Radiation data are needed for solar resource assessment, design and
evaluation of solar systems and buildings, and solar collector testing.
As the performance of certain types of solar systems, building
components and solar collectors depends on the spectral distribution in
the ultraviolet, visible and infrared spectral range of the incoming
solar radiation and on longwave thermal radiation exchange as well, a
need was identified for improving the quantity and quality of spectral
radiation data, both broad-band and narrow-band.
Task 17, which ran
from 1 September 1991 until 31 August 1994, addressed this need by
focusing research on three types of spectral radiation data:
- Narrow-band spectral radiation data for applications to solar
and building materials;
- Broad-band spectral radiation data in the visible range (that
is, visible light) for applications to natural illumination in
- Broad-band spectral radiation data in the infrared range (that
is, long-wave radiation) for applications to the energy balance of
solar systems and buildings.
