TO MY PRESENTATION
ON
Building Energy Conservation and
Wall Thermal Insulation Case Study

2. Introduction
 Energy Performance In
Existing Buildings Thermal
Conductivity of Wall &
Retrofitting of Wall Materials
Characteristics of Insulating
Materials. Determination of
Optimum value thermal
conductivity of wall.

3. Research Aims

Methodology
 Select What Types Of Wall
 Inspect And Measure The
Thickness Of Wall
 Determine The R,U,K-value Of
Previously Installed Wall .
 Wall Surface Plastering Insulated
Wall
 Insulating Materials EPS add
 Air Gap
 Surface Finishing

6. Result & Discussion:
 Thermal Conductivity is
Change to Temperature
Thermal Conductivity is
Change to Wall
Thickness
 Thermal Conductivity
Change to Wall Panel
Number

7.  Thermal Conductivity
Characteristics Experienced
in Different Season in typical
Section and Changing Value
of Thermal Transmittance(u-
value)
 Energy Conservation Change
Experienced
due to Temperature
 Demand of Energy Curve
Change With Season

9.  Demand Energy at High Per
Yearly
 Electricity Consumption
Increased With Growth
Population
 Carrying Capacity Is a Measure
of The Environment’s ability To
Support a Given Population
 Early Populations Grow Quickly,
Unimpeded by Resource
Constraints.

11. Conclusions & Future Recommendations
 Improving The U-value Expectation
 Wall Insulation Solutions Added
EPS Insulating Solutions due to U-
optimum Value
 Future Control to Co2 Emissions
 Energy Save & Demand Fulfilled
Excess Growth Population
