Habitat for Humanity House Project

Description
The affordable housing project I designed is a Habitat for Humanity house located in Noblesville, IN. A map of the area is provided below. This house was designed for the Woodward family, a family of two. There is one adult and one child sharing a two bedroom home. Incorporated into the house are the following sustainable design features: Feasible daylighting and Energy Star rated appliances. Being constrained to the Habitat for Humanity guidelines, I had to keep the house within 900 square feet. To give the relatively small home an open and, thus, larger feeling, I arranged all of the home's rooms around an open living room/kitchen/dining room area that was separated with a small partician to save space, provide an open, flowing atmosphere, with some privacy to those in the kitchen and dining area. The client originally wanted an attached porch, but after incorporating it into the design, it put the total area over the limit. Removing it, however, put the area somewhat under the limit so I enlarged the size of the bathroom. We agreed that this was an acceptable compramize.

Part 1: Calculation of site runoff prior to addition of parking lotPre-development

Pre-development  (for 100 year storm)

Q = CfCiA
C = 0.1
i = 3.05
A = 0.5 acres (from site plan)
Q= (1.25)(0.1)(3.05)(0.5) = 0.2 cfs

Post-development (for 100 year storm)
Q = CfCiA
C (grass) = 0.1
C (asphalt) = .95
C (roof) = .95
i = 3.05
A (grass) = 0.47 acres
A (roof) = 0.02 acres 
A (drive way) = 0.01 acres
Q = [(1.05)(0.1)(3.05)(0.47)] + [(1.05)(0.95)(3.05)(0.02)] + [(1.05)(0.95)(3.05)(0.01)]
Q = 0.15 + 0.06 + 0.03
Q = 0.24
Change in runoff

ΔQ = Qpost - Qpre 

ΔQ = 0.24 - 0.2

ΔQ = 0.04
The change in runoff of the post development site is .04. Digging a small ditch will provide proper space for the water to go.

Shed Project

Activity 2.3.2 Green and Sustainable Energy

1.  Rainfall falls on most parcels of property throughout the world. Describe one method that could be used to collect this natural resource.

Website: http://www.rainxchange.com/
This method of rainfall collection uses the gutter system of the house through making the whole system continuous, leading the water into a filter an then into a storage tank underneath the ground.  The water can be reused if a pump is put into the storage tank.

2.  Describe an innovative construction method or technique that benefits the environment.

Website: http://enertia.com/

Solar Pannels "harvest" the suns energy and uses the electricity gathered to power things in the home or building.

3.   During the construction cycle of the building, materials and components are delivered to the site. List a strategy that you will use to recycle the waste produced during the construction phase. 

Website: http://www.mass.gov/dep/recycle/reduce/cdrguide.pdf

This Company recycles and reuses the wastes produced in the construction cycle.  Using this contact information and using this company to recycle the left over metals and wood would be a very efficient strategy to use.

4.  Energy use is high in commercial buildings. What might a designer do to reduce energy consumption in a building?

Website: http://eartheasy.com/live_energyeff_lighting.htm
A designer might plan for all of the lights in the house to be LFCs to reduce electrical consumption and to use all energy star equipment and utilities.

5.   Building sites offer natural resources that can be utilized for the life of the building. Describe a method to use a site’s natural resources in the construction of the structure.        

Website: http://www.greenstoneslate.com/

If the building was built in a place where slate was abundant than roofing the building with slate would be an efficient choice.  A back draw of this idea is that not too many buildings will be build around a slate quarry.

Conclusion

Describe an original green and sustainable idea that you have. Choose one that is not currently in use as far as you know.

 

Hydrogen power in place of petroleum or diesel fuel is a much more effeciant way of powering our cars. It produces smaller amounts of pollution and is a more sustainable energy source, as there is so much water to extract hydrogen from.

Describe an improvement that you believe could be made to the building where you live. Describe why it is an improvement.

An improvement to my house more efficient windows and heating systems.  This would lower heating costs in my house.
