NAS EnerBuild RTD, Budapest Workshop, 24&25 January 2003
Background
Daylighting:
What we all (should) know
but do we really consider it in practice ...
Technical issues
Satisfaction of the end-user
Regulatory obligations
Individual needs and demands
Visual perception:
• quality of light
• quantity of light
• individual visual capability
Regulations, recommendations, … :
• minimum glazed area
• correction factors (actual light transmission)
• daylight factor
• spatial distribution of light
• direct insolation
• link to thermal requirements
• …..
Present situation:
• specific regulations for (day)lighting?
• demands from other regulations
Past situation:
• a standard acting as a regulation - daylighting and electric lighting
SLOVENIA
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
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
“The right to sunlight”
Sets of requirements by health inspectorates
National building law: “influence of a building on existing neighbouring buildings and people”
Direct insolation
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
…..
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
