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 = CfCiAC = 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.

ReplyDeleteSite plan- I don’t know what those things are in the back yard, but they are way too big to place in your site. 4.5/5

Dimensioned Floor Plan- The simple and open design works because of the small space. I’m not even sure the wall separating the kitchen is a good idea, but the open space still works. The only problem is the chain gun in the small bedroom, which an architect would not want in his plans. 4.5/5
Elevations- 5/5
Wall Section with labels- Good . 5/5
Window and Door Schedule- Not all windows are tagged. 4/5

Plumbing Plan with key- The clothes washer needs cold water as well. Also, it is inefficient to place one hot water appliance across the house. 4/5

Overall nicely done. Your simple design kept your project manageable. You might want to think of the additional sustainable design elements you can incorporate into your house, since efficiency of key with these houses (or any building). 70/75
