Vitamin D for planners, architects, ...

Tuesday February 28, 2012

First publication Vitamin D Wiki has seen on the subject
CLICK HERE for PDF, Published by Chief Health Officer Victoria Australia – May 2010
This publication is a good first start, includes many good points

Hopefully future versions of papers like this one will point out that:

  • Differences between UVA (suntan) and UVB (make vitamin D)
  • UVB is about 3X less in shade, and UVA is reduced even more
  • Windows do not transmit any UVB to generate vitamin D
    And that it may be that the UVA transmitted by windows uses up some of the vitamin D
  • UVB lighting is possible from special lamps inside of offices (truly full spectrum)
  • UVB reflects poorly from buildings – so not as much vitamin D at the bottom of an urban canyon
  • There is less UVB in large cities due to pollution/ozone
