LEED-AP-BD+C Exam Dumps - LEED AP Building Design + Construction (LEED AP BD+C)

A rainwater harvesting system on site could be recognized in the Sustainable Sites Credit, Rainwater Management and the Water Efficiency Credit, Indoor Water Use Reduction. The Sustainable Sites Credit, Rainwater Management rewards projects that reduce runoff volume and improve water quality by replicating the natural hydrology and water balance of the site1. A rainwater harvesting system can help achieve this by capturing and reusing rainwater on site2. The Water Efficiency Credit, Indoor Water Use Reduction rewards projects that reduce indoor water consumption by installing water-efficient fixtures and fittings3. A rainwater harvesting system can help achieve this by providing an alternative source of water for non-potable uses such as toilet flushing and irrigation4.

The other options are not correct. The Water Efficiency Credit, Water Metering does not recognize rainwater harvesting systems, but rather requires projects to install permanent water meters that measure the total potable water use for the building and grounds. The Water Efficiency Prerequisite, Outdoor Water Use Reduction does not recognize rainwater harvesting systems, but rather requires projects to reduce outdoor water consumption by using plant species that are native or adapted to the region and by using irrigation systems that are efficient and properly controlled. The Water Efficiency Prerequisite, Indoor Water Use Reduction does not recognize rainwater harvesting systems, but rather requires projects to reduce indoor water consumption by 20% from the baseline by installing water-efficient fixtures and fittings.

This strategy would qualify as an innovation credit because it is not addressed in the LEED green building rating system, and it achieves significant, measurable environmental performance by educating the students and the community about the benefits of green building. The project team would need to identify the intent, requirements, submittals, and design approach of this strategy in the Basis of Design document1. This strategy is also listed as an example of innovation in the LEED Innovation Catalog2.

According to the LEED V5 : Building Design + Construction Guide, the Water Efficiency Prerequisite, Outdoor Water Use Reduction, Option 2. Reduced Irrigation, requires that a project’s landscape water requirement be reduced by at least 30% from the calculated baseline for the project site’s peak watering month. The baseline is determined by the Environmental Protection Agency (EPA) WaterSense Water Budget Tool, or a local equivalent for projects outside the U.S. The reduction must be achieved through plant species selection and irrigation system efficiency 1 .

This option requires the project team to focus on reducing the water consumption of the school project, because it is located in a basin that depends on the seasonal snowmelt for its water supply 1 .  Installing efficient plumbing fixtures, such as low-flow faucets, toilets, and showerheads, can help save water and reduce the demand on the local water resources 2 .  This option can also help the project achieve the LEED credits for outdoor and indoor water use reduction 3 .

Large commercial buildings are most often dominated by internal loads, which are the heat gains or losses from people, equipment, lighting, and other sources inside the building. Internal loads can affect the heating and cooling loads and the energy consumption of the building. Therefore, reducing internal loads can improve the building’s energy efficiency and performance.  References :

To comply with LEED BD+C Indoor Environmental Quality (IEQ) Credit: Enhanced Indoor Air Quality Strategies, Option 2 , a project must implement at least two of the following enhanced air quality strategies:

Use of an outdoor airflow measurement device to monitor and measure at least 90% of the outdoor air intake flow to ensure proper ventilation.

Advanced filtration systems (such as CEN Class F7 or MERV 13 filters) for mechanically ventilated buildings.

Carbon dioxide (COâ‚‚) monitoring in densely occupied spaces, with alerts for elevated COâ‚‚ levels.

Entryway systems (such as walk-off mats) at all regularly used building entrances to reduce dirt and contaminants.

Option D correctly identifies outdoor airflow measurement as one of the acceptable strategies under Option 2 .

The credit may be achieved by using nonroof measures only, such as shading, paving, and vegetation, to reduce the heat island effect on the site. The credit does not require a highly reflective roof for all projects, but allows for flexibility and trade-offs depending on the climate and design conditions. The project can use the Heat Island Reduction 1 to demonstrate compliance with the credit requirements. The credit is feasible and applicable for this project, and does not need an alternative compliance path.

The Indoor Air Quality Assessment credit under LEED V5 .1 BD+C rating system (Building Design and Construction) seeks to establish better quality indoor air in the building after construction and during occupancy. The credit provides two options for compliance, which cannot be combined 1 . Therefore, Indoor Environmental Quality test results would be required for credit compliance.
