Commercial buildings use large amounts of electricity and natural gas. Significant reductions in energy use can be achieved by installing new modern systems but this requires a significant capital cost, It is possible to install modern control systems at much lower cost and these can also significantly reduce energy use, and improve comfort at the same time! A new study by the Pacific Northwest National Laboratory shows that commercial buildings could cut their heating and cooling electricity use by an average of 57 percent with advanced energy-efficiency controls, according to a year-long trial of the controls at malls, grocery stores and other buildings across the country. The study demonstrated higher energy savings than what was predicted in earlier computer simulations by the same researchers.

Algunas personas les gusta pasar sus vacaciones en un spa de lujo con aire acondicionado, un buffet interminable y una piscina con cloro que no alcanzan a pisar pero se encuentra a su alrededor.

Al acampar, es importante tomar medidas sostenibles y limitar su impacto. Tenemos que respetar la naturaleza si queremos que las generaciones futuras puedan disfrutar de ella.

There are electric satellites from Boeing and electric planes from Airbus, so why not electric roads, brought to you by Volvo Group?
Volvo, in collaboration with the Swedish Transport Administration, is studying the potential for building electric roads where city buses—built by Volvo, of course—can be charged from electricity in the road while the bus is in operation.
