Improvement in electrical efficiency and indoor climate in hospitals - Boraas Hospital; Eleffektivisering och foerbaettring av inneklimat i sjukhus - Boraas Lasarett

Abstract

A study was carried out in Boraas hospital with the aim to improve the indoor climate /(thermal comfort and indoor air quality) and reduce the use of electricity of fans to 2.0 kWh/m{sup 3}/s and lighting to 10 W/m{sup 2}. The indoor climate was examined using questionnaires and one-time tests. The status of the HVAC equipment was determined by one-time tests. Operating strategies for ventilation and lighting were documented. The total energy use and the energy use of individual components were determined. The main problems concerning the indoor climate were; high indoor temperatures, unbalanced air flows, noise and odours. The problems were often caused by changes in the use of premises. Three main observations were made concerning the HVAC equipment: inadequate operating analysis, complicated systems and new electrical equipment. The electrical savings potential for four buildings has been estimated to be 2040 MWh/year or 28 kWh/(m{sup 2} and year). The measures already carried out and the ones recommended to be carried out include the following areas: ventilation, heat recovery, lighting, transformers, cooling equipment and restaurant kitchen equipment. General measures for the entire hospital include the following areas: lighting in changing- rooms and culverts, transformers and PC screen switch off. The  More>>

General measures for the entire hospital include the following areas: lighting in changing- rooms and culverts, transformers and PC screen switch off. The electrical savings potential for these measures is 515 MWh/year. This study has shown that there is a large potential for improvement in the indoor climate and savings in electricity and district heating. Many measures result in important savings without requiring any investment apart from a thorough analysis. Many of these measures originate from a discovered indoor climate problem. 9 refs, 30 tabs}
