Challenge Statement “…sustainable- to ensure that it meets the needs of the present without compromising the ability of future generations to meet their own needs.” From the 1987, the United Nations, Brundtland Commission

Definition: Triple Bottom Line Promote processes to minimize environmental and social impacts maintaining economic benefits. From the 1987, the United Nations,

Triple Bottom Line Statistics
Planet: Atmospheric CO2 for October 2015: 398.29 (ppm). Causes GHG (China is the largest contributor using 40% world’s coal) Oxygen decreased 30% Pacific Ocean 1980-today. Energy (GHG), Waste, Air emissions and Waste Water People: Per USGBC People in the U.S. spend about 90% of their time indoors where the level of pollutants may be 10 times higher than outdoor levels, except China (lung cancer is leading cause of death). Neighborhood impacts, help non-profits, employee health Profit: Reduce energy and water consumption, Increase employee health (Rick Fedrizzi USGBC CEO, Greenthink)

Global Sustainable Rating Systems
USGBC LEED (Leadership in Energy and Environmental Design) rating system started in the US in 1993 evaluating building attributes to reduce energy and water use, lesser site impact, a healthy internal environment and a full building life cycle. There are 110 possible points for certification at four levels Certified (>40), Silver (>50), Gold (>60) and Platinum (>80). More than 50,000 commercial Projects have been certified. Credit criteria is based on ASHRAE standards, other US and International legislation.
Robinson Nature Center Maryland LEED NC Platinum
Global Sustainable Rating Systems
Canada Green Building Council (CaGBC) created in 2003 to expand green building in Canada. CaGBC is a member of the World Green Building Council and is dedicated to promoting LEED rating system.
Toronto Pan Am Sports Centre LEED NC Gold
Global Sustainable Rating Systems BREEAM (Building Research Establishment Environmental Assessment Method) started in the UK in 1990 and has certified over 16,000 projects since 1998. There are 27 credits Available. Trained assessors evaluate the evidence against the credit and then report the Decision to BRE, who validate and issue the certificate. Credits are based on UK and European legislation.
London’s One Embankment Place Outstanding
Global Sustainable Rating Systems DGNB (Deutsche Gesellschaft fur Nachaltiges Bauren or German Sustainable Building Council) founded 2008 in Germany to focus on a holistic approach assessing the entire lifecycle of the building. This includes evaluation of about 50 criteria including environmental, economic, technological and work processes (organizational). There are three possible achievement levels for certificates in bronze, silver, and gold. Stuttgart: Certification for Sustainable Building awarded a category Silver by DGNB
Global Sustainable Rating Systems
China Three Star System (GBEL-Green Building Evaluation Labeling) • credits based for NEW residential and public buildings. • Developed in 2006 for three different certification levels • Different from LEED in that it includes “Operations and
Management” as one of the seven category groups (Land, Energy, Water, Materials, IEQ, O&M, Preference).
MOHURD: (Ministry of Housing and Urban-Rural Development) • developed in 2008 as a building labeling program • Mandatory in regulating energy efficiency of new government-
owned and large publically owned buildings. • (MOHURD Building Energy Label) certifies the Star rating.

Canadian Green Building Council
Online questionnaire-‐based approach, improvements, then verified by third party BREEAM assessor (Building Research Establishment)
Client works with DGNB auditor (third party) for project registration and document submission.
Formal Examination, Expert committee evaluation, and public scrutiny. Wait one year for energy .
Same asUSGBCEnergy efficiency is based on modeling. Compares to ASHRAE or local standards
Building LCA to determine building performance and efficiency of technology
Collection of absolute energy data at two different times: inspection (thoretical) and 1 year operational (measured). Compare to Chinese national standard.
Same asUSGBCRequires feasibility stuyd for using local low or zero carbon enregy sources.
Based in LCA of a building and used materials: performance
Exceed 5% Renewable of total energy consumption (today the largest investor of renewable energy)
Same asUSGBCNo Asbestos and encourages Natural ventilation (WHO guidelines for air quality)
Focus on user comfort and wellbeing of occupant (sociocultural) VOC emission criteria Installation of IAQ monitoring device
Same asUSGBC Discourages use of refrigerantsBased in LCA of a building and used materials Not Regulated
Same asUSGBCEvaluates material LCA and calculates a score (BREEAM Mat 01 Cal)
Based in LCA of a building and used materials
70% of material produced within 500 km and 10% of total material weight to be recycled
Same asUSGBC None Mentioned
Sociocultural: occupant space, public access, and design considerations (LCA for cos) None Mentioned

No credits for this now, yet realizes that this needs to be included.
Indoor Environmental Quality VOCs
Materials & Resources Chemicals
GHG
Prohibits smoking on inside of buildings. Ventilation meets minimum ASHRAE 62.1
Challenges • Not enough sustainable products (low VOCs hazards vs risk) • Lack of technical staff that are qualified • Higher up front costs for sustainable construction • Decrease of global use of natural resources • Population growing_ 7.3 billion • Material transparency from the supply chains • China and US consume 39% of the world’s energy and contribute to the
world’s highest carbon dioxide emissions (EPA, 2009)

What’s Next? (GreenBuild 2015) • Transport- oriented development gains • European Commission stated that by 2020 buildings will be zero energy use • China wants 100 smart cities by 2040 to decrease carbon emissions • Cities will have renewable energy • Cities will focus more on people • Focus more on climate change • Corporate Social Responsibility • GBCI will introduce WELL Building
Standard and CaGBC will promote this
15
In Conclusion • Reduce climate Warming • Chemical Transparency • Reduce energy use and GHG • Collaborate with industry • Resources are everywhere
