Would you like to save energy and do something good for the planet?

Create symmetry and harmony in a sustainable bathroom

In nature, symmetry is all around and is beautiful. Humans crave symmetry and order, and as a result, normally position and start the water flow of the bathroom faucet with the lever positioned in the middle.

As satisfying as this is from an aesthetic point of view, for ordinary faucets this is the “mixed” position that draws unnecessary warm water to the basin mixer, even though we often only need cold water.  Just think about when you use the faucet first thing in the morning to clean your teeth. 

This may seem like a small affect, but over time it makes a big difference in the cost of energy for the bill-payer and for the environment.

The intelligent combination of energy saving and effortless water control

The solution

GROHE Energy Saving (ES) faucets have a middle position where only cold water is demanded. The lever can only move left from its middle cold position – so the user will not draw unnecessary warm water.

In cold-water mode and positioned mid-lever, the Energy Saving technology springs into life. This eliminates opening the faucet in the mixed hot-and-cold water mode, saving energy by avoiding the unnecessary heating of water for daily rituals like cleaning your teeth or washing your hands.

GROHE Energy Saving technology not only offers a unique smoothness of operation, but also encourages responsible management of energy and water.

So how much can you save?

From standard usage patterns verified with the BDEW*, our calculation shows significant saving potentials over time. In this example, a property owner managing 1000 apartments saves 27.779 EUR per year if shifting from a normal single lever mixer to an energy saving mixer from GROHE – even though the water flow is the same. If the property manager has old mixers with a higher flow, the saving would be even larger.

Leon Dijkstra

CEO Eden Hotels

As a third-generation Dutch family-owned business, we have been looking after guests and colleagues for almost 75 years. This is only possible when you have the future and best interest of all stakeholders constantly in mind. With our hotels we want to significantly lower our footprint. In other words: our goal is to become a carbon neutral company. To realise this, we have gathered all the necessary information on what is technically feasible, which we will implement where possible and sensible. We concentrate on water, energy and of course, reducing waste as much as possible. When renovating the Savoy Hotel Rotterdam, we wanted to reflect Rotterdam’s energy and renewal and therefore chose to refurbish with as many sustainable options as possible. We know that guests often use more water whilst staying in a hotel compared with a home, but we did not want to compromise on their enjoyment during their stay. We therefore chose to install GROHE ES energy and water saving option to help us continue on our sustainability journey and deliver at the same time the best guest experience. Our objective is to make our hotels “A Home for you. For us. For always”.
