What is a common sustainable practice in HVACR system design?

Incorporating energy-efficient components and materials is a fundamental sustainable practice in HVACR system design because it significantly reduces energy consumption and greenhouse gas emissions. By selecting equipment that operates more efficiently, such as high SEER (Seasonal Energy Efficiency Ratio) air conditioners, or using advanced heat pump technology, the overall energy demand of the system is lowered. This not only benefits the environment but also decreases operating costs for the homeowner or business over time, making it a financially sound decision as well. Additionally, using sustainable materials, such as refrigerants with lower global warming potential or recyclable insulation, contributes further to the overall sustainability of the HVACR design.

In contrast, utilizing outdated materials and limiting the use of technology would negate advancements in efficiency and could lead to increased energy use and higher emissions. High-performance fans, while beneficial, do not encompass the broader approach required for sustainable HVACR design, which involves an integrated system of energy management across all components.
