Positive effects on the environment - Economic benefits
Efficient Lighting A variety of technical solutions
Efficient Lighting Advantages • 70% less electricity consumed • Better quality of lighting • Reduced need of cooling • Longer useful life of fluorescent tubes • Weaker magnetic fields • Better personal safety
Efficient Lighting Results • 70% less electricity consumed • Reduktion of the electric consumption with 5 GWh/år • 14.000 light fittings replaced by 10.000 new
50% Less electric and energy for heating is consumed for ventilation in hospitals an other building EFFICIENT VENTILATION
Efficient Ventilation Advantages • 50% less electricity and energy for heating • Air flow can be effectively regulated • Central monitoring • Improved heatexchangers
Efficient Ventilation Results • 50% less electricity and energy for heating • Reduktion of the energy consumption with 6,5 GWh/år
Results of Snowcooling 2000-2008 • Reductionof electricity use is more than 90 % • Chillers have been replaced for: - climate cooling • - cooling of X-rays and radiation • - cooling of servers • The cold in polluted snow is used • No disturbance during the 9 years of operation • 20
Environmental benefits of Snowcooling 2000-2008 • 90% reduction of CO2 from production of the eletricity • Most of the refrigerants are phased out • Purification of melt water from polluted street snow 21
Results 10 years work with real estates • 30% less electricity consumed • 35% less energy needed for heating • All fossil fuel replaced by renewable energy • 50% lower CO2 emissions • 75% of compressor refrigeration, replaced by free cooling from snow, rivers, groundwater etc. • 4 million euros reduction - annual energy costs
