Indoor environment in Polish hospitals is designed with the consideration of the following documents:
- Journal of Laws of 2002, No 217, item 1833: the Regulation of the Minister of Labour and Social Policy of 29 November 2002 on maximum permissible concentration and intensity of agents harmful to health in the working environment,
- Journal of Laws of 2002 No. 75, item 690 with later amendments: the Regulation of the Minister of Infrastructure of 12 April 2002 on the technical specifications for buildings and their location with later amendments,
- Journal of Laws No 31, item 158 with later amendment: the Regulation of the Minister of Health of 2 February 2011 concerning requirements that should be met in professional and sanitary aspects by premises and equipment of health care units with later amendment,
- EN 12831:2003 Heating systems in buildings. Method for calculation of the design heat load,
- Design guidelines for hospitals. Sanitary installations. Booklet 5 – Ventilation and Air-conditioning, Ed. 1984 r. (in Polish).
The above-cited documents mention the requirements for the thermal environment in patient rooms as a subtopic related to safety. Yet, there are real grounds to believe that hospital indoor air influences patients’ healing process and recovery (Huisman 2012).
The study of thermal environment in patient rooms was carried out by researchers from other countries who, subsequently, sought to translate the research findings onto indoor air quality in patient care units (Verheyen 2011, Short 2012, Adamu 2012, De Giuli 2013, Thiel 2014, Skoog 2005, etc).
In Polish hospitals there exists no objective research which would indicate the possibility of improving indoor air quality in wards. In response to this information vacuum, we developed a project Improvement of indoor conditions for patient recovery in Polish hospitals. The project is financed by Halton Foundation Inc. It is planned to be carried out from 2016 to 2018 by the Faculty of Building Services, Hydro and Environmental Engineering from the Warsaw University of Technology.
The overarching aim of the project is to develop guidelines for indoor environment (air distribution and microclimate parameters) in patient rooms in Polish hospitals and to prepare and disseminate an advisory platform including cost-efficient and effective technical solutions that can be applied when upgrading patient rooms.
The aim of the first phase of the project (2016) is a quantitative analysis and a qualitative analysis of indoor environmental conditions in patient rooms in Polish hospitals.
