Making the world’s buildings more energy efficient

Buildings are responsible for about 40 % of the worlds energy consumption, and heating and cooling is responsible for about 60 % of this energy use. However, by adopting more energy-efficient heating and cooling systems, as well as clean energy technologies, we can reduce energy consumption and carbon emissions in the building sector by 50%. We can also move away from gas as a source of energy altogether. At Alfa Laval, we offer the solutions needed to support this transition.

Trend in Industry

Energy poverty is a growing problem worldwide, particularly in Europe, where around 36 million people could not keep their homes adequately warm during the winter of 2020. But did you know that only seven countries across the EU and UK account for 80% of Europe’s entire residential gas use? To reduce dependence on gas and improve energy efficiency, we need to implement a range of solutions, such as:

  • Renovating old houses and public buildings with new, more energy-efficient heating and cooling solutions.
  • Strengthening existing building codes to meet energy efficiency standards.
  • Connecting buildings to updated heat network systems or district heating, providing alternative energy options.
  • Implementing digital solutions to monitor and optimize energy use in buildings, including larger system solutions utilizing buildings as thermal storage during peak hours.
  • Installing heat pumps in houses and reusing heat in commercial buildings.
  • Introducing cooling strategies in high-demand regions to tackle exponential air conditioning growth.

Alfa Laval’s heating and cooling solutions

Achieving net zero requires equipping houses and buildings with efficient heating and cooling solutions. This means finding the right solutions for new builds and updating existing structures. One crucial example of this is connecting to district heating and heat networks. At Alfa Laval, we offer a range of solutions that enable using renewable energy and reusing of excess heat from substation applications to heat entire districts. We even have components that support smaller-scale heat reuse at the end-user site. Our products work seamlessly with natural refrigerants, reducing your environmental impact regardless of which solution best fits your specific process.


Pressure breaker

Taller buildings like skyscrapers and structures requiring large energy systems face a challenge where the static head creates pressure that can exceed the capacity of the chiller condenser or air conditioner. With an Alfa Laval plate heat exchanger, you can split the circuit on any floor to maintain the correct levels and reduce the strain on your pumps, piping, and valves. The best part of this solution is that it can be used as a pressure breaker, adding as many as your building height requires. But that's not all; our "close approach" technology allows for the transfer of practically all the cold to the top of the building with minimal loss.
