Consuming more than two-thirds of the world’s energy, our cities play a crucial role in tackling the climate crisis. A considerable part of cities’ energy consumption is for heating and cooling, which means improving energy efficiency is paramount. Alfa Laval has almost a century of experience in heat transfer and recovery and aims to become carbon neutral by 2030. Let us be your partner in the transformation to a sustainable tomorrow. Together, we can decarbonize the world.

The key to sustainable cities

  • Flexible, robust, and efficient energy systems make it possible to switch between different energy sources without any adjustments.
  • Fossil-free energy sources that allow us to reduce the CO2 footprint.
  • Heat-efficient buildings with reduced carbon footprint that save energy while catering for the needs of their occupants.
  • AHRI third-party certification program offers confident assurance of the heat exchangers' design and performance in all parts of the energy system.

Energy efficiency to power net zero climate goals

Even though cities today occupy only 3 percent of the Earth’s land, they account for two-thirds of global energy consumption and 70 percent of CO2 emissions. That is why cultivating energy-efficient cities is crucial for decarbonizing the future and creating a sustainable world.

Heating and cooling are some of a city’s largest energy expenses, yet basic needs for all individuals. Since most of the energy used for heating and cooling today is produced from fossil fuels, this sector requires urgent action.

With almost a century of experience in heat transfer efficiency and recovery, Alfa Laval has the solutions ready. Our compact energy-saving plate heat exchangers can tap into various energy sources, including renewables and recyclables, to provide cost-, energy-efficient, and comfortable heating and cooling. We aim to be carbon neutral by 2030. Let us be your partner in energy efficiency and clean energy transition.

See the numbers: HVAC energy efficiency potential

Heating and cooling are some of a city’s largest energy expenses, yet basic needs for all individuals. Since most of the energy used for heating and cooling today is produced from fossil fuels, this sector requires urgent action.

Fortunately, the design of HVAC systems offers an enormous untapped potential for improving the climate impact of our buildings. Whether it’s about more efficient solutions that reduce energy and water consumption, or the phasing out of refrigerants with high global warming potential (GWP), there is much we can do already today. A heat pump, for example, is four times more efficient than a boiler for heating residential and commercial buildings, enabling incredible potential to shrink energy consumption and carbon emissions.

Imagine if we replaced all of today’s residential and commercial HVAC boilers with efficient heat pumps. The annual energy savings would be 230 TWh. That’s the same amount of electricity as that consumed every year in all of Spain!
