  1. SBCI Common Carbon Metric SBCI – Sustainable Building and Climate Initiative Brazilian Sustainable Building Council Marcelo Vespoli Takaoka

  2. Why buildings? Source: Common Carbon Metric for measure energy use and GHG emissions from building operations UNEP SBCI report Building sector that represents 40% of the world’s energy consumption and related 1/3rd of global greenhouse gas (GHG) emissions Energy consumption in both new and existing buildings could be cut by an estimated 30-50% by 2020 A Common Carbon Metric – provides the foundation for accurate performance baselines to be drawn, national targets set, and carbon traded on a level playing field

  3. What is measured? Source: Common Carbon Metric for measure energy use and GHG emissions from building operations UNEP SBCI report • Focus • the building’s operational phase accounts for 80-90% of emissions resulting from energy use mainly for heating, cooling, ventilation, lighting and appliances. • Unit • The actual reporting is done in weight of carbon dioxide equivalent (kgCO2e) emitted per square meter per year = kgCO2e/m2/year (by building type and by climate region)

  4. Objectives Source: Common Carbon Metric for measure energy use and GHG emissions from building operations UNEP SBCI report Establish a system of measurable, reportable, and verifiable (MRV) indicators Support policy-making to reduce GHG Provide a framework for how to measure emission reduction for carbon credit and other emission reduction mechanisms

  5. The common sense • Work on GHG reduction in buildings can significant reduce the LCCA (Life Cycle Cost Analysis) • This reduction can be share by the stakeholders • This reduction can improve more finance capacity for the owners • This reduction can prevent building premature obsolescence • This reduction can give more confidence to the finance agent • This reduction can help Climate Change

  6. How to work on GHG reduction in buildings • Leadership team characteristics to change BAU • Leadership (with a multidisciplinary team) • Strong network • Strong brands • Confidence / trust • Knowledge (technological, social and environmental) • Time to dedicate (commitment)

  7. Innovation aspects • Systemic vision • Reflexive openness • New mental models • Confidence / trust • Share vision • Stimulant environment (good place to create)

  8. The five dimensions of sustainability Society Time Infrastructure Environmental Knowledge

  9. The five dimensions of sustainability and his interrelations Society Vitality - wealthy Economic Vitality – wealthy Economic evolution Time evolution evolution Vitality – wealthy Economic Infrastructure Environmental Knowledge

  10. Stakeholders and their main wishes • Environmentalists • City government • Energy supply companies • User and Owners • Real Estate Industry • Service providers • Financial Agents • Workers • GHG reduction • Votes/make people happy • Increase results/profit • Cost reduction • Increase results/profit • Increase remuneration • Increase finance/profit • Increase jobs and salary (green jobs)

  11. Recommendations Translate GHG reduction for environmentalists to the stakeholders main wishes Include kgCO2e/per occupant/year
