Reducing CO₂ emissions and improving the environment

• Wood products store the CO₂ absorbed by growing tree
• Substantial reductions of CO₂ emissions can be achieved by substituting wood for other materials
• Wood buildings also reduce CO₂ emissions as a result of their energy-efficiency
• Life Cycle Assessment demonstrates the low environmental impact of wood buildings
• Whole Life Costing demonstrates the cost-efficiency of wood buildings

Energy-efficiency

• Japan needs increasing energy supplies
• But most energy production has an impact on the environment
• Energy-efficient buildings are part of the answer
• Wood buildings are more energy-efficient
• Wood frame buildings are easier to insulate
• Research confirms wood buildings save energy

Cost-efficiency

• Wood frame is popular world-wide
• There are many studies showing it is cost-efficient in construction and operation

Safety and durability

• Wood frame construction has superior seismic performance, even in the most severe earthquakes
• Fire safety is assured by fire-rated, finished assemblies and code-compliancy
• Different climatic conditions are taken into account to avoid issues with biological agents
• Surveys demonstrate the durability of wood buildings
• Codes and standards ensure wood buildings are constructed for durability
• Design and construction practices are backed by extensive research
