ENERGY EFFICIENT REFURBISHMENT OF LAVRIO INDUSTRIAL HISTORICAL BUILDING COMPLEX

Objective

Energy efficient refurbishment integrating innovative renewable energies technologies and RUE (Expected energy saving : 774.3 Mwh/y, estimated annual monetary value saved : 43000000 GRD/y, expected of CO2 emissions : 50%, estimated payback : 10 years)
- Reduce of energy consumption and CO2 emissions
- Protection of the environment
- Social and economic impact on the degraded area of Lavrio and creation of new labor market
- Gaining the necessary expertise for other similar projects.
The first part of the Manufacture, Assembly, Installation and Erection phases of the project which includes the construction of the innovative metallic roof with the incorporated Solar Air Heating System has been completed. Also, the exterior site work is completed. Finally, tendering procedure for the E-M part and the remaining construction works to complete the project is ready to begin.
The project concerns the energy efficient refurbishement of an industrial - historical building at Lavrio. For this purpose innovative RUE and RES technologies will be integrated. For the production of the required thermal energy for heating and cooling, a small scale cogeneration unit (CHP), using natural gas, will be installed and at the same time, it will produce the appropriate electrical energy for the needs of the building. The energy surplus will be used by the neighbouring buildings. The heating of the space will be obtained by the recirculation of the air through the ducts in the walls which will be insulated and the insulated roof where a solar air heating system will be constructed. Additionally to this method, the air will be also heated by the CHP unit. The cooling will be obtained by absorption chillers using recovered heat from the cogeneration unit. The lighting of the building will be obtained by combined natural and artificial lighting. For this purpose, innovative insulation materials will be placed at the reconstructing roof and windows in order to obtain natural lighting. In parallel, artificial lighting is also provided. Finally, for the control of all the above installations a Building Management System will be installed. It is noted that, the energy and thermal power surplus will be used by the other installations and buildings of the technological park.
Innovative aspects :
- the use of small scale combined heat and power (cogeneration unit)
- the heating system using the solar air heating system
- the absorption cooling using recovered heat from the cogeneration unit
- the transparent insulation o fthe roof and windows.
