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 Baseline study on implementing the Passive House concept in hospitals investigates those most relevant for energy. \\ |
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, | 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.

The Baseline study - 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. \\ |
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.
