Purpose and origin
• Purpose is to find out how
much carbon dioxide
emissions building
produces during it’s
lifespan.
• Concept name was
developed in the 1990s.
• Number of Earths.
Scope
• The scope is changing.
• Energy efficiency is better.
• Construction phase is becoming more dominant.
• Renovating old building stock.
Methods, processes, tools
• Two phases:
• Construction phase
• Use phase
• Life cycle assessment - LCA
• Process LCA
• Input-output LCA (IO LCA)

Green building
A building is considered “green” when it
saves resources and money. In addition it
protects
human
health
and
the
environment, and creates a healthy living
space. A green building is one which is more
efficient,
economical,
healthy
and
environmentally friendly. To become green,
a building needs to use materials and
resources that are of recyclable content, it
maximizes the use of renewable energy, it
conserves water and creates a healthy
indoor air quality.
Examples
- Study of the pilot office building – Focused on building materials
