In my desire to contribute to the dissemination of a hitherto forgotten aspect, I would like to share with you the 25 principles of Building Biology, published by the Building Biology Institute (USA). 

They are a set of criteria for creating healthy, nature-connected, sustainable and beautiful living environments.  They take into account ecological, economic and social aspects in the choice of materials and the design of living spaces.

THE 25 PRINCIPLES OF BUILDING

Building Biology Institute

INDOOR CLIMATE

01.- To reduce pollutants and irritants and to provide sufficient fresh air.

02.- Reduce the presence of toxic fungi, yeasts and bacteria, as well as dust and other allergens.

03.- Use materials with a neutral or pleasant odour.

04.- Minimise electromagnetic fields and high frequency waves.

05.- Prioritise radiant heat for heating.

INTERIOR AND ARCHITECTURAL DESIGN

06.- To observe harmonious proportions and shapes.

07.- Stimulate sensory perceptions: sight, hearing, smell and touch

08.- Favour lighting conditions and spectrum close to natural light and use flicker-free lamps.

09.- Consider knowledge of physiology and ergonomics.

10.- Promote local and regional building culture and craftsmanship.

ECO-SOCIAL HABITAT

11.- Design infrastructures with a balanced combination of uses: short distances to workplaces, public transport, schools, shops, etc.

12.- To favour a way of living that satisfies human needs and protects the environment.

13.- To provide sufficient green space in rural and urban residential areas

14.- To strengthen local self-reliance and the involvement of local networks and service providers

15.- Select construction sites that are not contaminated by harmful waste, sources of radiation, pollution and noise.

CONSTRUCTION MATERIALS AND EQUIPMENT

16.- Use natural, non-toxic materials with as little radioactivity as possible.

17.- Ensure a balanced ratio between thermal insulation and heat accumulation, as well as between surface temperature and indoor air temperature

18.- Use hygroscopic materials.

19.- Minimise the moisture content of new construction.

20.- Optimise the conditioning and acoustic insulation of spaces (including infrasound).

ENVIRONMENT, ENERGY AND WATER

21.- Minimise energy consumption and use renewable sources.

22.- When building or refurbishing, avoid negative impacts on the environment

23.- Conserve natural resources and protect flora and fauna.

24.- Favour local building systems, choose materials and life cycles with the best possible ecological balance

25.- To ensure the best possible quality of drinking water.
