An Assessment Of Cross Ventilation In Public Buildings

1.2 MOTIVATION 

The interest to carry on this research work was triggered by the fact that churches, schools and hospitals are tagged and is known to be public building which host large crowds and therefore natural cross ventilation is very key in achieving comforts and also prevents suffocations; and other air bone diseases.

Therefore, it is indispensable to supply the building with fresh air, and insufficient ventilation can cause tiredness, lack of concentration or headache. Cross ventilation offers the means to control air quality in buildings, haven witnessed the even that took place in one of these churches in Jos North area of Plateau State, it was so terrible at a point one may have lost his or her life. In trying to get the fact on the occurrence, I found out that, the people who were directly involved and affected said that, suddenly there was a teargas by the police men around the church premises, and because of the crowd and lack of ventilation in the church many people almost lost their lives. It is on this note that ventilation as it were, is very important in human life and gave rise to the need for this research work.

1.3 STATEMENT OF THE PROBLEM 

It is the aim of the study to analyze the level of performance of natural air Ventilation with a case study of some Churches, Schools and Hospitals in Jos North Area of Plateau State. The absence of professionals left many people incapacitated, I discovered that most buildings in Jos north Area of Plateau State were not built by professionals. In view of the aforementioned, the research will linger in identifying how can the erection of building follow setting standards and established guidelines that would put human safety(health), human comforts and guaranty proper cultural heritage and thereby guaranteeing a qualitative and sustenance of good standard of living, with respect to provision of basic necessities of life (like food and shelter).  

1.4 AIM OF THE STUDY

The aim of this study is to facilitate Cross ventilation in Public Buildings.

1.5 OBJECTIVE OF THE STUDY

The aim of the study is to be achieved through the followings objectives;

1. Investigate the current trend.

2. Proper Orientation of buildings with respect to their openings.

3. Provide good fenestration so as to facilitate good ventilation and lightening in buildings.

4. The use of landscape as microclimate control.

1.6 SCOPE OF THE STUDY

Due to some constraints which includes; financial constraint, time constraint and geographical constraint, the researchers focused on practices and effects of cross ventilated public buildings citing the research work to Jos metropolis as the research findings can be used for proper solutions to erecting of buildings in Nigeria in retrospect

1.7 SIGNIFICANCE OF THE STUDY

The findings from this research will hopefully give an understanding of how to achieve cross ventilation in public buildings. The information gotten from this study shall provide a guide which can be used towards achieving good cross ventilation as it relates to sustainability.

1.8 RESEARCH METHODOLOGY

The study would examine the existing literature related to the topic subjected in review. The study would adopt a survey method in form of questionnaires because it gives the opportunity to make inferences about the characteristics of a population which is the purpose of the study.

The following means would be employed in the collection and collation of the data for this research work: the data obtain for the research work subjected and tested by the use of statistical tools and statistical means of analysis, the statistical tool employed were to be analyses descriptively.

1. Primary data: personal study carried out through the collection of data in the form of questionnaires administered to the occupants of public buildings and site investigation as well.

2. Secondary data: data sourced from various books, articles, journals written on the subject of appraisal. This would be done with view to having a proper, well researched subject by extracting relevant information which would aid in buttressing the aim and objectives of this research.
