Design & Idea of building
Architect’s idea
“ Was not only to make an Academy building
but a building with a feel of Nature and Life in itself”

Materials Used
California Academy of Sciences facts and figures:
• 90% of all demolition materials were recycled
• 32,000 tons of soil from foundation excavation applied to
dune restoration projects in San Francisco
• 95% of all steel used is from recycled sources
• 15% fly ash (a recycled coal by-product), 35% slag in
concrete
• 50% of lumber harvested from Sustainable-yield forestry
• 68% of insulation comes from recycled blue jeans
• 30% less energy consumption than federal code
requirement

Green Roof
• Largest green roof with an area of
2.5 acres(1 Hectare)
• Approximately 1.7 million plants
in the blanket of living roof.
• The native plants will
provide habitat for a
wide variety of wildlife &
Biodiversity

• Bio degradable
boxes used
• Made from coconut
husk pre arranged
with plants .
• 50,000 trays used with 6
inches of soil in it.
• Approximately 1.7
million plants in the
living roof which are
native California plants.

Photovoltaic Cells
• 60,000 Photovoltaic were
used in canopy of
building.
• The multi-crystalline cells
are the most energy
efficient cells on the
market, achieving at least
20% more efficiency
compared to others.
• supply almost 213,000
kWh of clean energy per
year (at least 10% of the
Academy’s energy needs).
• And prevent the release of
more than 405,000
pounds of greenhouse gas
emissions annually.

Insulation Material Used
• Rather than using typical fiberglass or foam-based
insulation, they choose to use thick cotton batting made
from recycled blue jeans as insulation material.
• This material provides an organic alternative to
formaldehyde-laden insulation materials.
• It is also safer to handle, it is more easier to work with
and doesn't require installers to wear protective clothing
or respirators..

Heat & Humidity
• An automated ventilation system takes advantage of the natural air
currents to regulate the temperature of the building.
• This building has been designed for passive ventilation.

Radiant Floor Heating
• Tubes embedded in the concrete floor will carry hot water that warms the
floor.
• It will reduce the building’s energy need by an estimated 10% annually.

Warm air rises, and escapes through skylights ventilators

Natural Lighting
• The expansive, floor-to-ceiling walls of glass will enable 90% of the building's
interior offices to use lighting from natural sources.
• The skylights are strategically placed to allow natural sunlight to reach the
living rainforest and coral reef.
• Sensor system with automated light dimming facility to reduce energy usage.

Water Efficiency
• By absorbing rainwater, the new Academy’s living roof will prevent up to
3.6 million gallons of runoff from carrying pollutants into the ecosystem
each year (about 98% of all storm water).
• Saltwater for the aquarium will be piped in from the Pacific Ocean,
minimizing the use of potable water for aquarium systems.
• Reclaimed water from the City of San Francisco will be used to flush
the toilets, reducing the use of potable water for wastewater conveyance
by 90%.
Transportation:
• Local materials and products manufactured within 500 miles of the
Academy will account for at least 20% of building materials. This reduces
transportation impacts and supports the regional economy.
