Green Tech Inside

The rigorous continuation of Bosch’s sustainability concept – “Green Technology inside” – is founded on clear facts: According to the International Energy Agency (IEA), private households are the world’s second-largest consumer of energy, accounting for a share of almost 30 percent, and the third-largest source of CO2 emissions (21 percent). Some 37 percent of the energy consumed by private households in Europe is used by domestic appliances – from the toaster to the washing machine.

And in this respect, fridges and freezers occupy a special position: In operation around the clock, they on their own are responsible for 15 percent of the electricity costs incurred by households. Where the most energy is used is also where the most can be saved. In line with this principle, Bosch has not only invested in cutting-edge efficiency technologies for its dishwashers, ovens, washing machines or small domestic appliances in the past years, but has also kept on optimizing its fridges and freezers. The latest result of these efforts is the Smart Cool product line, which is given its international premiere in 2011. It is our first series to consist solely of appliances in the top energy efficiency classes A++ and A+++. This means: Their energy consumption is respectively 40 and 60 percent less than the threshold of what used to be the best class A.

       Is sustainability becoming more important for the public?

Yes, but it is only one aspect. It’s hardly possible to sell domestic appliances that are merely miracles of economy, but don’t perform as hoped, even against the backdrop of a more stringent climate protection policy. That’s why we’re always seeking solutions that combine the two: Maximum functionality and minimum consumption. Energy prices are now rising so consumers are really considering how much they are spending for appliances and how much they will save during its lifetime. We see this not only in refrigerator, but also when it comes to water usage in dishwashers and washing machines, and also energy consumption of small appliances, so it’s topical for all product areas. 

What’s special with your new fridge?

We optimised the whole cooling system so we can really achieve outstanding energy efficiency. There are a lot of components that play into this energy efficient cooling system including a special wraparound evaporator, which is covered by a case that keeps the energy efficiency high. This is supplemented low frost technology, which reduces the ice built-up. Also, insulation is a big factor that’s why we have further optimized it, as well as the electronic controls to monitor the energy use.

Can you tell us about your new energy efficient vacuum cleaner?

I'd like to focus on four important features. Feature one is the compressor technology which is based on an intelligent air duct and an innovative motor whose aerodynamic fan blades achieve top speeds of up to 800 km/h, thereby ensuring maximum power on the carpet, but with low energy consumption. Second: The efficient air flow and reduced air resistance ensure extra-powerful dust pick-up with extremely low power consumption. Third feature is the intelligent SensorBaglessTM self-cleaning system. This is a fully automatic filter cleaning system which helps to ensure maximum air flow. And fourth: At only 75 dB(A), the Roxx’x ProEnergy is one of the quietest bagless vacuum cleaners in Europe.

What is the future of energy efficiency appliances?

For us, it’s continuous. Our product developers are continually trying to improve products and while at this point, I cannot clearly say how, our product development map will continue to increase the energy efficiency of our future products.
