UNITED STATES GREEN BUILDING COUNCIL (USGBC)
HEADQUARTERS, WASHINGTON D.C. (U.S.)
PROJECT TEAM
ARCHITECT : Perkins + Will
COMPLETED : Early 2007
SITE AREA : 73,770 Sq. Ft.

It is a private membership-based non-profit organization that promotes sustainability in
building design, construction, and operation.
It is best known for its development of the Leadership in Energy and Environmental
Design (LEED) green building rating systems and its annual Green build International
Conference and Expo, the world’s largest conference and expo dedicated to green
building.
As the creator of the LEED rating system for sustainable buildings, USGBC initiated the
design of a new national headquarters that exemplifies best practices. The office space was
designed to offer 30% better air quality, save 40% more water, and use less than half
the energy of a typical comparable office space.
The project achieved a certification level of Platinum under the LEED for
Commercial Interiors rating system.

LIGHTING CONTROL CAPABILITIES

LIGHTING CONTROL CAPABILITIES
1. Accent Light: Translucent images
of nature glow with backlight
from the ambient lighting and
daylight, providing brightness and
visual interest with no additional
lighting.
2. Task Light: LED task lights at
each workstation provide
individualized lighting control.
- 6 watts - 75 Foot candles
- Fully adjustable and dimmable.
3. Ambient Light: Illuminating the
bright white ceiling creates a
bright workspace with soft, low-
glare light. The direct, downward
light provides brightness and
clarity to the workstations.
- 25-30 Foot candles on desks
- 0.45 Watts/Sq. Ft.
4. Daylight: Light colored carpet
around the perimeter reflects
sunlight to the ceiling, providing a
soft brightness to the open offices.

input from a photo sensor to maintain 25 foot candles on the desktops.
• Lighting Control Partitioning - The large Conference Rooms have retractable
partition walls to divide the space into two smaller conference rooms. Two scene
controllers in each Conference Room offer 3-way lighting control when the partition
wall is open, and divided lighting control when the partition wall is closed.

LIGHTING ENERGY USE

• Lighting Scene Control - Eight lighting
presets in the Lobby provide a variety of
bright and dim lighting scenes, and two
kinetic lighting shows.
• Occupancy Sensors - Occupancy
sensors are only activated at night to
ensure that the lobby remains a light and
inviting space during business hours.
LIGHTING CONTROL CAPABILITIES – RECEPTION AND LOBBY
Front Lobby
• Kinetic Lighting Shows - For evening hospitality events, the touch of a button
activates a calming kinetic rhythm of light and dim. Each luminaire is dimmed
independently and two lighting shows can be activated from the scene control station.
One show is a random pattern of lightening and dimming and the second show is a
wave of light that travels across the lobby.

• Lobby Square-Footage: 3,800 SF
LIGHTING CONTROL CAPABILITIES – RECEPTION AND LOBBY
LIGHTING ENERGY USE

• Occupancy Sensors –
During daylight hours – manually
During night hours – Auto on / off
• Daylight Dimming - When daylight
dimming is activated, the dimmers
respond to input from a photo sensor to
maintain 25 foot candles on the desktops.
LIGHTING CONTROL CAPABILITIES – CAFE AND KITCHEN
Kitchen
• Wall Switches - During the day, the wall switch must be turned on manually to
encourage users to keep the lights turned off when there is enough daylight. Turning
the lights on activates daylight dimming to provide the right amount of light. For
those who might need more light, the daylight dimming can be overridden by pushing
and holding the top button on the switch.

• Lobby Square-Footage: 1,950 SF
• Actual Energy consumption : 450 kWh/yr (80% below)

water is recycled.
WATER USES PRACTICES

• Implementation of Zero waste practices.
• Waste segregation at source where bio degradable waste processed in Organic Waste
Converter on site system and non-biodegradable waste processed through approved
and certified recycling vendors.
• Total organic waste generated from the campus during last year was 19,000 kg.
• Generated organic manure used for landscaping.

WASTE MANAGEMENT PRACTICES

• Regional Material : Around 80% of regional materials (within a radius of 800 km)
are used in this project.
• Recycle Content : Products with high recycle content are used, which measure to
about 13.26% of the total value of the materials in the project.
• Rapidly Renewable Material : Around 10% of rapidly renewable material eg.
bamboo flooring and furniture used.
SUSTAINABLE MATERIAL USAGE

• CO2 sensors in densely occupied spaces.
• CO2 sensors at parking.
• HVAC system designed for 30% higher ventilation rates than regular building.
• Use of low volatile emitting adhesives, sealants, paints, carpet and composite wood
products.
• The entire Campus is a NO SMOKING zone for overall health benefits and
environmental quality improvement.
ENVIRONMENTAL QUALITY

• Green Design Education –through defined green awareness signage, Wind Gallery
and open door policy for visitors on defined days
• Green Housekeeping - green housekeeping products and process are practiced
• Designed communication through customized and commissioned artworks with
themes like motivation, sustainability, vision and team work.
• All systems are controlled and monitored with the centralized Integrated Building
Management System (IBMS).
SUSTAINABILITY PRACTICES

• Solar photovoltaic panels form the
roof of the atrium of the learning
centre, generating green power.
• All workstations are equipped with
task lighting which is governed by
motion sensors turning.

• Reflective pools not only connect
the campus but also create a micro
environment in the campus, cooling
the air ground.
• 100% rainwater is harvested. 100% of
grey water is recycled via on-site
sewage treatment plant into flushing,
air-cooling and landscaping systems.

PRACTICES TO REDUCE AIR POLLUTION DURING CONSTRUCTION
• Cover and Enclosure.
• Awareness Programmes.
• NO SMOKING policy on site.
• Water Spraying.
