Question
Which of the following falls under the Energy and Atmosphere credit category?
A. Interior Lighting
B. Heat Island Reduction
C. Cooling Tower Water Use
D. Enhanced Refrigerant Management
Answer
D. Enhanced Refrigerant Management
Explanation
The Energy and Atmosphere (EA) category addresses the energy performance, efficiency, and renewable sources of buildings. One of the credits in this category is EA Credit: Enhanced Refrigerant Management, which aims to reduce the emissions of ozone-depleting substances and greenhouse gases from refrigeration and air-conditioning equipment.
Refrigerants are substances that are used to transfer heat in cooling systems. Some refrigerants have high global warming potential (GWP) and ozone depletion potential (ODP), which means they can contribute to climate change and damage the ozone layer if they leak or are improperly disposed of. Enhanced refrigerant management involves selecting refrigerants with low GWP and ODP, minimizing refrigerant charge size, and preventing or detecting leaks.
The Energy and Atmosphere (EA) credit category in LEED certification focuses on strategies to reduce energy consumption, increase energy efficiency, and minimize the environmental impact of building systems. Enhanced Refrigerant Management is a credit within the EA category that addresses the use of refrigerants in HVAC&R systems.
The goal of Enhanced Refrigerant Management is to reduce ozone depletion and support early compliance with the Montreal Protocol while minimizing direct contributions to climate change. This credit encourages the use of refrigerants with low global warming potential (GWP) and ozone depletion potential (ODP), as well as the proper handling and disposal of refrigerants.
The other options given in the question are not directly related to the Energy and Atmosphere credit category:
A. Interior Lighting falls under the Indoor Environmental Quality (IEQ) category, which focuses on enhancing the indoor environment for occupants.
B. Heat Island Reduction is part of the Sustainable Sites (SS) category, which addresses strategies to minimize the impact of the building on the surrounding environment.
C. Cooling Tower Water Use is not a specific LEED credit but may be addressed under the Water Efficiency (WE) category, which aims to reduce water consumption and increase water efficiency in buildings.
By understanding the focus and goals of each credit category, LEED professionals can effectively navigate the certification process and implement sustainable strategies in building projects.
