WORKSHOP: The roles of wood in green building and green building effects on the forest sector of in the UNECE region.

Alison Rowles-Anobile, Special Advisor IUCN Conservation Center Green Building Project

Are ENGO’s ready to promote the use of wood as the preferred building material?

Why IUCN is Building Green

• Worldwide, buildings account for up to 40% of CO2 emissions• Buildings account for 43% of the US CO2 emissions with BRIC

countries catching up.• Greenhouse gas emissions from US buildings is equal to the

combined emissions from Japan, France and the UK. • Over the next 25 years emissions from buildings will increase faster

than in any other sector• China is building the equivalent of Japan’s total building area every

three years!• IUCN wants to:

– Encourage others to build green– Provide access to the knowledge and tools to do so – Link biodiversity conservation and sustainable construction

IUCN Conservation Center Objectives

Green Building Standards– MINERGIE-P (Switzerland)

• Low energy consumption– MINERGIE-ECO (Switzerland)

• Green construction and design– LEED: Leadership in Energy and Environmental Design

(USA) «Gold/Platinum»• Rating system that includes standards for site development,

water savings, energy efficiency, materials selection and indoor air quality.

(Only 51 Platinum Buildings worldwide – 6 outside US)

IUCN Green Building Specifications

• High Performance Energy Systems (Solar and Thermal)85% of Energy Consumption from renewable sources

• Water Efficiency (reclaimed water and storm water management)Potable water use 22% less than baseline

• Materials and Resources (minimal use of materials)CO2 reduced and recycled concrete + thermal concrete75% of the wood FSC

• High Indoor Environmental Quality (CO2 controlled air supply)passive solar with natural light throughout

Fragmented and complex

International Union for Conservation of Nature

Issues Influencing use of wood

• No common link between global standards to facilitate implementation

• Negative perception of timber use due to global deforestation and increasing climate change

• Stakeholders not united in reduce, reuse and recycle mechanism

• Public Relations efforts behind those of other materials suppliers

• Major impact on reduction of energy use by buildings in refurbishment and renovation – not new construction where wood is mostly used

• Educational efforts needed with architects, suppliers and investors

• Pricing not always favorable for FSC products

International Union for Conservation of Nature

Support ENGO mandates

• Demonstrate forest management links to bio-diversity

• Show positive impacts on water and energy consumption

• Focus on policy and legislative support for consumer incentives

• Strengthen links to global initiatives for green cities

• Build links to programmes for climate change mitigation

• Set standards for minimizing wood consumption and wasted materials

• Ensure industry standards to facilitate due diligence
