The Ministry of Economy and Finance of the Junta de Castilla y Leon has installed efficient LED lighting technology in sports facilities for the first time. The action has been developed through the Regional Authority for Energy (EREN), an organization that develops, unifies and integrates policies concerning various energy areas at the regional level. The aim of this action is to widespread the use of LED lighting technology in unique buildings.
The improvement has been executed in the covered pavilion Rio Esgueva of Valladolid, which has a main camp and three transversal one. These spaces are used on the base of intensive schedule, especially during the school year. A demonstration test of efficient technology both in sports courts and Assets of Cultural Interest was also carried out in this facility. The aim of this study is to promote the implementation of efficient lighting techniques in unique buildings. With the results of the project a guide a will be developed that will collect a series of recommendations to make their use feasible from a technical and economic standpoint.
In the first phase of the study, two photometric measurements in different weather conditions were performed with the original fittings, consisting of 30 bells with metal halide lamps and a total installed capacity of 12.6 kilowatts (kW). Then the new lighting model was installed leaving the original in place as well. This was done in order to make a comparative analysis of the performance of both more accurately. Therefore, they placed 30 dimmable LED luminaires totaling 6 kW of installed capacity which are modulated automatically by photometric sensors for the exercise of each sports activity depending on the amount of natural light.
Seven years payback
In measuring the LED system, substantial improvements were verified. This technology is more efficient, provides optimal performance and requires less power, which significantly reduces energy consumption and thus the cost of the electricity bill. Specifically, with an output of 6 kW, the annual power consumption is reduced by 85%. This reduction depends largely on the automatic lighting control system. The gross savings in the cost of lighting amounts to 3,761 euros a year. The investment estimated to install a lighting system similar to that implanted by EREN in sports facilities amounts to 26,900 euro. This amount would be paid back over a period of seven years in accordance with proven savings.
Due to the high consumption for lighting, the trend in Europe is to replace the lighting with new lighting technologies that are friendlier to the environment and with lower energy consumption. The Energy Strategy of the local government promotes a more rational use of energy from the active example. In recent years, this region has implemented efficient technologies in their own facilities, demonstrating the feasibility of these initiatives and reducing the energy costs associated.
