Energy situation in German hospitals2087 hospitals with approx. 507,000 beds in Germany
Total consumption in German hospitals:approx. 12.5 M MWh / year heatingapprox. 13.9 M MWh / year electricity
Overall energy costs per year: approx. Euro 1.7 bn
Possible savings in German hospitals
By implementing optimal technical rehabilitation measures German hospitals
can save:up to 40 % on energy costsmore than Euro 600 M per year
and avoid up to 6,000,000 tons of CO2 .

How can hospitals save up to 40 % on their energy costs?
modernisation of heating and control engineering
use of a combined heat and power plant (CHP)
modernisation of the air-conditioning and ventilation systems
energy management and central building control systems
use of heat recovery
use of energy-saving lamps, electronic chokes and natural light
use of solar heat
isolation of the building face
user behaviour
Most importantly: They dont have to invent anything new!

How can the technical and financial benefits of different options be assessed?
Apply a value analysisusing the
The energy potential analysis
especially for hospitals
Benefits:
Identifies the status quo
Delivers a benchmark
Proposes relevant measures
Creates a value analysis

Best Practice Example
Martin-Luther-Krankenhaus Wattenscheid300 beds
Selection of measures implemented :
Heating
Installation of a CHP plant with 50 kW electrical and 80 kW thermal power output Installation of six gas condensing boilers for heating and airing the building.
Power supply and lighting
Use of low-energy light bulbs
Use of presence detectors
Energy management and staff involvement
Drawing up energy reports Constant monitoring and optimisation of the heating system
Briefing with the staff
SavingsThe measures reduced CO2-emissions by 20% (400 t per year).Investment: 615.000 - Annual savings 840.000 kWh natural gas and 46.000 kWh electricity
Energy cost savings of at least 110.000 per year

Possible explanations:
Energy efficiency is not recognized as having relevance
The potential for possible savings is not recognized
The theme is not communicated at the decision-making level
No means to finance the measure
Why are cost-saving potentials not realised?

- Conclusion - Hospitals are complex facilities with a strict focus on health care
Hospitals are among the largest energy consumers
Optimal energy efficiency can save up to 40 % on energy costs
Modernization and optimization of facility engineering creates many positive effects forhospitals
Uniform measures are difficult to define for hospitals
The biggest savings are achieved with the large consumers
by modernizing heating and cooling technology, as well as air conditioning andventilation technology
Measures are very easily identified with energy potential analyses and ranked accordingto economic efficiency
There are plenty of good examples for energy efficiency in hospitals that can bepresented as examples of best practice.
The topic of energy efficiency is not communicated sufficiently to decision-makers inhospitals and is not regarded to be important.
My message: Energy efficiency for hospitals pays off!
