Good Practice Case Study: Efficient lighting in Latvian Academy of Sport Education, Latvia

Case Study (112 Kb PDF)

Summary

The renovation of an indoor lighting system in the Latvian Academy of Sport Education in Riga, Latvia has sensibly improved the quality of light and led to significant reductions in energy usage. Efficient lighting technology has been installed in a sport hall of the Academy, making it safer and more comfortable for students to go about their training. The project can already point to energy savings amounting to 83 500 kWh per year, along with a reduction in CO₂ emissions of 30.4 tonnes per year. The project was implemented by an Energy Service Company and the Academy administration is now on the way to announce a new tender for the renovation of the heating and water supply system.

Results

The project has achieved its main objective, which was to reduce energy consumption and stop the physical degradation of the lighting system in the sport hall. By using better technology, the network’s energy use has been cut by 83720 kWh per year. Although the small project size, the figures are also good in terms of CO2 emissions, which have been reduced by 30.4 tonnes per year.

The system now has a much better control system – including the possibility to have different light levels in the hall in function of different applications and sports played.

The project has achieved as well as the objective of using third party financing, although it has been very hard to involve an ESCO in this small scale project.

In table 1 below is shown a comparison before and after project implementation.

In the economical lifetime of the project of 10 years, the project will achieve a total CO2 emissions reduction of 304 t.
