What are the benefits of using geothermal systems according to LEED?

Using geothermal systems offers several benefits, particularly in terms of maintaining consistent indoor temperatures. This stability in temperature is a result of the geothermal system’s ability to draw on the relatively constant temperature of the earth beneath the surface. Unlike traditional heating and cooling systems that can be affected by outdoor weather fluctuations, geothermal systems deliver a steady level of comfort indoors. This not only enhances occupant comfort but also contributes to energy efficiency, as the systems operate more efficiently and effectively than many conventional systems. Such efficiency and comfort are aligned with the goals of LEED, which advocates for sustainable practices and improved environmental performance in buildings.

The other choices do not align with the principal benefits recognized within the context of LEED and geothermal systems. While insulation is still necessary for building performance, geothermal systems do not eliminate maintenance costs; they typically require periodic maintenance to ensure optimal performance. Additionally, geothermal systems are designed to reduce, not increase, energy consumption, making them a sustainable option in alignment with LEED principles.
