differentiator
Who is leading the
movement
 Corporate America
 Government – Federal and Local
 Higher Education
How is sustainability
demonstrated
 LEED Growth

Setting the Stage:
The Greening of Corporate America
Stage
Description
Stage 1
Green not part of the company mission
Stage 2
Green enters into the company mission
as it is legally required
Stage 3
The company considers the proactive
application of Green to be consistent with
the profit mission
Stage 4
The company transforms into a Green
organization. Green is viewed more as an
opportunity than a cost
Stage 5
The company approaches business as a
holistic, restorative company
Key Attitudes
View Environmental
Initiatives as Costs
Sustainability can
save money
Sustainability part of
corporate strategy

4 Levels of Certification
LEED is a way to define and
measure “green buildings,”
providing third-party verification
that measures how well a
building performs across the
metrics that matter most:

Sustainable Sites Overview
 Sustainable Sites goals
- Develop only appropriate sites
- Reuse existing buildings and/or sites
- Protect natural and agricultural areas
- Reduce emissions associated with automobile use
- Protect and/or restore sites
- Manage storm-water runoff
- Reduce heat-island effect & light pollution
 Building’s impact on ecosystems
- Greenfield or previously undeveloped sites consume
land
- Development must be sensitive to impacting agricultural
land and wildlife habitat
- Sedimentation due to erosion impacts waterway
navigation and aquatic live
- External lighting causes light pollution

Why Materials and Resources?
Some Facts:
 Buildings account for 40% of raw materials use
and 30% of waste output
 US residents, business, institutions produced
251 million tons of waste in 2006 (4.6 lbs. per
person, +25% since 1980)

Intent
Have in place a system for continuous tracking and
optimization of systems that regulate indoor comfort and
conditions (air temperature, humidity, air speed and radiant
temperature) in occupied spaces
Temperature and
Humidity Trend Report:
20% floor area
Siemens Solution to meet Requirements
 Develop a complete inventory of all sensors located in the
facility, and install additional sensors as necessary
 Monitor air temperature and humidity in occupied spaces
(15 minute intervals)
 Implement alarm procedures
 Provide supporting Preventive Maintenance
documentation for sensors
 Periodic testing of air speed and radiant temperature in
occupied spaces
Temperature and
Humidity Trend Report:
20% of sensors
Case Study: Taipei 101
Key Challenges
 Tenant engagement and support
 Minimize disruptions to ongoing operations
Achieving LEED Certification
 Key drivers for certification: corporate social
responsibility, attract and retain tenants, reduce
lifecycle cost
Key Facts
 Over 2 million gross square
feet of floor area; over 10,000
people in the building
 Earned LEED EB Platinum
certification in 2011; World’s
tallest Green Building
 30% more energy efficient than
similar buildings
 Automation system controls and monitors over 30,000
points throughout the building
 Asia’s largest air distribution system: 3,400 VAV boxes
throughout the building to allow individual tenant
control
 Achieved ~10% annual reduction in electrical use,
water consumption, waste
 $700,000 in annual energy savings
 Energy efficiency measures: lighting retrofits, BAS
optimization, chiller plant optimization
The Critical role of the BAS
Across the Building Lifecycle
BAS Impact
 Backbone for an efficient infrastructure
 Ensures implementation and application of
energy optimization strategies
 Provides critical alarming and information
management tools
 Can support over ½ of LEED points in New
Construction and Existing Buildings
