The Leadership in Energy
and Environmental Design
(LEED) Green Building Rating
System,
Developed by the U.S.
Green Building Council
(USGBC), provides a suite of
standards for
environmentally sustainable
construction.
Started in 1998

3. What is a Green Building?
Green buildings are designed to reduce the overall
impact of the built environment on human health and the
natural environment by
• Efficiently using energy, water, and other resources
• Protecting occupant health and improving employee productivity
• Reducing waste, pollution and environmental degradation

The uncommon triangular
framing pattern (also known as
a diagrid) required 9,500 metric
tons (10,480 tons) of structural
steel – reportedly about 20%
less than a conventional steel
frame.

First green building
completed in New York City
• Floor of the atrium is paved
with heat conductive
limestone.
• Polyethylene tubing is
embedded under the floor and
filled with circulating water for
cooling in the summer and
heating in the winter.
• Rain collected on the roof is
stored in a tank in the
basement for use in the
cooling system, to irrigate
plants and for the water
sculpture in the main lobby.
• The building was constructed
using 80% recycled steel.

Atrium features escalators
which run through a 3-story
water sculpture titled
Icefall, a wide waterfall built
with thousands of glass
panels, which cools and
humidifies the lobby air.
The water element is
complemented by a 70-foot
(21.3 m) tall fresco painting
entitled Riverlines by artist
Richard Long.

LEED for New Construction
certification.
There are some unique
challenges when building a

the most prominent one
being the issue of safety.
• The Sofia Embassy building
design was based on a model
created after the dual
bombings of embassies in
Kenya and Tanzania.
• This ensured that the embassy
would incorporate the safety
features from the Standard
Embassy Design (PDF) as it
implemented green building

50. Discussion Roundup
materials
• focusing on recycling materials
• (similar or dissimilar to Romans excavating ancient sites?)
• incorporating the natural world
• (is this a modern idea? or an established idea?)
design choices made for reasons beyond aesthetics
• environment is key
thinking a great deal about interior environment
and user experience
• lighting
• (how does this relate to lighting of gothic churches?)
• new and different ways of regulating interior systems
(temperature, water)
• (how does this relate to Roman bath houses?)

51. Reflection
Can beautiful design and sustainability co-exist in a
building?
What do you think about combining new and old? For
example, the Hearst Tower being built on the facade of the
1928 building.
Do you think it’s important to think about the
environment when we build new buildings?
