New tools will be developed for cross-correlation with extensive archival resources, producing well-characterised multi-wavelength data in the form of spectral energy distributions for large sets of objects.
This combines with the ever-changing solar spectrum to produce dynamically variable spectral energy distributions that ultimately enter a building and contribute to its thermal load.
This is really the first direct determination of spectral energy distributions and redshifts ever," says lead author Jos de Bruijne, a member of the Astrophysics Division of the European Space Agency (ESA) in Noordwijk, the Netherlands.
