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 1990 s. • 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
