A GREENER APPLE – STEVE JOBS
Apple completely eliminated the use of CRTs in mid 2006
Apple products met both the spirit and letter of the RoHS restrictions on
cadmium, hexavalent chromium and brominated f flame retardants years
before RoHS went into effect.
Apple plans to completely eliminate the use of arsenic in all of its displays
by the end of 2008.
Apple plans to completely eliminate the use of PVC and BFRs in its
products by the end of 2008.
All the e-waste we collect in North America is processed in the U.S., and
nothing is shipped overseas for disposal.
Apple products are designed using high quality materials that are in high
demand from recyclers.

Buildings consume 40 percent of our energy and
can have life spans longer than humans.
Form and function
Curved forms increase structural stability and maximize
this reduces the amount of materials needed for
The shape is also aerodynamic, diffusing the impact of
Traditional rooftops, covered in asphalt and tar, create heat-absorbing surfaces
that contribute to the quot;urban heat islandquot; effect—higher temperatures that can
urban island effect higher
alter weather patterns and intensify smog.
A layer of ground cover on this building s roof helps to regulate temperature
protects waterproof coatings, and absorbs and cleans storm water.
Soil and Green
The western side of the building is a series of three-story atrium gardens.
The greenery brings the outdoors inside, providing a breath of nature.
Plants clean the interior air, and as leaf colors change, the building reacts
in step with natural cycles.
The th f d (
Th north façade (unseen) is clear glass covered with positively-charged
)i l l d ith iti l h d
mosses that absorb particulates of the air.
Water is recycled in the building several times over.
Greenhouses treat wastewater from sinks and bathtubs for reuse as irrigation in the
building's gardens, a process made possible when nontoxic cleaning products are used.
Cleansed by th gardens, the water can be used again as non-drinking water—for
Cl d b the d th t b d i d i ki t f
example, in toilets.
After a close study of the sun and shadows, the shape and orientation of the building are
tailored to the site.
This building faces south toward a park, so it can capture maximum sunlight, and its
irregular form allows more daylight to reach the street
Gardens circle the base, contributing to the quality of life at street level.
The southern façade, made of about 100,000 square feet of photovoltaic panels that convert
sunlight into electricity, collects enough energy to provide up to 40 percent of the building's
Costing at least 20 cents per kilowatt-hour—several times as much as coal or natural gas—
solar PV is expensive today
But the trends are good: Solar is getting cheaper, and the relative economics will improve as
more states and countries regulate th production of greenhouse gases.

The structure is built up in layers of materials that perform different functions, from
weatherproofing to insulation to transparency.
These surfaces are becoming thinner, lighter, and smarter.
Under-floor air distribution improves air quality.
Flexible communal spaces replace fixed individual stations.
Chairs and workstations are ergonomic.
Smart monitors detect the presence of people and adjust temperature, light, air, and
sound as needed
This allows individuals to control their environment.
Our tt quot;We don't heat
O motto: quot;W d 't h t or cooll ghosts.quot;h tquot;
Waste equals food
In nature, nutrients are cycled and recycled endlessly.
quot;Eco-effective designquot; seeks to mimic those cycles.
Eco effective design
All products, from building materials to furnishings, are designed to return safely to the
earth or to be reused like office chairs that can be disassembled into components and
sent back to the manufacturer to become another product.
Heating and cooling
They account for almost 30 percent of a building's energy use.
By transferring heat between the building and the earth using a system that circulates heat-
absorbing liquid through underground wells, a building can reduce energy usage.
A combined heat-and-power plant, fueled by natural gas, operates at up to 90 percent efficiency
and supplies the power that the solar panels cannot.
