Installing dual-flush toilets can significantly reduce indoor water demand. Dual-flush toilets have two flush options: a half flush for liquid waste and a full flush for solid waste. By using less water for liquid waste, these toilets can reduce overall water consumption by up to 30%, helping to achieve the owner’s water reduction goal. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

The scorecard is the recommended tool for the project team to utilize in order to determine the target certification level. The scorecard is a document that lists all the prerequisites and credits available for a specific rating system, along with their point values and requirements. The project team can use the scorecard to track their progress and estimate their potential score based on their design strategies and performance goals. The scorecard also helps the project team to identify synergies and trade-offs among different credits, prioritize their efforts, and optimize their resources.

The other options are not useful for estimating the certification level, as they are tools for documenting or clarifying specific credits or issues. The credit submittal form is a template that guides the project team on how to submit the required documentation for each credit. The project CIR (Credit Interpretation Request) is a service that allows the project team to ask technical questions or request clarifications on credit requirements or standards from USGBC or GBCI reviewers. The certification level cannot be determined without complete drawings, as they are necessary to demonstrate compliance with credit criteria.

Recycling is a strategy that can be used to reduce the amount of construction waste that is sent to landfills or incinerators. Recycling involves collecting, sorting, processing, and reusing or selling materials that would otherwise be discarded as waste. Recycling can save natural resources, reduce greenhouse gas emissions, create jobs, and lower disposal costs1 . References: LEED v4 Green Associate Candidate Handbook1, EPA’s Recycling Basics

The increase in air temperature in a developed area resulting from the dark surfaces of roadways, parking lots, and tarred rooftops is known as heat island effect. Heat island effect is a phenomenon whereby urban areas experience higher temperatures than rural areas due to the absorption and re-emission of solar heat by man-made surfaces. Heat island effect can have negative impacts on human health, energy consumption, air quality, and climate change. Some strategies to reduce heat island effect include increasing vegetation cover, using reflective or green roofs, using cool or permeable pavements, and enhancing natural ventilation.References: LEED v4 BD+C Reference Guide, Sustainable Sites, page 35 ; EPA Heat Island Effect website 1
