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)

Methods to reduce carbon footprint 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
