In the heart of Tehran, researchers are digging into the dirt—and they’re finding gold. Not literal gold, but something that could be just as valuable for the energy sector: a sustainable, cost-effective way to heat and cool buildings. Younes Noorollahi, a researcher at the University of Tehran’s Energy Modelling and Sustainable Energy System (METSAP) Research Lab, has been crunching the numbers on ground source heat pump (GSHP) systems, and his findings could reshape the way we think about building energy systems, especially in regions like Iran.
Noorollahi’s study, published in the journal ‘Energy Conversion and Management: X’ (translated to English as ‘Energy Conversion and Management: Next Generation’), compares the techno-economic viability of GSHP systems against conventional HVAC systems across Iran’s diverse climatic regions. The results are promising, to say the least. “We found that purchasing surplus energy at a reasonable price can yield an attractive return on investment when GSHP systems replace conventional HVAC systems,” Noorollahi explains. This means that not only can GSHP systems help offset the additional capital costs, but they can also improve system efficiency and, in some cases, even generate profits.
The implications for the energy sector are significant. As energy policymakers grapple with the need to promote more sustainable systems, Noorollahi’s research provides a practical framework for transitioning from outdated, fossil-fueled heating and cooling systems to more environmentally friendly alternatives. The study highlights that in the best-case scenario, energy savings of 230.4 MWh and CO2 emission reductions of 131.5 tons can be achieved over the system’s 30-year lifetime.
But what does this mean for businesses and investors? For one, it means that there’s a potential goldmine in the form of energy savings and reduced emissions. It also means that there’s an opportunity to tap into a growing market for sustainable building solutions. As Noorollahi puts it, “This approach enhances economic viability and stakeholder acceptance, making it a win-win for both the environment and the bottom line.”
The study also offers a practical procedure for assessing the techno-economic feasibility of replacing conventional HVAC systems with GSHP systems. This could be a game-changer for researchers and policymakers looking to make a dent in the building sector’s carbon footprint.
As we look to the future, Noorollahi’s research could shape the way we think about building energy systems. It could pave the way for more sustainable, cost-effective solutions that not only benefit the environment but also make good business sense. And in a world grappling with the challenges of climate change, that’s a win worth digging into.
