Closed systems are systems that promote the conservation of materials and resources by linking elements in order to form relationships with their function. Closed systems aim to minimize waste, energy loss, and environmental impact by reusing, recycling, or regenerating materials within the system boundaries. Closed systems can be inspired by natural ecosystems, where waste from one process becomes food for another process. An example of a closed system is a building that collects rainwater for irrigation, uses solar panels for electricity, composts organic waste forfertilizer, and recycles greywater for flushing toilets1 . References: LEED v4 Green Associate Candidate Handbook1, Biomimicry Institute’s What is Biomimicry?

Greenwashing is a term that describes misinformation presented to consumers to portray a product or policy as being more environmentally friendly than it is. Greenwashing can be done by using vague or misleading claims, false labels or certifications, irrelevant or exaggerated benefits, or hidden trade-offs. Greenwashing can deceive consumers into buying products or supporting policies that are not trulygreen, and undermine the credibility and effectiveness of genuine green initiatives1 . References: LEED v4 Green Associate Candidate Handbook1, EPA’s Greenwashing

Biomass is a renewable energy source that can be used to produce electricity from organic plant and waste material. It is considered green power by the U.S. EPA because it provides environmental benefits and reduces greenhouse gas emissions12.

Pervious paving, also known as permeable paving, allows water to pass through it, facilitating the recharging of aquifers. This type of paving reduces runoff by allowing water to soak into the ground, which can help replenish groundwater supplies and reduce the impact on nearby water bodies. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources
