FRESH
proposal
As we approach Fresh Hills the undulating
mounds appear to be natural elements growing from the earth. The closer we get,
however, it is clear this structure, like the mounds below it, are not native
to the recently capped Fresh Kills landfill site. Its form rests lightly on the
existing topography and creates definition across the expansive horizon. It
caresses the East mound creating a seamless integration between utility scale
energy harnessing and a program filled landscape. It creates a harmonious
relationship between earth and wind. Fresh Hills is a remedy for the typical
turbine farm that so often isolates the landscape and discourages communities
from engaging the space. The artificial landscape lifts higher at levels of
increased energy potential where more predominant wind speeds and duration
exist. It is a direct relationship between energy and land. The apparatus is
generated from the grafting of Fresh Kills windrose data onto the site,
creating a seamless exchange between the site-specific data and the structure
used to harness that information. The project is site specific, but the concept
provides global versatility.The apparatus
supports the wind turbines while also acting as a buffer that redirects and
dissipates airflow towards the turbines vortex. The expansive surface area at
the mouth of the mounds helps funnel wind towards the turbine and takes
advantage of the fluid dynamic nature of airflow. The structure guides the
airflow creating a low-pressure system on the other side of the mounds
resulting in a pastoral central plaza. As if standing at the eye of a storm,
the central hub becomes a place to gather, reflect, play, and explore. At the
same time, the hub acts as a departure point guiding the user through its
valleys to the extending vista platforms. The platforms set up a relationship
between the user and the park as they reach out to frame the surrounding
context. As site lines extend beyond the immediate park all the way to the
Manhattan skyline, a richer meaning to the history of Fresh Kills transpires.
Fresh Hills is more than a CO2 filtering, energy generating
landscape. Fresh Hills is a beacon tuned to its specific frequency. It illustrates to the world what the future
of Fresh Kills stands for and delivers a promise for a healthier future. It is
a symbol that people will recognize, learn from, and interact with for many
years to come. FRESH
materials
The bamboo forest sits at the
centre of Fresh Hills where the native plants will not risk being damaged and
the bamboo will be shielded by the surrounding mounds. The forest will provide
an onsite maintenance solution to the skin of Fresh Hills and will reduce the
post production embodied energy of the structure in use by more than 50% as it sequesters
greenhouse gases and reduces need for transportation and manufacturing. As the bamboo skin weathers, the damaged
areas will be replaced by the on-site bamboo crop. This cyclical nature
considers the long-term future of the Fresh Hills and significantly reduces
emissions and material transportation needed in normal upkeep. The Fargesia
Rufa bamboo (a strong bamboo in winter seasons) and the Moso (a bamboo species with
the tensile strength of steel and a load-bearing capacity three times that of modern
wooden structural materials) will be planted and harvested every three
to five years. The initial supply of bamboo will be provided by Southern Bamboo
in Jackson Mississippi, while further outreach will look to local educational
institutions for involvement in the development of the Fresh Hills bamboo
forest. Due to the foundation constrictions of the site, bamboo is an ideal
material for Fresh Hills as it provides strength while resting lightly on the
recycled aluminum space frame and shallow concrete footings. The footings
remain shallow due to their extensive surface area that follows the contours of
the apparatus and rests on individual concrete pads below each turbine rack.
FRESH air
Fresh Hills will
work closely with Klaus Lackner of Columbia University to incorporate CO2
scrubbers. The scrubbers will attach to the back of the turbine rack and filter
the funneling air, working to remove 1 tonne of CO2 from it every day. The CO2
is absorbed by chemical filters and then collected via a plastic sheet which
will be housed and easily accessible by engineers and maintenance staff under
the same bamboo shell as the turbines and converters. Fresh Hills will absorb
the average annual amount of one American persons CO2 consumption every day,
and will remove 7,280 tonnes of CO2 annually.
FRESH eis : Environmental Impact Statement
Based on the Fresh Kills wind
energy feasibility study by BQ Energy LLC, we can assume that at least eight of
the twenty turbines will be operating at any point in time. If each turbine
produces an average of 36 MW annually Fresh Hills will provide an annual energy
surplus of 288 MW. According to the 2010 census, the energy consumption of an
average New York household is 610 kWh/month. Fresh Hills will then provide
enough energy to power nearly 250 homes in the New York area and could power as
many as 500 homes in the other areas of the United States. Fresh Hills will
become a think tank, promoting the sharing of ideas towards a healthier
lifestyle which will ultimately increase the average energy use and increase
the impact Fresh Hills will have on our local and global communities in the
future.
FRESH embodied energy
If we assume 0.098 tonnes of
carbon dioxide is produced per gigajoule of embodied energy, then thetotal
embodied energy for Fresh Hills will be recovered in five to six years.
