LEED AP Building Design and Construction (BD+C) Practice Exam

What is the minimum number of cooling tower cycles needed to earn 2 points?

1. 5 cooling tower cycles

2. 7 cooling tower cycles

3. 10 cooling tower cycles

4. 12 cooling tower cycles

The correct answer is: 10 cooling tower cycles

To earn 2 points in the Water Efficiency category for cooling tower management under the LEED BD+C rating system, it is essential to achieve a minimum of 10 cooling tower cycles. The rationale for this requirement is based on improving water efficiency and sustainability. By increasing the number of cycles, the amount of water needed for evaporation is reduced, leading to lower water consumption and better overall resource use in building operations. The principles of water conservation are a crucial aspect of sustainable building practices, and cooling tower performance directly impacts water usage efficiency. A higher number of cycles indicates a reduction in fresh water intake and can help mitigate the environmental impacts associated with water extraction and distribution. In contrast, lower cycle counts—such as 5, 7, or even 12—would not satisfy the criteria required to achieve said points. The thresholds for points are carefully calibrated based on benchmarks that reflect effective water use efficiency strategies, guiding designers and builders towards more sustainable practices. Consequently, achieving at least 10 cycles is necessary to meet the LEED standards for sustainability in this context.
