Why buildings? • 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

What is measured?

• 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)

Objectives

• 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

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

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)

Innovation aspects

– Systemic vision– Reflexive openness– New mental models– Confidence / trust– Share vision– Stimulant environment (good place to create)
