1. Follow the link to What’s Happening in Your State. Based on the map and key, what is the status of the energy codes in Indiana (where the Keystone Library building is located)? What is the energy code status in neighboring states? What is the energy code status in your state?
In my state, Indiana, the status of the energy codes is equivelant to ASHRAE 90.1-2007. The nieghboring states of illinois, Michigan, and Ohio have different energy code status'. Illinois: 2012 IECC, Michigan: ASHRAE 90.1-2007, Ohio: 2009 IECC
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?
Niether have requirements.

3. Calculate the percentage of exterior wall composed of fenestration to verify that the area of fenestration is less than or equal to 40%.
3177.87/10047.71= .31627 32 %
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.

You would use overhangs to provide shading
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.
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 of Curtain Wall: 1174.40
Delta T: 36 Degrees
U Value: .5988
Formula: Q=A*U*DeltaT
36*.5988*1070.49=21270.74 BTU/hour
Conclusion

6. What is the purpose of energy codes?
The purpose of energy codes are to make sure that the building is an appropraite level of efficiency
7. How does adding a vestibule improve energy efficiency?
A vestible allows cold air to not enter into the building during the winter and for cool air to stay in during the summer.
8. What recommendations would you make to improve the energy efficiency of the existing structure during the renovation process for the Keystone Library?
A couple of ways to improove the energy effeciency of the Keystone library would be to add solar panals to the second level, along with high sky lights to gain light and produce heat.
