Cogeneration is combined generation of heat and electricity. The advantage of cogeneration is that it enables the heat released by electricity generation to be used. The most well-known form of cogeneration is an electricity generator powered by an internal combustion engine, with the heat released by the engine being used to produce steam and/or hot …
Energy Efficency In Hospitals – Lighting (part 5)
Lighting is one of the large energy consumers in hospitals, just as in many other kinds of utility buildings. Various studies have shown that some 20% of the total energy consumption in a hospital is accounted for by the lighting installation. When it comes to the energy savings that can be made on lighting, these …
Energy Efficency In Hospitals – Steam (part 4)
Steam is used a great deal in hospitals: it permits high energy densities and enables large amounts of energy to be moved around easily. Steam can easily be generated from water, which is present everywhere in large quantities. Furthermore, steam installations are relatively easy to regulate. Steam is used for many applications in hospitals, including …
Energy Efficency In Hospitals – Compressed air
Compressed air is an essential form of energy for a hospital. Depending on the requirements it can be divided into: – Medical compressed air and – Technical compressed air Medical compressed air Medical compressed air has many uses in a hospital. Examples include assisted respiration for patients and driving surgical tools. Very strict requirements are …
Energy Efficency In Hospitals – HVAC (part 2)
In the following chapters we look at a number of case studies for energy saving options. These are subdivided into the following areas: – HVAC – Compressed air – Steam – Lighting – Cogeneration For each of these areas we first give a general explanation, followed by some practical examples taken from various studies carried …
Energy Efficency In Hospitals (part 1)
The great majority of the energy used within a hospital is purchased from outside in the form of natural gas and electricity. A small proportion is bought in as diesel oil. The energy bought in is converted by a number of conversion systems into the most important internal flows of energy, namely heat, cold, electricity …
