This is the good practice's implementation level. It can be national, regional or local.
About this good practice
The Nature Park project consists in the planting of over 15,500 trees + the restoration of a historical building. Specific objectives of the project are:
-restoration of the building;
-protection of an area of high ecological value;
-demonstration of the benefit of renewable energy sources;
-treatment of waste water;
-creation of green open spaces for the general public;
-creation of scientific and educational facilities.
RES installed:
1) Photovoltaic electricity generation: designed to have three different PV technologies: mono-crystalline, poly-crystalline and thin-film.
2) Micro-wind turbines: two types of wind turbines, (vertical axis and horizontal axis), were installed.
The PV and wind system of inverters was designed to allow electrical energy generation in grid connection mode and in “controlled” stand-alone mode. In the case of electrical grid failure, this system makes it possible to power the building to a limited extent as long as the PV and wind devices are still generating electricity. Once installed, the stand-alone inverter shall be programmed with a load shedding program so as to provide electricity only to the building’s high priority loads.
Finally, both PV and micro-wind technologies are connected to a data-logging system, which can be used to monitor various environmental parameters. The data shall be displayed in the building’s lobby in real time.
The solar water heating has been intended to provide hot water supply to toilets and showers.

Evidence of success
PV system installed: annual savings in kWh:23500; annual reduction of CO2 in Tonnes: 20,5.
Wind System installed: annual savings in kWh:16000; annual reduction of CO2 in Tonnes: 14.
SWH system installed: annual savings in kWh:20075; annual reduction of CO2 in Tonnes: 17,5.
During 2006, it was reported that 0.8782 kg of CO2 were emitted for every kWh generated (Enemalta).

Potential for learning or transfer
The project results have shown many benefits and potentials for future projects:
-better economy for stakeholders;
-practical use of Renewable Energy Sources and use of treated wastewater;
-development of ecotourism in the area;
-showcase of the Nature Park and Sustainable Development Centre;
-environmental education facilities;
-possible future funding for other conservation projects.
