Sustainable construction is not a passing fad
Membership in the U.S. Green Building Council has increased from fewer than 100 to over 18,000 in the past decade
Over 155,000 building professionals are LEED certified
Demand for “green building materials” is forecasted to grow at an accelerated rate

The Governor's Green Building Action Plan B-18-12
Highlights:
“State agencies, departments … reduce entity-wide GHG emissions by at least 10% by 2015 and 20% by 2020…”
“All new State buildings and major renovations beginning design after 2025 shall be constructed as Zero Net Energy”
New & major renovated State buildings and build-to-suit leases larger than 10,000 square feet shall obtain LEED ‘silver’ certification or higher …”

The Rise of City Standards

Sample Standards
Buildings have performance equivalent to an Energy Star rating of at least 60-75
New residential & commercial construction to exceed Title 24 energy efficiency standards
Adopt and implement local green building ordinance of program setting minimum standards
Provide incentives to private developments to meet or exceed specified standards under Build It Green, LEED, or similar

Leading by Example and Achieving Results Named World’s Greenest City by World
Green Building Council
GHG emissions nearly 12% below 1990 levels
Has surpassed international and statewide emissions target
Example: CA requires 50% construction debris be diverted from landfill (recycle/reduce); SF requires 75%
Recently established target: reduce carbon emissions to 20% below 1990 levels by year end, by 80% by 2020
Laguna Honda Hospital, the first hospital in CA to achieve LEED
Silver
The iconic Transamerica building was the first building to comply with SF’s renovation standards
The Need for Effective Measurement, Comparison and Certification
Page 12
Deliver insight and certainty
Analyze key characteristics: carbon, water, costs and waste
Measure & report alignment with standards => Carbon Disclosure Project (CDP), Global Reporting Initiatives (GRI), GHG Protocols, Architecture 2030, California standards...
Critical foundation for creating Environmental Product Declarations (EPDs)
Data delivers LEED process clarity
Provide reliable tools for effective decision making
Yields real environmental performance measures
Carbon Accounting Tool
Lifecycle Assessment
LCA
Measurement, Comparison and Certification Tools:
A Closer Look: Carbon Calculator

The executive dashboard from Climate Earth allows Central Concrete to track the key sustainability metrics that we established up front – GHG and water – both critically strategic to our long-term success.
Example: Measuring Enterprise, Supply Chain and 18,000 Product Mix Combinations

Easily understood data provides impactful information on GHG impact
Environmental Product Declarations (EPD)
Page 19
Why EPDs?
Page 20
Why Bother?
Building owners asking for EPDs
=> Must report your carbon footprint
Required by Architecture 2030
=> Building Challenge
LEED 2012
=> New credits for EPDs
=> New credits for LCA
Product Category Rules (PCPRs) are being developed
=> They will set the protocols for reporting and validating the environmental impacts in the EPD
Allows for Comparisons
