Energy efficiency in the HVAC sector can help reduce the effects of heatwaves

While governments around the world are having to deal with the results of recent extreme weather, the Heating, Ventilation and Air Conditioning Sector has an important role to play in achieving greater environmental awareness, sustainability and efficiency. It is essential that we use all possible means to reduce CO2 emissions. Industrial heating is responsible for around 20% of industrial energy consumption. Buildings and construction between them create nearly 40% of CO2 emissions. There are several areas where the HVAC sector can improve its energy efficiency.

Higher temperatures everywhere make air conditioning more necessary than ever, but you can overdo anything. Unnecessary ventilation wastes energy and causes excess emissions. Recirculating air used to be the solution, but Covid-19 has taught us the dangers of this; we can also recirculate disease-causing organisms. Airconditioning is responsible for around 10% of the UK's electricity consumption, so we need to find ways to reduce the resulting increase in emissions. A study of how different countries deal with this would be helpful.

Smart Technology provides one way to improve energy efficiency. As the incidence of heatwaves increases, sensors linked to air conditioning can help control usage, and reduce excess. Wireless technology can be operated with handheld devices, reducing the need for travel. Smart thermostats, smart furnaces and new, easy-to-operate airconditioning systems will all be needed, as global warming accelerates.

Another useful advance is the use of modular HVAC systems. These give a more energy-efficient, cost-effective and flexible means of heating, cooling and distributing air through your workplace building. Modular systems are easy to install and maintain, and can be adapted to the specific needs of any workplace, avoiding waste and excessive carbon emissions. Being easy to maintain, without disruption to those working in the building, modular systems are ideal to help meet both government and industry regulations. This is particularly the case with new buildings.

Companies such as Germany's Wilo Group are already aiming for carbon neutrality as soon as possible. This company has a plan for sustainable manufacturing, including the construction of a new carbon neutral manufacturing plant and headquarters. Many other companies are considering altering their plans for development to include similar initiatives, and are also placing emphasis on the importance of training all workers, especially installers and maintenance, in the most energy efficient ways to work, while creating significantly less carbon emissions.

All these are good ideas; smart technology which can be operated remotely will make a big difference. But, given the role of HVAC systems in adding to emissions as temperatures rise, we need to find every possible way to make the industry even more energy efficient.
