A) In my state of Indiana, our energy code is the equivalent to ASHRAE 90.1-2007. Illinois is equivalent to 2012 IECC. Michigan is equivalent to ASHRAE 90.1-2007. Ohio is Equivalent to 2009 IECC.
B) GOOD
C)Good
2. What is needed in order to comply with the energy code (using the prescriptive approach presented in the PowerPoint) with regard to the unheated slab on grade for the Keystone Project? If the project were located in Montana, what would be the requirement for perimeter slab insulation?
Neither of them need any extra requirements for the unheated slab on grade.
D) DDDDDDDDDONE
3. Calculate the percentage of exterior wall composed of fenestration to verify that the area of fenestration is less than or equal to 40%.
29.22% good
4. Assume that the client would like to provide shading for the fenestrations on the south face of the building in order to protect the library books and resources from damage from the sun. Research methods to provide window shading and paste in a preliminary design that would provide shading such that the resulting projection factor does not restrict the use of windows based on the Solar Heat Gain Coefficient.
A good way to provide shade is to plant trees or to add external or internal shades.
E) DONE
5. Calculate the heat loss through the new second floor wall in the Keystone Library Renovation. Assume an interior temperature of 68 degrees F and an exterior temperature of 32 degrees F.
Area= 1078.63 , U-value= 1/1.67= .5988, delta T= 36 degrees
Q'= 23251.81
Conclusion
Q'= 23251.81
Conclusion
6. What is the purpose of energy codes?
To make sure that buildings are energy efficient.
7. How does adding a vestibule improve energy efficiency?
To reduce heat loss when opening the door.
8. What recommendations would you make to improve the energy efficiency of the existing structure during the renovation process for the Keystone Library?
I would add more insulation and add small plants to the green roof.
