What does not meet LEED requirements for minimizing the negative impacts of refrigerants on the environment?
A: Designing a building with natural ventilation
B: Selecting refrigerants with zero or low ozone depletion potential (ODP) and minimal global warming potential (GWP).
C: Designing a building that does not use chemical refrigerants
D: Reducing the annual leakage rate of refrigerants to 10% or less

参考答案: D

Notes:

Reference: LEED 2009 for New Construction and Major Renovations Rating System

A building that uses natural ventilation (also called passive cooling) does not use refrigerants. Examples of natural ventilation include the use of open windows. This strategy is often viable in cooler climates.

If a building does use chemical refrigerants the project team should try to select refrigerants with low ODP and GWP.

A building that does not use chemical refrigerants will not have a negative impact on the environment.

When phasing out CFC-based refrigerants or when a phase out is not economically feasible, LEED requires reducing the annual leakage of CFCs to 5% or less using EPA Clean Air Act procedures.

This applies to CFCs but any new building should not have a refrigeration system that leaks 10% of the refrigerant annually.
