Trade-off Software

• Possesses the same advantages as the Integrated Statistical-Budgeting System.
• It is the first software of its type to be developed.
• Enables a real trade-off between different construction systems, incorporating financial and economic information of the sector or country of application.
• Extreme flexibility - can also be applied for high cost projects, be they housing or public buildings.
• Valid for any geographic and economic context.

The three software packages are currently being tested and refined by organisations and technicians who work with low-cost housing, and will thereafter be distributed worldwide.

The next steps will be the incorporation of land and infrastructure costs in the computerised evaluation process, the creation of a more sustainable financial options like a International Guarantee Fund to facilitate the discussion of housing and sustainable economic policies.

In order to establish a source of information that promotes awareness and understanding of the habitat issues on the world-wide level we recommend the creation of a Internet guide that provides current information on housing, water and sanitation, and low-cost construction technologies throughout the world.

HOME, The Housing guide may offer information about the aspects of housing on five continents.

TECHNO, Techno may offers information about low-cost housing technologies for the construction of habitat throughout the world.

INFO, The world water guide may offers information about the aspects of water throughout the world.
