The document presents diagrams for a sustainable housing design called the 3+1 b2 House in New Orleans. It utilizes several passive design strategies to reduce energy needs including cross ventilation through a longitudinal hallway and floor vents, stack ventilation with high ceilings and operable windows, and raised foundation to allow air circulation. Other strategies are daylighting from north-facing windows, deep overhangs, a rainwater cistern, and solar photovoltaic panels on the south-facing roof. The design is derived from traditional New Orleans "camelback" housing adapted for sustainability and alternative family living patterns.

SUSTAINABILITY DIAGRAMS
Cross-Ventilation
Longitudinal hallway pulls east-west breezes
through house. Floor vents allow cool air to enter
from below and exit through operable windows.
Stack-Ventilation
High ceilings and operable windows allow hot air
to rise and vent to exterior.
Raised Structure
Allow air to circulate under the building.
Daylighting
North facing windows allow abundant indirect
daylight while limiting heat gain.
Deep Overhangs
Reduce heat gain and provide sheltered outdoor spaces.
Rainwater Cistern
Use of pitched roofs shed water expeditiously and collect
rainwater in cistern for non-potable uses.
Photo Voltaic Panels
35 degree, south-facing camelback roof provides
+500 sq ft of solar panels.
Permeable Paving
Permeable paving surfaces for stormwater management.
Living Wall
Provides shade to parking area.
IDENTIFIABLE VERNACULAR
The 3+1 b2
House is derived from the juxtaposition of the
technological and cultural influences of current times with
the functionality of the New Orleans camelback housing
style. The 3+1 b2
House plan is asymmetrically configured
to adapt to primary and secondary family or economic
patterning. The second floor plan configuration for this
design diverges from traditional placement in the rear to
allow for ideal accommodation of alternative energy sources.
The double camelback is an ideally suited building style
to the project requirements of the MIR Phase II program,
lending to the extended family living patterns of this area
and also the benefits of economic return. Mandated site
adaptations of this style provide additional opportunities
for extended living space, secure off-street parking and
emergency refuge by lifting the living areas above base
flood elevations. Essential to the camelback housing style
is the truth that “Community begins at the front porch”.

SUSTAINABLE DESIGN
The 3+1 b2
House models the latest technology and building
planning concepts incorporating alternative energy sources,
plumbing and air conditioning systems that reduce water
and energy needs and a high-performance envelope system
that contributes to low overall power consumption. Key
sustainable design strategies will include minimizing southern
exposure fenestrations, maximizing northern exposure
daylighting, rainwater harvesting, C2C materials selections
and use of solar PV panels.
REBUILD SMART
The 3+1 b2
House follows this firm’s commitment to
community preservation, building long-lasting value in our
structures and advancement of the art of wbuilding. We
look to the community for design inspiration and cultural
reinforcement in the design of the 3+1 b2
House, facilitat-
ing comfortable, contemporary living. The use of low-cost,
durable materials and proven construction techniques
assures value to returning homeowners. The 3+1 b2
House attempts to explore new alternatives to construc-
tion efficiency in envelope design and massing simplicity.
