R301- Design criteria As stipulated in R301.3 of the 2009 International Residential Code the residence shall comply with part 3, that the masonry walls must be at a maximum height of 12 feet plus a height of floor framing to not exceed 16 inches. An additional 8 feet is permitted for gable and end walls. The primary residence meets section R301.3 as the floor to ceiling heights have been lowered to 8 feet in recent renovations.
R303.7 Required glazed openings As stipulated in R303.7 of the 2009 International Residential Code (IRC2009), glazing under code requirements must open directly to a street, public alley, a yard, or a court. The residence meets this condition as the glazing opens up to the street on the Southeast face, the side yard along the East and the neighboring lot on the West.

Section 602.3 As stipulated in 602.3 of the 2009 International Building Code Section the residences discussed in this project follow Type III building classification. The exterior of the building must be constructed of masonry walls which are noncombustible and the interior of the building must meet code. The fire-rating of the exterior baring walls must be at least 2 hours. The construction has to follow a brick and joist structure that has masonry load bearing walls. The floors and other structural framework are made of wood or of another combustible material. The residences meet section 602.3 as the exterior construction is noncombustible masonry with a fire-rating of at least two hours. The interior construction is composed of lumber joists and studs. As stipulated in section 602 of the International Building Code the fire rating resistance is classified as “B” since all the structural member are un-protected and have no additional fire rated coating of cover. The residences are classified as “B” construction due to the lack of fire rating cover on interior structural members. R311- Means of egress As stipulated in R311.1 of the 2009 International Residential Code all stairways, ramps, and exits shall comply with criteria governing means of egress for the projects described in this document.

SUN STUDIES OF ADAPTIVE TRANSFORMATION
Using the available sun along the existing southwest porch our adaptive transformation allows sun to penetrate to the living area. By encasing the porch in glass the living space can be extended to the front of the home and can integrate the porch culture year round. Passive heating strategies can be utilized through the winter to lower heating costs and maxmize daylight. These series of sun studies show the sun and shading conditions through various months of the year at 9am, 12pm, and 3pm. In the winter months the living space can maximize the available sunlight and in the summer months the living space is shaded through the trellis structure and plantings.

The current situation and materials used on the site do not allow for effective rain water management. The concrete driveway and backyard make it impossible to manage rain water. Adding a rain garden in the backyard will minimize the water runoff during a storm and allows for better infiltration. Using a bottle rain gutter collector will allow the resident to collect water that can be used for upkeep fo the front garden.

RAIN GARDEN SIZE & PLACEMENT Determine the rain garden size base on the size of the drainage area. In doring so, residents will have to opproximate the size of their roof. We have situated the rain garden in the back of the house, since two third of the rain will be feeding the back downspout. And we have estimated that the roof area ia 666 sf. Requirements include that the garden must be placed at least ten feet from the foundation. The rain garden area is based on both the soil type and depth of the rain garden basin. The garden will be 3”-5” (required for silty soil as found ont he site). It will be placed fifteen feet back from the house and have a total area of 166 sq.ft.
