RSMF =
Room Surface Maintenance Factor Depends on the environment, if it’s clean or “unclean” the reflectance factors and the cleaning intervals. LMF and RSMF can differ between the standards and guides for different countries e.g. Ljusamallen in Sweden or DS 700 in Denmark. If no specific LMF and RSMF values are defined for the project, the tables below can be used.
