  2. Background Daylighting: What we all (should) know but do we really consider it in practice ...

  3. Technical issues Satisfaction of the end-user Regulatory obligations Individual needs and demands

  4. Visual perception: • quality of light • quantity of light • individual visual capability

  5. Regulations, recommendations, … : • minimum glazed area • correction factors (actual light transmission) • daylight factor • spatial distribution of light • direct insolation • link to thermal requirements • …..

  6. SLOVENIA • Present situation: • specific regulations for (day)lighting? • demands from other regulations • Past situation: • a standard acting as a regulation - daylighting and electric lighting

  7. Slovenian standards, regulations, … : SIST DIN 5034 (1-6) Regulation on requirements for safety and health of workers in working spaces Regulation on minimum technical requirements for residential buildings and apartments Regulation on normatives and minimum technical requirements for kindergartens Regulation on thermal protection and efficient use of energy in buildings Handbook for consultancy services in investment construction work

  8. Non-obligatory scheme: National quality mark in civil engineering - technical quality of residential buildings (ZRMK) Daylighting as an equivalent topic Definition of criteria Evaluation scheme

  9. Direct insolation “The right to sunlight” Sets of requirements by health inspectorates National building law: “influence of a building on existing neighbouring buildings and people”

  10. Design practice: No treating of daylighting issues at all Satisfying minimum requirements Consideration of individual demands In-depth analysis: visual comfort, impact on electricity use … Insolation studies …..

  11. Facts: satisfying human biological and psychological needs integral part of energy-conscious design well-balanced technical and non-technical items Needs: national regulations awareness-raising transfer into common practice
