Evolves over
time
Comprehensive &
National
 Nationally accepted benchmark
for the design & construction
 The tool needed to measure
impact and improve the buildings’
performance
 Promotes an integrated, systems
oriented approach to high-
performance design and
construction
 Evolved since 1998 to more
accurately represent emerging
green building technologies
 Proposals to modify the LEED
standards offered and publicly
reviewed by USGBC's member
organizations

7. Who & What Can Be LEED?
Buildings Certified
Professionals Accredited
LEED- History
Over 10 Years in Development
Available to the Public in March of
2000
Initially 1 Program (for New
Construction only)
Now 7 Different LEED Rating
Programs

8. LEED Rating system

9. How does LEED work?
 Projects earn points to satisfy green building requirements.
 The number of points the project earns determines its level of LEED
certification.
To earn LEED certification,
 A project must earn a minimum 40 points on a 110-point LEED rating
system scale.
 Homes must earn a minimum of 45 points on a 136-point scale.
40- 49 50- 59 60- 79 80+

10. How does LEED work?

11. LEED Process
 LEED needs to be integrated into the design process
 Requires buy-in from entire team
 Can be accomplished with any delivery method

quality and access to daylight and
views
Innovation & Design
address sustainable building
expertise as well as design
measures not covered under
the five LEED credit
categories.

17. Innovation & Design address
sustainable building expertise
Location & Linkages promotes
walkable neighborhoods and
access to efficient transportation
options and open space.
Sustainable sites
credits encourage strategies
that minimize the impact on
ecosystems and water
resources.
Other LEED Categories
Water Efficiency

Benefits of LEED

25. 1. LEED is difficult and expensive for individual homeowners and
smaller non commercial projects.
2. LEED ignores context and performance.
3. The closer LEED gets to becoming a mandate, the more blindly it will
be followed

35. GOALS AND SUCCESSES
• To make the new office sophisticated and
advanced green building design and
technology
• Set an example for their membership and the
public, but also to demonstrate what is
possible
Increased productivity due to day lighting, good air
quality, design innovation, integrated design
process, waste reduction and avoidance
• Greatest success - day lighting
Remarkable day lighting, high-performance lighting
system achieves lighting power densities among the
best in the industry
Indoor office environment

36. STRATEGIES
•An electronic window shade system operates to maximize good daylight
and minimize glare.
•Walls, ceilings and workstation panels are colored white to reflect as much
light as possible.
•Eco-corridor features a lighter perimeter carpeting along the window line
which acts as a light shelf, reflecting natural light back into the space

37. STRATEGIES
•With lighting controls set to 80% maximum output,
lighting power density is 54% below the ASHRAE
standard. With so much daylight streaming in, use
of overhead lights reduced
•Biophilic strategies, those connecting staff to
nature, was to provide views of the outdoors from a
seated position, and 97% of all regularly occupied
spaces have a direct sightline to the outdoors.
•Energy use in space is monitored, including
energy used for lighting, to ensure we leverage
design efficiencies and systems are operating in
sync.
Overhead lighting

38. PROCESS
• Space layout, windows, HVAC, lighting, and
furniture selection and finishes
•Interior as transparent as possible - low partition
heights and interior glass features
•Reduced the amount of air conditioning load in the
summer
• Innovative linear diffusers that would automatically
deliver the supply air downward in the heating mode in
the winter months and pivot the air horizontally while in
cooling mode. This new technology significantly removes
the thermal downdraft
•Water wall which provides cooling and dehumidification

39. •8’ between the glass and the first workstation on the south face – eco-
corridor
•Daylight-responsive sensors dim light fixtures if adequate natural
light is available; spaces are only illuminated if they need to be.
•Occupancy sensors to control light fixtures – turns off light
automatically when not in use
•Thermostats used to maintain precise temperature control - regain
proper temperature quickly
