Live, Grow, Sustain
Our design for the 2010
USGBC Natural Talent Design Competition seeks to promote three simple tenets of
a sustainable healthy lifestyle. These ideas are indicative of the
Broadmoor neighborhood's success in renewing their community after the
devastation brought by Hurricane Katrina. Since then, the community has strived
to rebuild their neighborhood not just for the present but for the
future. Our design aims to bring in sustainable design and construction
techniques while maintaining the character of this close nit and historic
community.
Live
The Live portion of the
design concept engages the relationship between the different spaces that
comprise a home. The house itself is organized in to three zones: Public,
Interstitial, and Private. The front porch is one of the most
important social areas of a home. It is from this place that the
residents of the neighborhood are able to interact with other members of the
neighborhood. The relationship between the front porch and street is
crucial to how the delicate relationship between the public and private spaces
of the house are organized. Our design seeks to maximize this space and
expand it across the entire frontage. The hub of the Living zone is the
living room with its naturally lit open floor plan along with spaces for eating
and studying. The Interstitial zone comprises the kitchen and the outdoor
sunken patio. The kitchen serves as the connector between the public and
private zones of the house. The majority of the cabinetry is located on
the floor for greater access. The windows are located on both sides of
the kitchen to allow for cross ventilation and views to the outdoor cistern on
the east side and patio on west side. The outdoor sunken patio is meant to be a
place of relaxation allowing residents to be outside in a more private area
away from the street. The third zone is the private zone which comprises
the bedrooms, bathrooms, and laundry. These spaces are tucked into the
back so that they are away from the noise of the public zones. These
three zones: Public, Interstitial, and Private, help to foster interaction with
the community and a healthier home.
Grow
One of our design goals
is to integrate nature and vegetation not only in the landscape but in the house
as well. The street side of the house features a small garden that will
have native vegetation. The north side of the house has a garden that can
be used to grow some of the resident's vegetables as well as any other variety
of plant that the resident enjoys. The outdoor sunken patio features a
trellis that covers the patio where planted vines can grow and provide shade in
the summer. The vines will act as a cover from the sun during the day and
also mitigate the amount of sunlight coming into the house and cut the cooling
energy costs of the home. The roofs are used help direct water to a central
cistern beside the kitchen. This cistern can be used for reducing the
amount of potable water needed for watering the landscaped areas.
Sustain
Just as the Broadmoor
neighborhood is renewing and rebuilding itself, it is important to think of how
the current development impacts the future of the neighborhood. Primary
focus is placed on site and accessibility, the use of renewable and recyclable
materials, and reducing energy consumption. The Broadmoor neighborhood is
located in a unique area of New Orleans. The topographical conditions
necessitated that to reduce the destruction caused by flood, the house would
need to be elevated no less than seven feet from the ground. The house is
organized as a single level home. The front stair is designed to
accommodate a standard residential chair lift if the need arises. Once at the
main floor level, the resident can reach all parts of the house, including
using a ADA compliant ramp to access the outdoor patio. Another emphasis
is on utilizing renewable and recyclable materials in the home. The
selection of durable materials will help increase the overall usage of the
house. The exterior materials selected are autoclaved aerated concrete
(AAC) block, batt and board siding, and metal roof. These materials are
highly recyclable and have a low-toxicity during production. The AAC is
especially essential since it can be prefabricated in a shop and then moved
into place easily to create the walls and floors of the house. This
material is made of raw natural components and gives the block a high
insulation value. All the windows in the house have been designed to
accommodate storm shutters in the event of a hurricane. The overall
palette of materials is designed to be durable not just for the current
resident but for future generations of inhabitants. The final emphasis is
on energy conservation. The use of naturally lit spaces allows for fewer
lights to be needed during the daytime. In addition to the energy
efficient heating and cooling system, the ceilings are raised up to allow for
fans in the ceilings and to circulate air. The combination of these
elements allows for the house to have minimal impact on the environment.
