- Vanke Developer - Wonderland Phase IV
This proposal provides a number of strategies
for reducing energy consumption. Like many of the buildings in the
master plan, our buildings are oriented to provide high levels of
north-south exposure to maximize shading concerns. This orientation
increases the amount of solar gain in the winter, and the high sun
angle in the summer requires only slight overhangs to counteract
the hot summer sun. Along the east and west axis, the edges are
perforated, so as to allow for natural airflow ventilation from
the east and to decrease exposure from the intense afternoon sun
from the west. Despite the north-south orientation, we have also
allowed for some east-west exposure by staggering individual units,
affording instances of localized shading and cross-ventilation.
The second major effort of the proposal seeks to address issues
of sustainability at the urban scale. In an age of increasing population
and decreasing lot sizes, it is important to address how a housing
project will responsibly meet urban demands. Urbanistically, we
propose to create lower buildings at a higher density. One notable
exception is the northern edge that requires taller buildings to
provide a barrier against noise pollution from the trains. With
a larger ground floor footprint and an increased building surface
area through the staggering effect, exposure to the outdoors for
each unit is increased. A central goal is to increase opportunities
for interaction with natural exterior conditions. This relationship
is mediated through the implementation of small, intimate courtyards.
We believe such spaces will provide more meaningful individual experiences
and personal interactions than the singular large courtyard prevalent
in the existing plans.
The goal has been to create a unique environment appropriate
to a diverse community. This is achieved by juxtaposing apartments
of different sizes and qualities within the same apartment building.
The creation of dwellings is based on an estimated daily spatial
usage. This strategy serves to promote a satisfactory balance of
factors such as privacy and comfort, thus minimizing the need for
restoration or modification. With respect to sustainable design
issues, specific attention has been paid to directional differences
within the building composition. The East Side, though sometimes
hot, exploits the primary natural airflow. The South and North sides
are more interchangeable with respect to natural ventilation issues.
Also of special consideration has been the relationship between
courtyard and non-courtyard sides of the buildings where a coupling
of unit pairs fosters a sense of both a front and backyard.
The design strategy incorporates numerous technologies
including natural ventilation at the local level and shading using
fins, overhangs, and deep balconies. Also of importance is the reduction
of noise pollution on the site. Statistically the number of trains
will not cause much discomfort unless they run primarily at night.
Minimizing the exposed areas was an important issue and has resulted
in a continuous tall building on the northern edge serving to block
noise from the rest of the site. This strategy is validated because
sound treatment is expensive and the exposed surfaces should therefore
be treated (see page 6). In addition, we intend to use solar heat
collectors on the housing units of Wonderland Phase IV. These will
help to save costs associated with heating water for kitchen, shower,
and laundry usage.
