Building materials and acoustics

  • Natural and unadulterated building materials
  • With a pleasant or neutral smell and without outgassing toxins
  • Building materials with low radioactivity levels
  • Human-oriented noise and vibration protection

Indoor Environmental Quality – not just air

  • Natural regulation of indoor air humidity through humidity-buffering materials
  • Low total moisture content of a new building that dries out quickly
  • Well-balanced ratio between thermal insulation and heat retention
  • Optimal air and surface temperatures
  • Good indoor air quality through natural ventilation
  • Heating system based on radiant heat
  • Changing the natural balance of background radiation as little as possible
  • Without human-made electromagnetic and radiofrequency radiation exposure
  • Reduction of fungi, bacteria, dust and allergens as low as possible

Environment, Energy and Water

  • Minimizing energy consumption and utilizing as much renewable energy as possible
  • Building materials preferably from the local region without promoting exploitation of scarce and hazardous resources
  • Causing no environmental problems
  • Best possible drinking water quality

Spacial Design

  • Consideration of harmonic measures, proportions and shapes
  • Natural conditions of light, lighting and color
  • Application of physiological and ergonomic findings to interior and furniture design

Building Site

  • Building site without natural and human-made disturbances
  • Residential homes away from sources of emissions and noise
  • Low-density housing with sufficient green space
  • Personalized, natural, human- and family-oriented housing and settlements
  • Building without causing social burdens
