Conclusion

1. What is important to consider when designing an HVAC system?

Efficiency along with site orientation, air infiltration, and many other factors are important to consider when designing an HVAC system.

2. How does the HVAC system affect the design of the building structure?

It would affect the design of the building because you would need to desgin specific rooms to support the system.

3. How does an engineer know the requirements for mechanical design of an HVAC system?

The engineer would know the requirements by reading and using the codes that correspond to the specific area.

4. Why is it important for architects to be aware of how mechanical systems are designed or constructed?

Because, the architect must design the building around the requirements for the mechanical systems based on things like space needed for the systems.

5. What information must an architect provide to a mechanical engineer to ensure proper design and placement of the mechanical systems?
The archictect would need to provide the layout and building plans so that the mechanichal engineer would be able to design the systems properly according to the building.

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 the state of 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?
None have the requierments.


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 could 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.

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 few of the ways to improve 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.

Activity 3.1.1

1.    Identify the Building Code that applies in Noblesville by reviewing Section 154.04 Adoption of Rules by Reference in the Noblesville Code of Ordinances.

 Indiana Building Code 2009.

2.    Visit the Indiana Association of Building Officials website at http://www.iabo.com/ and follow the link to Current Codes. On which model code is the current Indiana Building Code based?

 Based on: 2006 International Building Code (1st printing) with Indiana Amendments, Effective June 16, 2008.

3.    Using the International Building Code, find the Use and Occupancy classification of the proposed new Keystone Building. 

303.1 Assembly Group A3.

4.    Using the International Building Code, describe each of the four types of construction. Based on the existing structure, under which of these types of construction could the Keystone Building fall? See section 503.1. 

1.  Steel Framing Encased in Concrete

2. Steel Framing

3. Noncombustible material

4. Heavy timber

Any materials allowed by code may be used.

5.    Compare the allowable Building Heights and Areas (IBC 2009 Table 503) for the Keystone Library using different construction types. What is the least restrictive construction type that can be used for the Keystone Library? Is a fire-protective layer required over the structural elements? Note: The letter A indicates that the structural members are protected by a fire-rated coating or cover (sheetrock, spray on, or another approved method). The letter B indicates that the structural members are not protected by an additional fire-rated coating or cover. 

Area of first floor =9424 ft2

Type Three B

6.    What materials do you propose to use for the new interior walls and floor for the Keystone Building? Justify your answer.

Fire treated wood interior or brick.

7.    Use the IBC to determine the Occupant Load (IBC 2009 Section 1004) for the Keystone Building assuming a second floor is added per the Keystone Library Renovation Preliminary Building plans (see Revit file). For now, conservatively assume that the second floor is entirely stacks and that the first floor is entirely reading rooms. In addition, because there is currently no plan to include an outside stairway to the roof, assume that the occupants of the green roof must exit through the 2^nd floor. The building inspector has determined, based on the planned use of the green roof as additional reading area, that the occupant load for the green roof may be based on the requirements for reading rooms.

First Floor Area = 8833ft2

17 people can be on floor one

Second Floor area 4453ft2

45 people

Green Room area 4380ft2

88 people

            Total occupant load 310 people.

8.    The occupant load is used to determine the minimum egress width for the building. Use the IBC to determine the required total egress width (IBC 2009 Section 1005) for the Keystone Building including the second floor.

Total Egress width

311 occupation total* .02inches =62.2inches

Required star egress from 2^nd floor.

.03 inches * (44+88) occupants= 40.2 inches

9.    What is the minimum number of exits required for the Occupant Load (IBC 2009 Section 1021)?

Minimum is 2 exits.

10. Read IBC 2009 Section 1021.2. Is it permissible to have only a single exit from the ground floor? From the second floor? Justify your answers.

No, there are too many people.

The answers to the following questions should be researched in the Noblesville Code of Ordinances and the Noblesville Zoning Map.

2.3 Essential Qustions

1.     How do you achieve a balance between cost-saving measures, important features, and environmental responsibility when designing a residential structure?

A way to achieve a balance between cost-saving would be to use energy efficient appliances, also building from a material that is high quality and environmentally friendly.

2.     What are the advantages and disadvantages of using 3D architectural software rather than creating hand-produced plans?

An advantage to using 3D architectural software would be the ability to emphasize details and create 3D view that you are unable to design on paper.  A disadvantage would be that hand drawn sketches are much quicker and simpler than 3D software.

3.     Why are organizations such as LEED important?

Organizations such as LEED are important, because they keep buildings environmentally friendly and efficient.  

4.     When planning a project, how does the availability of public utilities impact the design?

The availability of public utilities impact the design by possibly changing the location or direction the home is pointed to align the pipes, roads, ect.  

5.     What options are available for the management of wastewater from a building?

Some wastewater management options are a septic tank for out in the country or public sewer systems for residents in the city.

6.     What are the important considerations when design a plumbing system?

When designing the plumbing system some important consideration is where you put the water heater because you want to make sure that its not near and outside wall and its close to your appliances.

7.     Why should a designer know about the different types of lighting and their applications?

A designer should know about different types of lighting and their applications, because it can be more ecofriendly.  Like sky lights, and windows in certain rooms.

8.     What are the important considerations when designing an electrical system?

A consideration when designing an electrical system is safety, and where the outlets and switches are going to be placed and what lights the connect to.

9.     What information is important when documenting the design of a building?

Dimensioned floor plans, room schedules, wall section views, and labeled materials are all important to document in the designing of a building.
