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


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


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.

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

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

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
