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

The Integrative Process credit requires the project teams to perform analyses for both energy- and water-related systems from the predesign phase to the design and construction phase. The project teams should also identify and use opportunities to achieve synergies across disciplines and building systems.

This option requires the project to classify wood derived fuel as a recycled material that contributes towards the credit, because it is a waste material that is converted into a useful energy source1. Wood derived fuel can be used for heating, electricity generation, or co-firing with other fuels2. According to the LEED v4: Building Design + Construction Guide, recycled materials are those that have been reprocessed or remanufactured from recovered materials3.

The reuse calculation for MR Credit Building Life-Cycle Impact Reduction includes the surface area of structural elements that are reused in place or salvaged and reinstalled, such as floor decking, columns, beams, and roof decking. Exterior glazing and plumbing fixtures are not considered structural elements and are not included in the reuse calculation. Asbestos insulation is a hazardous material that should be removed and disposed of properly, not reused.

This alternative analysis can help the team check the impact of reducing the amount of concrete used in the building, which can affect several impact categories, such as global warming potential (GWP), acidification, and eutrophication1. Concrete is a material with high embodied energy and carbon emissions, and reducing its use can lower the environmental impact of the building2. Optimizing the slab depth can also improve the thermal performance and daylighting of the building, which can reduce the operational energy use and demand3.

The only stage of LEED for Neighborhood Development certification that is eligible for points under Building Design and Construction: New Construction, Location and Transportation Credit, LEED for Neighborhood Development Location, is LEED for Neighborhood Development Pilot, Stage 3 LEED for Neighborhood Development Certified Project. This is because the credit requires that the project be located within the boundary of a development that has achieved certification under LEED for Neighborhood Development (either Stage 2 or Stage 3 under the Pilot or 2009 rating systems, or Certified Plan or Certified Project under the LEED v4 rating system)1 The other stages listed in the question are either conditional approvals or pre-reviews that do not guarantee certification23 References: 1: LEED v4 Reference Guide for Building Design and Construction, Location and Transportation Credit: LEED for Neighborhood Development Location, page 460. 2: LEED for Neighborhood Development Location – Above Green 3 3: LEED v4: Building Design + Construction Guide - U.S. Green Building Council 1

The renewable energy option is economically feasible if the present value of the utility cost savings over the lifetime of the system is greater than or equal to the present value of the higher initial cost of the system. This means that the system will pay for itself and generate net savings in the long run. The utility cost savings depend on the amount of energy produced by the solar thermal panel, the price of natural gas, and the inflation rate. The higher initial cost depends on the size, type, and installation of the solar thermal panel.

LEED Reference Guide for Building Design and Construction v4

Exemplary Performance is not available for Option 2 of Location and Transportation Credit, Surrounding Density and Diverse Uses. According to the LEED v4 BD+C Reference Guide, this credit has two options: Option 1. Surrounding Density (5 points) and Option 2. Diverse Uses (1 point). Exemplary Performance is only available for Option 1, and it requires achieving a surrounding density of at least 405,000 square feet per acre (100,000 square meters per hectare)1. Option 2 does not have any Exemplary Performance criteria, and it only requires locating the project within a 1/2-mile (800-meter) walking distance of at least seven diverse uses2. References:

The Whole Building Simulation option is used to meet the Energy and Atmosphere Prerequisite, Minimum Energy Performance for a hospital project. This option involves creating a detailed computer model of the building to simulate its energy performance and identify opportunities for improvement.References: LEED AP Building Design + Construction (LEED AP BD+C) V4 resources 1
