The document discusses a proposed house design called the Succulent House that addresses issues of water usage and environmental sustainability. It collects and stores rainwater on the roof to meet household water demands. The roof is divided into two sections with inverted planes to direct water to storage bladders integrated into the living spaces. As the bladders fill and empty with seasonal rainfall patterns, they alter the form and atmosphere of the interior spaces. The design aims to integrate natural water cycles into daily life while reducing usage of municipal water systems.

The objective of this thesis, which was presented through floorplans, sections, elevations, and renderings, was to see how incorporating retrofitting into downtown Greensboro, NC would bring economic growth and development through architectural redevelopment. By taking an existing building and changing its function from retail/residential to commercial/ residential, the building would combine Greensboro’s flourishing arts culture and surrounding educational institutions.

Reducing the Regions’ Footprint: options for reducing the region’s carbon and ecological footprints while we continue to grow and consume
The presentation by Steve Dumez, FAIA, Design Director for Eskew+Dumez+Ripple architects based in New Orleans, reviews the history and key issues of Sustainable Design within the building industry. In addition, the overall cost and environmental impact of LEED-certified building is broken down by rating and long term benefit.
3. Crisis of Identity
The contemporary American house is experiencing a deep-
ening crisis of identity in this era of growing environmen-
talism. This identity crisis began nearly fifty years ago with
the end of the Case Study House program and the rapid ac-
celeration of suburbanization. The discipline of architecture
never regained its footing in the context of American hous-
ing as housing became a product, subject to the efficien-
cies and economics of mass manufacture. The impact of
suburban sprawl on energy, water and transportation infra-
structure was largely overlooked until its geographic con-
sequences were firmly entrenched. The widespread growth
of environmentalism has done little to assert a new identity
for the American house. Whether produced individually
or en masse, the American house remains a mixture of old
forms, updated equipment and engineered building prod-
ucts that mimic long abandoned methods of construction
and long discarded lifestyles. This critique applies as much
to the tract home as to the dwell modern, mid-century re-
mix. Neither solution comprehensively addresses changing
societal values or contributes significantly to contemporary
design culture. An appreciable shift is underway as a new
audience of environmentally concerned citizens gathers.
While thus far this audience has embraced environmentally
friendly product upgrades and supplemental equipment,
this approach is insufficient as its impact on sustainable de-
velopment is minor and its rate of change too slow. We be-
lieve growing environmentalism should be met with design
ingenuity not product specification. A lasting contribution
to sustainable development or the discipline is impossible
when underperforming architectural and urban organiza-
tions are simply reproduced using green branded products.
Our proposal, the Succulent House, addresses the pressing
global issue of freshwater quality and supply as but one
possible force to drive design ingenuity and improve envi-
ronmental performance. Ultimately, this approach allows us
to speculate on the organizational, spatial and atmospheric
potential of water collection on the American house.
The Succulent House is sited on a prototypical urban parcel
of 50 feet by 110 feet in anticipation of continuing trends
Aerial View of Roofscape toward inner beltway reurbanization. Organizationally, the
roof area of the house is divided in two and its area maxi-
mized for water collection, storage and distribution. The in-
verted roof planes direct rainwater to storage cores around
which program is distributed. In the front of the house, stor-
age bladders cascade from the modulated ceiling above to
line the more public living spaces. In the rear, the kitchen
and master suite surround a bladder wrapped winter gar-
den. Our proposal argues that performance is not mea-
sured by quantitative methods alone. In fact, we draw on
rainwater harvesting in large part because of its impact
on the spaces we propose. Roofscape collection is experi-
enced from the interior as the space rises and falls to meet
the ceiling. The collected water is stored in bladders that
respond to changes in seasonal rainfall. Like its namesake
plant, the bladders exhibit succulence in times of increased
water supply. In times of low supply, the bladders are loose
and drapery like. As the bladders fill, the reflective surfaces
capture views of adjacent conditions in unexpected ways
optically collapsing adjacent spaces into one another. The
Succulent House alters the form and atmosphere of the
house by integrating rainwater cycles into the rhythms of
everyday domestic life.

5. City Rainfall Statistics
Bladder and catchment areas are sized according to
annual totals and seasonal variations. Climates with
significant variations, such as Los Angeles, require larger
capicities to maintain the water supply in drier months.
For each city, monthly and annual values are included.
The surpluses and shortages noted below are for the
maximum roof catchment area (2800sf). Surpluses are
directed to dry wells and allowed to filter back into local
aquifers. Shortages are supplemented by the municipal
supply. In most US cities, rainwater harvesting can meet
the total water demand of the home.
