The relative fungal resistance of four pairs of green Received in revised form building materials and their conventional analogs was assessed. An artificial inoculation protocol was 16 November 2009 used to investigate the effects of external nutrient levels, host material, and spore levels on the Accepted 17 November 2009 Available online 24 December 2009 susceptibility of building materials to Aspergillus niger. Also, a natural inoculation protocol was utilized to evaluate the resistance of the building materials to colonization by common indoor fungi. Increasing spore levels and the presence of external nutrients promoted the growth of A. niger
