point from the above tabular array, Numberss of credits must be assessed to measure the public presentation achieved by the development. This set of points is modified to suit the Gulf part ‘s conditions and clime. They are applied to each point to enable the leaden tonss to be added together to bring forth a individual overall mark for the edifice. Then, the mark is translated into a 1-5 star evaluation and the highest degree of environmental public presentation will hit 5 stars.

‘Unlike BREEAM in the UK which by and large looks at edifice utilizations individually, a BREEAM appraisal in the Gulf evaluates the public presentation of a whole edifice taking into history the different utilizations that are present ( e.g. offices, retail, residential etc. ) . This attack reflects the building market in theA part where assorted usage edifices are the norm. The appraisal, hence, produces a individual mark for each assessed edifice based on an country weighted computation ‘ .

Differences with BREEAM in the UK

The intent of BREEAM Gulf is to measure the building industry in the part to accomplish and keep higher degrees of sustainability. It besides aims to place local contexts and issues, and with this consideration, all of the codifications and criterions which should be maintained are described in the guidance.A

Figure3: factors impacting indoor environment … /sickhouse01.htm


Case study 1

The EPA ( Environmental Protection Agency ) has conducted a survey about IAQ ( Indoor Air Quality ) . William Blackstone Elementary School was one of three schools selected to fly EPA Indoor Air Quality Tools for Schools ( IAQ TfS ) Kit and Program in 1999. The school is located in Boston ‘s South End and is one of 120 schools in the Boston Public School System. The school was built in 1975, utilizing the typical design of that clip ; brick walls, largely level roofs, Plexiglas windows, and seeable canal work. It has a history of IAQ and health-related jobs, specifically high rates of asthma among pupils. William Blackstone Elementary School was one of three schools selected to fly 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 norm of two instances per schoolroom. Staff were besides cognizant of serious jobs with H2O invasion during heavy rain, stained and collapsed ceiling tiles, skining pigment and discolorations on the walls, rust on support beams, and H2O harm to equipment and furniture.

Problem acknowledgment

Problems identified by the checklists and walkthrough included the followers:

An above-average figure of asthma instances and illnesses typically associated with indoor air quality jobs ( concerns, sickness, etc. ) .

Water harm, such as cast and mold, losing, stained, and interrupt ceiling tiles, fungous growing on ceiling tiles, and damaged ceiling and wall plaster.

Thermal uncomfortableness, such as widely fluctuating temperatures, excessively high or excessively low humidness degrees, and cold bill of exchanges.

Ventilation jobs, such as hapless air circulation and deficiency of fumes fans in some bathrooms.

Cleanliness jobs, such as dust accretion around the supply blowholes and environing ceiling tiles, infrequent dusting and vacuuming, and pest jobs.

So, harmonizing to the findings, the IAQ squad was formed and they established a meeting to name the causes of the jobs and happen solutions.


The IAQ squad implemented some actions to better the indoor air quality at Blackstone Elementary School. The EPA ‘s IAQ TfS Kit gave the squad the purchase it needed to carry the school territory to better the environmental jobs in the school. Once the Superintendent was informed of the school ‘s IAQ issues and the squad ‘s recommendations, Blackstone Elementary was placed on a high-priority list for roof fixs and other redevelopments.

A figure of betterments have been done, including roof fixs. There is a program for put ining new energy-efficient lighting and new ceiling tiles. Additionally, rugs will be replaced with tiles in the schoolrooms. The school nurse started to measure pupils ‘ wellness and papers any new asthma instances over the following twelvemonth to set up a nexus between the indoor environment and kids ‘s wellness.


The environing environment plays a function in pupils ‘ public presentation and affects their wellness straight. This means that attending must be given at some point during design phase or subsequently to avoid unwanted hazardous jobs that may impact pupils ‘ wellness. Some jobs can be detected easy like oculus infections, but others like asthma will be treated but its effects are womb-to-tomb. Poor airing, illuming, humidness and temperature all can bring forth wellness jobs ; hence, good airing, equal lighting, and proper temperature should be maintained. High public presentation edifice characteristics should be incorporated into the design procedure, and school edifice systems should be commissioned to guarantee that they are runing harmonizing to design.

Case study 2

Mold in schools is acquiring a batch of attending at local, province and federal degrees, the Houston Chronicle reported in 2002. Wide fluctuations in temperatures and humidness degrees in South Texas make it hard to keep internal atmospheric conditions to understate the formation of cast or mold.

Pharr-San Juan-Alamo School District ‘s Memorial High School, three old ages after it was established, faced a toxic cast job that reached crisis phase. There were ailments from instructors, staff and pupils that some staff and pupils were going ailment, and as a consequence pupils left the school. As with many schools, the indoor air quality at the school was hapless because of high airing, the high figure of pupils per schoolroom, high intermittent airing tonss and carryover from showers in gyms and cabinet suites, and long periods where the edifice was vacant. There was an addition in heat, humidness, wet, bad airing and filtration. The edifice had reached a impregnation point. Leaks from the roof and Windowss contributed to the job, and mold growing. Humidity inside the edifice was every bit high as 90 per centum.

Problem acknowledgment

Instability of the conditions ( uncontrolled hot, humidness, wet )

Bad airing and filtration

Leaks from roof and window

Mold growing


Cut off the beginning of wet and cast removed

Fresh air from outside drawn to the edifice to modulate airing

Equipment fixed to provide dry air to the edifice via impermanent drying agent driers

Rugs exchanged for tiles

Improvements outcome

After three months the desiccant dehumidification system dried

the edifice

The school is kept at 45 per centum comparative humidness and 75A°F temp

The mold growing is inhibited.

Reduced absenteeism rate among pupils


Healthy environments in school scenes empower pupils to larn more and increase their effectivity. It besides helps school forces to run into their ends in instruction and other work. From the above instance analyze it can be seen that any job in the school environment affects pupils ‘ wellness and acquisition ability. The job can be easy detected by analyzing the causes and work outing them. Many jobs can be avoided by:

Choosing a good design of warming, airing, and air conditioning

Controling wet to forestall mold growing and forestalling harm to edifice stuffs and systems

Care of the roof and Windowss
