We all have a responsibility to make a net zero carbon future a reality – and here at Xylem, we are committed to helping our partners solve the toughest water and resource challenges.
With nearly one in three buildings older than 50 years and almost three-quarters of building stock considered energy-inefficient, renovating existing buildings has the potential to lower total carbon emissions by about 5%. Taking steps towards sustainability can not only save energy and operating costs for buildings today but guarantee their durability for the future.
Xylem’s state-of-the-art energy-efficient solutions offer consultants, architects, facilities managers and engineers the opportunity to harness the power of energy-saving technology and rapidly recoup costs by significantly reducing usage.
Start with an energy audit
Operational emissions from the energy used to heat, cool and light buildings account for almost a third of the world’s carbon emissions, making building systems an easy target for savings. And lowering the impact of our buildings should extend to reducing water usage in the face of growing water scarcity.
A professional building systems audit from Xylem can uncover dated technology, leaking equipment, poor design or shoddy installation which may hinder performance and potential optimisation. Oversized heating systems can use 50% more energy than necessary, for example, an inefficiency which our experienced engineers can identify and then offer a more sustainable alternative.
Plug-and-play solutions for HVAC
Retrofitting sustainable solutions such as high-efficiency circulators and pumps for heating, cooling and hot water applications can bring immediate benefits.
Changing environmental conditions can be better managed, while thermal energy meters can provide continuous information on the network to allow for adjustments in real time and curb energy use.
Save energy and water
Sub-metering by Cordonel and iPERL is a valuable step to save water by collating data on consumer demand. And, by supplying water only when needed, system control measures can help to reduce energy use by up to 70%. Fully automatic booster sets like the Lowara GHV series can guarantee a stable water pressure during unexpected peaks of demand, while ensuring the lowest energy consumption.
Similarly for wastewater, the Flygt Concertor’s smart pump technology - using intelligent drives, controllers and built-in application intelligence – helps it adapt according to demand to reduce energy usage by up to 70%. This can apply to new wastewater systems or replace existing inefficient systems.
Get smart about water reuse
More drastic solutions to cut back on clean water consumption may be considered in the longer term. Xylem worked with a water utility in Berlin, Berliner Wasserbetriebe, and the Berlin Centre of Competence for Water to produce a beer made from purified and treated wastewater, which could have important implications for the future of drinking water.
The water was treated with Xylem's Oxelia process before undergoing the Advanced Oxidation Process using our MiPRO process to guarantee the highest possible purity level. Read more here.
Building resilience from the ground up
Water is vital to the sustainability of our communities – and reliable building systems can play a pivotal role in making our built environment more resilient in the face of unprecedented challenges.
Buildings no longer need to account for almost a third of the world’s energy use, or a fifth of its water usage: upgrading building systems to run at peak efficiency with Xylem’s help can mean huge energy cost savings in the long term and help build a more resilient world.
