Project in building physics
The report must be written in such a way that it is self-explanatory.
All reports will be checked for plagiarism
The report applies to typical buildings in Norway / Sweden / Denmark.
INFORMATION
You need to choose a home, possibly your own.
The assignment is about the climate shell of the home you choose. That is, the construction that separates the outdoor environment. Some of the building components are visible, some can be measured and some you have to assume.
If you live so that you do not have a roof (block), you should still draw the roof. Same for floor.
A picture of that home you choose must be put in first page in the assignment, together with a short description (type of building, estimated year of construction, etc.).
Minimum requirements for detailed drawings:
1. All details shall show all relevant layers.
2. All layers must have text and text arrows indicating function and material.
Drawings must be neat, and all layers must be easy to see. Draw large.
4. Insulation layers must be targeted.
TASK 1
Draw a typical vertical section of the wall. Draw a section height that shows typical construction.
Draw by hand. Mark all the parts/sections by name.
Example:
Measure the wall thickness. Insulation thickness must be stated.
Reason/Explain assumed structure: What you have done to determine the structure and
what uncertainties exist.
TASK 2
Draw by hand a typical vertical section of the roof. Draw typical construction of a section width of the roof. Measure the thickness of the floor divider as well.
What is basis for assumptions of insulation thickness?
Look for roofs that in principle are like yours (wood / concrete) and make assumptions based on Technical Regulations under the Norwegian engineering and construction solutions.
Old roofs will have significantly less insulation.
Reason/Explain assumed structure: What you have done to determine the structure and
what uncertainties exist.
TASK 3
Draw by hand a typical vertical section of the floor. Draw typical construction of a section width of the floor. (Not joints). Measure the thickness as well.
What is basis for assumptions of insulation thickness?
Look for floors that in principle are like yours (wood / concrete) and make assumptions
based on Technical Regulations under the Norwegian engineering and construction solutions. Old floors will have significantly less insulation.
TASK 4:
Select task 1, 2 or 3. For each of the building parts, perform U-value calculations as accurately as possible. Specify necessary assumptions and comment the consequence of these. When using Excel, Excel sheets should be attached as attachment in the answer.
TASK 5:
Compare the details from task 1-4 for the different building parts and discuss advantages and disadvantages. Assess whether they meet the current U-value requirements according to table
from TEK17 § 14-2 b) See Appendix 1
TASK 6:
Estimate the transmission heat loss through a wall in this home,
compare the result to another home with different U-value (Give example of another type of home so that you can compare them). Comment on differences and suggest improvements such that can reduce transmission heat loss.
