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, with almost a century of experience in heat exchanger HVAC technology, 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.

HVAC and sustainable cities

The key to sustainable cities

  • Effective and widespread use of renewable energy sources in urban applications
  • Thermo storage tech for efficient storage and management of excess heat or cold, reducing energy waste and supporting sustainable urban development
  • Geo thermoelectric systems harness thermal energy from the Earth's subsurface to provide renewable heating and cooling solutions
  • Heat reuse initiatives, like district heating and industrial WHR, are essential for maximizing energy efficiency and minimizing emissions

Energy efficiency to power net zero

Even though cities occupy only 3 percent of the Earth's land, they contribute to a staggering two-thirds of global energy consumption and 70 percent of CO2 emissions. Cultivating energy-efficient cities is crucial for decarbonizing the future and creating a sustainable world.

With almost a century of experience in heat transfer efficiency and recovery, Alfa Laval has heat exchanger HVAC solutions at the 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.

These innovative solutions pave the way for a future where HVAC applications play a pivotal role in creating energy-efficient cities and a greener planet. 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!
