MED-ENEC - Energy Efficiency in the Construction Sector in the Mediterranean


External cooperation programmes - European Commission

Pilot Project Lebanon

Renovation of the Centre Hospitalier du Nord, a one block hospital building built in 1986, with 110 capacity, 6000 m2 floor space, located in Zgharta - North Lebanon.

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.


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.


Main technical features of the Pilot Project

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.

Main results of the Pilot Project

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.
