25 Guiding Principles of Building Biology

Building biology is about creating healthy, beautiful, and sustainable buildings in ecologically sound and socially connected communities.  In the selection of materials and the design of living environments, ecological, economic, and social aspects are considered.

In reality, all criteria may not always be met.  The goal therefore is to optimise each criterion within an indivdual’s framework of feasibility.

Healthy indoor air

  • Supply sufficient fresh air and reduce air pollutants and irritants
  • Avoid exposure to toxic molds, yeasts and bacteria as well as dust and allergens
  • Use materials with a pleasant or neutral smell
  • Minimise exposure to electromagnetic fields and wireless radiation
  • Use natural, non-toxic materials with the least amount of radioactivity

Thermal and acoustic comfort

  • Strive for a well-balanced ratio between thermal insulation and heat retention as well as indoor surface and air temperatures
  • Use humidity-buffering materials
  • Keep the moisture content of new construction as low as possible
  • Prefer radiant heat for heating
  • Optimise rom acoustics and control noise, including infrasound

Human-based design

  • Take harmonic proportion and form into consideration
  • Nurture the sesory perceptions of sight, hearing, smell and touch
  • Maximise daylighting and choose flicker-free lighting sources and colour schemes that closely match natural light
  • Base interior and furniture design on physiological and ergonomic findings
  • Promote regional building traditions and craftmanship

Sustainable environmental performance

  • Minimise energy consumption and renewable energy
  • Avoid cauding environmental harm when building new or renovating
  • Conserve natural resources and protect plants and animals
  • Choose materials and life cycles with the best environmental peformance, favouring regional building materials
  • Provide the best possible quality of drinking water

Socially connected and ecologically sound communities

  • Design the infrastructure for well-balanced mixed use: short distances to work, shopping, schools, public transit, essesntial services, and recreation
  • Create a living environment that meets human needs and protects the environment
  • Provide sufficient green space in rural and urban residential areas
  • Strengthen regional and local supply networks as well as self-sufficiency
  • Select building sites that are located away from sources of contamination, radiation, pollutants, and noise
