The hospital environment, studied according to the parameters of microclimate, natural and artificial lighting and acoustic regime, is a factor with an effect on the disposition and healing process. Concrete data are presented, suggesting some failures in the micro-climate kept in the hospital premises studied and substantial unfavourable discrepancies in the existing standardization and the present conditions of stay. The artificial illumination is considerably diminished--20-70 lx, at a norm of 300 lx. The windows proved to be unnecessarily large, guaranteeing increased penetration of natural light but hence - creating conditions for overheating (cooling resp.) - at at a norm 1:5 to 1:4, the established light coefficient is 1:3 up to 1:2. The acoustic regime showed also some great deviations towards the increase of noise levels - at a norm of 35 dB A, the established levels are within the limits of 38 to 72 dB A. The hospital environment is obvious to need some changes that would have a favourable effect only with a strict adherence to the hygienic standardization in the course of design and building.
