There are 25 different principles that the BBE(The New Zealand Building Biology & Ecology Institute) uses as its guidelines:

Ecological Principles:
1. Building materials should be as much as possible from renewable or non-depletable resources, be recyclable and durable;
2. Building materials should not contribute to environmental problems in their production, installation, demolition and disposal;
3. Building materials are best sourced locally to avoid excessive transportation;
4. Construction should minimize waste and unnecessary packaging;
5. Building design should consider efficient energy use and the use of renewable and self-generated energy sources;
6. Building design should consider efficient water use and environmentally friendly and self-sufficient waste water disposal;
7. The landscape design around a building needs to consider principles of sustainable and environmentally friendly use.

Biological Principles:

8. Building materials should be as much as possible of natural origin;
9. Building materials need to be of low toxicity, non radioactive, and not outgas harmful chemicals;
10. Building materials need to allow air diffusion and create a breathing third skin, thus regulating the humidity of the indoor environment and filtering and neutralizing air pollutants;
11. The indoor air temperature should aim to be within the optimum range for the health of the occupants;
12. The indoor environment should not promote, accumulate or circulate harmful vapours, particles, radioactivity, bacteria, viruses and fungi;
13. Building design should consider principles of natural heating and ventilation;
14. Buildings need to be adequately insulated against unwanted noise, and use natural light spectrum lighting;
15. Building design should consider the principles of electrobiology – to create an environment that does not change natural ionization, natural magnetic fields and beneficial cosmic and terrestrial radiation, and minimizes technical electro-magnetic interference;
16. Building design should consider site placement to avoid harmful earth radiation;
17. Building design should consider ergonomics;

Spiritual and Aesthetic Principles:

18. Colour used appropriately will promote the psychological well being of the occupants;
19. The building design should consider principles of harmony and proportion;
20. The design and building process needs to be a holistic approach and consider both eastern and western spiritual philosophies;
21. The building design should have soul and be a creative expression of its occupants;

Social and Community Principles:
22. The design of a building should foster healthy family and community relationships;
23. Buildings are best designed to complement or reflect the local character of the community;
24. Housing developments should be planned to be away from major traffic routes and centers of industry;
25. Commercial and housing developments should be socially responsible.

The Institut fűr Baubiologie und Okologie (IBO) was originally established in 1970 by Prof. Dr. Anton Schneider in Germany and now has affiliated offices in other parts of Europe, UK, USA, Canada, Australia and NZ
The New Zealand Building Biology & Ecology Institute (BBE) provides information on how buildings affect the health of people and the environment, and ways of building healthier and more sustainable homes . It promotes the Principles of Ecological Building & Designwith publications, workshops and courses, seminars and research.
