 When it comes to implementing the Passive House concept, a few special aspects of hospitals must be taken into consideration, including areas with sensitive hygiene requirements, elevated comfort requirements for recovering patients and the elderly, the wide range of various energy applications, and processes that give off great amounts of waste heat within the given area. \\ When it comes to implementing the Passive House concept, a few special aspects of hospitals must be taken into consideration, including areas with sensitive hygiene requirements, elevated comfort requirements for recovering patients and the elderly, the wide range of various energy applications, and processes that give off great amounts of waste heat within the given area. \\
  
-An analysis of guidelines shows that the use of tried and tested energy-saving technologies faces no obstacles in principle. Indeed, hygiene and energy efforts sometimes complement each other. High-quality insulation on potable water lines and optimized taps (in accordance with RKI 1) used only where water is frequently needed reduce the risk of Legionella's disease even as it lowers distribution losses in drinking water lines. If there are special requirements for areas where hygiene is of utmost importance, such as operating rooms, the solutions must be adjusted accordingly (see [[planning:non-residential_passive_house_buildings:ph_hospitals:baseline_study_-_implementing_the_passive_house_concept_in_hospitals#references|[Bräunlich 2014]]]). New concepts and approaches should always be coordinated with hygiene experts and hospital management as early in the process as possible. \\+An analysis of guidelines shows that the use of tried and tested energy-saving technologies faces no obstacles in principle.

-In rooms where medical care is provided, the greatest comfort is at room temperatures between 22 and 23 °C. For patients not wearing a lot (such as when they are washed in bed), room temperatures should be higher. In addition, the wide range of energy applications depends on the type of clinic. The study [[http://www.passiv.de/downloads/05_krankenhaus_grundlagenstudie.pdf|"Grundlagenstudie zur Umsetzung des Passivhauskonzept in Krankenhäusern" ("Baseline study on implementing the Passive House concept in hospitals")]] investigates those most relevant for energy. \\+In rooms where medical care is provided, the greatest comfort is at room temperatures between 22 and 23 °C.

 Often, the question is whether efforts to reduce heat demand are worthwhile if there is so much waste heat from processes within the hospital anyway. A closer analysis of processes that use low-temperature waste heat shows that the additional processes needed to recover that heat would reduce the benefits, in terms of primary energy, to just a fraction. The use of waste heat from inefficient processes and devices is a good idea and should be investigated, but not before the processes producing the waste heat in the first place have been optimized. \\ Often, the question is whether efforts to reduce heat demand are worthwhile if there is so much waste heat from processes within the hospital anyway.

-Hospitals are generally large, compact buildings. The study [[http://www.passiv.de/downloads/05_krankenhaus_grundlagenstudie.pdf|"Grundlagenstudie zur Umsetzung des Passivhauskonzept in Krankenhäusern" ("Baseline study on implementing the Passive House concept in hospitals")]] shows that the use of efficient technologies can, with reasonable effort, reduce heating demand to 15 kWh/(m²a) even though target indoor temperatures and air exchange rates are greater than in other buildings. \\+Hospitals are generally large, compact buildings.

 As in other Passive House buildings, good insulation means that the type of heat distribution does not matter much. Still, for various reasons, it is more practical to use surface heating systems in hospitals so that ventilation and heat run separately. Synergies can occur, for instance, when radiators are used for both heating and cooling. \\ As in other Passive House buildings, good insulation means that the type of heat distribution does not matter much.

 In addition, there are no proper energy demand labels for many hospital devices. Even if energy-efficient appliances are to be used, it is almost impossible to compare products and specify energy quality in requests for proposals – even for medical refrigerators. Complicated certification procedures for medical devices also slow down the optimization of devices. \\ In addition, there are no proper energy demand labels for many hospital devices.
