Clean and lean water use

• Installation of drip-feed irrigation system reduces water consumption by 5 100 m3 and saves ~€ 7 000 per year
• Reorganising tank cleaning saves € 800 and cuts yearly water consumption by 1 200 m3

A winery located in Southeast Europe significantly decreased its water consumption through a clever rethinking of its irrigation and cleaning processes.

Comfort... hard to quantify but worth investing in

• Heat recovery saves money, improves working comfort in winter
• Resulted in annual savings of 218 MWh of heat (equivalent to over € 17 000) 

A company producing cables for electricity infrastructure located in the Czech Republic carried out a comprehensive energy audit resulting in several energy-saving measures. One of the proposals was to reuse waste heat from two production areas to warm adjacent halls.

Excellent recovery!

• Recovering heat saves on energy and cuts CO2
• Results in annual energy efficiency gains (~3.5 %) and less CO2 emissions (~600 000 kg)

Carlsberg brewery is an energy-savings front-runner in line with its mission to optimise production and reduce overall CO2 emissions and energy consumption costs. 

Push-button timers fit for shower time  

A push-button timer is a relatively simple technology for restricting the water flow of a shower to a designated length of time. Water stops running when the timer runs out, which prevents wastage. This reduces water utility bills and saves the environment.

How do they work? Push-button timers are a mechanical device (a pinhole within a diaphragm) that effectively closes the valve in the tap after around 30 seconds.

Cistern displacement or dual flush? Your choice

Cistern displacement and dual flush are increasingly popular water-saving techniques. Authorities in many water-stressed places, for instance, are pushing this low-flush approach to safeguard a precious resource.

Dual-flush mechanisms are usually incorporated in new low-flush toilets, but may also be retrofitted to existing cisterns. These mechanisms have two buttons; one launches a full flush (e.g. 6 L) for solid materials; the other a half-flush (e.g. 3 L) for urine or liquids.

Low-flush toilets let gravity do its job…

Low-flush gravity toilets with optimised cistern and bowl designs use 4-6 litres of water per full flush. This system can help you save up to 6 litres of water per full flush compared to conventional systems.

Low-flush toilets are universal and can be easily fitted. Read ‘Cistern displacement or dual flush’ for other alternatives!

Try aerators to better regulate your shower and tap flow!

Aerators (flow regulator) are simple vacuum valves with an air intake that can be easily installed between the tap and hose, or between the hose and shower head.

Retrofitted to taps, the aerator – with or without flow regulators – can reduce the flow rate whilst generating less splashing to achieve better perceived ‘wet effect’ and efficiency.

Go with the (low) flow water fixture!

Low-flow water fixtures are a range of easily implementable technologies that help you save water and money by allowing the user to control how much water is consumed.

They use a high-pressure technique to produce a strong and consistent flow that actually uses less water than inefficient traditional fixtures. These clever fittings can be applied to sinks, showers, and toilets.

Implementing a virtual desktop infrastructure (VDI) hosts a desktop operating system through a centralised server. This means no need for individual PCs, as employees access the system and their files via a standard keyboard and monitor. With VDI companies can implement a multi-user IT system at the fraction of the cost of conventional desktop stations.
