"Green Build" is an energy and environmental rating system for urban development areas and buildings with focus on use of healthy and sustainable building materials and optimisation of heat, electricity and water consumption, energy supply, indoor climate and waste treatment.

"Green Build" is divided into the following areas:

A. Methods for sustainable urban management.
B. Urban development area, incl. site, infrastructure, energy/supply and immediate environment
C. Waste management
D. Materials
E. Energy efficiency and renewable energy
F. Indoor climate conditions
G. Water

The first three of these (A, B and C) are areas where the involved city and municipality are evaluated in connection to urban management, site and waste management.

The remaining areas concern the individual building projects. Here it is especially difficult to handle and evaluate "Materials" (D) and for the moment mainly the general conditions here will be looked at (D-9). Generally the "Green Build" system gives most "points" to the solutions that one would like to encourage.

In connection to each of the above-mentioned areas it could be possible, together with the involved cities, to define different "Green Build" levels, which can be defined as a target for how important it is to have sustainable solutions introduced in the different areas.

Then it is possible for a certain city or a certain urban development area to judge which minimum demands for energy and environmental points you want to introduce, and the chosen level can then based on experiences be regulated later.

In the beginning it seems most relevant to use agreed upon "energy and environmental point" levels to ensure a documentation concerning minimum demands for a sustainable development in new urban development areas and building projects.

Generally the points are given on the basis of the following conditions:
# Outside environmental considerations
# Indoor environmental considerations
# Characteristics of materials (sensitivity of smell/particle)
# Energy to production
# Prevalence of materials and regneration
# Functional and physical suitability
# Operation and maintenance
# Social circumstances.
