Do a summary of RA 544: Civil engineering Law and print it in A3 size tarpaulin. you may use pictures, graphs or tables.
Visit a home improvement center (hardware/lumber store) in your town, and try to gather information about various types of insulating materials that can be used in a house. Write a brief report discussing the advantages, disadvantages, and characteristics of various insulating materials, including their thermal characteristics in terms of R-value.
R Value:
Wall: 0.961m2k/w
Floor: 0.676m2k/w
Roof: 0.7465m2k/w
In a table format show with calculations and research how much money you can save by installing a 115mm layer of insulation (R2.9) in your walls, floor and ceiling over a 5 and 10 year period. Consider the capital costs. Hint: State the current R value of each component. Convert to U value. Calculate new R value of each component (walls, floor and ceiling). Convert to U value. Use Q(W)=A*(change in U)*temperature change. Determine price for installation of new insulation. Determine price saved based on less heat loss through each component separately, then add all values together, and calculate per 5 years and per 10 years. Present all of this information in a table. You do not need to draw any diagrams, simply add the R value in series with your current components R values.
Assume the energy cost is 25 cents kWh
