Two successful tenders were held for the supply and installation of efficient indoor lighting fixtures and LED lamps for two of University of Patras' buildings
The existent lighting bulbs used in the Cultural Center and the Polytechnic Amphitheater of University of Patras were energy-intensive, demanded a high maintenance and replacement cost and offered a relatively short lifetime. As a result, it was deemed necessary to adopt a practice that would provide beneficial results for the sustainability of the environment, targeted at increasing energy efficiency, reducing energy consumptions, decreasing the outgoing emissions and protecting the environment.

By replacing the conventional lighting bulbs with cost-effective and economical special fixtures and lamps that use LED technology, we can achieve the aforementioned goals. LED lamps have 10 times longer lifetime that conventional lamps and offer increased durability. In addition, there are no heat emissions when they operate, their manufacturing is mercury-free and they consume far less electrical power, thus contributing to the sustainable protection of the environment.

Two tenders were procured (one for the Cultural Center and one for the Polytechnic Amphitheater). The contracts were awarded on the basis of the lowest compliant offer. The contractors were required to fully restore any damages caused during the supply phase to the facilities at no extra cost. They were also obliged to remove waste materials without any additional compensation and to deliver clean and ready to use building facilities. Furthermore, a five (5) year at least guarantee was set.

Resources needed

For the Cultural Center, the total cost of replacing and installing 515 lighting fixtures, 1900 LED lamps and 15 headlamps ended up at 48.565 €.
For the Polytechnic Amphitheater, the cost for a total of 700 LED lamps and 205 special lighting lamps ended up at 14.844 €.

Evidence of success

Both tenders were successful and the contracts with the suppliers were signed in November 2016. The implemented lighting fixtures and LED lamps have been efficiently operating ever since. The success of the inclusion of GPP criteria for tenders as stated above resulted in the University's decision to hold a new tender to upgrade the outdoor street lighting and ambient lighting network at the University' premises with LED lamps and luminaires. This contract is currently in the installation stage.

Difficulties encountered

During their implementation, both tenders did not encounter any major difficulties and as a result, the tendering process was considered to be highly successful.

Potential for learning or transfer

The proposed GPP practice is easily transferable to other organisations and has a big potential for transfer and learning. Needs addressed are common among sectors, organisations and different regions/countries. The organizational resistance risk is predicted to be extremely low, due to the vast majority of benefits offered by this best practice and the very common need of indoor lighting in universities.
