Conclusion.

1.    What is important to consider when designing an HVAC system?
The size and location is important in designing and HVAC system.
2.    How does the HVAC system affect the design of the building structure?
You have to centralize the system and the bigger the building, the bigger HVAC system you need.
3.    How does an engineer know the requirements for mechanical design of an HVAC system?
You could have uneven pressure and distribution of air.
4.    Why is it important for architects to be aware of how mechanical systems are designed or constructed?
So they know how to use them at their full capacity. 
5.    What information must an architect provide to a mechanical engineer to ensure proper design and placement of the mechanical systems?
The placement of the rooms and the r-values of the outside walls.

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? 
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

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.
