2. Topic -2
• Formulate Hypothesis

3. Objective of study
• To formulate a hypothesis & identify all the
possible variables :
• To study three buildings in my region & find
out how user friendly they are.

4. Thermal comfort & student
performance in KPK Region:
Relationships & effects of temperature
on student performance
• “ The school Buildings which are provided by
active or passive cooling techniques i.e. some
how they achieved thermal comfort their
students will show better performance as
compared to where there is no or low thermal
comfort”

5. What is thermal comfort?

6. • According to the ANSI/ASHRAE Standard 55-
2010, thermal comfort is defined as “that
condition of mind which expresses satisfaction
with the thermal environment .

9. Methodology:
Study Area
• Selected three schools in KPK region at Swabi
district under KPK government
• Gov.Primary school no-1 jalsai village
• Gov.Primary school no-2 jalsai village
• Gov.Primary school no-4 jalsai village

10. population
• class-5 were constituted the population*
complete collection to be studied

11. sample
• I selected top five students as a purposive
sample*
subset of the population
*focuses on a particular subset of a population

12. Data Collection
• Objective and self-report instruments* were
used for data collection.
• The objective instrument involved physical
measurement of the classrooms and of the
indoor temperature, relative humidity and air
movement.
*means of collecting information for your study is called a research tool or a research instrument.

13. Cont.
• The self-report instrument* was a
questionnaire that asked for the students
perceived thermal discomfort levels.
*in which respondents read the question and select a response
by themselves without researcher interference

14. Predicted Mean Vote
• The Predicted Mean Vote (PMV) refers to a thermal
scale that runs from Cold (-3) to Hot (+3)
• Predicted Mean Vote sensation scale Value Sensation
• -3 Cold
• -2 Cool
• -1 Slightly cool
• 0 Neutral
• 1 Slightly warm
• 2 Warm
• 3 Hot

15. Cont.
• I prepared three lectures at three consecutive
days related to their mathematics courses and
deliver it in the mentioned three schools
having different thermal comfort variables &
recorded the overall performances of the
children.

16. Area of study
• I selected my own region “Peshawar”
• Temperature is very high in June-July months

17. Gov. primary school no-1
Highest thermal comfort

18. Sun shade

19. Gov. primary school no-2

20. Gov. primary school no-4
Low thermal
comfort

21. Scores on first day
school Primary-1 Primary-2 Primary-4
Score (average) 88.34 56 15.34

22. Scores on second day
school Primary-1 Primary-2 Primary-4
Score (average) 44.5 78.5 88.5

23. Scores on third day
school Primary-1 Primary-2 Primary-4
Score (average) 86 78.5 75.5

24. “Climate shapes how people live, it affects the culture in ways that we don’t think
about in our daily lives,” said Brad Bushman, co-author of the study and professor
of communication and psychology at The Ohio State University.

25. Results
• The results were astonishing:
• The students who were taught outdoor under
a tree give me maximum scores in their tests
when provided at the end of the lecture.
• The same students provided low performance
when taught in the class the next day where
there were fan but load shedding hours.

26. Conclusions:
• As the study indicated conducted in the
classrooms that the solar radiation is the
main aspects for heating of classrooms. To
increase student performance the
government must provide thermal comfort
either passive or active.
