Authentic USGBC Certification Exam LEED-AP-ND Questions Answers

A snow storage system that uses collected snow in the winter to cool water for a neighborhood central plant during the summer would contribute to the Green Infrastructure and Buildings credit for Optimizing Building Energy Performance. This innovative system reduces the energy needed for cooling by utilizing natural, renewable resources, thereby enhancing the overall energy efficiency of the development.

Optimize Building Energy Performance Credit:This credit aims to reduce the energy demand of buildings through design strategies and technologies that improve energy efficiency. By optimizing energy use, projects can significantly lower their environmental impact and operational costs.

Snow Storage System:The snow storage system in question utilizes a natural process where snow, collected in winter, is stored and then used to cool water for a central plant in summer. This method reduces reliance on traditional, energy-intensive cooling systems such as air conditioning, thereby saving energy.

Renewable and Efficient Energy Use:This system aligns with the objectives of the Optimize Building Energy Performance credit by reducing the need for mechanical cooling. It is an example of how leveraging local climatic conditions and natural processes can contribute to sustainable building operations.

The LEED Reference Guide for Neighborhood Development provides guidelines on how innovative energy-saving strategies, like snow storage systems, can be applied to earn points under the Optimize Building Energy Performance credit.

TheLEED v4 Neighborhood Developmentdocumentation further elaborates on various energy optimization strategies that can be employed to enhance building performance.

These explanations provide a thorough understanding of how specific project features can contribute to earning LEED-ND credits and meeting sustainability goals.

For the Neighborhood Pattern and Design Credit for Tree-Lined and Shaded Streetscapes, Option 2: Shaded Sidewalks, the crown diameter of newly planted trees used in calculating the percentage of shaded sidewalks is based on their expected size 10 years after planting.

Shaded Sidewalks Credit:This credit aims to increase the comfort and usability of sidewalks by ensuring they are shaded, reducing heat exposure and improving the pedestrian experience. The shade coverage must be calculated based on the anticipated tree canopy.

Crown Diameter Calculation:LEED requires that the shading potential of newly planted trees be projected based on the tree’s expected crown diameter 10 years after planting. This approach ensures that the shading provided is realistic and sustainable over time.

Long-Term Planning:Using the 10-year crown diameter allows project teams to plan for the future growth of trees and ensure that sidewalks will be adequately shaded as the neighborhood matures. This long-term perspective is crucial for maintaining sustainable urban environments.

The LEED Reference Guide for Neighborhood Development specifies how to calculate tree canopy coverage and how future growth is factored into these calculations.

TheLEED v4 Neighborhood Developmentdocumentation provides additional guidelines on selecting tree species and projecting their growth.

Using air conditioning condensate for flushing toilets in all new buildings directly contributes to reducing indoor potable water use, which is the focus of the Green Infrastructure and Buildings (GIB) Credit for Indoor Water Use Reduction. This credit encourages the use of alternative water sources, such as air conditioning condensate, to minimize the consumption of potable water for non-potable uses. By implementing this strategy, the project can demonstrate significant reductions in potable water use, thereby helping to achieve the credit.
