The Green Heat: Sustainable Heating Options for Commercial Buildings
By Erin Lorde
It’s no secret that the effects of climate change are becoming more prominent than ever, and more businesses are beginning to practice sustainable measures to make up for the emission statistics. A major area where greenhouse gas emissions can be reduced by businesses is in the heating systems of commercial buildings.
Traditional heating methods (which are often reliant on fossil fuels) are a huge contributor to carbon emissions and environmental degradation. But this doesn’t mean there are no solutions available – there’s a wide range of sustainable heating options that not only help businesses lower their carbon footprint but also save on energy costs. This article explores some of the most promising sustainable heating solutions for commercial buildings.
Geothermal heating is one of the top ways to draw heat without skyrocketing emissions. It uses 25% to 50% less electricity than conventional systems. This method taps into the Earth’s natural heat source and pulls heat consistently. It uses geothermal heat pumps to allow the heat to travel up to commercial buildings and can be reversed depending on the seasons.
This technology uses geothermal heat pumps to transfer heat from the ground to the building’s inside during colder months and reverses the process during warmer months to bring down the temperature.
Some of the advantages include:
- High energy efficiency
- Minimal maintenance requirements
- A long lifespan
- Ability to reverse for hotter/cooler months
If you’re looking for something budget-flexible, solar heating may be the best way forward for your business. Taking advantage of the sun’s heat has become immensely popular over the past decades and the technology has become widely used in both commercial and residential properties.
Solar thermal technology is used to convert sunlight into heat, which is then used for space or water heating purposes and can also be used alongside panels that convert the light into electricity.
The benefits of implementing this method can be:
- Reduces energy bills significantly
- Makes you energy independent (reduces reliance on external sources)
- Requires minimal upkeep efforts
- Built to withstand various conditions
Note: Certain regions offer incentives and tax benefits to businesses adopting solar heating systems.
This method of heating usually operates by using organic materials like wood pellets or agricultural leftovers and burning them in boilers or furnaces. This then generates heat for water, steam, or even warm air which can all be used in commercial buildings.
When these leftovers (biomasses) are burned, it releases CO2 into the atmosphere, but the carbon emitted during the combustion is all part of the natural carbon cycle. Plants use CO2 through photosynthesis when they grow, so when they’re burned this co2 is released meaning no more is produced, and something is created called a ‘closed carbon loop’. This means that there is no more contribution to the co2 levels, and you can recycle the carbon from the plants instead.
Biomass heating should be considered as a heating option, as:
- It creates a closed carbon loop
- Generates an efficient waste management solution
- Can be implemented flexibly within a budget
- Reduces dependence on fossil fuels
Heat pumps, much like geothermal heating, can extract heat from the ground – but these can also pull from the air and water too. There are three main types of heat pumps: air-source, ground-source (geothermal), and water-source.
These can deliver multiple times more heating than commercial buildings can use – but finding the one that fits best will depend on what outcome is desired.
Air-source heat pumps are the most common and cost-effective, while geothermal heat pumps offer higher efficiencies in extreme temperature climates.
Heat pumps offer numerous advantages, like:
- Long lifespan and durability
- Low maintenance requirements
- Reduces reliance on fossil fuels
- Provides both heating and cooling solutions
District heating systems use an interlocked system of insulated pipes which supply heat from a main source to multiple buildings. By reusing waste heat from industrial processes, this method provides effectual heat generation and distribution.
This way of heating can drastically reduce energy consumption and greenhouse gas emissions compared to individual building heating systems. It provides flexibility in integrating various renewable and low-carbon heat sources, making it an attractive sustainable heating option for commercial areas.
Some of the additional bonuses include:
- Recycling of waste heat
- Integration of renewable energy
- Flexibility in heat sources
- Potential for combined heat and power (CHP)
The adoption of sustainable heating options in commercial buildings is of utmost importance in order to reduce carbon emissions and combat climate change. Geothermal heating, solar heating, biomass heating, heat pumps, and district heating systems present sustainable alternatives to conventional fossil fuel-based methods. Each solution offers unique advantages and considerations, including initial costs, local resources, and climate suitability.
By including these heating alternatives, businesses have the power to contribute to a greener future while reaping long-term energy savings and reducing their environmental impact. Investing in ecological heating isn’t only a responsible choice but also a strategic step towards establishing a more sustainable and resilient business operation that aligns with our planet’s welfare.
