Heating systems are a major contributor to carbon emissions in commercial settings. Typically powered by fossil fuels like natural gas, oil, or coal, these systems release a significant amount of carbon dioxide (CO2) and other greenhouse gases. For example, studies show that in the US around 32% of all energy use within commercial buildings can be attributed to heating systems.

What types of heating systems are there? 

In commercial buildings, a variety of heating systems are used, each with its own set of characteristics and efficiency levels. The most common types include:

• Forced air systems - These systems are commonly used in commercial settings. They work by heating air in a furnace and then distributing it throughout the building via ductwork and vents. These systems can be powered by natural gas, oil, or electricity.
  
• Radiant heating systems - Radiant systems deliver heat directly from a hot surface to the room. In commercial buildings, they are often found in the form of in-floor heating systems, where pipes under the floor circulate hot water or an electrical heating system.
  
• Hydronic (boiler) systems - These systems use a boiler to heat water, which is then circulated through a series of pipes to radiators or baseboard heaters. This method is efficient for heating large commercial spaces and can be fueled by natural gas, oil, or electricity.
  
• Heat pump systems - Gaining popularity for their energy efficiency, heat pumps work by transferring heat from the outside air or ground into the building. They are particularly effective in moderate climates and can be used for both heating and cooling.
  
• Geothermal systems - Although less common, geothermal heating utilizes the earth's stable ground temperature to heat and cool buildings. This system involves pipes buried in the ground that circulate a fluid, which absorbs heat from the ground in the winter and dispels heat in the summer.

The environmental impact of traditional heating systems 

The International Energy Agency (IEA) reports that the operations of buildings account for 30% of global energy consumption and contribute 26% of global energy-related emissions - 8% of which are direct emissions, and 18% attributed to indirect emissions resulting from the production of electricity and heat. 

💡 These figures are on the rise - in 2022 for example, energy use in the buildings sector increased by 1%.

This is why reducing the carbon footprint of heating systems is essential for achieving global climate goals. For businesses, adopting eco-friendly heating solutions can also lead to a number of benefits including reduced energy consumption and lower operational costs.
