Case studyHow we strategically position hospitals in energy supply

referenzen

In newly planned hospitals and clinics, energy efficiency has been a matter of course on the agenda for years. It looks different with existing real estate. Energy costs make up only 5 to 10% of the total costs in clinics, but from the aspect that this saves 50%, it is worth taking a close look at potential renewals.


The challenge of continuous operation

Medical technology such as steam preparation for sterilization or ventilation machines and building technology such as fans, compressors and pumps are often set to run continuously or must be secured with emergency failure systems. In addition, there is lighting and IT infrastructure.

Here we look at intelligent control technology that smartly coordinates centrality, security and individual workloads. In connection with the exchange of energy sources, noticeable cost reductions can be achieved. In our current case, we are also examining the cost-effectiveness of replacing IT technology. With outsourced servers, energy-efficient screens or a supply of photovoltaics from the in-house clinic roof, we can improve the energy balance.


Challenge patient

Clinics usually have a high workload with individual people. The heat supply plays a major role here, which can be found on the smallest level in the patient's room. The challenge in our case is to ensure constant temperature control of the rooms, at the same time we will enable individual regulation of the room temperature by the patient and staff. We plan the general electricity and heat supply e.g. via a combined heat and power plant. In cooperation with the existing building insulation and a revision of the ventilation systems, the energy supply is completely reorganized in a multi-stage plan.


The challenge of conversion costs

To improve energy efficiency, clinics have often invested in the necessary and prescribed building insulation in recent years, but have not yet achieved any amortization on paper. Even if we rely on existing efficiency measures, we always have the holistic energy concept in mind. Contracting has proven to be the most recommended financing model for hospitals in terms of investment costs. Here we enable all necessary renewals of the energy infrastructure and finance ourselves from the saved costs. A win for all sides.

particularities

Medical technology and building technology such as sterilization, ventilation machines, ventilation and compressors are energy guzzlers in the permanently occupied clinics. We find the weak points: too high internal temperatures, poorly controlled heating phases, low efficiencies of existing systems, oversizing or losses in ventilation and heat transport.
