The aim of the pilot project is the  implementation of energy efficiency measures based on the results of an energy  audit of the existing building. As 75% of the electrical energy used in the  hospital is produced by expensive diesel generators, the main focus of the  adopted strategy is twofold: optimizing the cost per kWh and reducing energy  waste.

Profitability
  With the MED-ENEC pilot project, annual  energy cost savings of almost 40,000 € could be realized. As only relatively  low investments were required, the pay back period remained very short with  only 1-2 years. The measures can therefore be implemented in any other  comparable building without subsidies or substantial investments.
 

The energy concept is based on the result  of an energy audit, in which different energy efficiency measures were  investigated. For a solid basis of the energy audit data on energy consumption  and costs were collected and measured, which can be classified in two groups:

  1.   Statistics  and data collection: Electricity bills, Diesel oil bills, equipment and appliances count, equipment and appliances  nominal power, qualitative notes...
  2.   Physical  Measurements: Lighting feeders (ampacity, KW and power factor), AC  feeders, load profile for chillers,  generators load profile, etc.

Further to energy audit, the following  basic measures with high / moderate cost efficiency were implemented:

 
• Air conditioning  efficiency improvement through maintenance
 
• Energy efficient  lighting
 
• Peak shaving  through demand side management
 
• Improvement of  boiler and generator efficiency
 
• Thermal  insulation of the roof

The installation of a solar thermal  equipment was considered but not realized, as the existing water heating system  was still rather new and as excess steam from oversized steam boilers is  available to heat water.

The project is an energy related retrofit  measure where all energy efficiency measures were determined in an earlier  energy audit.

As 75% of the hospital''s energy is produced  by expensive diesel generators during frequent power cuts, a demand side  management system and technologies reducing energy waste were implemented.

Focusing on extremely cost effective  measures, almost 20% of the energy costs of around 270.000 €/year could be  saved with relatively low investments. With a pay back period of only 1-2  years, the measures can be replicated without any subsidy in any other  comparable building. (link to the chart)

CHN has already decided to use the positive  experiences of the pilot project for a new hospital building that is being  constructed in Jounieh, a costal city north of Beirut.
